Totally robotic atrial septal defect closure using da vinci S surgical system on beating heart

Abstract

Objective To Summary the first 40 cases underwent robotic atrial septal defect (ASD) closure or atrial septal defect closure combined bicuspid valve plasty (TVP) using "da Vinci S" surgical System on beating heart. Methods 40 cases of atrial septal defect or combined sever tricuspid valve regurgitation were repaired using "da Vinic S" surgical system on beating heart from March 2009 to December 2010 in cardiovascular department of PLA general hospital. The average age was (38 ± 13) yeas old. 23 cases were female and 17 cases were male. All patients were ostium atrial septal defect with or without pulmonary hypertension. The atrial defect diameter was 1.5 -3.5 cm, and the mean diameter was(2. 8 ±1.3)cm. 9 patients had sever tricuspid valve regurgitation. Without sternotomy, the extracorporeal circulation was established through groin artery,groin vein and internal jugular vein cannulation with the guidance of transeophageal echocardiography. 3 ports of 8 mm and 1 working port of 2 cm were made in the right chest wall. After "da Vinci S" syetem was set up, with the assistant of bed-side surgeon, the surgeon completed the atrial septal defect closure or combined tricuspid valve plasty in the surgeon console with three dimensions visualization. During the operation, without cardioplegia administrated and aortic occlusion, the procedure was completed through right atriotomy. The pleural space was insufflated with carbon dioxide to avoid the air embolism. The direct suturing was used in 22 cases and pericardial patch were used in 18 cases. 9 patients accepted concurrent De Vega tricuspid valve plasty. The transesophageal echocardiography were used to evaluate the result of atrial defect closure or tricuspid valve repair. The operation time, robotic using time and cardiopulmonary time were compared with totally robotic atrial defect repair in arrested heart. Results All cases were accomplished successfully without complication. There was no residual shunt and air embolism. The operation time, robotic using time and cardiopulmonary time were less than the arrested group. Conclusion Robotic atrial septal defect closure or combined tricuspid valve repair on beating heart can avoid aortic ocllusion and can be utilized effectively and safely.
