Severe Pulmonary Hypertension Secondary to Concomitant Mitral Stenosis with Veno-occlusive Disease in the Context of Systemic Sclerosis: Importance of Careful and Comprehensive Assessment

Pulmonary Arterial Hypertension (PAH) is a clinical syndrome consisting of physiologic/ hemodynamic criteria that are a consequence of several etiologies. Confirmation of pulmonary hypertension is based on right heart catheterization. Pulmonary hypertension is a devastating condition that can lead to considerable morbidity and premature mortality. In the last few decades, significant advancement in the pharmacotherapy of pulmonary hypertension has resulted from better understanding of the complex pathogenesis and pathophysiology of this dreaded disease. Despite these accomplishments, pharmacotherapy of pulmonary hypertension is still far from perfect, and the mortality in this modern treatment era is still unacceptably high. We report a complex clinical presentation characterized by severe pulmonary hypertension secondary to concomitant mitral stenosis with veno-occlusive disease in the context of systemic sclerosis. Our case highlights the importance of a systematic and comprehensive diagnostic approach to avoid missing an underlying pathology.

Case of rheumatic heart disease and severe mitral stenosis, managed by balloon mitral valvuloplasty in pregnancy

Mitral stenosis (MS) is a progressive situation caused by obstruction of blood flow across the mitral valve from the left atrium to the left ventricle. It is one of the most common valvular heart lesions found during pregnancy. The chances of significant maternal and fetal morbidity and mortality are more in the case of severe MS. Balloon mitral valvuloplasty (BMV) is a life-saving procedure in pregnancy instead of surgical correction. We are presenting the case of a 24-week pregnant woman with severe MS. She developed pulmonary edema and had undergone successful BMV which allowed her to tolerate her pregnancy decently. It leads to a decrease in the left atrial pressure as well as pulmonary arterial pressure. The patient underwent normal delivery uneventfully. Antibiotics were used with proper consultation and the patient was treated conservatively with excellent maternal and fetal outcomes. BMV is turns out to be a life-saving therapy for severe MS complicated by pulmonary edema.

Research progress of surgical treatment without valve replacement for rheumatic mitral stenosis / 中国胸心血管外科临床杂志

@#Rheumatic mitral stenosis is one of the most common cardiac valvulopathies in our country, which is relatively rare in European and American countries. Medical therapy is reserved mainly for the treatment of complications, which can not fundamentally change the valve structure. Only surgical treatments can correct these valve lesions, including closed mitral commissurotomy, percutaneous balloon mitral valvuloplasty, mitral valve repair under direct vision and mitral valve replacement. Numerous studies demonstrate that valve repair provides better long-term results, though it occupies a low proportion clinically. This article reviewed domestic and foreign literature concerning surgical treatments for patients with rheumatic mitral stenosis to provide some reference for the peers.

Gender differences in genotypic distribution of endothelin-1 gene and endothelin receptor A gene in pulmonary hypertension associated with rheumatic mitral valve disease

Introduction: The female gender is a risk factor for idiopathic pulmonary arterial hypertension. However, it is unknown whether females with rheumatic mitral valve disease are more predisposed to develop pulmonary hypertension compared to males. Aim: We aimed to investigate whether there was a difference in genotypic distribution of endothelin-1 (ET-1) and endothelin receptor A (ETA) genes between female and male patients of pulmonary hypertension associated with rheumatic mitral valve disease (PH-MVD). Methods: We compared prevalence of ET-1 gene (Lys198Asn) and ETA gene (His323His) polymorphisms according to gender in 123 PH-MVD subjects and 123 healthy controls. Results: The presence of mutant Asn/Asn and either mutant Asn/Asn or heterozygous Lys/Asn genotypes of Lys198Asn polymorphism when compared to Lys/Lys in females showed significant association with higher risk (odds ratio [OR] 4.5; p ¼0.007 and OR 2.39; p ¼0.02, respectively). The presence of heterozygous C/T and either mutant T/T or heterozygous C/T genotypes of His323His polymorphism when compared to wild C/C genotype in females showed a significant association with higher risk (OR 1.96; p ¼0.047 and OR 2.26; p ¼0.01, respectively). No significant difference was seen in genotypic frequencies in males between PH-MVD subjects and controls. Logistic regression analysis showed that mutant genotype Asn/Asn (p ¼0.007) and heterozygous genotype Lys/Asn of Lys198Asn polymorphism (p ¼0.018) were independent predictors of development of PH in females.

