Key result
In a patient with AMI and IMR, mitral regurgitation area increased 5 days post-PCI but decreased to a lower steady level at 3 months, suggesting this as a suitable time for evaluating recovery.
Why the study?
Ischemic mitral regurgitation is a common complication of acute myocardial infarction and the timing for evaluating mitral regurgitation recovery after PCI is unclear.
Does percutaneous coronary intervention improve ischemic mitral regurgitation in a patient with STEMI?

Does percutaneous coronary intervention improve ischemic mitral regurgitation in a patient with STEMI?
Three months post-PCI may be a suitable time point for evaluating IMR recovery and the necessity of surgical intervention in AMI patients.
Ischemic mitral regurgitation (IMR) is a common complication of acute myocardial infarction (AMI). Current evidences suggest that revascularization of the culprit vessels with percutaneous coronary artery intervention (PCI) or coronary artery bypass grafting can be beneficial for relieving IMR. A 2.5-year follow-up data of a 61-year-old male patient with ST-segment elevation AMI complicated with IMR showed that mitral regurgitation area increased five days after PCI, and decreased to lower steady level three months after PCI. This finding suggest that three months after PCI might be a suitable time point for evaluating the possibility of IMR recovery and the necessity of surgical intervention of the mitral valve for AMI patient.

Tu et al. (2016) conducted a case report in ST-segment elevation acute myocardial infarction complicated with ischemic mitral regurgitation (n=1). Percutaneous coronary intervention (PCI) was evaluated on Mitral regurgitation area. In a patient with AMI and IMR, mitral regurgitation area increased 5 days post-PCI but decreased to a lower steady level at 3 months, suggesting this as a suitable time for evaluating recovery.
