for a first mitral valve reoperation , the predictors were advanced age ( p less than .0001 ) , preoperative shock or cardiac arrest ( p = .01 ) , previous aortic or tricuspid valve operations ( p = .02 ) , type of mitral valve procedure ( risk for repair of periprosthetic leak was greater than mitral valve replacement which was greater than mitral valve-conserving operation [ p = .05 ] ) , and impaired left ventricular function ( p = .059 ) .
