Background: We present our experience in implementing totally endoscopic 3D endoscopic cardiac surgery without robotic assistance at Cardiovascular Center - E Hospital (Ha Noi – Viet Nam) Patients and methods: Descriptive, retrospective study. Summary of 6.5 years of implementation (6/2017-12/2023). A total of 1275 patients underwent surgery: Men: 515 (%) Mean age: 50.8±14.2 years; Women: 760 (%), Mean age: 50.8±14.2 years. Surgical technique: CPB establish: Peripheral cardiopulmonary bypass was done via femoral vessles and right internal jugular vein. Surgical access incisions: 1.Valve surgery(right mini thoracotomy( 3-5cm incision). 2. Others: ASD, VSD, myxoma tumor, PAVSD: surgical manipulations were performed through 3-4 working ports less than 1,5cm. ASD, right atrial myxoma group: were done on beating heart, normothermia without aortic clamping. The others with cardiac arrest used a trans-thoracic Chitwood aortic clamp, antegrade Custodiol HTK cardioplegic solution. Results: There were 1268 patients of technical success, 6 cases required to converse to full sternotomy because of all causes of bleeding, 1 case of PAVSD extending the trocart hole to 3cm mini thoracotomy. 18 cases reoperated because of hemothorax, 5 stroke complication, 20 hospital death. Endoscopic surgery is applied to more types of diseases over time: valves ( single or combination) congenital, cardiac tumors Conclusion: Using a combination of advanced imaging technology (3D endoscopic) and innovative surgical techniques we have substantially improved the outcomes for cardiac surgical patients. This combination is a “game changer” and will remove the need for robots in cardiac surgery because it is easier, safer and better and a lot cheaper.
