Insights
Anomalous aortic origin of the coronary arteries, a rare condition, can cause serious heart problems. Surgical reimplantation of the right coronary artery from the left sinus of Valsalva offers a successful repair method.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Anomalous aortic origin of the coronary arteries (AAOCA) is an uncommon congenital heart defect.
- AAOCA can lead to severe clinical manifestations including angina, myocardial infarction, heart failure, arrhythmias, and sudden cardiac death.
Purpose of the Study:
- To describe the surgical repair of anomalous right coronary artery originating from the left sinus of Valsalva.
- To evaluate the efficacy of the coronary artery reimplantation technique for this anomaly.
Main Methods:
- Case series of 4 adult patients (34-59 years) diagnosed with right coronary artery arising from the left sinus of Valsalva via coronary angiography.
- Surgical repair involving dissection and reimplantation of the anomalous right coronary artery into the right sinus of Valsalva.
Main Results:
- All 4 patients underwent successful surgical reimplantation with no operative mortality.
- Three patients presented with dyspnea and angina; one presented with acute myocardial infarction.
- One patient required postoperative coronary artery stent placement due to associated coronary artery disease.
Conclusions:
- Surgical reimplantation is an effective technique for anomalous right coronary artery from the left sinus of Valsalva.
- This method provides excellent physiological and anatomical repair, addressing ostial abnormalities and preventing coronary artery compression.
- Reimplantation offers superior outcomes compared to coronary artery bypass grafting or the unroofing technique.
Abstract:
Anomalous aortic origin of the coronary arteries is uncommon but clinically significant. Manifestations vary from asymptomatic patients to those who present with angina pectoris, myocardial infarction, heart failure, syncope, arrhythmias, and sudden death. We describe 4 patients, aged 34 to 59 years, who were diagnosed with right coronary artery arising from the left sinus of Valsalva, confirmed by coronary angiography, which was surgically repaired. Three patients presented dyspnea and angina, and one with acute myocardial infarction. At operation, the right coronary artery was dissected at the take-off from the intramural course, and reimplanted into the right sinus of Valsalva. There was no mortality. One patient had associated coronary artery disease that required stent placement postoperatively. This reimplantation technique provides a good physiological and anatomical repair, eliminates a slit-like ostium, avoids compression of the coronary artery between the aorta and the pulmonary artery, and gives superior results to coronary artery bypass grafting or the unroofing technique.

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...

The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...
