Percutaneous Mitral Valve Repair for Acute Mitral Regurgitation After an Acute Myocardial Infarction

Potential advantages of this therapy are, first, the rapid decrease in LV, left atrial, and pulmonary artery pressures and the increase in cardiac output observed after a successful correction of the MR (4), and, second, the avoidance of the LV damage induced by the systemic inflammatory response, free radical injury, and myocardial oxidative stress associated with cardiopulmonary bypass (5). [...]transcatheter mitral valve repair technology also may avoid the restraint of the mitral annular motion caused by mitral rings or prosthesis and the development of abnormal septal motion. [...]the treatment of acute MR with transcatheter mitral valve repair technology in AMI patients appears to be safe and effective, leading to a rapid clinical recovery and persistent clinical improvement at follow-up.
