A Systemic Review and Meta-Analysis: Bentall Versus David Procedure in Acute Type A Aortic Dissection
In this systemic review and meta-analysis, the authors compared outcomes for patients undergoing aortic root replacement to those undergoing a David operation. Mosbahi and colleagues analyzed 27 studies that included a total of 3058 patients with acute type A aortic dissections. In-hospital mortality and midterm survival both favored aortic valve reimplantation. Freedom from valve-related reintervention was 100% (confidence interval (CI) 93.7 - 100%) in patients who underwent reimplantation compared to 94.6% (CI 86.7 - 99.1%) for a composite valve graft intervention. The authors conclude that in type A dissection the reimplantation procedure (David operation) provided a superior outcome.
