Prosthetic Valve Endocarditis After Y-Incision Aortic Annular Enlargement: A Simple Solution.
Ann Thorac Surg Short Rep

Department of Cardiac Surgery, University of Michigan, Ann Arbor, Michigan.
The Y-incision aortic annular enlargement (AAE) has been established as a safe and effective technique for upsizing the aortic annulus by 3 to 4 valve sizes. However, concerns have been raised regarding its technical complexity during reoperations, particularly given the extensive enlargement of the aortic annulus and root. We present a case of reoperative aortic valve replacement after previous Y-incision AAE for prosthetic valve endocarditis and aortic root abscess.

The Y-incision/rectangular patch aortic annular enlargement (Y-incision AAE) is our go-to technique for aortic annular/root enlargement at the University of Michigan for its simplicity and effectiveness. A complete aortotomy is used for first-time surgical aortic valve replacements (SAVRs), and a partial aortotomy is frequently used in reoperative SAVR. The Y-incision is made through the left-non commissure, underneath the aortic annulus to the left and right fibrous trigones.

The Y-incision aortic annular enlargement (AAE), first performed in August 2020, offers a safe and more effective alternative for management of a small aortic annulus/root without need for violation of the left ventricular outflow tract, mitral valve geometry, or left/right atria in both first-time aortic valve replacement (AVR) and reoperative AVR. In the first consecutive 119 patients with Y-incision AAE, the median age was 65 (59, 71), 67% female, 28% had previous cardiac surgery, and 2 cases had endocarditis. The preoperative mean gradient was 36 (30, 47), and the native aortic valve area was 0.

Objective: To evaluate the safety and efficacy of a novel aortic annular enlargement technique.
Methods: From August 2020 to February 2022, 50 consecutive cases of aortic valve replacement with Y-incision aortic annular enlargement and other combined cardiac procedures were performed primarily for severe aortic stenosis. Data were obtained through medical record review, The Society of Thoracic Surgeons database, and National Death Index data.
