Anomalous Origin of the Left Coronary System From the Right Coronary Cusp: A Case Report

Figures

• 

  FIGURE 1. Coronary angiogram with evidence of common origin of the right and left systems from the right aortic sinus and obstructive coronary artery disease with 99% proximal LCX stenosis. Notice also diffused coronary artery disease in the RCA. Notice also how the LAD crosses horizontally at a 90‐degree angle to the catheter that engaged the RSV. LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery; RSV, right sinus of Valsalva.

  FIGURE 2. (A, B) CT heart with tridimensional reconstruction of the coronary artery system. LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery; RSV, right sinus of Valsalva.

• 

  FIGURE 3. Coronary angiogram after successful PCI in the proximal LCX with TIMI 3 flow. Notice more clearly how the LAD crosses the engaging catheter in a horizontal fashion. LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery; RSV, right sinus of Valsalva.
