Aortic valve replacement in patients with protruding coronary artery stents

Abstract

We present two cases of aortic valve replacement (AVR) in patients with protruding coronary artery stents from the coronary ostia. In the first case, an 87-year-old female was referred for AVR due to severe aortic stenosis (AS). During the operation, we found stents protruding from the left and the right coronary ostia into the aortic root. We performed AVR with a mechanical valve and coronary artery bypass grafting with the saphenous vein to the left anterior descending artery. In the second case, a 77-year-old female was referred for AVR due to severe AS with a history of healed infective endocarditis. During surgery on the second patient, we found a stent protruding 7 mm from the left coronary ostium into the aortic root. The edge of the stent was trimmed, and AVR with a mechanical valve was performed. In both patients, we decided to use a mechanical prosthesis instead of a bioprosthesis because of the risk of leaflet injury. Herein, we discuss some issues regarding patients with AS requiring AVR with prior history of coronary stenting in the coronary ostia.
