¿Será realmente una verdadera comunicación interventricular? / Could it really be a true ventricular septal defect?

Ventricular septal defect (VSD) is one of the most common congenital defects. It has a wide variety of clinical spectrum of presentation depending on the location and size of the defect. Generally, small restrictive VSDs present spontaneous closure during follow-up. A clinical case is presented with suspected persistent perimembranous VSD, with described intraoperative anatomical findings of aneurysmal cribriform membrane, ruling out VSD.

La comunicación interventricular (CIV) es uno de los defectos congénitos más comunes. Tiene una amplia variedad de espectro clínico de presentación dependiendo de la localización y tamaño del defecto. Por lo general, en los CIV restrictivos pequeños presentan un cierre espontáneo durante el seguimiento. Se presenta un caso clínico con sospecha de CIV perimembranosa persistente, con hallazgos anatómicos intraoperatorios descritos de membrana cribiforme aneurismática descartandose CIV.

Impacto de la miectomía septal ampliada sobre los cambios ecocardiográficos en la miocardiopatía hipertrófica obstructiva / Impact of Extended Septal Miectomy on Echocardiographic Changes in Hypertophic Obstructivec Cardiomyopathy

RESUMEN Introducción: La miectomía septal ampliada (MSA) ha demostrado ser una estrategia útil para mejorar los síntomas de los pacientes con miocardiopatía hipertrófica obstructiva (MCHO). Objetivos: El objetivo de este trabajo fue analizar el impacto de la MSA en parámetros estructurales y funcionales ecocardiográficos a corto y mediano plazo, en pacientes con MCH y obstrucción dinámica del tracto de salida del ventrículo izquierdo (VI). Material y métodos: Se analizaron los ecocardiogramas en los períodos preoperatorio, postoperatorio inmediato (1 mes post cirugía) y posoperatorio alejado (2 a 3 años) de pacientes sometidos a MSA. Resultados: Se intervinieron 94 pacientes con una edad media de 57,6 ± 13,8 años. Se observó una reducción significativa del máximo espesor septal en el postoperatorio inmediato, que se mantuvo en el posoperatorio alejado, y en el tamaño auricular izquierdo en el postoperatorio inmediato que se profundizó en el alejado (p < 0,001). El gradiente intraventricular en reposo pasó de 49,2 mmHg basal a 6,4 mmHg (p < 0,001) y de allí a 4,6 mmHg (p=0,224) en los períodos inmediato y alejado, y con la maniobra de Valsalva de 93,9 mmHg a 8,7 mmHg (p < 0,001) y de allí a 7,2 mmHg (p=0,226) respectivamente. La función diastólica fue valorada como grado II en el 58,5 % de los pacientes en el preoperatorio, 51,7 % en el postoperatorio inmediato y 29 % en el postoperatorio alejado. En la misma línea se evidenció un cambio en la relación E/e´ y la presión sistólica pulmonar, grado de insuficiencia mitral y dimensiones de la aurícula izquierda. Conclusión: En esta cohorte de pacientes con MCHO, la realización de una MSA se asoció a una mejoría significativa de la función diastólica del VI, reducción de las presiones de llenado y pulmonares y grado de insuficiencia mitral, y remodelado reverso de la aurícula izquierda. Es posible que esta combinación de efectos explique los beneficios clínicos de la intervención.

ABSTRACT Background: Extended septal myectomy (ESM) has proven to be a useful strategy to improve symptoms in patients with hypertrophic obstructive cardiomyopathy (HOCM). Objectives: The aim of this study was to analyze the impact of ESM on short and mid-term structural and functional echocardiographic parameters in patients with HCM and left ventricular (LV) outflow tract dynamic obstruction. Methods: Preoperative, immediate postoperative (1 month after surgery) and late postoperative (2 to 3 years) echocardiograms of patients undergoing ESM were analyzed. Results: A total of 94 patients with mean age of 57.6 ± 13.8 years underwent surgery. A significant reduction was observed in maximum septal thickness in the immediate postoperative period, which was sustained in the late postoperative period, and in atrial size in the immediate postoperative period, which deepened in the late postoperative period (p < 0.001). Intraventricular gradient at rest dropped from 49.2 to 6.4 mmHg (p < 0.001) and then to 4.6 mmHg (p=0.224) in the immediate and late periods and with Valsalva maneuver from 93.9 to 8.7 mmHg (p < 0.001), and then to 7.2 mmHg (p=0.226), respectively. Preoperative diastolic function was assessed as grade II in 58.5% of patients, decreasing to 51.7% in the immediate postoperative period and to 29% in the late postoperative period. In agreement with these results, a change was evidenced in the E/e´ ratio and pulmonary artery systolic pressure, degree of mitral regurgitation and left atrial dimensions. Conclusion: In this cohort of patients with HOCM, ESM was associated with a significant improvement in LV diastolic function, reduction in filling and pulmonary pressures and degree of mitral regurgitation, and left atrial reverse remodeling. It is possible that this combination of effects explains the clinical benefits of the intervention.

