This study reports our initial experience with robotic-assisted partial anomalous pulmonary venous connection (PAPVC) repair. From May 2013 through September 2018, 20 patients (12 male and 8 female) underwent robotic-assisted repair of a right-sided (n = 19) or a left-sided (n = 1) PAPVC. The mean age was 24.6 ± 9.4 years (range 14-44) and the mean body mass index was 22.3 ± 4.6. Seventeen patients had a right-sided supra-cardiac PAPVC with sinus venosus atrial septal defect, two had a right-sided cardiac PAPVC to the right atrium and one had a left-sided cardiac PAPVC to the coronary sinus. Associated anomalies included patent foramen ovale (n = 2) and left persistent superior vena cava (n = 1). All patients were operated on successfully. No conversion to mini-thoracotomy or sternotomy was needed. Cardiopulmonary bypass and aortic clamping times were 114.8 ± 17.3 (range 90-150) and 66.5 ± 15.8 (range 44-90) minutes, respectively. Repair techniques included the single-patch repair with baffle through right atriotomy (n = 16), the 2-patch repair (n = 1) using lateral transcaval incision and intracardiac re-routing (n = 3). The mean ventilation time was 4.2 ± 1.2 h and hospital stay was 3.1 ± 0.1 days. No phrenic nerve injury, sinus node dysfunction, re-exploration or blood transfusion was noted. No residual shunting or venous obstruction was found on echocardiograms. Follow-up was a mean of 1.7 years (range 3-36 months). There was no follow-up mortality. Totally, endoscopic robotic-assisted PAPVC repair is a feasible procedure in selected adult patients. It is a less invasive alternative to traditional incisions, mini-thoracotomy and endoscopic approaches. In the future, new generation robotic devices may offer an alternative for younger patients with this pathology.
