Response to exercise in patients after total surgical correction of Tetralogy of Fallot.

Abstract

EXERCISE RESPONSE IN TF/James et al. 13. Daly WJ, Bondurant S: Direct measurement of respiratory pleural pressure changes in man. J AppI The patient and control groups, subdivided by sex and body surface area (BSA), were similar in height and weight. When comparing males to males and females to females with BSA 2 1.2 m2, maximal heart rates and working capacities were lower in the patient groups than in the control groups. An inverse relationship was observed between maximal working capacity and age at surgery in both male and female patient groups. By contrast, especially in the males with BSA < 1.2 m2, the mean maximal heart rates and working capacities ADEQUATE RELIEF OF RIGHT VENTRICULAR OUTFLOW TRACT (RVOT) obstruction without the development of significant pulmonary incompetence and closure of the ventricular septal defect are major goals for successful surgical treatment of tetralogy of Fallot. After intracardiac repair, symptoms of hypoxemia and severe exercise intolerance are relieved even in the presence of residual

Exercise Capacity, Residual Abnormalities and Activity Habits following Total Correction for Tetralogy of Fallot

“…Several studies (2,6,11,15) have shown that cardiac output in intense exercise is lower in patients with total correction for tetralogy of Fallot due to a smaller stroke volume. As in the present study maximal heart rate has often been found to be lower (2,11,13), with the exception of the study by Mocellin et al (15). An impaired cardiac output may be partially compensated for by an increase in maximal arteriovenous oxygen difference.…”

“…Several postoperative studies have shown that the majority of patients can enjoy a normal life without symptoms (9,14) and have a fair tolerance to physical exercise (2,6,7,11,13,15). However, hemodynamic and angiographic studies at rest (3.…”

“…119 Postoperative studies of patients with coarctation of the aorta or tetralogy of Fallot have demonstrated findings consistent with underlying ventricular dysfunction. 120,121 These observations should be kept in mind when such patients are evaluated before noncardiac surgery. Patients receiving primary cardiac repair at a younger age in the present era may be less prone to postoperative ventricular dysfunction because of improved surgical techniques.…”
