Confirmation of Anomalous Origin of the Right Coronary Artery From the Left Sinus of Valsalva With Magnetic Resonance Imaging

Magnetic Resonance Imaging of the Myocardium, Coronary Arteries, and Anomalous Origin of Coronary Arteries

“…Machado and colleagues [ 284 ] were probably the fi rst to report the use of MRI to visualize an anomalous RCA with T 1 spin-echo sequences. McConnell and associates [ 285 ] used 3D breath-hold, ECGgated, segmented k-space, gradient-echo sequences to evaluate 15 patients with CAAs.…”

Anomalous origin of right coronary artery: Magnetic resonance angiography and viability study

“…We used a commercially available inversion recovery prepared-, electrocardiographically triggered-, fast gradient recalled-echo pulse sequence with echo time 2 to 3.5 ms; repetition time 5.5 to 7.6 ms; inversion time, 100 -350 ms; flip angle, 20; field of view, 170 to 350 mm; matrix, 192 Â 256; slice thickness, 6 to 8 mm; and signal averages 0.5 to 1 (17,18). Inversion times were adjusted to null normal myocardium with voxel sizes of 1.7 Â 1.4 Â 8.0 mm.…”

Noninvasive imaging of anomalous coronary arteries

“…Second, MR coronary angiography could distinguish an occluded vessel from an anomalous one in cases in which a vessel cannot be engaged by conventional angiography. Finally, it could potentially be used in young patients with unexplained syncope or chest discomfort in whom a coronary anomaly is the part of the differential diagnosis [30][31][32]. From all techniques available, 2D breathhold coronary MR angiography, 3D retrospective respiratory navigator-gated coronary MR angiography, and breathhold 3D coronary MR angiography have been evaluated clinically [33][34][35][36][37][38][39].…”
