Persistent left superior vena cava (PLSVC) is uncommon with an incidence of 0.3%–1.3%. The incidence of absent papillary muscle is unknown. Congenital anomalies of a thoracic venous system associated with absent papillary muscle are very rare. During dissection of a 55-year-old male cadaver, PLSVC with absent papillary muscle was found. Although these congenital anomalies are incidentally found, it is worthwhile following such patients to look for the evolution of any cardiac symptoms. Sound knowledge and awareness of such congenital anomalies are required for radiologists, cardiothoracic surgeons, and critical care physicians.
