A survey of uncommon forms of coronary arteries
Insights
This study identified various nonatherosclerotic coronary artery abnormalities in 854 angiograms, including aneurysms, fistulas, and abnormal origins, highlighting diverse cardiovascular conditions.
Area of Science:
- Cardiovascular Imaging
- Interventional Cardiology
- Congenital Heart Disease
Background:
- Coronary artery abnormalities can present with diverse clinical manifestations.
- Nonatherosclerotic causes are less common but clinically significant.
- Accurate diagnosis is crucial for appropriate management.
Purpose of the Study:
- To report the spectrum of coronary artery abnormalities found in a series of coronary angiograms.
- To describe the clinical presentations and outcomes associated with these abnormalities.
- To emphasize the importance of recognizing rare coronary artery pathologies.
Main Methods:
- Retrospective analysis of 854 coronary angiograms.
- Identification and classification of coronary artery abnormalities.
- Review of patient clinical data and outcomes.
Main Results:
- Identified nonatherosclerotic coronary artery aneurysms in 3 cases, with varied outcomes.
- Documented small vascular networks in 2 cases, one associated with pheochromocytoma.
- Observed abnormal coronary artery origins from the aorta in 3 cases.
- Detected a congenital coronary artery-right ventricular fistula in one patient.
- Found abnormally wide coronary arteries in 17 cases of apical hypertrophy.
Conclusions:
- Coronary angiography reveals a range of nonatherosclerotic abnormalities beyond typical atherosclerotic disease.
- These abnormalities, though rare, can lead to significant cardiovascular events and require specific diagnostic and therapeutic approaches.
- Recognition of these diverse coronary artery pathologies is essential for comprehensive patient care.
Abstract:
Among 854 coronary angiograms, we found the following abnormalities of the coronary arteries. Three cases had nonatherosclerotic coronary artery aneurysms. One case, a 27-year-old man with a diffuse lesion, expired after two episodes of myocardial infarction. In 2 other cases the lesions were localized and the patients underwent successful coronary bypass surgery. In 2 cases, a small vascular network was found: a 23-year-old man with pheochromocytoma who also had myocardial injury and pulmonary edema, and a case with contusio cordis who had angina pectoris but had normal coronary arteries. In 3 cases the coronary arteries originated abnormally from the aorta. A congenital right coronary artery-right ventricular fistula was detected in a 17-year-old female with multiple cardiac abnormalities. Abnormally wide coronary arteries were also found in 17 cases with apical hypertrophy, a form of hypertrophic nonobstructive cardiomyopathy.
