Objective The standard approach in treating cardiac myxoma is the median full sternotomy. After recent advances in surgical techniques, the mini right anterior thoracotomy has emerged as an alternative method. Methods We performed a retrospective study to compare the clinical outcomes of the mini right anterior thoracotomy approach with those of the sternotomy approach for resection of cardiac myxoma at the Montreal Heart Institute. There were 20 patients treated using a mini right anterior thoracotomy (4–5 cm) and 23 patients were treated using a median sternotomy. Results No early mortalities were found in either group. Although the cardiopulmonary bypass time and aorta cross-clamp time were not significantly different between the two groups (64.3 mn ± 18 and 37.2 mn ± 15 vs 54.3 mn ± 25 and 37.20 mn ± 2), preoperative blood loss (106 mn ± 95 vs 338 mn ± 270) was significantly less in the mini right anterior thoracotomy group. The intensive care unit and hospital stay (1.65 days ± 1.2 and 5.70 days ± 3) were shorter with the mini right anterior thoracotomy approach. Conclusions A minimally invasive surgery through mini right anterior thoracotomy is a good alternative technique for treating cardiac myxoma. Despite the small size of the experience, there is a clear diminution in preoperative blood loss and an interesting trend toward a shorter intensive care unit and hospital stay.
