Insights
An elderly woman experienced a myocardial infarction due to left main coronary artery occlusion, likely from a blood clot. Echocardiography revealed a contained myocardial wall rupture, leading to fatal cardiogenic shock.
Area of Science:
- Cardiology
- Cardiovascular Medicine
- Interventional Cardiology
Background:
- An 82-year-old female presented with anterior wall myocardial infarction and cardiogenic shock.
- The patient had a history of chronic atrial fibrillation without oral anticoagulation.
Observation:
- Coronary angiography revealed left main coronary artery occlusion originating from the right sinus of Valsalva.
- Transthoracic echocardiography demonstrated an incomplete contained rupture of the interventricular septum's apical portion.
Findings:
- The clinical presentation, atrial fibrillation, and normal coronary arteries suggested a thromboembolic etiology.
- The contained rupture contributed to extensive left ventricular damage.
Implications:
- This case highlights a rare cause of myocardial infarction and cardiogenic shock.
- Prompt diagnosis and management of thromboembolic events in patients with atrial fibrillation are crucial.
- Understanding contained myocardial rupture is vital for managing complex cardiac emergencies.
Abstract:
An 82-year-old female was admitted to the coronary care unit with an anterior wall myocardial infarction and cardiogenic shock. She was in chronic atrial fibrillation without oral anticoagulation. Coronary angiography showed occlusion of the left main coronary artery which originated together with a normal right coronary artery from the right sinus of Valsalva. The advanced age, the presence of chronic atrial fibrillation not anticoagulated and the normal appearance of the remaining coronary arteries suggested a thromboembolic origin. Transthoracic echocardiography showed an abrupt interruption of the myocardial wall, in the apical portion of the interventricular septum, not communicating with the pericardial sac or right ventricular cavity suggesting the presence of an incomplete contained rupture of the myocardial wall at this location. She died in cardiogenic shock due to the extensive left ventricular damage.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