Clinical efficacy of Amplatzer duct occluder-Ⅱ device for the treatment of ventricular septal defect with aortic sinus prolapse in child patients / 介入放射学杂志

Objective To investigate the efficacy of Amplatzer duct occluder-Ⅱ device(ADO-Ⅱ)in treating ventricular septal detect(VSD)with aortic sinus prolapse(ASP)in child patients.Methods The clinical data of 94 child patients with VSD complicated by ASP,who were admitted to the Hunan Provincial Children's Hospital of China between January 2018 and September 2022,were retrospectively collected.The child patients included 60 males and 34 females with a mean age of(4.7±3.1)years.Mild-moderate ASP was seen in 83 child patients,with a mean(4.12±0.97)mm-sized VSD.Severe ASP was seen in 11 child patients,with a mean(4.95±0.51)mm-sized VSD.Perimembrane VSD was observed in 54 child patients and intracristal VSD in 40 child patients.The relationship of VSD size and degree of ASP to the selection of ADO-Ⅱ,postoperative middle period aortic valve regurgitation and residual leakage was analyzed,so as to clarify the applicability of ADO-Ⅱ to such child patients.Results In the postoperative middle period,6 child patients had mild aortic valve regurgitation,most seen in the child patients who received 4-4 mm or 5-4 mm ADO-occluder;and 10 child patients had residual leakage,mainly seen in the child patients who received 5-4 mm or 6-4 mm occluder.Conclusion In the condition when the ADO-Ⅱ occluder shows satisfactory placement pattern,this treatment is suitable for the child patient having＜6 mm VSD with ASP.Although there are some residual leakage and aortic valve regurgitation after surgery,this interventional therapy still meets the clinical requirements.(J Intervent Radiol,2024,32:17-21)

Analysis of Surgical Treatment of 20 Cases of Ebstein's Anomaly Combined with Atrial Septal Defect / 昆明医科大学学报

Objective To analyze the treatment strategy of the atrial septal defect in the surgical treatment of Ebstein's anomaly combined with the atrial septal defect and the short-term follow-up results of the treatment of Ebstein's anomaly.Methods A retrospective analysis of the clinical data and follow-up results of 20 patients with Ebstein's anomaly and atrial septal defect was conducted from September 2017 to February 2021.And the statistical analysis on the preoperative and postoperative echocardiography results of this group of patients was performed.Results Sixteen patients underwent the biventricular correction surgery,among whom two cases underwent the horizontal atrial tricuspid valvuloplasty(Danielsons procedure),four cases underwent the vertical atrial tricuspid valvuloplasty(Carpentier procedure),and ten cases underwent the conical reconstruction.Two patients were given a half ventricular correction surgery(tricuspid valve reconstruction combined with bidirectional Glenn surgery)and two patients underwent the bidirectional Glenn surgery.The combined atrial septal defects were closed in one stage during extracorporeal circulation for correction of deformitie in 20 patients.At 1,3,6,and 12 months after the surgery,the patient's right ventricular size significantly decreased compared to preoperative(P<0.05),and cardiac function(left ventricular ejection fraction)significantly improved(P<0.05).Conclusion The surgical treatment of Ebstein's anomaly combined with the atrial septal defect should follow the principle of individualized treatment.Biventricular correction is still the first choice for the treatment of Ebstein's anomaly,and the atrial septal defect should be closed at one stage,so as to obtain a good therapeutic effect.

