Medical treatments to promote regeneration of new healthy heart muscle cells have the potential to provide new heart failure treatments for these patients. The development of such therapies is limited by the poor understanding of the ways in which heart muscles grow after birth. Investigators have learned that humans without heart disease generate new heart muscles cells up to the age of 20 years old and that this is decreased in patients with congenital heart disease like Tetralogy of Fallot. Investigators are trying to determine if treatment with a medicine called Propranolol can increase heart muscle cell proliferation and, with that, normalize heart growth. Investigators will examine discarded heart muscle tissue that is obtained during surgery for the presence of new heart muscle cells. Propranolol is approved by the Food and Drug Administration (FDA) to treat a certain kind of benign tumor in infants (hemangioma), but it is not currently approved by the FDA to increase heart muscle growth.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '60 Days', 'minimumAge': '30 Days', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Male and female infants \\< 60 days of age with a diagnosis of tetralogy of Fallot (ToF) with pulmonary stenosis (PS) or double outlet right ventricle (DORV), tetralogy type by echocardiogram, who weigh greater than 2 kg at the time of consent and are tolerating enteral feeds.\n* DORV variant\n\nExclusion Criteria:\n\n* congenital atrio-ventricular block on EKG (PR interval \\> 120 ms),\n* concomitant medication administration that interacts with propranolol,\n* patient family is, in the opinion of the investigator, unable to comply with the requirements of the study protocol or is unsuitable for the study for any reason,\n* gestation age \\< 35 weeks,\n* infants of diabetic mothers, asthma or underlying respiratory disease,\n* presence of metal implants in infants.'}, 'identificationModule': {'nctId': 'NCT04713657', 'briefTitle': 'Beta-blocker Administration for Cardiomyocyte Division', 'organization': {'class': 'OTHER', 'fullName': 'Weill Medical College of Cornell University'}, 'officialTitle': 'Mechanistic Clinical Trial of Beta-Blocker Administration For Reactivating Cardiomyocyte Division In Tetralogy of Fallot', 'orgStudyIdInfo': {'id': '23-12026881'}, 'secondaryIdInfos': [{'id': 'R01HL155597', 'link': 'https://reporter.nih.gov/quickSearch/R01HL155597', 'type': 'NIH'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Propranolol', 'description': 'The target dose of Propranolol hydrochloride for this study target dose for this study will be 4 mg/kg/day divided in 4 doses.
