Lung function and Cardiopulmonary Exercise Capacity in Patients with Corrected Tetralogy of Fallot

    Summary

    Background: Since surgical repair of tetralogy of Fallot was introduced, follow-up studies have shown that the majority of patients lead actives lives and have no subjective exercise limitation.

    Objectives: To examine lung function, cardiopulmonary functional capacity and echo-Doppler assessment of pulmonary pressure in adult patients 20 years after repair of TOF.

    Methods: Unselected consecutive patients performed full lung function testing, progressive cardiopulmonary exercise, and echo-Doppler assessments of pulmonary pressure.

    Results: Fifty consecutive patients (33 men, 17 women) aged 29 ± 11 years who underwent surgical repair of TOF at age 10.1 ± 10.9 years were enrolled in this study. Patients after TOF showed no restriction (forced expiratory vital capacity 80%, total lung capacity 91%) and had normal oxygen saturation (97%) and 6 minute walking distance (600 meters). Echocardiography showed normal pulmonary pressure and left ventricular ejection function (62%). Cardiopulmonary exercise testing showed mild limitation of exercise capacity with oxygen uptake at maximal effort of 75–78% predicted.

    Conclusions: After corrections of TOF the study patients had normal lung function and pulmonary arterial pressure but mild limitation in their exercise capacity.