Interventional Treatment of Muscular Ventricular Septal Defect in Children / 昆明医科大学学报

Objects To explore the effectiveness and safety of using the Cardio-O-Fix Plug occluder in the treatment of muscular ventricular septal defect(mVSD)in children.Methods 14 patients with mVSD were taken to the cardiology department of First Affiliated Hospital of Kunming Medical University from July 2015 to June 2021 as research subjects.They were divided into two groups:14 children who received Cardi-O-Fix Plug occluder as the experimental group,and 10 children who received Cardi-O-O-Fix mVSD occluder as the control group.Electrocardiogram and transthoracic echocardiography were used to evaluate the occlusive efficacy and incidence of complications 1 day after surgery and 1 month,3 months,and 6 months of follow-up.Results Among the 24 pediatric patients,22 cases were successfully occluded,and 2 cases were unsuccessful(1 in the experi-mental group and 1 in the control group).The success rate of the experimental group was 92.8%(13/14),while the success rate of the control group was 90.0%(9/10).The average surgical duration of the experimental group was(71.93±14.85)minutes,while the average surgical duration of the control group was(90.70±19.78)minutes.There was a significant statistical difference between the two groups(P<0.05).Both the experimental group and the control group did not experience serious complications during surgery and follow-up.There was no significant difference in cardiac ultrasound indicators(including left ventricular ejection fraction,left ventricular end-diastolic diameter,and pulmonary artery pressure)between the two groups at different time points(P>0.05).Conclusion Trans-catheter closure of mVSD using Cardi-O-Fix Plug occluder in children is both safe and effective.The incidence of arrhythmia is low in the short,medium and long term.

Evaluation of myocardial structure and function in patients with hypertrophic obstructive cardiomyopathy via cardiac MR after ultrasound-guided interventional therapy / 实用放射学杂志

Objective To evaluate the change of cardiac structure and function in patients with hypertrophic obstructive cardiomyopathy(HOCM)after ultrasound-guided percutaneous intramyocardial septal radiofrequency ablation(PIMSRA)via cardiac magnetic resonance(CMR).Methods Patients with HOCM who underwent PIMSRA,echocardiography and CMR preoperative scanning and one year after surgery were analyzed retrospectively.Myocardial structural and functional parameters were measured by Circle cardiovascular imaging post-processing software.The changes of myocardial parameters before and after surgery were compared by using paired sample t-test and Chi-square test.Results Compared with the preoperative assessment,patients'clinical symptoms and the cardiac function were significantly improved one year after surgery.The left ventricular outflow tract pressure gradient(LVOT-PG)was significantly decreased and length of mitral regurgitation was shortened one year after surgery compared with before surgery via ultrasound(P<0.05).Compared with the preoperative assessment,CMR showed that patients with end-systolic volume of left atrium,minimum volume of left atrium,transverse diameter of left atrium,thickness of ventricular septum and free wall of left ventricular at end-systolic section were significantly reduced,and left ventricular mass(LVM)was significantly decreased one year after surgery,with statistical significance between before and after surgery(P<0.001).One year after surgery,the left atrium ejection fraction(LAEF)was significantly increased(P<0.05),the maximum slope and the maximum signal intensity of the ventricular septum and the left ventricular free wall of the papillary muscle were significantly increased(P<0.001),and the peak time was significantly decreased(P<0.001)compared with before surgery.Conclusion After PIMSRA treatment,the systolic function of left atrium in HOCM patients is improved,and the microcirculation perfusion of left ventricular is significantly improved.

Incidence and influencing factors of right-to-left shunt in iatrogenic atrial septal defect after interventional therapy for atrial fibrillation / 中华老年心脑血管病杂志

