Introdution: Ischemic mitral regurgitation (IMR) remains one of the most complex and unresolved aspects of ischemic heart disease that the impact of percutaneous coronary intervention (PCI) on improvement of intensity of ischemic mitral regurgitation is not well clarified. Patients with coronary artery diseases and ischemic mitral regurgitation have a worse prognosis than the patients with coronary artery disease (CAD) and those without ischemic mitral regurgitation. We sought to investigate the impact of complete revascularization by percutaneous coronary intervention PCI on improvement of IMR in patients with CAD and comparisons of echocardiography indices in patients with and without improvement of ischemic mitral regurgitation.
Methods: In this cross sectional retrospective study, echocardiographic reports in pre- percutaneous coronary intervention time and 12 months after PCI of patients with moderate (≥2+) ischemic mitral regurgitation who underwent complete revascularization by percutaneous coronary intervention from Farvardin 1391 to Esfand 1393 were included in the study. Then, echocardiographic data of the patients with improved ischemic mitral regurgitation compared with the patients with non-improved ischemic mitral regurgitation.
Results: Comparison of echocardiographic indices before and after percutaneous coronary intervention revealed that after percutaneous coronary intervention (P = 0.002) in 15 patients (16%), improvement in ischemic mitral regurgitation  was occurred. Also, left ventricular ejection fraction (P = 0.010), left ventricular end- diastolic (P = 0.003) and end-systolic diameters (P < 0.001), wall motion score index (P = 0.003), left atrial area (P = 0.001) and systolic pulmonary artery pressure (P = 0.046) in pre- percutaneous coronary intervention echocardiography were different between improved and none-improved IMR group.
Conclusion:  Although, percutaneous coronary intervention can lead to improvement of ischemic mitral regurgitation but most patients did not show improvement of ischemic mitral regurgitation after percutaneous coronary intervention. The structural abnormality of left ventricle and atrium were different between improved and none-improved IMR group
