Successful surgical treatment for a single coronary artery arising from the pulmonary artery

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease
• Cardiac Surgery

Background:

• Aortic coarctation and ventricular septal defect are common congenital heart abnormalities.
• Pulmonary artery banding is a palliative surgical approach for complex heart defects.

Observation:

• A 17-day-old infant presented with aortic coarctation and ventricular septal defect, initially treated with pulmonary artery banding.
• Post-operative ischemic cardiac failure prompted diagnosis of a rare single coronary artery originating from the pulmonary artery.

Findings:

• The infant underwent successful reimplantation of the anomalous coronary artery to the ascending aorta.
• Surgical closure of the ventricular septal defect was also performed concurrently.

Implications:

• This case highlights the importance of considering rare coronary anomalies in infants with complex congenital heart disease presenting with cardiac failure.
• Successful surgical management of single coronary artery originating from the pulmonary artery can lead to favorable long-term outcomes and normalization of cardiac function.
