Experiences in the Surgical Alleviation of Congenital Pulmonic Stenosis

Abstract

Experiences with 115 cases of congenital pulmonary stenosis treated by the direct operative approach of Brock and the operative mortality incurred are reported. A new rongeur for resection of infundibular stenosis is presented. A guillotine-type knife is also presented which has been used successfully to alleviate pulmonary valvular stenosis by a blind closed technique. It is believed that these two technical aids will render it possible more safely and more adequately to relieve the pulmonic obstruction associated with the tetralogy of Fallot and isolated forms of pulmonic stenosis without the necessity for employing the more complicated and inherently more dangerous open techniques.
