Multidisciplinary Approach to Right Ventricular Myxoma

Abstract

Right ventricular (RV) myxoma that obstructs the RV outflow tract is rare. Multimodality imaging is crucial due to the curved and triangular shape of the RV anatomy. Incomplete resection by the right atrial approach in cardiac myxomas may be prevented by preoperative imaging with echocardiography, computed tomography and magnetic resonance imaging to provide detailed visualization. Right ventriculotomy may be an alternative approach to the isolated atrial approach to get complete resection of RV myxoma in suitable patients. The preferred surgical treatment is not well defined for ventricular myxomas and careful preoperative planning is essential. Surgical resection should be performed as soon as possible to avoid outflow tract obstruction, which might result in sudden death. The collaboration between cardiologist and heart surgeon and the effective use of imaging tools are essential for successful treatment. In this article, diagnosis and treatment and the heart team approach to RV myxoma are discussed with a demonstrative patient.

Successful management of a rare case of juvenile giant right ventricular myxoma

“…Right-sided myxomas are uncommon (15%–20%), and RV (3%–4%) or pulmonary artery myxomas are exceedingly uncommon ( 6 ). Syncope, pulmonary embolism, chest congestion, and sudden death are complications that can result from obstruction of the outflow of blood from the RV ( 2 , 7 ).…”
