Background: This study aimed to assess the accuracy of tricuspid spectral Doppler (E/A) and tissue Doppler parameters (E/E') to diagnose right ventricular diastolic dysfunction (RVDD) in comparison to American Society of Echocardiography (ASE criteria) in pediatric tetralogy of Fallot (TOF) patients after surgical repair.
Methods: This prospective, observational study was done at a tertiary care hospital involving 40 pediatric TOF patients aged less than 2 years who underwent complete intracardiac repair with cardiopulmonary bypass (CPB). Echocardiographic observations were made using a pediatric transesophageal echocardiography probe after surgical repair in the post-CPB period.
Prevalence of transthyretin cardiac amyloidosis in patients with aortic stenosis.

Prince Sultan Cardiac Centre, Heart Function Unit, Department of Adult Cardiology Riyadh, Saudi Arabia.
Background: Transthyretin cardiac amyloidosis (ATTRCA) is a prevalent disease, and it can be associated with heart failure (HF), left ventricle hypertrophy (LVH), atrial fibrillation (AF), and aortic stenosis (AS).
Aim: The study aims to detect the prevalence of ATTRCA in the symptomatic AS population.
Method: A single-center prospective study screening for ATTRCA in patients diagnosed with symptomatic severe AS undergoing aortic valve (AV) intervention.
Iatrogenic diversion of inferior vena cava to the left atrium presented as persistent hypoxemia: Case series.
Medicine (Baltimore)

Department of Center for Pulmonary Vascular Disease, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.
Rationale: The transcatheter closure and atrioseptopexy are the main treatment methods for atrial septal defect (ASD). However, persistent hypoxemia due to iatrogenic diversion of inferior vena cava (IVC) to the left atrium (LA) is reported as a rare complication after ASD closure. Contrast echocardiology is a reliable and powerful tool to detect iatrogenic diversion and identify the etiology accurately.

A comprehensive understanding of the cellular and molecular mechanisms underlying the formation of these characteristic curvatures remains lacking. Here, we demonstrate in zebrafish that the initially similar populations of OC and IC ventricular cardiomyocytes diverge in the organization of their actomyosin cytoskeleton and subsequently acquire distinct OC and IC cell shapes.