Supramitral Membrane with Left Atrial Appendage Thrombus: A Rare Entity

A 4?year?old child with supramitralmembrane (SMM) causing severemitral stenosis (MS) was taken for excision of themembrane. Intraoperative transesophageal echocardiography showed a large thrombus in the left atrial appendage (LAA) in addition to SMM.The case underscores the importance of this extremely rare association and prompt therapy to prevent catastrophic consequences.

Prevalence and Echocardiographic Predictors of Left Atrial Appendage Inactivity in Patients of Mitral Stenosis

Background: Mitral stenosis (MS) is a common valvular heart disease. Thromboembolism is one of the most serious consequences of mitral stenosis, particularly when it is accompanied with atrial fibrillation (AF). When linked with Left atrial appendage inactivity (LAAI), patients with sinus rhythm (SR) are also at risk for this condition. In mitral stenosis, LAA inactivity determined by S-wave is an independent predictor of thromboembolism. The aim of the study was to evaluate the Prevalence and Echocardiographic Predictors of Left Atrial Appendage inactivity in patients of Mitral Stenosis.Material & Methods:Sixty MS patients were evaluated by transthoracic echocardiography (TTE) and all patients underwent transesophageal echocardiography (TEE). The annular systolic (S-wave) and diastolic (Em- and Am-waves) velocities were recorded by tissue Doppler imaging (TDI). LAA inactivity was defined as LAA emptying velocity <25 cm/second determined by pulse wave Doppler at the junction of LA & LAA (TEE). Patients were divided into three groups; group A I (n = 18). Sinus rhythm (SR) and LAA emptying velocity ?25 cm/sec, group A II (n -22): SR and LAA emptying velocity <25cm/sec and group B (n = 20): atrial fibrillation.Results:Thrombus was detected in 14 patients and spontaneous echo contrast (SEC) was detected in 43 patients. Both S-wave and peak LAA emptying velocities were decreasing, while SEC frequency and density were increasing from group A to group B. There was a positive correlation between LAA emptying vs. S-wave and LAA emptying vs. Am velocities (p < 0.001, r= 0.708 and p<0.001, r=0.495). Multivariate regression analysis showed that only S-wave is the independent predictor of inactive LAA (p = 0.001, odds ratio = 0.133, 95% Cl =0.032-0.556). In patients with SR, the cutoff value of S-wave was 10 cm/sec for the prediction of the presence of inactive LAA (sensitivity: 92.3%, specificity: 95.3%).Conclusions:In individuals with severe mitral stenosis in sinus rhythm, there is a significant prevalence of left atrial appendage inactivity. The mean pressure gradient across the mitral valve, as well as S-wave are independent predictors of left atrial appendage inactivity. Inactivity of the left atrial appendage is an independent predictor of left atrial/left atrial appendage smoke and associated thrombus.

Association of level of IL-6, IL-10, IL-18, tumour necrosis factor-?with rheumatic mitral stenosis and subsequent pulmonary hypertension

