Prosthetic Valve Endocarditis After Y-Incision Aortic Annular Enlargement: A Simple Solution.
Ann Thorac Surg Short Rep
December 2024
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 Eurasian lynx (), a widespread wild felid on the Eurasian continent, is currently classified as "critically endangered" in Germany. Understanding the impact of infectious agents is of particular importance for the continued conservation of these animals, especially regarding pathogens with broad host ranges and risk of interspecies transmission. Feline leukemia virus (FeLV) is known to infect wild and domestic felids worldwide, including several species of lynx, but it has not been reported thus far in the Eurasian lynx.

Division of Cardiovascular Surgery, Department of Surgery, University of Florida Health, Gainesville, Florida.
A 71-year-old gentleman with prior bioprosthetic aortic valve replacement was admitted with aortic valve dehiscence and an aortic root abscess. He underwent reoperative sternotomy, aortic root, mitral valve, and hemiarch replacement. To augment hemostasis, we implanted the "Martin Mattress"-a pericardial patch sutured to the fibrous ridge within the innominate vein, superior vena cava, right atrium, right ventricular outflow tract, and pulmonary artery-which is preferred to modified Cabrol fistula techniques in infectious root pathology.

Surgery for Bentall's endocarditis poses challenges because the infection spreads to the aortic valve annulus, leading to an annular abscess that necessitates reconstruction. We present a straightforward miniskirt Bentall procedure using an annular pericardial patch to treat Bentall's endocarditis with an annular abscess. After removing the former composite graft and debriding the aortic root and annulus, we created a miniskirt-composite graft using a mechanical or bioprosthetic valve, a straight or Valsalva graft, and an annular bovine pericardial patch with a valve prosthetic sizer.

A man in his 50s with diabetes, hypertension and history of multiple percutaneous coronary interventions presented with 3 weeks of fever and worsening shortness of breath. There was clinical suspicion of infective endocarditis with raised infective parameters. Transthoracic echocardiogram showed abnormally thickened, bicuspid aortic valve with suspicion of paravalvular aortic root abscess.
