Overview
Incomplete great vessel transposition involves an abnormal arrangement of the aorta and pulmonary artery, often leading to cyanosis and hypoxemia due to mixing of systemic and pulmonary circulations. 1Diagnosis
Clinical Presentation: Cyanosis, tachypnea, and signs of heart failure in neonates. 1
Echocardiography: Essential for confirming the diagnosis, assessing anatomy, and guiding management decisions. 1
Telemedicine Utilization: Effective for remote screening and initial diagnosis, facilitating timely transfer to specialized centers. 1Management
Prostaglandin E1: Maintained patency of the ductus arteriosus to ensure adequate systemic and pulmonary blood flow. 1
Surgical Correction: Anatomical repair, typically performed within the first few weeks of life, often involving an arterial switch operation. 1
Postoperative Care: Close monitoring for complications, including arrhythmias and right ventricular dysfunction. 1Special Populations
Pediatrics: Early diagnosis and intervention via telemedicine networks improve outcomes in underserved areas. 1Key Recommendations
Utilize telemedicine for remote echocardiography and initial management in underserved regions to expedite referral to specialized centers. (Evidence: Expert opinion) 1
Administer prostaglandin E1 to maintain ductal patency in neonates with incomplete great vessel transposition until surgical correction. (Evidence: Expert opinion) 1
Perform anatomical correction surgery within the neonatal period to optimize outcomes and minimize morbidity. (Evidence: Expert opinion) 1References
