Exploring the complexity of congenitally corrected transposition of the great arteries

ultrasound diagnosis and clinical implications - an integrative approach and case report

Abstract

INTRODUCTION: Congenitally corrected transposition of the great arteries (CCTGA) is a rare congenital heart disease that presents challenges in prenatal ultrasound diagnosis. Early and accurate identification of this condition is crucial for treatment planning and proper patient monitoring. OBJECTIVE: This study aims to analyze the challenges of ultrasound diagnosis of CCTGA, highlighting the importance of confirming the occurrence of double atrioventricular and ventriculoarterial discordance for an accurate diagnosis. Additionally, it presents an illustrative case report to exemplify the prenatal echocardiographic diagnosis of this condition. METHODS: An integrative literature review was conducted, with an emphasis on the prenatal ultrasound/echocardiographic diagnosis of CCTGA. Seven articles were selected from a search in the PUBMED and Virtual Health Library databases, using the keywords "corrected transposition of the great arteries" and "prenatal fetal diagnosis." The case report presented in this study was analyzed alongside the selected studies to contribute to the understanding of the challenges in diagnosing this condition. CASE REPORT: The presented case describes a prenatal echocardiographic diagnosis of CCTGA without other associated cardiac abnormalities. It highlights the importance of careful evaluation of routine echocardiographic views to facilitate the accurate diagnosis of this condition. DISCUSSION: The discussion addresses the importance of identifying specific ultrasound markers, such as double atrioventricular and ventriculoarterial discordance, to confirm the diagnosis of CCTGA. Additionally, it discusses the challenges and strategies for early and accurate diagnosis of this condition, especially when found in isolation without other associated cardiac abnormalities. CONCLUSION: The integrative review and case report presented in this study reinforce the importance of careful and systematic prenatal echocardiographic evaluation for the diagnosis of CCTGA. Confirming the occurrence of double atrioventricular and ventriculoarterial discordance is essential for an accurate diagnosis of this condition. Early and correct identification of CCTGA allows for appropriate treatment planning and monitoring of patients affected by this rare congenital heart disease.
