Summary: The goal of this clinical trial is to learn if a specific type of exercise training (high intensity interval training) can improve exercise capacity in people with a congenital heart defect that required the creation of a new connection between the right ventricle and pulmonary artery. This includes people with a truncus arteriosus, pulmonary atresia with a ventricular septal defect or severe tetr...

Summary: The purpose of this two-way cohort study was to explore whether an integrated prenatal and postnatal treatment model for neonates with critical congenital heart disease (CCHD) could be effective in avoiding preoperative morbidities, creating an ideal timing for surgery, thereby reducing postoperative in-hospital mortality, and improving surgical prognosis compared with the traditional model of car...

Summary: The MASA Valve Early Feasibility Study (MVEFS) multi-site interventional clinical trial within the United States of America with each center following a common protocol.The objective of the trial is to evaluate the safety and probable benefit of MASA Valve in the indicated subset of patients requiring Right Ventricular Outflow Tract Reconstruction (RVOTR). As an early feasibility study, the purpos...

Summary: ventricular septal defect(VSD) are one of the most common significant CHD and account for up to 40% of all cardiac abnormalities.VSD is commonly isolated defect as well as intrinsic component of several complex cardiac malformations including tetrology of fallot ,double- outlet right ventricle(RV),transposition of great vessles,aortic coartication or interruption ,and truncus arteriosus

Summary: The goal of this randomized controlled trial is to identify the effects of percutaneous interventions for branch PA stenosis on exercise capacity in patients with d-TGA, ToF and TA. The main question\[s\] it aims to answer are: The primary study objective is to identify the effects of percutaneous interventions for branch PA stenosis on exercise capacity in patients with d-TGA, ToF and TA. The sec...
