Papillary Muscle Rupture Following Non-ST-Elevation Myocardial Infarction: A Case Report
1Division of Cardiology, University of Minnesota Medical Center, Minneapolis, Minnesota.
Abstract:
Papillary muscle rupture is a serious mechanical complication of acute myocardial infarction typically seen within 5-7 days following transmural ST-elevation myocardial infarction. The incidence of papillary muscle rupture has markedly decreased in the modern era due to improved diagnosis and early coronary revascularization of ST-elevation myocardial infarction. As a result, papillary muscle rupture is increasingly seen following non-ST-elevation myocardial infarction where both diagnosis and revascularization can be delayed. In this report, we describe two cases of papillary muscle rupture following delayed presentation of non-ST-elevation myocardial infarction and delayed recognition of papillary muscle rupture.
Insights
Papillary muscle rupture, a complication of heart attack, is now more common after non-ST-elevation myocardial infarction due to delayed diagnosis and treatment. This report highlights two such cases.
Area of Science:
- Cardiology
- Cardiovascular Medicine
- Medical Complications
Background:
- Papillary muscle rupture is a severe mechanical complication of acute myocardial infarction.
- Historically associated with transmural ST-elevation myocardial infarction (STEMI), occurring 5-7 days post-event.
- Improved STEMI management has reduced its incidence in that context.
