title: Recognition of persistent left superior vena cava in non-congenital patients undergoing cardiac surgery.
abstract: Persistent left superior vena cava (PLSVC) represents the most frequent congenital malformation of the thoracic venous drainage system. In adults referred to surgery for an acquired cardiac disease, abnormal venous drainage may be missed if not carefully researched. Discovering a previously undiagnosed PLSVC during cardiopulmonary bypass (CPB) may present some inconvenience for both the perfusionist and the surgeon, especially during a minimally invasive approach. The authors believe PLSVC probably may represent an under-reported condition. A careful screening of patients undergoing cardiac surgery may prove helpful. In particular, a complete echocardiographic study may help to better diagnose this condition before surgery. Different signs may raise the suspicion of PLSVC and should be carefully researched during preoperative patient work-up.
