One-week Impella CP support for papillary muscle rupture as a bridge to surgery: a case report.

ABSTRACT:

Background

Papillary muscle rupture (PMR) is a catastrophic complication of acute myocardial infarction. However, the best timing and modality of circulatory support for surgery are unknown.

Case summary

A 75-year-old man presented to the emergency room in our hospital for worsening shortness of breath accompanied by chest pain. Transthoracic echocardiograph showed severe mitral regurgitation (MR) with a flail posterior mitral valve leaflet, and coronary angiography demonstrated distal right coronary artery occlusion. We diagnosed as cardiogenic shock due to subacute myocardial infarction and ischaemic PMR. An Impella CP (Abiomed, Danvers, MA, USA) was introduced to improve haemodynamics. Despite the grade of MR was still severe, the mean blood pressure and pulmonary artery
