aCoronary artery abnormality suspected by CMR but not present
bHypoplastic left heart syndrome with mitral atresia described intra-operatively by the surgeon (=reference diagnosis). On the CMR performed 8 years later, no mitral atresia was found. Cine sequences confirmed the presence of a hypoplastic but functional mitral valve
cPatent foramen ovale not recognized
dCoronary abnormality (left main stem re-implanted into the non-coronary sinus after Ross operation) not described by CMR
eOstium secundum atrial septal defect not recognized
fDescription of a RV outflow tract aneurysm that was not present
gNon-restrictive ventricular septal defect diagnosed by echocardiography, not recognized
hModified Blalock-Taussig shunt not described on CMR
iUn-operated pulmonary valve described as atretic on echocardiography but considered as severely stenotic valve with hypoplastic pulmonary arteries on CMR
jOperated double outlet RV of Fallot type described as operated tetralogy of Fallot
