2024年11月25日 · Papillary muscle rupture is a rare but potentially fatal complication that typically follows a myocardial infarction or occurs secondary to infective endocarditis. Acute rupture frequently results in severe mitral valve regurgitation, acute life-threatening cardiogenic shock, and pulmonary edema.

2024年11月25日 · Papillary muscle rupture is a rare but potentially fatal complication, typically occurring after myocardial infarction or due to infective endocarditis. Acute rupture often results in severe mitral valve regurgitation, leading to acute life-threatening cardiogenic shock and pulmonary edema.

2024年11月7日 · Papillary muscle rupture (PMR) is a dangerous complication that can evolve as a consequence of myocardial infarction or infective endocarditis leading to severe acute mitral or tricuspid regurgitation leading to left or right-sided heart failure. Papillary muscle rupture is rare and frequency is estimated in 0.5-5% of myocardial infarctions.

2013年5月7日 · A papillary muscle rupture is a rare cardiac emergency and is most frequently associated with acute myocardial infarction. It is usually fatal and refractory to medical treatment. Once a papillary muscle rupture has been diagnosed, urgent mitral valve replacement is required to correct the hemodynamic deterioration of the patient.

Transthoracic echocardiogram (TTE) demonstrated a left ventricular ejection fraction of 30% with akinesis of the basal to mid inferior and inferolateral walls, and a possible flail posterior mitral valve leaflet with MR, concerning for papillary muscle rupture (PMR) (Video 1A and 1B).

2023年3月6日 · Spontaneous, non-ischemic papillary muscle rupture (PMR) is a rare and life-threatening cardiac emergency. As a rare form of acute heart failure and hemodynamic compromise, urgent evaluation and diagnosis is needed as PMR is often fatal unless emergent repair or valve replacement is instituted.

2020年1月1日 · Presentation: Papillary muscle rupture most often occurs 2 to 7 days after an MI. Patients can present with acute respiratory distress and cardiogenic shock. The clinical course is unpredictable. Early diagnosis and surgical repair is crucial for good outcomes.

Papillary muscle rupture is one of the catastrophic mechanical complications following myocardial infarction. Rupture leads to acute mitral valve regurgitation, pulmonary edema, and cardiogenic shock. Survival is dependent on prompt recognition and surgical intervention.

Rupture of a papillary muscle after myocardial infarction produces a syndrome consistent with cardiovascular col lapse. In a patient with a previously stable condition, acute pulmonary edema and low cardiac output develop, and in tensive resuscitation becomes necessary.

Papillary Muscle Rupture (PMR) is a rare complication (0.5-5%) with high mortality that usually occurs two to seven days after Acute Myocardial Infarction (AMI). However, rapid diagnosis and
