Purpose : The aim of this study is to retrospectively evaluate the effect of combined aortic regurgitation (AR) on the prognosis, especially echocardiographic results, in patients who underwent aortic valve replacement (AVR) for severe aortic stenosis (AS).
Methods : Among the patients who underwent AVR for severe AS between January 2005 and December 2016, 63 patients (mean age : 68.4±7.4 years, 38 men and 25 women) were enrolled in this study. The patients were classified into 2 groups according to the degree of AR (AS group : 30 patients without AR, AR group : 33 patients with mild to moderate AR). Transthoracic echocardiography was performed preoperatively and postoperatively at 1 week and 1 year.
Results : There was no operative mortality. There were no significant differences in postoperative complications between the two groups. AS group had a larger left ventricular (LV) end diastolic diameter, a higher LV mass index (LVMI), a more LV hypertrophy, a smaller aortic valve area, a higher peak and mean pressure gradient than AR group in preoperative echocardiography. In echocardiographic follow up, LVMI was decreased significantly in AS group than AR group (95.6±6 vs 109.4±4.8, p-value 0.0148).
Conclusion : Combined AR has no influence on postoperative clinical outcome. LVMI was the only echocardiographic parameters showing differences Between the two groups.
