Abstract:
A 72-year-old woman with a history of surgical treatment for pulmonary artery sarcoma was admitted with a chief complaint of progressive dyspnea. Transthoracic echocardiography, computed tomography, magnetic resonance imaging, and right cardiac catheterization demonstrated that the tumor had recurred in the right ventricular outflow tract (RVOT) with severe stenosis. Palliative resection of the tumor was performed with cardiopulmonary bypass to relieve the RVOT obstruction. The postsurgical quality of life of the patient improved. Postoperative right cardiac catheterization indicated hemodynamic improvement and no sign of stenosis around the RVOT. About 1 year postoperatively, she is in stable condition and has 5-year-survival from the initial operation.
