Percutaneous Radiofrequency Ablation of Obstructive Right Ventricular Giant Myxoma.

Surgical resection is the conventional therapeutic action for patients with an obstructive cardiac tumor. However, for patients in poor clinical condition, cardiac operation can be risky. We report on the successful percutaneous radiofrequency (RF) ablation treatment of a right ventricular giant myxoma in a 70-year-old woman with right ventricular outflow tract (RVOT) and pulmonary artery stenosis, who was unable to tolerate operation. The treatment was effective in relieving RVOT stenosis and improving symptoms. We believe the RF ablation may also be used as a supplementary technique for the treatment of obstructive cardiac tumors, when only partial resection is possible.
