Two-dimensional echocardiographic diagnosis of papillary muscle rupture
Abstract:
A 69-year-old man developed a rupture of the papillary muscle on the fifth day of acute posterior myocardial infarction. The two-dimensional echocardiographic features of ruptured papillary muscle included (1) mobile mass of echos attached to normal chordae tendineae in the left ventricle, (2) absent tip of papillary muscle, and (3) mitral valve prolapse. Noninvasive, two-dimensional echocardiography can reveal correct diagnosis of ruptured papillary muscle suspected clinically.
Insights
A ruptured papillary muscle, a rare complication of myocardial infarction, was diagnosed using echocardiography. This noninvasive imaging technique accurately identified key features of the condition.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Acute myocardial infarction (MI) can lead to various mechanical complications.
- Papillary muscle rupture is a severe, though uncommon, post-MI complication requiring prompt diagnosis.
Observation:
- A 69-year-old male presented with symptoms suggestive of a cardiac event.
- Echocardiography revealed a mobile echogenic mass in the left ventricle, absence of the papillary muscle tip, and mitral valve prolapse.
Findings:
- The echocardiographic findings were consistent with a ruptured papillary muscle.
- Two-dimensional echocardiography successfully identified the characteristic features of this rare complication.
Implications:
- Two-dimensional echocardiography is a valuable noninvasive tool for diagnosing suspected papillary muscle rupture.
- Early diagnosis via echocardiography is crucial for timely management of this life-threatening condition.
