Abstract 355: Relationship between Female Gender and Mortality after Isolated Aortic Valve Replacement

Background: Previous studies have shown that female gender is an independent predictor of increased operative mortality after coronary artery bypass surgery. It remains inconsistent whether female gender is associated with increased mortality after aortic valve replacement (AVR). The purpose of this study is to investigate the role of female gender inoperative mortality after AVR. Methods: The study population included isolated AVR performed between January 2003 and December 2012 at a single Instituation. Results: During this period, 1,262 patients underwent isolated AVR. The major preoperative characteristics and operative outcomes are detailed in the following table. R>Conclusions: In this study, female patients had increased operative mortality after isolated AVR.

Background: Small aortic prosthesis can lead to prosthesis-patient mismatch (PPM). Implanting such small prosthesis remains a controversial issue. This study was done to investigate whether or not PPM causes an increased operative mortality in aortic valve replacement (AVR).Methods: Two-hundred-two consecutive patients undergoing primary AVR in a tertiary hospital were included. The sample was grouped according to the aortic valve prosthesis size: ?21 mm (small) and >21 mm (standard). The effect of variables on outcomes was determined by univariate and multivariable regression analyses.Results: PPM was found significantly more among patients with AVR ? 21mm (P < 0.0001). Moreover, the likelihood of mortality also was significantly higher in these patients (P < 0.0001). Univariate analysis demonstrated small prosthesis size, urgent operation, PPM, female gender, and NYHA Class IV as significant predictors of mortality. Multivariate regression identified female gender, PPM, and urgent operation as the key independent predictors of mortality.Conclusion: PPM and female gender are significant predictors of mortality. Care should be taken to prevent PPM by implanting larger prosthesis especially in females.

The incidence of chylopericardium after cardiac surgery is unusual, but there are documented cases. Those caring for these patients need to be aware of the symptoms and management of chylopericardium because, if left untreated, it may cause catastrophic consequences.
