Key result
Autologous coronary sinus tissue successfully reconstructs persistent left SVC during OHT.
Why the study?
Management of heart transplantation in patients with persistent left superior vena cava requires specific surgical techniques to ensure venous return.

Orthotopic heart transplantation using a standard bicaval technique with an autologous coronary sinus tissue conduit is a viable approach for managing patients with a persistent left superior vena cava.
Supports feasibility of autologous coronary sinus conduit in persistent left SVC heart transplant; hypothesis-generating, requires validation before wider adoption.
A 56-year-old male presented with severe exertional dyspnea and pitting edema in the lower extremities. The pre-operative evaluation demonstrated biventricular dysfunction associated with severe tricuspid valve regurgitation and a persistent left superior vena cava. He was registered as a transplantation candidate, and orthotopic heart transplantation was performed using the standard bicaval technique. The left superior vena cava was connected to the right atrial appendage after the construction of a conduit using the recipient's autologous coronary sinus tissue. One-month postoperatively, computed tomography imagery demonstrated a patent conduit between the left superior vena cava and right atrial appendage.

Lee et al. (2014) conducted a case report in Biventricular dysfunction with persistent left superior vena cava (n=1). Orthotopic heart transplantation with left SVC reconstruction using autologous coronary sinus tissue was evaluated on Surgical success and conduit patency. Orthotopic heart transplantation was successfully performed in a patient with a persistent left superior vena cava by reconstructing the left SVC with an interconnecting conduit made from autologous coronary sinus tissue.
