Ongoing assertion of two-dimensional measurements on differentiation type of left ventricular hypertrophy: Focus on inferior vena cava.

BACKGROUND: Left ventricular hypertrophy (LVH), including hypertensive LVH, hypertrophic cardiomyopathy (HCM) and cardiac amyloidosis (CA), is a commonly encountered condition in cardiology practice, presenting challenges in differential diagnosis. In this study, we aimed to investigate the importance of echocardiographic evaluation of the inferior vena cava (IVC) in distinguishing LVH subtypes including hypertensive LVH, HCM, and CA. METHODS: In this retrospective study, patients with common causes of LVH including hypertensive LVH, HCM, and CA were included. The role of echocardiographic evaluation of IVC diameter and collapsibility in distinguishing these causes of LVH was assessed in conjunction with other echocardiographic, clinical, and imaging methods. RESULTS: A total of 211 patients (45% HCM, 43% hypertensive heart disease, and 12% CA) were included in our study. Their mean age was 56.6 years and 62% of them were male. While mean IVC diameter was significantly dilated in CA patients (13.4 mm in hypertensive LVH, 16.0 mm in HCM, and 21.1 mm in CA, p < .001), its collapsibility was reduced (IVC collapsible in 95% of hypertensive patients, 72% of HCM patients, and 12% of CA patients, p < .001). In the analysis of diagnostic probabilities, the presence of both hypovoltage and IVC dilation is significant for CA patients. Although it is not statistically significant, the presence of IVC dilation along with atrial fibrillation supports the diagnosis of HCM. CONCLUSION: In conclusion, although advances in imaging techniques facilitate the diagnosis of LVH, simple echocardiographic methods should never be overlooked. Our study supports the notion that IVC assessment could play an important role in the differential diagnosis of LVH.

The effect of music played to new birth mothers on postpartum blues: A randomized controlled trial.

BACKGROUND: Postpartum blues/postpartum maternal blues is a psychological disorder experienced by mothers with symptoms of postpartum sadness, easy crying, easy anxiety, sensitivity, indecisiveness. The study aimed to examine the effect of music played on newly delivered mothers on postpartum blues. METHODS: A prospective, two-arm, randomized controlled study was conducted on n = 82 (41 = control, 41 = music group) mothers who gave birth at term in Trakya University Health Research and Application Center Maternity Service between May and December 2023. The research data were collected through the Personal Information Form, Stein Blues Scale (SBS), and Edinburgh Postpartum Depression Scale (EPDS). The scales used in the study were evaluated four times: postoperative 0-3 h, 12th, 24th, and 36th hours. RESULTS: The postoperative 0-3 h SBS test median of the new mothers in the music group was 19.00, and the 36th hours test median was 2.00, while the postoperative 0-3 h SBS test median of the control group was 21.00, and the 36th hour test median was 13.00. The postoperative 0-3 h EPDS test median of the new mothers in the music group was 22.00, and the 36th hours test median was 0.00, while the postoperative 0-3 h EPDS test median of the control group was 26.00, and the 36th hours test median was 10.00. A significant difference was found in the 12th, 24th, and 36th hours (p < .001). A statistically significant high positive correlation was found between EPDS and SBS in the 12th, 24th, and 36th hours (p < .001). CONCLUSIONS: In the study, it was found that music played to newly delivered mothers reduced postpartum blues and depression levels. REGISTRATION: The submission date for a clinical trial protocol is prior to completing participant recruitment and for a systematic review, prior to completing full paper screening. NCT06252155.

Turkish Real Life Atrial Fibrillation in Clinical Practice: TRAFFIC Study.

