Introduction
Cardiac myxomas are rare, and approximately 75% of them are known to develop in the left atrium. Clinical symptoms of cardiac myxomas vary from unapparent to lethal complications such as embolisms, acute heart failure, or even sudden death1. Timely diagnosis and urgent surgical treatment are crucial; however, there are a number of patients who die of severe heart failure before surgery2. Here, we report the case of a patient with a large left atrial myxoma that was asymptomatic until the acute onset of heart failure along with refractory shock. Extracorporeal membrane oxygenation (ECMO) was used as a bridge between his transfer and surgery.
