A Combination of Two Rare Coronary Anomalies Makes It Even Rarer: Right Sided Single Coronary Artery with Dual Left Anterior Descending Artery

Figure 1

Coronary angiographic image (left anterior oblique 30°/0° projection, field of view 25 cm²) showing single coronary artery (SCA) arising from the right sinus of Valsalva as short common trunk which divides into right coronary artery (RCA) and left main coronary artery (LMCA). LMCA further bifurcates into the proximal left anterior descending (LAD) artery and the circumflex (Cx) artery. The distal LAD originates separately from the right coronary artery. Stenotic lesions in right posterolateral (RPL) and right posterior descending (RPD) arteries are also depicted.
