When the pressure in the pulmonary arteries levels the systemic blood pressure, blood begins to shunt from the right side of the heart to the left side of the heart leading to a condition with cyanosis, impaired physical capacity and increased mortality (Eisenmengers syndrome).\n\nSeveral clinical trials have shown that there is a beneficial effect of treating patients with primary pulmonary arterial hypertension with Bosentan or Sildenafil and that a combination of these may have an additive or even synergistic effect. No clinical trials with Sildenafil and Bosentan has been conducted for patients with Eisenmengers syndrome. Observational studies and case stories indicate however that the effect of Bosentan or Sildenafil in patients with Eisenmengers syndrome may be as promising in these patients as in patients with primary pulmonary arterial hypertension.\n\nWe would like to examine the effect of treating patients with Eisenmengers Syndrome with a combination of Bosentan and Sildenafil.\n\nThe primary end point is change in physical performance measured with six minutes walking test.\n\nSecondary end points is change in saturation, NYHA class, cardiac output (cardiac catheterization and innocor measurement), pulmonary vascular resistance (cardiac catheterization) shunt ratio (MRI), strain of right ventricle (BNP and echocardiography), quality of life and serum erythropoitin.\n\nThe trial is designed as a randomized, single centre, placebo controlled, double blind cross over study.\n\nTwenty patients with Eisenmengers syndrome is included. All patients will be treated in three months with Bosentan. There after patients will be randomized to receive either Sildenafil (50 mg tid) or placebo as add on therapy for three month. Hereafter a cross over will be made and patients in combination treatment will receive only their native treatment and vice versa.\n\nExaminations for primary and secondary endpoints will be made at baseline, before cross over and at the end of the study. All up titrating of medication will be performed during admittance. Patients will during the study period be close monitored with registration of adverse advents, physical examination and blood tests.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Eisenmenger syndrome\n* Negative pregnancy test\n\nExclusion Criteria:\n\n* Elevated liver enzymes to more than 3´times normal value\n* Hypotension (SBP \\< 90 mmhg).\n* Mandatory treatment with nitrates\n* Myocardial infarction within 3 months\n* Stroke within 3 months\n* Known allergy to Bosentan or Sildenafil\n* inherited degenerative diseases in retina\n* Breast feeding\n* Suspicion of risc of noncompliance.'}, 'identificationModule': {'nctId': 'NCT00303004', 'briefTitle': 'Combination Treatment With Bosentan and Sildenafil to Patients With Eisenmengers Syndrome', 'organization': {'class': 'OTHER', 'fullName': 'Rigshospitalet, Denmark'}, 'officialTitle': 'Combination Treatment With Bosentan and Sildenafil to Patients With Eisenmengers Syndrome', 'orgStudyIdInfo': {'id': '01000'}}, 'armsInterventionsModule': {'interventions': [{'name': 'Bosentan and Sildenafil', 'type': 'DRUG'}]}, 'contactsLocationsModule': {'locations': [{'zip': '2100', 'city': 'Copenhagen', 'country': 'Denmark', 'facility': 'Rigshospitalet', 'geoPoint': {'lat': 55.67594, 'lon': 12.56553}}], 'overallOfficials': [{'name': 'Lars Soendergaard, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Rigshospitalet, Denmark'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Rigshospitalet, Denmark', 'class': 'OTHER'}, 'responsibleParty': {'oldNameTitle': 'Kasper Iversen', 'oldOrganization': 'Rigshospitaler'}}}}
