We report a case of minimally invasive cardiac surgery MICS for partial anomalous pulmonary venous return PAPVR to the high portion of the superior vena cava. A 34-year-old female was referred to our hospital for exertional chest oppression, and was diagnosed with PAPVR and a sinus venosus atrial septal defect. Two pulmonary veins were connected to the superior vena cava SVC : one to the SVC-atrial junction and the other to the high SVC adjacent to the azygos connection. We performed an intracardiac repair through a small right axillary incision. The postoperative course was uneventful. MICS may become a useful option for PAPVR repair. Jpn. J. Cardiovasc.
