Complex Interventions in the Adult with Congenital Heart Disease: Percutaneous Solutions for Venous Baffles, Coronary Artery Fistulas, and Ruptured Sinus of Valsalva Aneurysms.

We describe 3 distinct ACHD lesions amenable to percutaneous repair: (1) venous baffle obstruction in transposition of the great arteries, (2) coronary artery fistulas, and (3) ruptured sinus of Valsalva aneurysms. For each entity, we chronicle the typical clinical scenario and indications for intervention to supplement the technical approach and potential pitfalls with treatment.
