Cardiac myxoma is a common cardiac tumor. Most are found in the left cardiac system, of which 75% of myxomas are located in the left atrium [Pinede 2001], and the origin of the left ventricle is relatively rare. Surgical resection is the most effective method for the treatment of myxoma, but because of the complex anatomy of the left ventricle, most of the reported cases are performed through the traditional median thoracotomy through the ascending aorta and vena cava to establish cardiopulmonary bypass. It is rare to establish cardiopulmonary bypass through the femoral artery and femoral vein to remove left ventricular myxoma under complete video-assisted thoracoscopy. This paper reports the surgical process and perioperative echocardiographic, magnetic resonance, radiological and pathological features of a completely thoracoscopic resection of left ventricular myxoma.