Objective To investigate the incidence and influencing factors of right-to-left shunt(RLS)in patients with iatrogenic atrial septal defect(iASD)after atrial septal puncture during in-terventional therapy for atrial fibrillation and analyze the correlation with new onset migraine in order to provide a basis for the prevention and treatment of related clinical events.Methods A to-tal of 54 patients with atrial fibrillation who underwent interventional surgery[including radio-frequency catheter ablation(RFCA),left atrial appendage closure(LAAC),and'one-stop'sur-gery]in cardiologic department of our hospital from November 2022 to March 2023 were enrolled in this study.According to existence of RLS in iASD within 48 h after surgery,they were divided into RLS group(24 patients)and non-RLS group(30 patients).The general information and tran-sthoracic echocardiographic data were collected and analyzed for the occurrence and influencing factors of RLS.The incidence of new onset migraine within 3 months after operation was recorded in both groups.Results All these patients had left-to-right shunt of iASD,24 patients had RLS(44.44％),and the defect size was 5.12±0.80 mm.During the 3 months'follow-up period,there was no significant difference in the incidence of new onset migraine between the two groups(P＞0.05).Older age,increased proportion of persistent atrial fibrillation,and larger iASD size was seen in the RLS group than the non-RLS group(P＜0.05,P＜0.01).Multivariate logistic regres-sion analysis showed that iASD size was a risk factor for RLS(OR=2.245,95％CI:1.040-4.846,P=0.040).Conclusion RLS is common in iASD after interventional treatment of atrial fibrillation,which is not related to the early occurrence of new onset migraine in these patients.The size of iASD is a risk factor for RLS.At the same time,more attention should be paid to the influence of iASD on hemodynamics and clinical events.

Optimal repair timing and predictors of death in patients with ventricular septal rupture post myocardial infarction / 中华胸心血管外科杂志

Objective:The main objective of this study was to analyze the optimal timing for repair of post-AMI ventricular septal rupture(VSR). Secondary endpoints were to determine which factors could influence in-hospital mortality in the patients with VSR.Methods:We designed an observational, retrospective study, selecting 100 patients with post-AMI VSR between January 1, 2019 and August 31, 2023, with inclusion and exclusion criteria. Analyzed the usefulness and appropriate timing of surgery in this patient cohort. Compared the background characteristics, treatment and laboratory data between survival and death group. The risk factors for in-hospital mortality were assessed using multivariate analysis with a logistic regression model. Results:The overall in-hospital mortality rate was 56%, the mortality rate of surgical patients was 34.9%, and the mortality rate of conservative patients was 91.9%. Patients operated on very early(0-3 days) had significantly poor results with a mortality rate of 63.6% while those operated within 2 weeks, had a mortality rate of 38.1%, and those operated later(>14 days) showed 22.6% mortality.There were statistically significant differences between the two groups in terms of heart rate, ratio of revascularization , size of VSR, shock stage and severity of coronary artery lesions( P<0.05), and the C-reactive protein, WBC count, BNP level, creatinine level and blood lactate level in the death group were higher than those in the survival group( P<0.05). Logistic regression analysis revealed that the level of white blood cell count, lactate and brain natriuretic peptide were independent risk factors for in-hospital mortality. Conclusion:In our study, we observed that surgery is the definitive therapy for the majority of patients.For patients who are hemodynamically stable and have compensated heart failure, there may be more benefit from delayed ventricular septal rupture repair. The risk factors for in-hospital mortality were the elevated lactate levels, BNP levels and WBC count.

Effect of backfilling in correction of malformation of lacrimal sulcus and blepharobuccal sulcus after removal and treatment of orbital septum cellulite through intraocular pouch of lower eyelid / 中华医学美学美容杂志

Objective:To investigate the effect of backfilling on the deformity of lacrimal sulcus and blepharobuccal sulcus after special treatment of the fat from orbital septum of the pouch in the lower intra-palpebral approach.Methods:From November 2019 to September 2022, a total of 42 patients (13 males and 29 females) aged 16-47(23.8±6.9) years with orbital septal fat swelling were treated by the surgical department of Beijing Huangsi Medical Cosmetic Clinic after the removal of orbital fat mass by the intraocular pouch approach. With mild, moderate, and severe lacrimal sulci and blepharobuccal depression deformity, the lower eyelid skin was not relaxed. The naturally herniated orbital septal adipose mass was cut off through the lower eyelid conjunctival incision approach, and then granulated into a 1 ml syringe, which was accurately filled into the depressed area of lacrimal sulci and blepharobuccal sulci according to the depressions marked before surgery.Results:The incisions of all 42 patients healed in the first stage without hematoma and infection, and the subcutaneous ecchymosis of 2 cases was observed by local hot compress 48 h later and the ecchymosis subsided 1 week. Follow-up was performed at 1 month, 2 months and 3 months, respectively. Among them, 35 patients underwent the operation of removing the lower eyelid bag and orbital septum cellulite and backfilling to correct the malformation of lacrimal sulci, and the postoperative effect was satisfactory. The symptoms of puffed eye bags, blepharobuccal sulci and lacrimal sulci depression disappeared, and the wound healed in one stage. 7 patients with eye bags accompanied by lacrimal sulci and blepharobuccal sulci were told before surgery that they might need two fat fillings due to insufficient fat content in the orbital septa and slight indentations. One month later, granular fat was taken from the legs to fill the lacrimal sulci and blepharobuccal sulci with satisfactory results.Conclusions:The treatment after the removal of orbital septum cellulite and the correction of lacrimal sulcus and blepharobuccal sulcus deformity are simple and satisfactory, and worthy of clinical application.

