ABSTRACT Background: Conventional surgery presents significant challenges for elderly patients with atrial myxoma and ascending aorta calcification. This study aims to evaluate the feasibility and safety of total thoracoscopic resection of atrial myxoma. Methods: A total of 83 patients who underwent totally thoracoscopic resection of atrial myxoma were retrospectively analyzed between January 2013 and April 2024. Three 1.0-2.0 cm thoracic incisions were made in the right chest, and procedures were conducted under totally thoracoscopy. The right atrial myxomas were resected via a right atrium approach, while left atrial myxomas were removed through an interatrial septal approach. For 46 patients with ascending aortic plaque or calcification, the operations were performed on the beating heart without aortic cross-clamping. Results: The totally thoracoscopic resection of atrial myxoma was successfully performed without in-hospital mortality in all patients, nor a switch to the sternotomy approach. The duration of operation, CPB time, aortic cross-clamp time in the beating heart group were shorter than in the arrest group. There were no statistically significant differences in mechanical ventilation time, duration of ICU, post-operative hospital stays and postoperative 24h drainage volume. The tracheal extraction rate in the operating room was higher in the beating heart group than that in the arrest group. None of the patients required blood transfusion or experienced serious complications. Conclusion: Total thoracoscopic resection is a feasible and safe method for addressing atrial myxomas, particularly in elderly patients with ascending aortic calcification and persistent cardiac failure.
