Methods
One hundred eighty-nine patients undergoing isolated aortic valve replacement between January 2007-June 2013 were included in the present study. Postoperative follow-up was complete in 59 patients. Patients with additional surgical procedures such as supracoronary aortic replacement, coronary artery bypass surgery, multiple valve procedures were excluded in order to properly investigate the functional mitral regurgitation. The mean follow-up time was 38.1±28.6 months. All postoperative echocardiographic assessments were done by the same physician. Patient-prosthesis mismatch was present in 19 patients, defined as an effective orifice area index (EOAI) less than 0.85 cm2/m2 BSA (Group 1). The remaining 40 patients without mismatch constitute the Group 2. These two groups were then compared for postoperative functional mitral regurgitation development, left ventricular mass regression, postoperative pulmonary hypertension and postoperative functional capacity.