Background:Objective of the study was to provide insight on the immune response in patients of rheumatic heart disease, mitral stenosis and evaluation of various cytokines in pulmonary hypertension secondary to rheumatic heart disease.Methods:Total 163 subjects, more than 18 year of age, were enrolled in this study. 84 subjects with rheumatic mitral stenosis (group A) diagnosed on two-dimensional echocardiography (2D echo)and 79 normal healthy volunteers(group B). Patients with mitral stenosis were further divided into subgroups based on severity of mitral stenosis [mitral valve area (MVA >1 cm2 and MVA <1 cm2)(subgroup Aa and Ab)]and presence or absence of pulmonary hypertension [pulmonary arterial systolic pressure (PASP >36 mm Hg)(subgroup Ac and Ad)]. Interleukins IL-6, IL-10, IL-18, tumour necrosis factor alpha (TNF-?)andhigh-sensitivity C-reactive protein (hs-CRP)levels were assessed in both groups.Results:Mean IL-6, IL-10, IL-18, TNF-? and hs-CRP in group A and group B was 6.57�53 and 2.73�p?0.001), 8.185�8 and 3.51�86(p?0.001), 136.31�.0 and 47.96�76(p?0.001), 21.26�.59 and 5.36�57(p?0.001), 4.69�3 and 2.63�22(p?0.008) respectively. On subgroup analysis mean TNF-? in subgroup Aa was 20.71�.84, while in subgroup Ab was 7.56�93 (p?0.001). Mean IL-10 in subgroup Ac and Ad was 8.74�29 and 7.47�82, respectively. Differences in levels of other cytokines in these subgroups were not found statistically significant.Conclusions:This study finds increased IL-6, IL-10, IL-18, TNF-? and hs-CRP levels in subjects with rheumatic mitral stenosis. Subjects with severe mitral stenosis had increased TNF-? levels. Subjects of mitral stenosis having pulmonary hypertension had increased IL-10 levels.

Left atrial function by two-dimensional speckle tracking echocardiography in patients with severe rheumatic mitral stenosis and pulmonary hypertension

We studied left atrial (LA) function in severe rheumatic mitral stenosis (MS) patients using twodimensional speckle tracking echocardiography (STE). Eighty patients with isolated severe MS in sinus rhythm and 40 controls underwent comprehensive echocardiography including STE derived LA strain [reservoir strain (LASr), conduit strain (LAScd) and contractile strain (LASct)]. The mean MVA was 0.93 ± 0.21 cm2 . The mean values of LASr (14.73 ± 8.59%), LAScd (±7.61 ± 4.47%) and LASct (±7.16 ± 5.15%) in patients were significantly lower (p < 0.001) vs. controls 44.11 ± 10.44%, ±32.45 ± 7.63%, -11.85 ± 6.77% respectively and showed decreasing trend with increasing MS severity and higher NYHA class. In conclusion, LA dysfunction is prevalent in severe MS irrespective of NYHA functional class.

Manejo de la estenosis mitral durante el embarazo / Management of mitral stenosis during pregnancy

Las cardiopatías complican alrededor del 4 por ciento de los embarazos; y representan la principal causa no obstétrica de muerte materna. Las lesiones valvulares tienen una alta prevalencia, siendo la estenosis mitral la de peor pronóstico durante el embarazo. El presente artículo tiene como objetivo exponer las recomendaciones del Servicio Nacional de Cardiopatía y Embarazo para el manejo de la estenosis mitral durante la gestación. Resulta crucial la evaluación de la anatomía valvular y la severidad de la enfermedad. Lesiones moderadas a severas deben ser tratadas con betabloqueadores cardioselectivos y comisurotomía percutánea electiva, si la anatomía es favorable. Si hay retención de volumen están indicados los diuréticos. Entre las drogas de uso obstétrico están contraindicadas las prostaglandinas, el nifedipino y el fenoterol. El momento de terminación del embarazo depende de la edad gestacional y de la aparición de signos de descompensación materna o fetal, en cuyo caso tienen indicación de cesárea(AU)

Heart disease complicates about 4 percent of pregnancies; and represent the leading non-obstetric cause of maternal death. Valvular lesions have a high prevalence, being mitral stenosis the one with the worst prognosis during pregnancy. This article aims to present the recommendations of the National Heart Disease and Pregnancy Service for the management of mitral stenosis during pregnancy. Evaluation of valve anatomy and disease severity is crucial. Moderate to severe injuries should be treated with cardioselective beta-blockers and elective percutaneous commissurotomy, if the anatomy is favorable. If there is volume retention, diuretics are indicated. Among the drugs for obstetric use, prostaglandins, nifedipine and fenoterol are contraindicated. The time of termination of pregnancy depends on the gestational age and the appearance of signs of maternal or fetal decompensation, in which case they have an indication for cesarean section(AU)

