Figure 3

Single coronary artery originating from left sinus of Valsalva (Subgroup 4b). This example illustrates a single coronary artery arising from the left coronary sinus of Valsalva with further intramural proximal course RCA (Image A; Volume Rendering Technique). The axial slice nicely depicts the close proximity of RCA and pulmonary artery (Image B). Again proximal RCA appears elliptical suspicious of lateral compression (Image C1, cross-sectional image) widening up after its intramural course (Image C2, cross-sectional image). Curved Multiplan Reformat shows the common ostium of left main coronary artery and RCA (Image D). DB: diagonal branch, LCX: left circumflex coronary artery, LM: left main coronary artery; LSV: left sinus of Valsalva; PA: pulmonary artery; RCA: right coronary artery.
