Key result
Coronary CT angiography detected unfavourable coronary abnormalities in 60% of asymptomatic patients after an arterial switch operation, which could not be predicted by other non-invasive tests.
Why the study?
There is no consensus regarding the need, indications, or best first-line modality for routine long-term follow-up coronary artery evaluation after an arterial switch operation.
Does routine non-invasive screening predict potentially dangerous coronary patterns detected by coronary CT angiography in asymptomatic patients with transposition of the great arteries after an arterial switch operation?
Population
50 consecutive asymptomatic patients after an arterial switch operation
Design
Single-center observational study

Noninvasive screening fails to identify high-risk coronary anatomy post-ASO; leaves open whether routine CTA improves outcomes in asymptomatic TGA patients.

Does routine non-invasive screening predict potentially dangerous coronary patterns detected by coronary CT angiography in asymptomatic patients with transposition of the great arteries after an arterial switch operation?
In asymptomatic patients after an arterial switch operation for transposition of the great arteries, potentially dangerous coronary abnormalities are common (60%) and cannot be predicted by standard non-invasive screening, supporting the use of routine coronary CT angiography.
Michalak et al. (2019) conducted an observational in Transposition of the great arteries after an arterial switch operation (n=50). Coronary CT angiography was evaluated on Unfavourable coronary abnormalities. Coronary CT angiography detected unfavourable coronary abnormalities in 60% of asymptomatic patients after an arterial switch operation, which could not be predicted by other non-invasive tests.
