Question

Quizplus · Accepted Answer

The condition described is tricuspid atresia, which occurs when the tricuspid valve fails to develop, leading to an absence of blood flow between the right atrium and ventricle. Tricuspid regurgitation refers to a leaky tricuspid valve, tricuspid stenosis refers to a narrowed tricuspid valve, and transposition refers to a condition where the positions of the pulmonary artery and aorta are switched.
