Minimally Invasive Robotically Assisted Repair of Partial Anomalous Venous Connection

We describe a novel robotically assisted minimally invasive surgical technique for repair of partial anomalous pulmonary vein connection (PAPVC). Partial anomalous pulmonary vein connection is a rare congenital anomaly that consists in drainage of one or more pulmonary veins into the systemic venous system. Traditionally, large thoracotomy incision and sometimes establishment of cardiopulmonary bypass are needed to redirect the abnormal pulmonary vein to the left-sided reservoir. We describe a robotically assisted, minimally invasive, off-pump technique for the treatment of the left PAPVC in a 57-year-old patient with signs of progressive right ventricular dilatation. The Da Vinci robot was used for mediastinal dissection and isolation of the distal aspect of the left superior anomalous pulmonary vein from the brachiocephalic vein. Through a left minithoracotomy, under direct vision, the pulmonary vein was reanastomosed to the left atrial appendage, thus reconstituting a normal venous return pattern. The use of the da Vinci robot is a valid adjunct for correction of the left PAPVC. It helps mediastinal dissection and allows reconnection of the pulmonary vein to the left venous system via a small thoracotomic incision and without the use of cardiopulmonary bypass.
