Abstract
Objective. The aim of this study was to determine the prevalence of moderate ischemic mitral regurgitation (IMR) in the contemporary CABG population. We also aimed to correlate the effective regurgitant orifice area (ERO) of any regurgitant mitral valve in patients with coronary artery disease with the semiquantitative integrated scale of IMR. Design. From March 15 through June 15, 2006, 510 consecutive CABG patients in three tertiary centres were included in the study. All patients showing any sign of mitral regurgitation (MR) at the referring hospital underwent a preoperative transthoracic echocardiographic estimation of the degree of MR using the integrated scale (1-4) and ERO. Results. IMR was found in 141 patients (28%). The... (More)

All patients showing any sign of mitral regurgitation (MR) at the referring hospital underwent a preoperative transthoracic echocardiographic estimation of the degree of MR using the integrated scale (1-4) and ERO. Results. IMR was found in 141 patients (28%). The prevalence of moderate 2+ or worse IMR was 4% (95% CI; 2.5-6.1%) and the ERO corresponding to 2+ IMR or more ranged from 5 to 30 mm2. Fourteen patients had an ERO between 15-30 mm2. Conclusions. According to our study, patients with moderate IMR, defined as an ERO between 15-30 mm2, account for only 2.7% (95% CI; 1.5-4.7%) of a non-emergency CABG population. (Less)