BACKGROUND: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide and is associated with an increased risk of thromboembolism, ischemic stroke, impaired quality of life, and mortality. The latest research that shows the prevalence and incidence of AF patients in Türkiye was the Turkish Adults' Heart Disease and Risk Factors study, which included 3,450 patients and collected data until 2006/07.The Turkish Real Life Atrial Fibrillation in Clinical Practice (TRAFFIC) study is planned to present current prevalence data, reveal the reflection of new treatment and risk approaches in our country, and develop new prediction models in terms of outcomes. METHODS: The TRAFFIC study is a national, prospective, multicenter, observational registry. The study aims to collect data from at least 1900 patients diagnosed with atrial fibrillation, with the participation of 40 centers from Türkiye. The following data will be collected from patients: baseline demographic characteristics, medical history, vital signs, symptoms of AF, ECG and echocardiographic findings, CHADS2-VASC2 and HAS-BLED (1-year risk of major bleeding) risk scores, interventional treatments, antithrombotic and antiarrhythmic medications, or other medications used by the patients. For patients who use warfarin, international normalized ratio levels will be monitored. Follow-up data will be collected at 6, 12, 18, and 24 months. Primary endpoints are defined as systemic embolism or major safety endpoints (major bleeding, clinically relevant nonmajor bleeding, and minor bleeding as defined by the International Society on Thrombosis and Hemostasis). The main secondary endpoints include major adverse cardiovascular events (systemic embolism, myocardial infarction, and cardiovascular death), all-cause mortality, and hospitalizations due to all causes or specific reasons. RESULTS: The results of the 12-month follow-up of the study are planned to be shared by the end of 2023. CONCLUSION: The TRAFFIC study will reveal the prevalence and incidence, demographic characteristics, and risk profiles of AF patients in Türkiye. Additionally, it will provide insights into how current treatments are reflected in this population. Furthermore, risk prediction modeling and risk scoring can be conducted for patients with AF.

Transcatheter Closure or Surgery for Symptomatic Paravalvular Leaks: The Multicenter KISS Registry.

BACKGROUND: The optimal treatment of symptomatic paravalvular leak (PVL) remains controversial between transcatheter closure (TC) and surgery. This large-scale study aimed to retrospectively evaluate the long-term outcomes of the patients who underwent reoperation or TC of PVLs. METHODS AND RESULTS: A total of 335 (men, 209 [62.4%]; mean age, 58.15±12.77 years) patients who underwent treatment of PVL at 3 tertiary centers between January 2002 and December 2021 were included. Echocardiographic features, procedure details, and in-hospital or long-term outcomes were assessed. The primary end point was defined as the all-cause death during follow-up. The regression models were adjusted by applying the inverse probability weighted approach to reduce treatment selection bias. The initial management strategy was TC in 171 (51%) patients and surgery in 164 (49%) cases. Three hundred cases (89.6%) had mitral PVL, and 35 (10.4%) had aortic PVL. The mean left ventricular ejection fraction was 52.03±10.79%. Technical (78.9 versus 76.2%; P=0.549) and procedural success (73.7 versus 65.2%; P=0.093) were similar between both groups. In both univariate and multivariable logistic regression analysis, the in-hospital mortality rate in the overall population was significantly higher (15.9 versus 4.7%) in the surgery group compared with the TC group (unadjusted odds ratio, 3.13 [95% CI, 1.75-5.88]; P=0.001; and adjusted odds ratio (inverse probability-weighted), 4.55 [95% CI, 2.27-10.0]; P<0.001). However, the long-term mortality rate in the overall population did not differ between the surgery group and the TC group (unadjusted hazard ratio [HR], 0.86 [95% CI, 0.59-1.25]; P=0.435; and adjusted HR (inverse probability-weighted), 1.11 [95% CI, 0.67-1.81]; P=0.679). CONCLUSIONS: The current data suggest that percutaneous closure of PVL was associated with lower early and comparable long-term mortality rates compared with surgery.

Impact of Bileaflet Mechanical Mitral Valve Orientation on Pannus Overgrowth.

OBJECTIVE: Pannus overgrowth is a chronic inflammatory process that can cause valve dysfunction and threaten the durability of prosthetic valves. Bileaflet mechanical mitral valve can be implanted in either an anatomical (parallel to the anatomical axis) or nonanatomical (perpendicular or oblique to the anatomical axis) orientation. The effect of the rotational orientation of the bileaflet mechanical mitral valve on excessive pannus enlargement is unknown. The present study compared the effect of bileaflet mechanical mitral valve orientation on pannus overgrowth. METHODS: The study included patients who underwent bileaflet mechanical mitral valve replacement for rheumatic mitral valve stenosis. The pannus formation was confirmed by reexamining all transesophageal echocardiography images in the picture archiving and communication systems between May 2017 and April 2021. The primary aim of this study was the development of pannus overgrowth. Patients were divided into 2 groups based on their implantation orientation of the bileaflet mechanical mitral valve. RESULTS: Pannus overgrowth was found in 26 patients (56.5%) in the anatomical orientation group and 71 patients (74.7%) in the nonanatomical orientation group (P = 0.03). Anatomical orientation reduced the development of pannus overgrowth (odds ratio [OR] = 0.39, P = 0.04), and double left heart valve replacement increased the development of pannus overgrowth (OR = 2.73, P = 0.04). CONCLUSIONS: Pannus overgrowth was less common in bileaflet mechanical mitral valves implanted in the anatomical orientation.

