The observation of 40 cases of totally robotic myxoma resection / 中华胸心血管外科杂志

ABSTRACT

Objective Objective This study is to discuss a surgical approach for ideal and safe resection of atrial myxoma using da Vinci S surgical system. Methods Forty consecutive patients underwent resection of atrial myxoma with the da Vinci S Surgical System. Mean age of the patients was(48 ± 13) yeas. Mean tumor size was 2. 3 cm ×4. 6 cm ～4. 3 cm ×7. 4 cm. 36 tumors were in the left atrium, of which 31 tumors arose form the interatrial septum, 2 from the postercaudal wall, 2 from the root of the anterior leaflet of the mitral valve, and 1 from the left atrial roof. In 34 patients, exploration was conducted through a left atriotomy anterior to the pulmonary veins and excision was achieved by dissecting a plane through the atrial muscle at the point of attachment. In the first 2 patients, exploration and excision were conducted through an oblique right atriotomy.Four tumors were in the right atrium, all of which were resected from the beating heart. The da Vinci instrument arms were inserted through three 0. 8 cm trocar incision in the right side of the chest via 4 port incision and 2 cm working port, all the procedures were completed with 30 o angled endoscopic facing upward with da Vinci S robot. Results Resection were successful in all patients. There were no operative deaths, strokes or other complication. All the patients were discharged. No recurrences of tumor or septal learkag were found in the follow-up. Conclusion The excision of atrial myxomas with the da Vinci S Surgical System is feasible, efficacious, and safe. Surgical results are excellent.
