High origin of the right coronary artery with congenital heart disease
The Annals of Thoracic Surgery
|April 10, 1999
Insights
A rare case of anomalous coronary artery origin was found alongside ventricular septal defect and patent ductus arteriosus. This unusual right coronary artery anatomy complicated cardiac arrest induction during surgery.
Area of Science:
- Cardiovascular Surgery
- Congenital Heart Disease
- Anatomical Variations
Background:
- Congenital heart defects, including ventricular septal defect (VSD) and patent ductus arteriosus (PDA), are common pediatric cardiac conditions.
- Anomalous origin of the coronary arteries is a rare but significant finding that can impact surgical outcomes.
Observation:
- A patient presented with a complex congenital heart defect involving VSD and PDA.
- A highly unusual origin of the right coronary artery was identified, arising from the distal ascending aorta.
Findings:
- The anomalous right coronary artery's origin from the ascending aorta precluded effective cardiac arrest induction using standard cardioplegia.
- This anatomical variation posed a significant surgical challenge, necessitating modified approaches.
Implications:
- Highlights the importance of detailed preoperative anatomical assessment in complex congenital heart disease.
- Underscores the need for tailored surgical strategies when encountering rare coronary artery anomalies.
- Contributes to the understanding of surgical risks associated with anomalous coronary arteries.
Abstract:
We encountered a case of anomalous high origin of the right coronary artery associated with ventricular septal defect and patent ductus arteriosus. The right coronary artery originated from the distal part of the ascending aorta resulting in unsuccessful induction of cardiac arrest by cardioplegia. We describe this rare case with anomalous origin of the right coronary artery.
