Successful repair of aortic annulus rupture during transcatheter aortic valve replacement using extracorporeal membrane oxygenation support.

Aortic annular rupture is a rare and much dreaded complication of transcatheter aortic valve replacement. Device oversizing to prevent post-procedural paravalvular leak is the most commonly identified cause of this complication. However, mechanical stress in a heavily calcified non-compliant vessel can also lead to annular rupture in this older population. We describe a case of aortic annular rupture with involvement of right coronary artery ostium leading to cardiac tamponade and cardiac arrest, successfully managed by extracorporeal membrane oxygenation support, open drainage of the pericardial space, pericardial patching of the defect and bypass of the affected vessel with excellent post-procedural results.
