Totally thoracoscopic surgery for treating left atrial myxoma

We aimed to summarize the experience of totally thoracoscopic surgery for left atrial myxoma, together with analyzing the safety and feasibility. We retrospectively analyzed the clinical data of 15 patients with left atrial myxoma admitted to our hospital from October 2016 to October 2018. The auxiliary hole was located at the midline of the 5th intercostal space of the right chest. The endoscope hole was located at the front position of the fourth intercostal space. Specimens were sent to the pathology department for pathological examination. All the procedures were completed successfully. Extracorporeal circulation time was 46.5 ± 18.6 minute, cross-clamping time was 20.6 ± 6.7 minute, thoracic drainage fluid was 89+60.2 ml, ventilator assist time was 4.3 ± 2.6 hour, intensive care unit stay time was 14.5 ± 4.2 hour, the average postoperative hospital stay was 5.2 ± 1.2 day. There was no death, or red blood cell transfusion during and after surgery. No postoperative complications were reported by the patients. No recurrence of myxoma, residual shunt in the atrial septum and valvular lesions were found after 3months of postoperative cardiac ultrasound examination. Total thoracoscopic surgery for left atrial myxoma was less invasive with satisfactory cosmetic appearance with feasibility and safety. Besides, it caused no serious complications.
