Reversible Regional Myocardial Ischemia in a Six-Month-Old Infant Post Arterial Switch Operation Demonstrated by Speckle Tracking Echocardiography

Mini‐ We present the case of an infant with coronary artery stenosis following an arterial switch operation for transposition of the great arteries. He was demonstrated to have reversible regional myocardial ischemia using speckle tracking echocardiography (STE), which corresponded to the affected t...

Summary:Mini‐ We present the case of an infant with coronary artery stenosis following an arterial switch operation for transposition of the great arteries. He was demonstrated to have reversible regional myocardial ischemia using speckle tracking echocardiography (STE), which corresponded to the affected territory seen when he underwent cardiac catheterization with revascularization. This demonstrates the utility of STE in infants with regional myocardial dysfunction.