Additional tricuspid valve annuloplasty versus isolated closure for atrial septal defect with secondary moderate to severe tricuspid regurgitation: A propensity score matching study / 中国胸心血管外科临床杂志

@#Objective To compare the efficacy of additional tricuspid valve annuloplasty (TVP) and isolated closure for atrial septal defect (ASD) with moderate to severe tricuspid regurgitation (TR). Methods Clinical data of the patients diagnosed with ASD combined with secondary moderate to severe TR and treated in our hospital from January 2009 to June 2020 were retrospectively analyzed. Patients were divided into a TVP group and a non-TVP group based on whether TVP was performed simultaneously. The baseline data of two groups were matched with a ratio of 1∶1 propensity score. Results A total of 32 pairs from 257 patients were successfully matched. In the TVP group, there were 24 females and 8 males with an average age of 44.0±13.1 years. In the non-TVP group, there were 28 females and 4 males with an average age of 44.5±11.6 years. The TR area and estimated pulmonary artery pressure in the two groups were significantly decreased compared with preoperation (all P<0.001). The TR area (P=0.001) and the estimated pulmonary artery pressure (P=0.002) were decreased more significantly in the TVP group than those in the non-TVP group. Linear regression analysis showed that age and preoperative TR area had a positive correlation with TR area at follow-up (β=0.045 and 0.259, respectively, both P<0.05), while additional TVP had a negative correlation (β=–1.542, P=0.001). Conclusion Additional TVP can significantly reduce the TR area and pulmonary artery pressure, and elderly patients with severe TR before surgery should actively receive TVP.

A Case of Ross Procedure for Aortic Regurgitation due to Prolapse of a Right Coronary Cusp Caused by Natural Closure of Ventricular Septal Defect / 日本心臓血管外科学会雑誌

A 44-year-old man had been pointed out to have a heart murmur during his elementary school days. He came to us complaining of chest pain and palpitation. He was diagnosed to have severe aortic regurgitation caused by prolapse of the right coronary cusp, and the left ventricular function was depressed. At surgery, the aortic valve was repaired with the RCC resuspension technique, but regurgitation was not controlled because the RCC annulus was retracted by natural supracristal closure of the ventricular septal defect. We proceeded to the Ross procedure. A pulmonary autograft was harvested and sewed in the aortic annulus. The right ventricular outflow tract was reconstructed using a stentless bioprosthetic valve with glutaraldehyde-treated bovine pericardium. He was discharged after a straightforward postoperative course.

A Case of Infective Endocarditis Treated with Ventricular Septal Defect Closure with the Sandwich Method, Aortic Valve Replacement, and Tricuspid Valve Replacement / 日本心臓血管外科学会雑誌

A 74-year-old man was diagnosed with infective endocarditis (IE) involving the aortic and tricuspid valves, ventricular septal defect (VSD), and complete atrioventricular block. He was admitted to a previous hospital with complaints of fever and neck pain, and he developed complete atrioventricular block during the course of his illness. An echocardiogram revealed severe aortic regurgitation, aortic valve vegetations, and a ventricular septal defect. He was then transferred to our hospital, and he underwent emergent surgery. The aortic valve cusps were calcified and thick, with significant cusp destruction. The vegetations partly extended to the subvalvular area of the right and non-coronary cusp. The vegetations also extended from the atrial septum to the tricuspid valve septal leaflet and perimembranous VSD. Ventricular septal reconstruction using the sandwich technique with two bovine pericardial patches, aortic valve replacement, and tricuspid valve replacement were performed. Postoperatively, he received antibiotic therapy for six weeks and was discharged from our hospital after the implantation of a cardiac resynchronization therapy pacemaker. Echocardiography showed no residual shunts. Our case suggests that the sandwich technique can be a useful method of septal reconstruction for IE with extensive destruction of the ventricular septum.

