Postoperative Monitoring of Right Ventricular Pressures in Cardiac Surgery

Abstract

Abstract Although well recognized and documented clinically, the exact hemodynamic changes immediately prior to death in patients with cardiac lesions and pulmonary hypertension following surgical correction are not known. In an effort to elucidate this problem and to study changes in right ventricular pressure in other instances where it is initially elevated, right ventricular pressures have been monitored postoperatively in a select group of patients. Twenty-two patients encompassing a variety of cardiac lesions have been observed. Of the 22 there were 9 with ventricular septal defects; 6 with pulmonic stenosis, of whom 3 had associated atrial septal defects; 2 with tetralogy of Fallot; 3 with mitral insufficiency; 1 with a ductus arteriosus and intermittent cyanosis, and 1 with an atrial and a ventricular septal defect. Twenty-one of these were repaired with use of the rotating disc type oxygenator and extracorporeal circulation. In the patient with the ductus arteriosus extracorporeal circulation was References 1.
