Abstract
Objectives : Atrial myxomas are rare benign tumors; causing obstructive or embolic complications, and even death, depending on their site and size. Therefore, once diagnosed, it should be surgically resected emergency. Atrial myxomas are present about 75% in left atrium (LA) and about 15% in right atrium (RA). Early diagnosis is a challenge because of nonspecific manifestations, and sometimes is asymptomatic and discovered accidentally during TTE. Minimally invasive cardiac surgery (MICS) has benefits include cosmetically, less pain, shorter intensive care unit (ICU) and hospital stay. Methods: From Jan. 2011 to Sept. 2020, (20) patients (10 Sternotomy, 10 MI) underwent surgery for isolated resection of atrial myxoma. We reported outcomes; cardiopulmonary bypass time (CPB), cross-clamp time, conversion to median ST, length of stay, complications (stroke, renal failure, respiratory failure, reoperation, and infection) , pain, patient′s satisfaction, recurrence and survival. Mean follow-up time was 6 month.Results : There is no significant difference in CPB or cross-clamp time between groups. No MI cases required conversion to a median ST. Length of stay is shorter in the MI group by 2.2 days (p = 0.045). There is no difference in morbidity or mortality between groups.Conclusions: A minimally invasive approach for atrial myxoma resection is safe, feasible, and favored over sternotomy.
