Insights
A modified Warden technique successfully repaired unroofed coronary sinus defects with a left superior vena cava, avoiding grafts. This surgical approach offers a safe and effective solution for this complex congenital anomaly.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Unroofed coronary sinus defects with a persistent left superior vena cava (LSVC) present surgical challenges.
- Traditional repair often necessitates prosthetic grafts, risking complications like supra-mitral gradients or pulmonary venous obstruction.
Background:
Repair of unroofed coronary sinus defect in the presence of left superior vena cava is challenging and requires prosthetic graft material to redirect flow to the right atrium. This may potentially cause a supra-mitral gradient or pulmonary venous obstruction.
Methods:
Three patients with unroofed coronary sinus in the presence of a left superior vena cava (LSVC) underwent modified cavo-atrial anastomosis (Warden technique) to achieve reimplantation of the LSVC in a retro-aortic fashion to the right atrial appendage.
Results:
Three patients recovered well with no evidence of an intracardiac shunt. Postoperative echocardiography demonstrated normal venous flows in the LSVC.
Conclusion:
This modified technique offers correction of this systemic venous anomaly without the need for any additional graft material.