Estenosis mitral con calcificación severa del anillo mitral: reemplazo mitral con prótesis OnX Conform en posición supraanular / Mitral stenosis with severe annular calcification: mitral valve replacement with an OnX Conform prosthesis in a supra annular position

Abstract A 68-year-old man previously subjected to radiotherapy had a prior aortic valve replacement due de radiation induced calcification of the aortic valve. Presently the patient developed severe calcification of the mitral valve ring leading to critical mitral valve stenosis. A supra annular implantation of an On X Conform valve was successfully achieved. The clinical course was uneventful, and the echocardiographic evaluation demonstrated a normal function of the valve. Different alternatives for the surgical management of this complication are discussed.

​A Comparative Study of Changes in Left Ventricular Function after Mitral Valve Replacement in Patients with Severe Rheumatic Mitral Regurgitation with and without Mild Mitral Stenosis

Introduction: Presently off- pump CABG has proved itself tobe a safe, cheaper and effective alternative of on- pump CABG.However, it requires manipulation, displacement, positioning& mechanical stabilization of the heart during grafting whichmay cause haemodynamic alteration. Study was done withthe objective of finding out the changes in Central VenousPressure (CVP); Mean Arterial Pressure (MAP); MeanPulmonary Arterial Pressure (MPAP); Right Ventricular EndDiastolic Pressure (RVEDP) & Left Ventricular End DiastolicPressure (LVEDP) while grafting the anterior, lateral &inferior surfaces of heart during off-pump CABG.Material and methods: Over one year time, 50 patients withLVEF ≥40%, undergoing off-pump CABG were monitoredfor the above parameters at various stages of their operation,namely:- 1. During manipulation & shunt introduction,2.During anastomosis without shunt, 3.During anastomosiswith shunt & 4.After anastomosis; while grafting the anterior,lateral & inferior surfaces of heart. These results werecompared with the baseline values of CVP, MAP, MPAP,RVEDP & LVEDP, to look for statistical significance.Results: During manipulation & shunt introduction; CVP(mmHg) significantly increased during Ramus grafting - 12±1.8(p<0.047); and also during OM grafting – 12.6±1.9 (p<0.045),when compared to a baseline value of 9±1.8. The MAP(mmHg) was significantly decreased during manipulation &shunt introduction in Diagonals - 70±5.8 (p<0.046), Ramus- 70±5.8 (p<0.048), OMs - 65±5.8 (p<0.028) & in the Rightterritory - 69±5.9 (p<0.032); as compared with baselineMAP of 76±11.7. During anastomosis without shunt also, theMAP(mmHg) significantly decreased while grafting LAD- 70±3.8 (p<0.048), Diagonals - 68±3.8 (p<0.039), OMs –71.8±4.8 (p<0.039) & Right sided arteries 70.8±4.6 (p<0.039),as compared with baseline MAP values. The MPAP(mmHg)was significantly increased – 18.3±3.7 (p<0.047) as comparedto the baseline value of 16±2.4 during manipulation & shuntintroduction in the OMs.Conclusion: During OPCABG there will be significantalterations in haemodynamics mostly due to mobilizationof the heart, which is necessary to visualise the targetvessels properly & stabilisation of the concerned areawith stabiliser. However, by observing the haemodynamicvariations constantly & by making necessary mechanical &pharmacological adjustments, unnecessary conversion to Onpump technique can be avoided.

