title: Results of one-hundred and seventy patients after elective Bentall operation.
abstract: The aim of this study was to evaluate the short and long-term operative results of patients who underwent a Bentall procedure in a 12-year period. We retrospectively analyzed the data of 170 patients who underwent an elective Bentall procedure between January 1998 and July 2010. All pre- and perioperative variable were entered into a multivariate regression model to identify significant predictors of early and late mortality. The early mortality rate was 11.2% (19/170 patients). Multivariate logistic regression analysis identified prior cardiac operation and cardiopulmonary bypass time as independent risk factors for early mortality, with odds ratios of 5.75 (95% confidence interval: 1.850-17.874; p=0.003) and 1.011 (95% confidence interval: 1.003-1.019; p=0.008), respectively. The Kaplan-Meier curve shows an overall survival of 78%±4% at 5 years and 66%±10% at 10 years. Cox regression analysis revealed no independent risk factors for late mortality. The Bentall procedure is still the procedure of choice for aortic root replacement. Improvements in perioperative management in recent years has improved the early outcome, and in our experience, the late results of this technique were satisfactory.
