    AbstractPersistent left superior vena cava without a right superior vena cava is an extremely rare condition. We report the case of a 65-year-old woman with this condition who underwent mitral valve plasty. During cardiac catheterization, the asymptomatic patient with mitral valve prolapse syndrome was found to have a persistent left superior vena cava without a right superior vena cava. During mitral valve plasty, cardiopulmonary bypass was established using bicaval drainage through the persistent left superior vena cava and the right atrium. A cannula was inserted into the persistent left superior vena cava to provide a large surgical field in the left atrium. We selected a technique that involved direct insertion of an L-shaped cannula into the persistent left superior vena cava and obtained a clear view of the surgical field. Proper assessment of the right superior vena cava is necessary when a persistent left superior vena cava is suspected.
