Congenital heart disease; structural abnormalities of the heart or great vessels present from birth.

A congenital narrowing of the aorta, typically near the ductus arteriosus, that obstructs blood flow to the body.

Measurement parameter for assessing pulmonary valve function and regurgitation severity.

Progressive narrowing of a surgically placed conduit connecting the right ventricle to the pulmonary arteries.

Duration that the aorta is clamped during cardiac surgery, directly correlating with ischemic time and surgical risk.