The relation of right ventricular outflow tract measurements with in-hospital clinical outcomes after tricuspid valve surgery.

Right ventricular (RV) function is a determining factor for clinical outcomes in patients undergoing tricuspid valve surgery (TVS). Our aim was to investigate the importance of the function of the right ventricular outflow tract (RVOT), which is an important anatomical region of the RV, in patients underwent TVS. 104 patients who underwent TVS were analyzed retrospectively. Patients with previous cardiac surgery, congenital heart disease, or heart failure were excluded. The parasternal short-axis view at the level of the aortic root was used to measure RVOT dimensions and RVOT fractional shortening (RVOT-FS). The effect of RVOT diameter and function on major adverse cardiac events (MACE) after TVS was investigated. In our study, MACE, consisting of pacemaker implantation, acute kidney injury, postoperative atrial fibrillation and mortality, was developed at 44 (42.3%) patients.We compared the predictive performances of RVOT end-systolic (RVOTs) diameter, RVOT end-diastolic (RVOTd) diameter, RVOT-FS and RV diameters in prediction of MACE. The model including the RVOTs had higher AUC, R2 and likelihood ratio X2 values (0.775, 0.287 and 25.0, respectively) than RVOTd (0.770, 0.279 and 24.2, respectively) and RVOT-FS (0.750, 0.215 and 18.1, respectively). RVOT diameters showed better performance in predicting MACE than RV diameters. Moreover, there was statistically significant association between RVOTs, RVOTd and MACE (p value were 0.014 and 0.027, respectively), while no association between RVOT-FS and MACE (p value was 0.177). In summary, we determined that the RVOT diameters are important predictors for the in-hospital clinical outcomes of patients who underwent TVS.

Influence of cardiac biomarkers on predicting significant coronary artery disease in hypertrophic cardiomyopathy patients.

BACKGROUND: In this study, our aim was to investigate the role of cardiac biomarkers in predicting the presence of significant coronary artery disease in hypertrophic cardiomyopathy (HCM) patients. METHODS: The study population was composed of hypertrophic cardiomyopathy patients who underwent coronary angiography at a single center between June 2021 and March 2023, and whose cardiac biomarkers were evaluated before the procedure. HCM patients were screened retrospectively. Significant CAD was defined as > 50% stenosis of the left main coronary artery or > 70% stenosis in a major coronary vessel. Demographic, echocardiographic and cardiac biomarker values were compared between the two groups. RESULTS: A total of 123 patients were evaluated. Significant CAD was detected in 39 (31.7%) patients. Patients with significant CAD had higher CK-MB values than those without CAD [2.8 (2.1-4.0) vs. 3.4 (2.8-4.6), p = 0.036], and a higher level of high-sensitivity troponin T (hs-TnT) than those without CAD (24 vs. 17.8, p = 0.022). the NT-proBNP/hs-TnT ratio was found to be significantly lower in patients with CAD than in those with CAD (31.4 vs. 21.4, p = 0.019). In multivariate anaylsis, NT-proBNP/hs-TnT was determined as an independent predictor for significant CAD. In ROC analysis, NT-proBNP/hs-TnT ratio lower than the cut-off value of 30.7 could detect the presence of significant CAD with 76.9% sensitivity and 53.6% specificity (AUC: 0.632, 95% CI: 0.528-0.736, p = 0.019). CONCLUSION: To sum up, we suggest that cardiac biomarkers were valuable and simple parameters in terms of significant CAD in HCM patients.

Contribution of Three-Dimensional Echocardiography Xplane Mode in the Evaluation of Semilunar Cusps: Two Different Case Reports.

Orthogonal-biplane imaging (X-plane) is relatively a new tooL and provides comprehensive information about mitral valve and left atrial appendage evaluation. On the other hand, X-plane method is a promising method in the diagnosis of semilunar valve pathologies. Below, we report 2 cases, in which X-plane method was used, in order to clarify diagnosis. Case 1: Case 1 was a 63-year-old male patient who was admitted to our clinic with dyspnea. Right ventricular dilatation and hypertrophy were assessed. In order to determine the exact reason for right ventricular pressure overload, the pulmonary valve was evaluated by X-plane, and a bicuspid pulmonary valve was represented. This patient underwent pulmonary valve percutaneous valvuloplasty. Case 2: Case 2 was a 48-year-old male patient who was admitted to our hospital with a history of cerebrovascular event. His initial transthoracic and transesophageal echocardiography showed a hyperechoic mobile mass on the non-coronary cusp. However, after X-plane was used to detect the aortic valve, it was the prolapsed part of the non-coronary cusp adjacent to the commissure. These 2 case reports demonstrated the efficacy of the X-plane method in the diagnosis of semilunar valve pathologies in daily practice.