Quality of life assessment after successful percutaneous transmitral commissurotomy and ascertain its relationship with gender / Evaluación de la calidad de vida tras comisurotomía mitral percutánea exitosa y determinación de su relación con el sexo

Abstract Background: percutaneous transmitral commissurotomy has become an ideal treatment option for mitral stenosis due to its less adverse events and more favorable outcomes. Patients improve symptomatically after percutaneous transmitral commissurotomy but we have minimal available data about the quality of life after percutaneous transmitral commissurotomy. Objective: to assess the quality of life after percutaneous transmitral commissurotomy through WHOQol scoring covering different aspects of life, to determine its correlation with a net gain in mitral valve area (MVA) and to ascertain its association with gender. Methods: it was a prospective cohort study carried out for a period of 15 months. A total of 100 patients with mitral stenosis who had successful percutaneous transmitral commissurotomy done were enrolled in the study. Among the total included, 4 patients were lost to follow up and data were collected from 96 patients. Quality of life was assessed before the procedure, at 1 month and 3 months follow up after percutaneous transmitral commissurotomy using WHOQol scoring questionnaire. Results: among 96 patients, 64 (67%) were females and 32 (33%) were males. WHOQol scoring improved significantly after percutaneous transmitral commissurotomy from 32.8±8.9 to 54.6±11.2 and 62.8± 9.7, after one month and 3 months respectively. There was a significant association between net gain of MVA and WHOQol scoring with an R value of 0.46 and p value of 0.03. There was no difference in group comparison of all the six domains between male and female patients. Conclusion: successful percutaneous transmitral commissurotomy improves the quality of life in mitral stenosis patients regardless of their gender and has a positive correlation with a net gain in mitral valve area.

Resumen Antecedentes: La comisurotomía mitral percutánea se ha convertido en una opción terapéutica ideal para la estenosis mitral, debido a efectos menos adversos y a resultados más favorables. Los pacientes mejoran sintomáticamente tras la realización de esta técnica, aunque se dispone de escasos datos acerca de la calidad de vida tras su puesta en práctica. Objetivo: Evaluar la calidad de vida tras la comisurotomía mitral percutánea mediante la puntuación WHOQol, que cubre diferentes aspectos de la vida, para determinar su correlación con la ganancia neta del área valvular mitral (AVM), y determinar su asociación con el sexo. Métodos: Estudio prospectivo de cohorte durante un periodo de 15 meses, en el que se incluyeron 100 pacientes con estenosis mitral a quienes se les practicó con éxito comisurotomía mitral percutánea. De entre el total incluido, se perdieron 4 pacientes durante el estudio, por lo que se recolectaron datos de los 96 pacientes restantes. La calidad de vida se evaluó antes del procedimiento, y transcurridos un mes y tres meses de seguimiento, utilizando el cuestionario de puntuación WHOQol. Resultados: De los 96 pacientes, 64 (67%) eran mujeres y 32 (33%) varones. La puntuación WHOQol mejoró considerablemente tras la realización de la comisurotomía mitral percutánea, con valores de 32,8±8,9 a 54,6±11,2 y 62,8± 9,7, transcurridos uno y 3 meses, respectivamente. Se produjo una asociación significativa entre la ganancia neta de AVM y la puntuación WHOQol, con un valor R de 0,46 y un valor p de 0,03. No se produjo diferencia alguna en cuanto a la comparación grupal de los seis dominios entre varones y mujeres. Conclusión: La comisurotomía mitral percutánea exitosa mejora la calidad de vida de los pacientes de estenosis mitral, independientemente del sexo, y tiene una correlación positiva con la ganancia neta del área valvular mitral.

Percutaneous Balloon Mitral Valvotomy and Percutaneous Coronary Intervention of Left Anterior Descending Artery in Combined Procedure

In countries like India rheumatic heart disease (RHD) is still a common problem, and with improvements in diagnosis and treatment, the lifespan of these patients is increased. With increase in the lifespan, these patients may develop coronary artery disease (CAD) and present as acute coronary syndrome (ACS). In some cases especially RHD with severe mitral stenosis (MS), thrombus that develop in left atrium may embolize in one of the coronary arteries, leading to acute coronary syndrome. We report a case of 51 year old female who was a known case of rheumatic heart disease and now presented with acute coronary syndrome. Patient was hemodynamically unstable and underwent percutaneous balloon mitral valvotomy (PBMV) and percutaneous coronary intervention (PCI) simultaneously. We here discuss the possible complications that need to be addressed in such scenario and how can we approach such cases. This is first of such intervention at our institute and also there are very few such records available online. Patient tolerated the procedure well with significant clinical improvement.

