Pulmonic Stenosis and Intact Septum

T HE clinical profile, hemodynamic data, and diagnostic criteria of patients with pulmonic stenosis and intact ventricular septum are well known.;' The results of surgery by the Brock method and moderate hypothermia have been amply documented.1 6-10 No rosults of a long-term follow-up of a large number of patients, operated upon by means of the pump oxygenator, are available at the present time. The purpose of the present publication is to present a large group of patients with pulmonic stenosis and intact ventricular septum operated upon by open-heart technic with use of a disc oxygenator, between 1957 and 1961. The preoperative clinical profile is presented briefly, only insofar as it pertains to the severity of the disease, and almost exclusively in charts. The surgical approach is presented briefly. Operative results and postoperative changes in the various clinical and hemodynamic parameters are surveyed in detail.
