Objective

This study aims to assess the risk of adding a Bentall's procedures to a standard AVR operation.

Methods

A retrospective, single unit review was undertaken of patients undergoing a modified Bentall's procedures from January 2000 to February 2015. The observed mortality and mobility of our patients undergoing a modified Bentall's procedure was compared to the expected mortality and morbidity of the same cohort of patients if they were to undergo an AVR only, using the STS database to predict risk. Any difference found can be attributed to replacing the ascending aorta

Results

128 patients were identified between January 2000 and Februrary 2015. No statistically significant difference was demonstrated in the Bentall's group versus the predicted AVR-only cohort with respect to the expected number of deaths, strokes, renal failures, reoperations and prolonged intubations. However, the Bentall's group did exhibit significantly fewer longer stays.

Conclusion

Our results show the lack of increased risk associated with Bentall's procedure adds support in adopting a more aggressive approach to replacing the ascending aorta at the time of AVR.
