Papillary Muscle Infarction, Mitral Regurgitation, and Long-Term Prognosis

Papillary muscle infarction, mitral regurgitation, and long-term prognosis.

Ischemic mitral regurgitation and non-ST-segment elevation acute myocardial infarction: long-term prognosis.

INTRODUCTION AND OBJECTIVES Ischemic mitral regurgitation (MR) is a common complication of acute myocardial infarction and has a negative impact on prognosis. However, few studies have been carried out on MR after non-ST-segment elevation acute myocardial infarction (NSTEMI). Our objective was to investigate the incidence, clinical predictors and long-term prognostic implications of MR in patie...

Mitral Regurgitation following Myocardial Infarction: the Syndrome of Papillary Mitral Regurgitation.

T H E NORMAL FUNCTIOS OF THE MmRAL valve depends on the anatomic and functional integrity of the entire valwlar apparatus. Mitral regurgi ta t ion results when one of its components is anatomically deficient or functionally inadequate. Mitral regurgitation is uqually secondary to rheumatic involvement of the mitral cusp and its chordz tendinez. Damage to the papillary muscles (without affecting...

Long-term survival after mitral valve surgery for post-myocardial infarction papillary muscle rupture

BACKGROUND Papillary muscle rupture (PMR) is a rare, but dramatic mechanical complication of myocardial infarction (MI), which can lead to rapid clinical deterioration and death. Immediate surgical intervention is considered the optimal and most rational treatment, despite high risks. In this study we sought to identify overall long-term survival and its predictors for patients who underwent mi...

Repair of Acute Post Infarction Mitral Regurgitation with Papillary Muscle Reimplantation - A case report -

A 53-year-old man presenting with dyspnea and chest pain was diagnosed with acute myocardial infarction secondary to occlusion of the left circumflex coronary artery. Urgent revascularization by percutaneous stenting was successfully performed. However, the post-echocardiography revealed a ruptured papillary muscle that was causing severe mitral regurgitation and aggravation of congestive heart...