Role of perioperative echocardiography in repair of incomplete shone complex: A case series

Multilevel obstruction of left-sided heart structures was originally characterized by Shone et al. The formulation of an appropriate operative strategy remains challenging and needs to be individualized for this complex subset of patients. Intraoperative transesophageal echocardiography (TEE) not only helps in delineating spatial anatomy but also reveals associated anomalies that help in decision-making regarding operative strategies for these patients. Here, we discuss five such cases of Shone's anomaly presenting at varied age group with different associated anomaly in which intraoperative TEE played a pivotal role in the management.

Prophylactic Use of Magnesium Sulphate to Prevent Arrythmias in Patients with Rheumatic Heart Disease Undergoing Closed Mitral Valvotomy

Maintenance of sinus rhythm is superior to incidence of atrial fibrillation (AF) in patients with rheumatic heartdisease undergoing Closed Mitral Valvotomy (CMV). The present study was done to evaluate the effect ofprophylactic use of Magnesium Sulphate (MgSo4), intravenously (i.v) soon after opening the stenosed MitralValve using Tubbs dilators by Surgeon, in patients undergoing CMV. One hundred and twenty patients withMitral Stenosis (MS) (mitral valve area < 1cm2), normal mitral valvular apparatus, no mitral regurgitation,mitral score not more than 7/16 planned for CMV. These patients were divided in two groups of 60 each.Group (I) (n=60) received. MgSo4, 30 mg/kg diluted to 20 ml with normal saline soon after mitral valvotomyand Group - II (n=60) received 20 ml of normal saline. The standardized protocol for CMV was maintainedfor all the patients. Before surgery AF was observed in 56.67% of patients in group I and 48.33% of patientsin group II (p=0.46). Postoperatively in ICU, 30% of patients in group I and 70% of patients in group II hadAF(p<0.0001). A single prophylactic intra operative dose of i.v MgSO4 decreased post valvotomy arrhythmiain comparision to placebo group . Thus, a single dose of intraoperative MgSO4 can be used to decreasepostoperative arrhythmias in patients of M.S undergoing CMV

Epidural Anaesthesia a Saviour in a Case of Mitral Stenosis Posted For Emergency LSCS

It is challenging for an Anaesthesiologist to provide correct anaesthesia technique to a patient with Mitral Stenosis posted for Emergency LSCS. In the presence of maternal heart disease, the circulatory changes of pregnancy may result in exacerbation of the hemodynamic changes leading to maternal and fetal morbididty and mortality. We report the successful anaesthetic management with graded epidural technique which minimises the hemodyanamic perturbations. Successful management requires proper perioperative monitoring and thorough knowledge of the valvular heart disease.

Sudden appearance of new clot

A patient having mitral stenosis with chronic atrial fibrillation, large left atrium, and spontaneous echo contrast is expected to have clot in LA or LAA. TEE is more sensitive to detect thrombus in LA and LAA than transthoracic echocardiography. However, false-negative results can still occur due to multilobed LAA, and a thrombus can be potentially missed.

A study to assess valvular heart disease in a tertiary care hospital: a single centre finding

Background: Diseases of the heart valves constitute a major cause of cardiovascular morbidity and mortality worldwide with an enormous burden on healthcare resources. The present study was undertaken to study incidence and demography of valvular heart disease, to assess echocardiography and colour doppler findings of patients with valvular heart disease and to find out complications in patients with valvular heart disease.Methods: A hospital based longitudinal case study was undertaken at medicine department of Dr. V.M. Government Medical College, Solapur, Maharashtra, India for a period of two years. One hundred and twenty-four (124) patients attending OPD participated in the study.Results: In the present study, out of 124 patients, mitral valve was most commonly involved, 105(84.67%) and the least common involved was tricuspid 1(0.81%). The most common aetiology was rheumatic origin 75(94.94%). In the present study the most common complication was pulmonary hypertension 69(55.65%), followed by congestive cardiac failure (33.87%), acute pulmonary edema (12.09%), infective endocarditis (4.84%), cerebrovascular accident (4.03%), left atrial thrombus (3.23%) and death (3.23%).Conclusions: Multiple valves were affected in more than a third of all cases, although recent research in India continue to demonstrate a declining trend in the prevalence of RHD, rheumatic involvement is still the dominant form of valvular heart disease in India.

