Acquired Pulmonary Artery Stenosis Report of a Case Caused by Mediastinal Tumor

Abstract

An acquired stenosis of pulmonary artery caused by benign cystic teratoma in a 22-year-old female is described. The pulmonary artery stenosis was manifested by the precordial systolic murmurs, distinct pulmonary artery-right ventricular pressure gradient, loud systolic murmurs in the pulmonary artery, and the characteristic picture of compression of the artery evidenced by pulmonary arteriogram. The removal of the tumor resulted in the acquired pulmonary regurgitation of significant degree. Short review of the literature was made and the complexity of the cardiac murmur was discussed.
