Occlusion of the left main coronary artery secondary to left ventricular angioma
Chest
|October 1, 1976
Insights
A rare left ventricular angioma causing complete left main coronary artery occlusion was diagnosed using cineangiography. Surgical treatment involved a double aortocoronary bypass, leaving the angioma intact.
Area of Science:
- Cardiovascular Medicine
- Cardiac Surgery
- Interventional Cardiology
Background:
- Left ventricular angiomas are rare cardiac tumors.
- Coronary artery occlusion can lead to severe myocardial ischemia.
- Left main coronary artery disease poses significant mortality risk.
Observation:
- A patient presented with an angioma on the anterior wall of the left ventricle.
- The angioma resulted in complete occlusion of the left main coronary artery.
- Pre-operative diagnosis was established through cineangiographic imaging.
Findings:
- Successful surgical intervention was achieved with a double aortocoronary bypass.
- The bypass provided revascularization to the left anterior descending and obtuse marginal arteries.
- The cardiac angioma was intentionally left undisturbed post-surgery.
Implications:
- This case highlights the importance of advanced imaging in diagnosing rare cardiac masses.
- Surgical bypass can be an effective treatment for coronary occlusion caused by cardiac tumors.
- Management strategies may involve preserving the primary tumor if revascularization is successful.
Abstract:
Our experience with a patient who had an angioma of the anterior wall of the left ventricle that produced complete occlusion of the left main coronary artery is presented. Diagnosis was made before surgery from findings on cineangiographic studies. Successful surgical treatment consisted of a double aortocoronary bypass to the left anterior descending and obtuse marginal coronary arteries. The angioma was left undisturbed.
