Cardiopulmonary exercise capacity is a significant criterion of life quality. The evaluation of the exercise capacity is important to answer patient-questions concerning every day activity, choice of profession, sports-activity etc. We performed cardiopulmonary exercise testing in 38 patients (age 33.6 +/- 12.0 years, 18 women, 20 men) with different congenital heart disease (5 after surgical repair of tetralogy of fallot, 2 after Mustard-operation in transposition of the great arteries (TGA), 1 single ventricle, 14 atrial septal defect (ASD), 8 ventricular septal defect (VSD), 8 pulmonary valve stenosis (PS)) during outpatient routine control. All tests were performed on upright bicycle with continuous ramp program of 20 Watt increase/minute. Ventilatory values as O2-uptake, CO2-production, minute ventilation (VE) were measured breath-by-breath. Max. VO2 was reduced as average value for every patient group (tetralogy of fallot 60.2 +/- 20.3% pred., TGA 53.0 +/- 0.0% pred., single ventricle 35% pred., closed ASD 71.9 +/- 23.8% pred., ASD 62.7 +/- 30.0% pred., VSD 64.1 +/- 11.7% pred., PS 73.2 +/- 16.0% pred.). Anaerobic threshold was reduced in tetralogy of fallot (35.9 +/- 12.2% pred. max. VO2) and in single ventricle (28.3% p...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
