Transthoracic echocardiography measurement versus balloon occlusive diameter for atrial septal defect: experience from a Vietnamese cohort (Vietnamese cohort: TTE vs balloon ASD sizing)

Key Points

• Atrial septal defect measurements show notable differences between transthoracic echocardiography and balloon occlusion techniques.
• The study highlights a particular accuracy measure of transthoracic echocardiography as 0.85 versus 0.90 for balloon sizing.
• Observational analysis across a Vietnamese cohort revealed insights into diagnostic accuracy for atrial septal defects.
• These findings suggest that transthoracic echocardiography may enhance pre-procedural sizing, leading to improved patient outcomes.
