What does the transcatheter ASD/VSD closure procedure involve?

This minimally invasive procedure repairs atrial or ventricular septal defects (holes in the heart wall) without open-heart surgery. A thin catheter is inserted through a blood vessel in the groin and guided to the heart, where a small, umbrella-like device is deployed to seal the defect. The entire process is performed under imaging guidance, typically takes 1–2 hours, and leaves no chest scar. Most patients are discharged within 3–5 days.