Bioprosthetic aortic valve thrombosis under effective direct oral anticoagulant therapy.

With the increase in transcatheter procedures, the use of bioprosthetic valves has become more frequent in clinical practice. However, the optimal antithrombotic management of patients with bioprosthetic valves remains controversial. In this case report, we describe a patient with a bioprosthetic aortic valve who developed a thrombus while receiving effective dose direct oral anticoagulant (DOAC) therapy. A 73-year-old male patient with a bioprosthetic aortic valve replacement 2 years prior presented with a mobile thrombus and early degeneration of the valve, detected during routine follow-up while being treated with apixaban. Although the valve thrombus regressed after switching to a different anticoagulant drug, we observed that the decreased but still high gradient persisted due to the early degeneration. Anticoagulant management of bioprosthetic valve patients demands careful attention. Although evidence supporting the use of DOACs is growing, close patient follow-up and further evaluation in case of doubt remain critical. The development of a thrombus in a bioprosthetic valve patient who is receiving anticoagulation therapy, as in this case, highlights the need for optimal management to prevent thromboembolic complications and valve degeneration.

Relationship between myocardial bridging and fatal ventricular arrhythmias in patients with hypertrophic cardiomyopathy: the HCM-MB study.

BACKGROUND: Myocardial bridging (MB) and hypertrophic cardiomyopathy (HCM) are associated with the risk of fatal ventricular arrhythmias (VAs). The goal of the study was to determine the relationship between MB and fatal VAs in HCM patients with implantable cardiac defibrillators (ICD). METHODS: A total of 108 HCM patients (mean age: 46.6 ± 13.6 years; male: 73) were enrolled in this retrospective study. All patients underwent transthoracic echocardiography and coronary computed tomography angiography. Fatal VAs including sustained ventricular tachycardia and ventricular fibrillation were documented in ICD records. RESULTS: There were documented fatal VAs in 29 (26.8%) patients during a mean follow-up time of 71.3 ± 30.9 months. Compared with the other groups, the fatal VA group had a higher incidence of the following: presence of MB (82.8 vs. 38%, p < 0.001), deep MB (62.1 vs. 6.3%, p < 0.001), very deep MB (24.1 vs. 0%, p < 0.001), long MB (65.5 vs. 11.4%, p < 0.001), presence of > 1 MB (17.2 vs. 0%, p = 0.001), and MB of the left anterior descending artery (79.3 vs. 17.7%, p < 0.001) . Sudden cardiac death (SCD) risk score (hazard ratio: 1.194; 95% CI: 1.071-1.330; p = 0.001) and presence of MB (hazard ratio: 3.815; 95% CI: 1.41-10.284; p = 0.008) were found to be independent predictors of fatal VAs in HCM patients. CONCLUSIONS: The current data suggest that the SCD risk score and presence of MB were independent risk factors for fatal VAs in patients with HCM. In addition to conventional risk factors, the coronary anatomical course can provide clinicians with valuable information when assessing the risk of fatal VAs in HCM patients.

The association of left atrial mechanics with left ventricular morphology in patients with hypertrophic cardiomyopathy: a cardiac magnetic resonance study.

Purpose: Hypertrophic cardiomyopathy (HCM) is related with structural and pathologic changes in the left atrium (LA) and left ventricle (LV). The aim of this study was to explore the association between LA mechanics and LV characteristics in patients with HCM using cardiac magnetic resonance feature tracking (CMR-FT). Material and methods: A total of 76 patients with HCM and 26 healthy controls were included in the study. The parameters including the extent of LV late gadolinium enhancement (LGE-%) and the LV early diastolic longitudinal strain rate (edLSR) were assessed for LV. LA conduit, booster, and reservoir functions were assessed by LA fractional volumes and strain analyses using CMR-FT. HCM patients were classified as HCM patients without LGE, with mild LGE-% (0% < LGE-% l 10%), and prominent LGE-% (10% < LGE-%). Results: HCM patients had worse LA functions compared with the controls (p < 0.05). The majority of LA functional indices were more impaired in HCM patients with regard to LGE. LA volumes were higher in HCM patients with prominent LGE-% compared with HCM patients with mild LGE-% (p < 0.05). However, only a minority of LA functional parameters differed between the 2 groups. LA strain parameters showed weak to modest correlations with LV LGE-% and LV edLSR. Conclusions: LV characteristics, to some extent, influence LA mechanics, but they might not be the only factor inducing LA dysfunction in patients with HCM.

