Surgical resection of cardiac myxoma-a 30-year single institutional experience

Background: Primary cardiac tumors are rare and myxoma constitutes the majority. The present study summarizes our 30-year clinical outcomes of surgical myxoma resection. Methods: Between January 1986 and December 2015, 93 patients (30 men, 63 women; mean age, 54.7 +/- 16.6 years) underwent surgical myxoma resection. The most common origin site was the left atrium. Surgery was performed via a biatrial approach in 74.2%, atrial septotomy through right atriotomy in 17.2%, and left atriotomy only in 8.6%. Mean myxoma size based on longest length was 4.73 +/- 1.92 cm (range, 1.2-11.0 cm). Results: The mean follow-up duration was 9.9 +/- 7.8 years (range, 0-29 years). In-hospital mortality was 3.2%. The most common postoperative complication was atrial fibrillation (4.3%). The 5-, 10-, and 30-year survival rates were 92.9%, 87. 2%, and 75.5%, respectively. Recurrence occurred in two patients (2.1%), which were detected at 20 and 79 months after the first surgery, respectively. Conclusions: Long-term survival after myxoma resection was excellent and recurrence was rare. Based on our experience, surgical method did not affect the outcome.
