Lung function and cardiopulmonary exercise capacity in patients with corrected tetralogy of Fallot.

چکیده
BACKGROUND Since surgical repair of tetralogy of Fallot was introduced, follow-up studies have shown that the majority of patients lead active 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. 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.

Determinants of physical activity in young adults with tetralogy of Fallot.
BACKGROUND Although sports participation is allowed to most adult patients with corrected tetralogy of Fallot, a reduced exercise tolerance and reduced perceived physical functioning is often present in these patients. We aimed to investigate daily physical activity in adults with tetralogy of Fallot and to investigate the underlying determinants of physical activity in daily life. METHODS We...

Background: Tetralogy of Fallot is the most common cyanotic congenital heart disease. The systolic and diastolic function in both ventricles is altered even after successful corrective surgery for this defect with a transannular patch. Pulmonary regurgitation, a common complication after this treatment, is usually well tolerated in childhood. The aim of this study was to assess the combined dia...

Background Good quality of life correlates with a good exercise capacity in daily life in patients with Tetralogy of Fallot (TOF). Patients after correction of TOF usually develop residual defects as pulmonary regurgitation or pulmonary stenosis of different severity. We investigated the impact of several hemodynamic parameters measured by cardiovascular magnetic resonance (CMR) and echocardiog...
متن کاملRegional ventricular performance and exercise training in children and young adults after repair of tetralogy of Fallot: randomized controlled pilot study.
BACKGROUND Public-health guidelines recommend patients with congenital heart disease to exercise. Studies have shown that patients with congenital heart disease can improve physical exercise capacity. The effect of training on regional ventricular performance has hardly been studied. We performed a pilot study to assess whether an exercise training program would result in adverse changes of reg...
