Long-term influence of mild or moderate ischemic mitral regurgitation after off-pump coronary artery bypass surgery

Low-dose dobutamine stress echocardiography cannot predict mitral regurgitation reversibility after coronary artery bypass grafting

“…2,4,7,8 The ideal management of IMR remains a clinical dilemma because of the suboptimal available therapeutic options. [9][10][11][12][13] Because the long-term prognosis of uncorrected IMR has been documented to be poor, 10,14 some investigators have proposed surgical correction of IMR, using either repair or replacement, concurrent with coronary artery bypass grafting (CABG). 10,12,[15][16][17][18] However, the greater morbidity and mortality of a combined approach has kept surgeons from widely performing such a correction technique for moderate IMR.…”
