Summary: This clinical trial is studying the use of different levels of oxygen exposure during and after cardiopulmonary bypass in eligible infants to learn about its safety during heart surgery.~In addition to having the various doses of oxygen, patients that participate will also have blood samples, ultrasounds of the head, and brain wave patterns monitored.~The hypotheses of this trial are:~that there w...

Summary: Establish a cardiovascular biomarker profile to help screening for congenital heart disease in infants and children as well as use non-invasive cardiac imaging in combination with such profiling to better predict the need for future cardiac interventions such as open heart surgery or cardiac catheter intervention selected types of with congenital heart disease.

Summary: The purpose of the study is to collect real world data on patient outcomes and evaluate the procedural success and performance of the Lifetech KONAR-MF™ VSD Occluder for patients with ventricular septal defect (VSD).

Summary: The objective of this registry is to gain more insight on the clinical use of the Occlutech perimembranous VSD occluder.

Summary: Ventricular septal defects (VSD) are the most common cardiac congenital heart defect (about 1/3 of patients with congenital heart disease). VSD management is related to hemodynamics and anatomical localization and the occurrence of complications. Small perimembranous VSD without pulmonary hypertension and without significant left to right shunting are tolerated, whereas large VSD with pulmonary hy...