A Case of Ventricular Aneurysm in a Remote Stage after Repair of a Ventricular Septal Perforation with Massive Thrombus in the Aneurysm / 日本心臓血管外科学会雑誌

A 71-year-old woman underwent repair of a ventricular septal perforation due to myocardial infarction by the extended sandwich patch technique 5 years ago. She was discharged from the hospital without complications. During the follow-up period, a ventricular apical aneurysm was found on contrast-enhanced computed tomography and transthoracic echocardiography. Since the aneurysm had enlarged gradually and a thrombus was found in it, repairing surgery was indicated. The patient was initiated on cardiopulmonary bypass after dissection of the adhesions of the previous surgery, and a longitudinal incision was made on the left side of the left anterior descending artery under cardiac arrest to remove the aneurysm. A large amount of thrombus was found inside the aneurysm. The thrombus was removed, Dor surgery was performed with a circular Hemashield patch. Reports of ventricular apical aneurysm after myocardial infarction in a remote period are rare. It is necessary to perform surgical intervention as soon as possible to prevent free wall rupture as well as cerebral infarction.

Exploring the hemodynamic changes of the ascending aorta before and after interventricular septal myocardial resection in obstructive hypertrophic cardiomyopathy by CMR 4D Flow technology / 中国医师杂志

Objective:To investigate the hemodynamic changes in the ascending aorta (AAo) before and after interventricular septal myocardial resection in obstructive hypertrophic cardiomyopathy (HOCM) using cardiac magnetic resonance four-dimensional blood flow (CMR 4D Flow) technology.Methods:HOCM patients who underwent interventricular septal myocardial resection at Guangdong Provincial People′s Hospital from May 2021 to September 2022 were prospectively included. Age and gender matched healthy volunteers (control group) were included during the same period. Both the control group and HOCM patients underwent CMR examination (including cine sequence and 4D Flow sequence) before and 6 months after surgery. CMR 4D flow technology was used to evaluate changes in AAo preoperative and postoperative blood flow patterns (eddy currents, spiral flow), maximum energy loss (EL max), and average energy loss (EL avg). HOCM patients underwent laboratory tests, including N-terminal pro-brain natriuretic peptide (N-pro BNP) and high-sensitivity troponin T (hsTnT). At the same time, the correlation between postoperative energy loss in HOCM patients and the degree of improvement in laboratory biomarkers was explored. Results:A total of 15 HOCM patients and 15 healthy volunteers were included. (1) In terms of blood flow patterns, the preoperative spiral flow degree of HOCM patients was significantly higher than that of the control group ( P=0.001), but the postoperative difference was not statistically significant ( P=0.059). The degree of eddy currents in HOCM patients before and after surgery was higher than that in the control group (all P<0.05). (2) In terms of energy loss, the preoperative EL max [21.17(14.30-28.10)mW vs 10.17(7.66-13.07)mW, P<0.001] and EL avg [4.87(3.46-5.77)mW vs 2.27(2.19-2.27)mW, P=0.023] of HOCM patients were higher than those of the control group, but there was no statistically significant difference between the postoperative and control groups (all P>0.05). Compared with preoperative, the postoperative EL max [12.33(8.70-17.41)mW] and EL avg [3.10(2.25-4.40)mW] of AAo in HOCM patients were significantly reduced (mean P=0.001). (3) Correlation analysis showed that there was a positive correlation ( r=0.587, P=0.021) between the EL max of AAo and the degree of improvement in hsTNT after interventricular septum myocardial resection, but no significant correlation ( r=0.229, P=0.413) with the degree of improvement in NT-pro BNP. Conclusions:The degree of postoperative AAo blood flow disorder in HOCM patients is reduced, and EL max and EL avg are significantly reduced. The EL max of postoperative AAo is positively correlated with the degree of improvement in hsTNT, suggesting that EL max may be applicable for prognostic evaluation of patients.

