Abstract
The presence of persistent left superior vena cava to the left atrium connection without an innominate vein may give rise to technical challenges during intracardiac repair. In this report, the end-to-side anastomosis technique of the persistent left superior vena cava to the right superior vena cava is discussed in a patient with tetralogy of Fallot associated with persistent left superior vena cava draining directly into the left atrium. A successful end-to-side anastomosis between the persistent left superior vena cava and the right superior vena cava was performed and short-term anastomosis patency was documented via angiography.
