Coronary anomaly: anomalous right coronary artery originates from the left sinus of Valsalva and coursing between the pulmonary artery and aorta

Figures & data

Figure 1 (A) RAO caudal view shows a mild lesion in the middle of the LCX artery and (B) LAO view demonstrates no RCA in the right sinus of Valsalva. (C) Reconstructed three-dimensional image obtained by the volume-rendering technique shows the anomalous RCA with an interarterial course. (D) Similarly, the anomalous RCA between the aorta and pulmonary trunk can be seen.

Abbreviations: LAO, left anterior oblique; LCX, left circumflex coronary artery; RAO, right anterior oblique; RCA, right coronary artery.

Figure 2 (A) Reconstructed three-dimensional image obtained using the volume-rendering technique shows the anomalous RCA with an interarterial course. (B) The origin of the anomalous RCA is evident.

Abbreviation: RCA, right coronary artery.

Figure 3 (A) LAO cranial view shows an anomalous RCA arising from the left sinus of Valsalva. (B) LAO cranial view shows a high-grade 90% stenosis in the proximal RCA. (C) LAO cranial view shows a final good angiographic result after PCI procedure. (D) Reconstructed three-dimensional image obtained by the volume-rendering technique shows the anomalous RCA with an interarterial course. (E) The anomalous RCA originates from the left sinus of Valsalva.

Abbreviations: LAO, left anterior oblique; PCI, percutaneous coronary intervention; RCA, right coronary artery.