Correlation between Mitral Annular Systolic Velocity and Left Atrial Appendage Function in Mitral Stenosis

The left atrial appendage is a long, tubular and trabecular structure and has a narrow junction with the left atrium. The left atrial appendage has been the focus of clinicians’ interests, because it is a potential site for the development of thrombus in several diseases. Aim: To study the correlation between mitral annular systolic velocity and left atrial appendage function in mitral stenosis. Methods: 60 patient with moderate to severe Mitral Stenosis with MVO <1.5 cm2 were included in the study. All eligible patients underwent a detailed history and clinical examination. A 12 lead electrocardiogram was taken. Echocardiographic evaluation was done for all patients Atrial fibrillation diagnosis was based on the electrocardiogram. Result: There was a positive correlation between these two variables which are statistically significant. (r=0.944, p-value<0.001). There was a positive correlation between left atrial appendage emptying velocity and mitral annular late diastolic velocity in patients in sinus rhythm. (r=0.695(p<0.001) The cut off value of peak annulus systolic velocity which is derived from the analysis of the receiver operator characteristic curve is 13.5cm/sec. The area under the curve is 0.840 with confidence interval 0.689 to 0.936 and the p-value<0.001. This value predicts inactive LAA (Laaev<25cm/sec) with a sensitivity of 92% and specificity of 96.5%. Conclusion: The systolic and diastolic annular velocities obtained by Doppler tissue imaging are reduced in patients with mitral stenosis. There is a positive correlation between annular systolic and left atrial appendage emptying velocities in mitral stenosis. The annular systolic velocity is an independent predictor for the presence of inactive left atrial appendage in mitral stenosis patients with sinus rhythm.

Percutaneous mitral balloon valvuloplasty: clinical and echocardiographic factors associated with success in a Tertiary-Care Hospital in Mexico / Valvuloplastía mitral percutánea con balón: factores clínicos y ecocardiográficos asociados con el éxito en un hospital de tercer nivel en México

Abstract: Introduction: Prevalence of mitral stenosis of rheumatic etiology has diminished. However, in Mexico there are some regions where still represents a health issue in productive population. Percutaneous valvuloplasty has become the treatment of choice in those with favorable anatomy. When successful immediate results are obtained, adequate long-term results are predicted. Objective: To determine the clinical and echocardiographic factors associated with the immediate success of percutaneous mitral valvuloplasty. Material and methods: A comparative and retrospective cross-sectional, observational study. Clinical records of patients treated with percutaneous valvuloplasty between 2000-2016 were reviewed. We studied clinical, echocardiographic, and procedural factors associated with immediate success. Descriptive and inferential statistics were used with SPSS v2.4 package. Results: A total of 363 patients. Female gender 287 (79.1%), age 50.8 ± 10.9 years. Functional class II 218 (60.1%). Atrial fibrillation 201 (55.4%). Previous procedure 78 (21.5%). Wilkins score 8-10: 228 (62.8%). Previous moderate mitral insufficiency 20 (5.5%). Inoue Balloon used in 343 (94.5%). We achieved success in 309 (85.1%), 26 had complications (7.16%), one death. We observed an increased number of complications in patients with pulmonary hypertension (> 60 mmHg) (p = 0.01), transvalvular gradient (mean > 10 mmHg) (p = 0.049), previous moderate mitral regurgitation (p = 0.001), and procedures with double-balloon (p = 0.001). We identified as unfavorable predictors of the procedure with statistical significance: Wilkins score 8-10 points (OR 2.6, 95% CI, 1.3-5.2) and previous moderate mitral regurgitation (OR 3.3, 95% CI, 1.28-8.93). Conclusion: Similar results were obtained with previous studies (success, complications and mortality). Only the Wilkins score greater than 8 points and the previous moderate mitral regurgitation were unfavorable predictors for the success of the procedure.
