Objectives: The study aimed to evaluate clinical and paraclinical characteristics of left atrial myxoma and the early result of the minimally invasive procedure to remove left atrial myxoma at E hospital. Subjects and methods: This is retrospective, descriptive study of consecutive patients, who underwent minimally invasive left atrial myxoma rejection, using total or video-assisted endoscopic technique from October 2016 to March 2021 at E hospital. There were 31 patients, consisting of 27 females and 04 males. The mean age was 53 ± 13 years old (from 17 to 74 years old) Results: Preoperative clinical manifestations were diverse. Asymptomatic form was in 3 patients (9.7%), hemodynamic symptoms were in 26 patients (83.9%), embolism symptoms were presented in 4 patients (12.9%), systemic symptoms (25.8. Anemia and elevated erythrocyte sedimentation rates were observed in 45.2% and 74.2%, respectively. Echocardiography results: the average tumor size was 4,8 ± 1,8 cm (from 1.7 to 8 cm), the site of attachment was mainly in the atrial septum (77.4%). Cardiopulmonary bypass time was 158 ± 43 minutes (from 100 to 252 minutes), cross-clamp time was 84 ± 34 minutes (from 42 to 153 minutes). Ventilation time was 10,8 ± 7,0 hours (from 3 to 30 hours), intensive care unit stay was 1,5 ± 1,0 days (from 0.5 to 4 days), and in-hospital stay was 9.5 ± 5.0 days (from 3 to 30 days). There was no hospital mortality. Cerebrovascular accident was presented in one (3.2%), femoral artery stenosis was in one (3.2%), atrial fibrillation after surgery was in one (3.2%). There was no bleeding, that require reoperation, and no other serious complications. Conclusions: Initial results of left atrial myxoma rejection, using minimally invasive total or video-assisted technique wassafe and effectivewith low complications, could be recommended to apply routinely in cardiac surgery centers

Objective: Myxoma is the most common form of non-malignant tumor that arises from connective tissue. Totally endoscopic surgery without robotic assistance can resect the entire atrial myxoma. This study aim to evaluate the early results of this surgical method. Methods: From January 2019 to April 2021, 26 patients (20 females, 6 males, mean age 49.5 ± 14.3) were diagnosed with atrial myxoma. All tumors of those patients were resected by totally endoscopic surgery. We evaluated the early outcome of this method based on the following criteria: mortality rates, conversion to open surgery, cardiopulmonary bypass time, aortic cross-clamp time, postoperative time. Results: Totally endoscopic surgery to resect atrial myxoma was successfully performed in all patients with surgical ports on the thoracic wall. The largest incision was not more than 1.5 cm in diameter. Mean cardiopulmonary bypass time was 134 ± 39 minutes, aortic cross-clamp time was 81.4 ± 26.4 minutes, mechanical ventilation time was 10.5 ± 4.6 hours, ICU length of stay was 2.1 ± 0.9 days, postoperative time was 6.9 ± 5.4 days. We had one case in which the excision of myxoma was performed contemporaneously with mitral valve annuloplasty. Conclusions: Initial outcomes of totally endoscopic surgery to resect atrial myxomas were satisfactory. However, to fully evaluate the effectiveness of this method, we need to conduct a long-term follow-up of these patients.
