Successful surgical treatment of a right atrial myxoma with hypothermic circulatory arrest and venous cannulation in pulmonary artery.

Myxomas are the most common type of benign cardiac tumors, and the right atrium is the second most common location among them, with an incidence ranging from 8.6% to 20% of all cardiac myxomas. Herein, we described a rare case of right atrial myxoma originating from the inferior vena cava orifice. In this case, main pulmonary artery cannulation and moderate hypothermic circulatory arrest were helpful to obtain a clear and simple view of the operative field without blood, which led to complete resection of the tumor with safety and better outcomes with no future recurrence.
