“…8 -10 The coronary arteries in children treated with ASO for TGA are surgically relocated to the aortic root, and this may cause coronary flow abnormalities, even late after the operation. 1,2,11 Myocardial perfusion defects found in asymptomatic survivors of the ASO have raised further concerns regarding the long-term function and patency of the coronary arteries in this patient group, recently supported by myocardial PET studies revealing reduced global myocardial CFR. 4,6,12 Documented cases of true myocardial ischemia or sudden death in this patient group have however been exclusively associated with anatomic coronary stenosis.…”

Background-Recent studies performed with positron emission tomography have suggested that coronary flow reserve (CFR) is moderately to severely reduced after the arterial switch operation (ASO). These findings are of great concern but have not been confirmed by other methods. Methods and Results-Eleven symptom-free children were studied between 4 and 11 (median 6.0) years after the ASO.Flow velocity in the left anterior descending (LAD) and right coronary arteries (RCA) was measured with a 0.014-inch Doppler FloWire (Cardiometrics) before and after intracoronary injection of adenosine (0.5 g/kg) and nitroglycerin (5 g/kg). CFR was defined as the ratio of hyperemic to basal average peak velocity (APV). The median (range) CFR in the LAD was 3.7 (3.0 to 4.8) and 3.4 (2.9 to 4.8) in the RCA. The increase in APV after intracoronary injection of nitroglycerin was 300% (240% to 420%) in the LAD and 260% (190% to 460%)

“…Although long-term survival has been excellent, follow-up studies have revealed a significant prevalence (3% to 7.8%) of coronary stenosis and occlusions, even occurring in symptom-free subjects. 1,2 Data on the function of the coronary arteries after the ASO are limited, however.…”

Increasing numbers of adults with congenital heart disease are referred for cardiac magnetic resonance imaging. Knowledge of the congenital heart anatomy, prior surgical interventions, and the development of an imaging focus for each individual patient plays a crucial role when performing a successful cardiac magnetic resonance imaging examination. The following manuscript focuses on cardiac magnetic resonance imaging considerations of three specific conotruncal congenital heart lesions: tetralogy of Fallot, transposition of the great arteries (TGA), and physiologically corrected TGA (c-TGA).

“…Mid-term follow-up is greatly influenced by coronary events after the Jatene procedure, as demonstrated in several studies (table III), where coronaryangiographies show them to occur in 3 to 11% of the cases during a 5-year follow-up after the surgery, with a mortality rate ranging from 0 to 10% [2][3][4][5][6] .…”

“…Complications from these pre-existing factors or resulting from the technique itself are mainly represented by ventricular failure, coronary events, right ventricular outflow tract obstruction, and regurgitation of the new aortic valve [2][3][4][5][6][7] .…”
