ABSTRACT
BACKGROUNDS: We sought to identify short- and long-term changes in postoperative left ventricular systolic function in patients with rheumatic heart disease (RHD) who underwent combined aortic and mitral valve replacement.
METHODS: We analyzed 146 patients according to their preoperative left ventricular ejection fraction (LVEF) (113 with preoperative LVEF???0% and 33 with preoperative LVEF?<50%). A restricted cubic spline model was used to assess the effect of time on the postoperative changes in echocardiographic parameters.
RESULTS: There were no significant difference in preoperative and immediately postoperative LVEF before discharge in either group. During median follow-up of 3.2 years (interquartile range: 1.3-4.7 years) after surgery, postoperative LVEF increased slightly and then plateaued in patients with preoperative LVEF???0%, whereas it increased over 3-4 years after surgery and then gradually decreased in patients with preoperative LVEF?<50% (p?
