Early result of minimally invasive left atrial myxoma resection at Cardiovascular Center - E hospital

Objectives: The study aimed to evaluate clinical and paraclinical characteristics of left atrial myxoma and the early result of minimally invasive left atrial myxoma resection at E hospital. Patients 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 (range [17-74]). Results: Preoperative clinical manifestations were diverse. Asymptomatic form was in 3 patients (9.7%), hemodynamic symptoms were in 26 patients (83.9%), embolism were presented in 4 patients (12.9%), systemic symptoms were in 8 patients (25.8%). Anemia and elevated erythrocyte sedimentation rates were observed in 45.2% and 74.2%, respectively. Echocardiography results: the average tumor size was 4.2 ± 1.7 cm (range [1.7-8]), the site of attachment was mainly in the atrial septum (77.4%). Cardiopulmonary bypass time was 158 ± 43 minutes (range [100-252]), cross-clamp time was 84 ± 34.2 minutes (range [42-153]), ventilation time was 10,8 ± 7,0 hours (range [3-30]), intensive care unit stay was 1,5 ± 1,0 days (range [0.5-4]), and in-hospital stay was 9.5 ± 5.0 days (range [3-30]). 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 resection, using minimally invasive total or video-assisted technique wassafe and effectivewith low complications, could be recommended toapply routinely in cardiac surgery centers.
