Right Ventricular Metastasis of Ewing Sarcoma Treated Through Surgical Resection

Toshiki Yokoyama et al. JACC Case Rep. .

Abstract

A 27-year-old man diagnosed with right ventricular metastasis of Ewing sarcoma was referred to our institution. We surgically resected the metastatic tumor to prevent sudden death and reconstructed the right ventricle and tricuspid valve. He has survived for 1 year postoperatively without recurrence.

Keywords: cancer; chordae; papillary muscles; tricuspid valve; valve repair.

Operative Findings (A) The right ventricular wall and part of the ventricular septum were resected with the tumor. (B, C) The papillary muscles of the tricuspid valve during reconstruction. The papillary muscle of the tricuspid valve was stitched to the right ventricular myocardium. (D) The incision of the right ventricle was closed with a bovine pericardial strip.