Early Valve Thrombosis Management After Successful Transcatheter Tricuspid Valve-in-Valve Implantation.

Transcatheter tricuspid valve-in-valve implantation is a critical option in high risk bioprosthetic tricuspid valve dysfunction. In this case report, balloon-expandable transcatheter heart valve was implanted successfully into the tricuspid valve and early thrombosis was managed successfully. (Level of Difficulty: Intermediate.).

The diagnostic role of "acceleration time" measurement in patients with classical low flow low gradient aortic stenosis with reduced left ventricular ejection fraction.

PURPOSE: In our study, we aimed to assess the role of acceleration time (AT), ejection time (ET), and AT/ET ratio to distinguish between true and pseudo severe AS in patients with classical low flow-low gradient (LF-LG) aortic stenosis (AS) with reduced left ventricular ejection fraction (LVEF). METHODS: Sixty-seven classical LF-LG AS with reduced LVEF patients who underwent dobutamine stress echocardiography (DSE) were included in the study. According to DSE results, all patients were divided into two groups; true AS and pseudo severe AS. Aortic valve calcium score was measured in patients with inconclusive DSE results. AT and other ejection dynamics (ET and AT/ET) were calculated by taking baseline echocardiographic records into account for all patients. The predictive power of AT and other ejection dynamics were evaluated to estimate true and pseudo severe AS. RESULTS: According to DSE results, out of 67 patients, 44 (65.7%) was diagnosed as true severe AS. There was a statistically significant relation between baseline AT and true AS [adjusted OR 4.47 (95% CI 1.93-10.4), p = 0.001]. The best cutoff value of AT was measured as 100 msec according to the Youden index. This value had a sensitivity value of 77%, specificity value of 87%, positive predictive value of 92%, and a negative predictive value of 67%. CONCLUSION: The measurement of AT can predict the DSE outcome and can be used for diagnostic purposes to distinguish between true and pseudo severe AS in classical LF-LG AS patients with reduced LVEF.

Tamoxifen Prevents Peritendinous Adhesions: A Preliminary Report.

Background: Scarless healing comprises the ultimate goal after an injury. Since tendon healing results in a fibrotic scar, an injured tendon can never regain the mechanical potential and strength of its uninjured form. A wide variety of studies focus on the tendon healing with an absent or minimal peritendinous adhesions. However, no simple method has managed it at all. Possible complex actions and peritendinous environmental events take place during the tendon healing process. Tamoxifen (TAM), besides its breast cancer-related usage, is a potent antifibrotic drug. Here, we aimed to reduce the peritendinous adhesion with TAM administration. Methods: Achilles tendons of 44 Wistar albino rats were randomly distributed in 4 groups. In group 1, bilateral lower extremities were used as control and sham. Groups 2 and 3 were comprised of low-dose (1 mg/kg) and high-dose (40 mg/kg) systemic administration of TAM, respectively. Group 4 included local administration (1 mg/kg) of TAM. Biomechanical, macroscopical, and histopathological analyses were done and compared statistically. Biomechanically, the maximum force that led to tendon rupture was determined, and tensile force data were recorded via tensile testing device. Macroscopical and histopathological analysis were composed of the quantity, quality, and grade of peritendinous adhesions. Results: Macroscopic and histopathologic findings revealed that groups 2 and 3 had a variety of values ranging between slight to severe adhesions. In group 2, almost half of the animals had moderate adhesions, whereas in group 3, the majority of the animals had moderate adhesions. There were no animals with moderate or severe adhesions in group 4. Statistically significant values were calculated between sham and control groups. Biomechanically, group 2 showed the most significant result. The tendons in group 2 had the highest stiffness when maximal force was applied to rupture the tendons. Henceforth, all these consequences were proven statistically. Conclusion: We achieved less peritendinous adhesion with the local administration of TAM when compared to systemic administration of TAM. A better understanding of the peritendinous environmental process will reveal to develop new therapies in the prevention of peritendinous adhesions.
