title: Myxoma in the right ventricular outlow tract.
abstract: We present a patient with dyspnea, cyanosis and presyncope during exercise related to intermittent obstruction of the right outflow tract by a myxoma of the right ventricle attached to the membranous interventricular septum by its pedicle. We also review the specific medical and surgical features of such tumors. Right ventricular myxomas are rare benign tumors and clinical manifestations depend mainly on size and site of attachment. They can cause obstructive events, and embolism is also possible. Both forms of clinical presentation are potentially fatal and surgical removal should be urgently scheduled. This is usually curative, although recurrences have been reported, generally when these tumors are part of the Carney complex. The best surgical approach is individualized, and transesophageal echocardiography is an important tool in the decision. In our case right atriotomy was considered the best option.
