Percutaneous mitral valve repair in patients developing severe mitral regurgitation early after an acute myocardial infarction: A review

Abstract

Acute mitral regurgitation (MR) may develop in the setting of an acute myocardial infarction (AMI) because of papillary muscle dysfunction or rupture. Severe acute MR in this scenario is a life-threatening complication associated with hemodynamic instability and pulmonary edema, and has been linked to a worse prognosis even after reperfusion. Patients treated solely with medical therapy have the highest mortality rates. Surgery has been the only treatment strategy until recently, but the results of the technique are hindered by high rates of morbidity and mortality. Therefore, the development of less invasive interventions for correcting MR would be ideal. We aimed to review the current role of transcatheter interventions in this clinical setting.

Reparación percutánea borde a borde de la insuficiencia mitral aguda por rotura de músculo papilar en el contexto de infarto agudo de miocardio

“…Esta complicación se presenta habitualmente con insuficiencia mitral aguda grave, edema pulmonar y shock cardiogénico, y es más frecuente en pacientes ancianos, con pobre circulación colateral, tiempo de isquemia prolongado e infartos con afectación de la coronaria derecha o de la arteria circunfleja. La forma más frecuente es la rotura del músculo papilar posteromedial (2) .…”
