Echocardiographic evaluation in transposition of the great arteries in the adult

Area of Science:

• Cardiology
• Medical Imaging
• Pediatric Cardiology

Background:

• Transposition of the great arteries (TGA) is a congenital heart defect characterized by ventriculo-arterial discordance.
• TGA presents in two distinct subtypes, requiring specific diagnostic approaches.
• Adult evaluation of TGA often relies on non-invasive imaging modalities.

Purpose of the Study:

• To outline the essential echocardiographic elements for evaluating adults with TGA.
• To emphasize echocardiography's role as the primary diagnostic tool for TGA in this population.
• To detail key echocardiographic findings indicative of TGA and its associated complications.

Main Methods:

• Echocardiography is the principal imaging modality employed.
• The examination focuses on confirming the diagnosis of TGA.
• Assessment includes ventricular morphology, function, valvular integrity, baffle patency, and shunt detection.

Main Results:

• Echocardiography effectively confirms the diagnosis of ventriculo-arterial discordance.
• The exam allows for comprehensive evaluation of ventricular size and systolic/diastolic function.
• Assessment identifies critical elements such as valvular regurgitation, baffle leaks, and residual shunts.

Conclusions:

• Echocardiography is indispensable for the comprehensive evaluation of adult TGA.
• Key echocardiographic assessments include ventricular function, valvular status, and baffle integrity.
• Ruling out residual shunts and estimating pulmonary artery pressures are vital components of the exam.
