Insights
A rare post-surgical circular shunt developed after correcting anomalous pulmonary venous connection. Closing the shunt via cardiac catheterization successfully resolved heart failure symptoms in this critical case.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Circular shunts are rare but critical post-surgical complications.
- Anomalous total pulmonary venous connection to the coronary sinus with persistent left superior vena cava is a complex congenital defect.
- Surgical correction can sometimes lead to unforeseen complications.
Abstract:
Circular shunt is a very rare, albeit critical, condition. We present a case of a post-surgical circular shunt that resulted after correction of an anomalous total pulmonary venous connection to the coronary sinus with a persistent left superior vena cava. A left cavo-pulmonary anastomosis was performed; however, she developed heart failure during follow-up. The anastomosis was closed by interventional cardiac catheterisation without complications that led to resolution of heart failure symptoms.
