Objectives: Renal transplant improves echocardiographic markers of systolic and diastolic heart functions. The aim of this study was to evaluate the gradual changes in left and right ventricle functions in children and young adults before and after renal transplant.
Materials And Methods: Thirty kidney recipients of median age 13 years (range, 5-19 years) were included the study. Tissue Dopplerimaging from the septal and lateral mitral annulus ofthe left ventricle and free wall of the right ventricle was performed. Right ventricle systolic excursion velocity and tricuspid annular plane systolic excursion were calculated. Systolic and diastolic heart functions-which gained just before transplant, were compared with posttransplant early- term (6 months to 1 year) and long-term (longer than 1 year) functions.
Results: Twelve patients received deceased-donor and 18 patients received living donor renal transplant. Follow-up after transplant was 44 ± 23 months. Left ventricle ejection fractions were normal. The left ventricle, right ventricle, and interventricular septalTei indices were significantly higher before transplant.The posttransplantation early- and late-term results of left ventricle,right ventricle, and interventricular septal Tei indices were similar. Tricuspid annular plane systolic excursion levels were abnormal in 11 patients (36%), and right ventricle systolic excursion velocities were abnormal in 7 patients (23%) before transplant. All tricuspid annular plane systolic excursion levels and 94% ofright ventricle systolic excursion velocities were normal, but left ventricle Tei indices were higher in 8 (26%) and right ventricle Tei indices were higher in 14 patients (46%) at late-term follow-up.
Conclusions: The systolic and diastolic dysfunctions of both ventricles appear to be highly prevalent in pediatric renal transplant recipients, especially soon after transplant, and were shown to usually decrease with time. Improvements in right ventricle dysfunction are slower, even in optimally treated posttransplant patients.

Objectives: Multiple techniques have been proposed for functional fetal cardiology, including pulsed-wave (PW) and tissue Doppler imaging (TDI), Myocardial Performance Index (MPI), annular plane systolic excursion (TAPSE/MAPSE) and spatiotemporal image correlation (STIC). We aimed to compare these techniques' achievability and reproducibility to determine their clinical utility for each cardiac side.
Methods: Uncomplicated pregnancies from 22 to 39 weeks were recruited and images and volumes stored for offline analysis.

Atrial functional mitral regurgitation (AFMR) is a distinct form of MR in patients with atrial fibrillation and heart failure with preserved ejection fraction (HFpEF). Its pathophysiology remains elusive, and data on exercise-related AFMR are scarce. We sought to investigate the impact of acute exercise on AFMR severity and to identify its determinants.

Background: Right ventricular (RV) failure is a well-recognized pivotal prognostic factor of adverse outcomes in pulmonary artery hypertension (PAH), while RV dilation provides significant implications for adaptive or maladaptive changes. PAH is a predominant cause of mortality among patients with connective tissue disease (CTD). This study aims to elucidate the prognostic significance of RV morphology, as assessed by echocardiography (ECHO), in with CTD associated with PAH (CTD-PAH).

Right ventricular (RV) longitudinal strain has emerged as a crucial tool for evaluating RV systolic function in patients with heart disease. The complex anatomy of the RV presents challenges for functional assessment, traditionally conducted using conventional parameters, such as tricuspid annular plane systolic excursion and RV fractional area change. While these conventional methods are simple and practical, they have limitations in reflecting the majority of global RV systolic function.

There are differing opinions in the literature regarding the cardiovascular safety of long-term methylphenidate use. Studies suggest that the drug may increase the risk of hypertension, myocardial infarction, ventricular arrhythmia, sudden cardiac death, cardiomyopathy, heart failure (HF), pulmonary hypertension, and stroke.
