Ten Years Experience of Aortic Root Replacement Using a Modified Bentall Procedure with a Carrel Patch and Inclusion Technique

Abstract

Objective: A modified Bentall procedure with a Carrel patch and inclusion technique (Modified Bentall Procedure) has been used to treat combined disease of the aortic valve and aortic root. The current study examined the outcomes of this surgical technique.
Materials and Methods: Between April 1999 and March 2009, 16 patients (10 males, 6 females; 63.3 ± 9.4 years) underwent elective surgery involving the Modified Bentall Procedure and no additional surgery, so they were included in the study.
Results: The mean cardiopulmonary bypass time was 140.2 ± 34.4 min (range: 97–232 min), and aortic cross-clamp time was 97.3 ± 16.6 min (range: 76–132 min). There were no hospital deaths. No patients required additional surgery to correct excessive bleeding. The follow-up rate was 100% (16/16). The mean follow-up period was 5.6 ± 2.8 years (range: 0.7–9.9 years). One of the 16 patients died (6.3%) due to lung cancer, and 1 of the 15 surviving patients required additional surgery (6.7%) for a thoracic aortic aneurysm. Kaplan-Meier analysis found that 1-year and 5-year survival and event-free survival rates were all 100%.
Conclusions: The Modified Bentall Procedure provided satisfactory results over both the short term and long term.
