For either right ventricular volume, the primary effectiveness measure is the % difference between VMS and cMRI results, i.e. (VMS-cMRI)\\*100%/average of VMS and cMRI results. There will be two null hypotheses for the primary analysis:\n\nH0+: true mean % difference \\> 10% and H0-: true mean % difference \\< -10%\n\nThe observed mean % difference will be presented with 95% confidence intervals. The VMS right ventricular volume estimates will be regarded as equivalent to cMRI estimates if both H0+ and H0- are rejected at a 1-sided 0.025 level by a paired t test for both EDV and ESV. Since H0+ and H0- cannot both be true, the total type I error rate for each measure is 0.025 and the overall type I error rate for both EDV and ESV is 0.05.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Primary Care Clinic Cardiac Clinic', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients with Tetralogy of Fallot following surgical repair\n* Patients who can be expected to lie motionless during imaging\n\nExclusion Criteria:\n\n* Lack of informed consent\n* Surgical repair for Tetralogy of Fallot with RV-PA conduit\n* Known arrhythmia that interferes with image acquisition.\n* Implanted cardiac defibrillator, pacemaker, or other devices containing ferromagnetic materials\n* Pregnant woman\n* Contraindications for MRI'}, 'identificationModule': {'nctId': 'NCT01419756', 'acronym': 'VMS TOF', 'briefTitle': 'Assessment of Right Ventricular Volume in Tetralogy of Fallott (TOF) Patients', 'organization': {'class': 'INDUSTRY', 'fullName': 'VentriPoint Diagnostics Ltd.'}, 'officialTitle': 'Assessment of Right Ventricular Volume Using the Ventripoint Medical System in Patients With Tetralogy of Fallott Following Repair; A Comparison Study to cMRI', 'orgStudyIdInfo': {'id': '2011041'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Single Arm', 'description': 'Imaging comparison study.
