Aortic valve replacement with sutureless prosthesis: better than root enlargement to avoid patient-prosthesis mismatch?

Objectives: Aortic valve replacement in patients with a small aortic annulus may result in patient-prosthesis mismatch (PPM). Aortic root enlargement (ARE) can reduce PPM, but leads to extended cardiac ischaemia times. Sutureless valves have the potential to prevent PPM while reducing cardiac ischaemia times.

Is Bentall Procedure Still the Gold Standard for Acute Aortic Dissection with Aortic Root Involvement?

Introduction: The "ideal" treatment of acute aortic dissection type A (AADA) with dissected and dilated root is controversial. We compared the outcome of classical Bentall procedure (biological and mechanical) with valve-sparing David procedure.

Methods: Between January 2002 and July 2011, 119 patients with AADA and aortic root involvement underwent surgery at our center.
