Review Meta Analysis Comparative StudyCoronary artery bypass grafting versus combined coronary artery bypass grafting and mitral valve repair in treating ischaemic mitral regurgitation: a meta-analysis.
Ischaemic mitral regurgitation (IMR) is commonly manifested after coronary artery disease, but it is still controversial as to whether coronary artery bypass grafting (CABG) alone improves postoperative outcome. ⋯ Compared with CABG alone, patients who underwent combined CABG and MVR procedures showed a greater improvement in postoperative MR grade, but in terms of in-hospital mortality, MR grade improvement rate, postoperative mean NYHA functional class and five-year survival, adding MVR to CABG surgery lacks evidence to show its superiority.
