Insights
Coronary artery anomalies occur in 1.5% of patients. Recognizing these congenital heart variations is crucial for accurate diagnosis, angiography, and surgical safety.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Medical Imaging
Background:
- Coronary artery anomalies (CAAs) are often linked with congenital heart disease (CHD).
- Accurate identification of CAAs is vital to prevent diagnostic errors, surgical complications, and angiography challenges.
Purpose of the Study:
- To determine the prevalence of CAAs.
- To identify associated congenital anomalies in patients with CAAs.
Main Methods:
- Retrospective analysis of 66,884 patients undergoing coronary arteriography.
- Data collected from 1972 to 1982 at the Cleveland Clinic Foundation.
Main Results:
- 1,000 patients (1.5%) had CAAs.
- 101 patients with CAAs had associated congenital anomalies, including mitral valve prolapse (29), bicuspid aortic valves (18), and tetralogy of Fallot (16).
- Ectopic origin of coronary arteries was the most common CAA, with 30 originating from the sinus of Valsalva.
Conclusions:
- CAAs are relatively common and frequently associated with other congenital heart defects.
- Awareness and recognition of CAAs are essential for optimal patient management in cardiology and cardiac surgery.
Abstract:
Coronary artery anomalies are commonly associated with congenital heart disease. It is important to recognize these anomalies to avoid errors in diagnosis, decrease technical difficulties in angiography, and prevent inadvertent injury in surgery. We found that of 66,884 patients who underwent coronary arteriography between 1972 and 1982 at the Cleveland Clinic Foundation, 1,000 had coronary anomalies. Of these, 101 had associated congenital anomalies: 29 had mitral valve prolapse, 18 had bicuspid aortic valves, 16 had tetralogy of Fallot, 11 had corrected transposition, 10 had a univentricular heart, 6 had coarctation of the aorta, 3 had ventricular septal defects, and 8 had miscellaneous congenital heart defects. The most common coronary anomaly was ectopic origin of a coronary artery: 30 from the sinus of Valsalva, 12 from the ascending aorta, 11 from the pulmonary artery. Nineteen patients had no left main trunk. Thirteen patients had coronary artery fistulas and 21 had miscellaneous coronary anomalies.
