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

Abstract

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.

Keywords: hypothermic circulatory arrest; inferior vena cava orifice; right atrial myxoma; venous cannulation in pulmonary artery.

Figure 1
(a) Transesophageal echocardiography demonstrated that the mass was 42 × 28 mm in size, located in the inferior cavity of the right atrium, and was multi-lobulated, pedunculated, and highly mobile. (b) Coronary CT revealed a stalk on the endocardium of the IVC orifice (white arrow).

Intraoperative findings. (a) With two venous cannulas both in the superior vena cava and the main pulmonary artery, cardiopulmonary bypass was started. Through a lateral right atriotomy, a lobulated, gelatinous, and smooth surfaced tumor, 43 × 38 mm in diameter, was found. (b) The deficit of the endocardium (black dot circle) was closed with autologous pericardium.
