With the availability of effective therapy, early disease detection is an important strategic objective to improve treatment outcomes. Resting echocardiography is currently the recommended screening modality for high-risk population groups. However, it is clear that abnormalities in resting hemodynamics (and symptoms) are late sequelae of the pathobiological processes that begin in the distal pulmonary arteries. Exercise stress may unmask early pulmonary vascular dysfunction, however the definition, clinical significance, and natural history of 'exercise PAH' remain undefined. However, based on clinical experience and literature the prevalence is estimated at \\~ 20%.Treatment with endothelin receptor blockers has shown a beneficial influence on the clinical performance in patients with exercise induced PAH due to systemic sclerosis and primary pulmonary hypertension. Whether endothelin receptor blockers decrease pulmonary pressures and improve clinical outcome in patients with exercise induced pulmonary arterial hypertension due to congenital heart disease is unknown.\n\nObjective: Identify congenital heart disease patients with exercise-induced pulmonary arterial hypertension. Analyze changes in pulmonary arterial pressures at peak exercise in patients with exercise induced pulmonary arterial hypertension before and after treatment with bosentan, compared to placebo.\n\nStudy design: Randomized placebo controlled trial with a study period of 26 weeks.\n\nStudy population: Adult congenital heart disease patients with exercise induced pulmonary arterial hypertension (n=40) from the Academic Medical Centre, Amsterdam.\n\nIntervention: After randomization one group (n=20) receives a 125 mg tablet of Bosentan twice daily for 6 months. The other group (n=20) receives placebo for 6 months.\n\nMain study parameters/endpoints: To determine wether bosentan (endothelin receptor inhibitor) decreases mean pulmonary arterial pressure at peak exercise in adult congenital heart disease patients with exercise induced pulmonary arterial hypertension. Furthermore the change in cardiopulmonary exercise capacity and right ventricular function will be investigated.\n\nNature and extent of the burden and risks associated with participation, benefit and group relatedness: All investigations, blood analysis excepted, are non-invasive and free of risk. The burden for the patients mainly consists of the time that is consumed by the investigations, namely: history taking + physical examination (15 min); Quality-of-Life- score (15 min); laboratory tests (electrolytes, creatinine, urea, albumin and neurohormones, troponin T); 12 lead electrocardiogram (10 min); exercise echocardiography (30 min); cardiovascular exercise testing (30 min).\n\nThe trial medication has a potential risk of liver damage, which will be monitored regularly by laboratory testing of liver transaminases."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* adult (\\>18 years) and mentally competent\n* Open or closed septal defect (ASD I/II, VSD, AVSD)\n* Open or closed systemic-to-pulmonary shunt (PDA, PAPVC)\n* Negative pregnancy test\n* Presence of X-PAH\n\n * One of the following criteria, at peak exercise.\n * mPAP \\> 34 mmHg with CO ≤ 10 l/min\n * mPAP \\> 40 mmHg with CO ≤ 15 l/min\n * mPAP \\> 45 mmHg with CO ≤ 20 l/min\n * mPAP \\> 50 mmHg with CO ≤ 30 l/min\n * a PVR (slope pressure/flow plot) of \\> 3 mmHg/l/min\n\nExclusion Criteria:\n\n* Incapable of giving informed consent\n* Pregnancy or lactation (a pregnancy test is offered to every female patient within fertile age)\n* Women of child-bearing age who are sexually active without practising reliable methods of contraception.