Transesophageal echocardiography for guiding left atrial appendage closure with LAmbre occluder / 中国医学影像技术

Objective To observe the value of transesophageal echocardiography(TEE)for guiding left atrial appendage closure(LAAC)with LAmbre occluder.Methods Data of 40 non-valvular atrial fibrillation(NVAF)patients who underwent LA AC with LAmbre occluder were retrospectively analyzed.CT angiography(CTA)before treatment,TEE and digital subtraction angiography(DSA)findings during LAAC were comparatively observed,and the correlations of the anchor area diameter and left atrial appendage opening diameter measured with the above three as well as occluder size were analyzed,and TEE and DSA for evaluating peri-device leak(PDL)were compared.Results LAAC were successfully performed with LAmbre occlude in all 40 cases.The diameter of the fixed umbrella was positively correlated with anchor area diameter measured with CTA,TEE and DSA(r=0.79,0.82,0.91,all P＜0.01),of occlusion umbrella was positively correlated with left atrial appendage opening diameter measured with CTA,TEE and DSA(r=0.56,0.89,0.86,all P＜0.01).Immediately after the release of occluder in LAAC,PDL occurred in 16 cases and were detected with both TEE and DSA,while in the rest 24 cases no PDL was found with neither TEE nor DSA.Conclusion TEE had comparable value to DSA for guiding LAAC using LAmbre occluder.

Defecto septal ventricular postinfarto: complicación devastadora / Post-infarction ventricular septal defect: a devastating complicatio

Introducción: la comunicación interventricular es la complicación mecánica más frecuente después de un infarto agudo del miocardio en especial si cursa con elevación del ST, cuya frecuencia es alrededor de 0.21%, aumentando cuando es extenso y no reperfundido en pacientes con mayor edad, si hay compromiso multivaso y sin colateralidad; es una situación devastadora de mal pronóstico. Presentación de los casos: se describen 2 casos en un hospital universitario de Bogotá posteriores a infarto agudo del miocardio con elevación del ST y sin reperfusión temprana, ambos en choque cardiogénico, el primero con evolución tórpida y mortalidad temprana y la segunda fue llevada a los 10 días a cierre transcatéter, documentándose periprocedimiento un aumento significativo del tamaño del defecto septal, con mayor inestabilidad hemodinámica y muerte posterior al cierre.

Introduction: ventricular septal communication is the most frequent mechanical complication of acute myocardial infarction (MI), especially if associated with ST-segment elevation, featuring a rate of around 0.21%, which increases in older patients with extensive defects and no reperfusion therapy. In patients with multivessel involvement and no collateral circulation; it is a catastrophic situation which carries a poor prognosis. Case reports: two patients admitted to a university hospital in Bogotá, with ST-elevation post-MI VSD, undergoing no early reperfusion, both in cardiogenic shock. The first patient had a torpid evolution and early mortality. The second patient underwent a VSD transcatheter repair 10 days after MI, determining significant periprocedural increase in the size of the septal defect, with greater hemodynamic instability and death.

Application of Computed Tomography Angiography in Preoperative Diagnosis of Coarctation of Aorta and Evaluation of Aortic Dilatation in Infants

ABSTRACT Objective: To evaluate the occurrence of aortic dilatation and its associated predictors with coarctation of the aorta (CoA) in infants using multi-slice computed tomography (MSCT). Methods: The clinical data of 47 infantile patients with CoA diagnosed by MSCT and 28 infantile patients with simple ventricular septal defect were analyzed retrospectively. Aortic diameters were measured at six different levels, and aortic sizes were compared by z score. The coarctation site-diaphragm ratio was used to describe the degree of narrowing. Relevant clinical data were collated and analyzed. Results: The dilation rate and z score of the ascending aorta in the severe CoA group were significantly higher than those in the mild CoA group (11 [52.38%] vs. 21 [80.77%], P=0.038 and 2.00 ± 0.48 vs. 2.36 ± 0.43, P=0.010). Pearson's correlation analysis found that the z score of the ascending aorta was negatively correlated with the coarctation site-diaphragm ratio value (r=-0.410, P=0.004). A logistic retrospective analysis found that an increased degree of coarctation was an independent predictor of aortic dilatation (adjusted odds ratio 0.002; 95% confidence interval 0.00-0.819; P=0.043). The z score of the ascending aorta in the severe CoA group was significantly higher than that in the ventricular septal defect group (P<0.05). Conclusion: Most infants with CoA can also have significant dilatation of the ascending aorta, and the degree of this dilatation is related to the degree of coarctation. Assessment of aortic diameter and related malformations by MSCT can predict the risk of aortic dilatation in infants with CoA.

