Methods From October 1995, through August 1996, 91 patients (44 male and 47 female) received video assisted cardiac surgery (VACS). Their ages ranged from 1 year to 79.5 years (25.7±21.7). Indications for surgery were atrial septal defect (59 patients), ventricular septal defect (15), coronary artery disease (4), severe mitral regurgitation (4), severe tricuspid regurgitation (3), thrombosis of mitral mechanical prosthesis (3), left atrial tumor (2), and left ventricular thrombus with dilated cardiomyopathy (1). The VACS was performed through right or left anterior minithoracotomy and guided by video assisted endoscopic techniques by means of projected images on the video monitor under extracorporeal circulation. The aorta was not cross clamped and the myocardium was protected by continuous coronary perfusion with hypothermic fibrillatory arrest (rectal temperature 22.6±4.0℃). Conventional instruments were used. Results All lesions were corrected successfully. The bypass time was 27 to 335 minutes (72.8± 52.7). The operative time was 1.3 to 8.5 hours (3.0± 1.7) . There were no operative deaths and 3 late deaths. Follow up was complete in all survivors (6 to 16 months, mean 8.7). Most of them were found to be in NYHA functional Ⅰ or Ⅱ. Conclusion Our preliminary experiences demonstrate that VACS is simple and effective in surgical correction of selected cardiac lesions. Short term results show good outcomes.展开更多