The Impact of Transcatheter or Surgical Defect Closure on Self-Reported Sleep Quality in Adults with Atrial Septal Defect

ABSTRACT Objective: Sleep quality in those with cardiovascular disease is significantly lower than in the general population. This study aimed to explore the effect of transcatheter or surgical closure of atrial septal defect (ASD) on sleep quality. Methods: One hundred nineteen adult patients with ASD who underwent transcatheter or surgical closure were included in the study. Sleep quality was investigated prospectively just before defect closure and six months after defect closure. Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality of these patients. Results: PSQI scores were similar in both groups before the procedure in patients who underwent both transcatheter and surgical closure. The PSQI scores six months after transcatheter closure was significantly improved compared to the PSQI score before transcatheter ASD closure (3.5 ± 2.0 vs. 6.9 ± 3.4, respectively; P<0.001). The PSQI scores six months after surgical ASD closure was significantly improved compared to the PSQI score before surgical closure (4.8 ± 2.1 vs. 7.1 ± 2.0, respectively; P<0.001). Total PSQI scores were also statistically different at six months after transcatheter and surgical closure (3.5 ± 2.0 vs. 4.8 ± 2.1, P=0.014). However, six months after both transcatheter and surgical closure, PSQI scores were significantly decreased in both groups which was more pronounced in patients who underwent transcatheter closure. Conclusion: Transcatheter or surgical closure of the defect may be beneficial in improving the sleep quality of adult patients with ASD. Delayed improvement of sleep quality after surgical closure may be an important advantage for transcatheter closure.

Infant Barlow's Disease in Association with Atrial Septal Defect

ABSTRACT Clinical data: Female, seven years old, referred to our service complaining about congestive heart failure symptoms due to mitral valve regurgitation and atrial septal defect. Technical description: Echocardiographic findings compatible with Barlow's disease and atrial septal defect, ostium secundum type. Operation: She was submitted to mitral valvuloplasty with chordal shortening and prosthetic posterior ring (Gregori-Braile®) along with patch atrioseptoplasty. Comments: Mitral valve regurgitation is a rare congenital heart disease and Barlow's disease is probably rarer. Mitral valve repair is the treatment of choice.

Migraña poscierre percutáneo de defectos septales auriculares / Migraine after percutaneous closure of atrial septal defects / Enxaqueca após fechamento percutâneo de comunicação interatrial

La migraña es una enfermedad que se ha visto asociada a defectos septales auriculares y a su cierre percutáneo, estipulándose en la literatura que sería una rara complicación, pero la evidencia al respecto es escasa. Se realizó una revisión narrativa sobre definiciones, epidemiología, fisiopatología y tratamiento de la migraña y de la entidad migraña poscierre percutáneo de defectos del septum auricular, incluyendo trabajos observacionales (retrospectivos, prospectivos), estudios randomizados, reportes de casos, artículos de revisión y metaanálisis existentes en PubMed y Cochrane, para aportar al conocimiento de esta entidad.

Migraine is a disease that has been associated with atrial septal defects and its percutaneous closure, stipulating in the literature that it would be a rare complication, but evidence is scarce. A narrative review was conducted on definitions, epidemiology, pathophysiology and treatment of migraine and the migraine entity after percutaneous closure of atrial septum defects, including observational studies (retrospective, prospective), randomized studies, case reports, review articles and meta-analyses existing in PubMed and Cochrane, to contribute to the knowledge of this entity.

A enxaqueca é uma doença que tem sido associada a defeitos do septo atrial e seu fechamento percutâneo, estipulando na literatura que seria uma complicação rara, mas as evidências são escassas. Foi realizada uma revisão narrativa sobre definições, epidemiologia, fisiopatologia e tratamento da enxaqueca e da entidade migranosa após fechamento percutâneo de defeitos do septo atrial, incluindo estudos observacionais (retrospectivos, prospectivos), estudos randomizados, relatos de caso, artigos de revisão e metanálises existentes no PubMed e Cochrane, para contribuir com o conhecimento dessa entidade.
