A case of coronary artery disease with moderate stenoses in the proximal left anterior descending artery, the middle segment of the right coronary artery and at the ostium of the dominant ramus intermedius in the setting of a quadrifurcation of the left main stem.

This case demonstrates that different image reconstruction algorithms can clarify or obscure findings and artifacts depending on the chosen algorithm. Edge correction can help to create more beautiful 3D reconstructions in a prospective gated coronary CTA by covering up stair-step artifacts. On the other hand, image reconstruction without edge correction can clarify findings and artifacts created by the correcting algorithm.

According to the 2.0 version of the Coronary Artery Disease - Reporting and Data System ² this case is classified CAD-RADS 3/P4.

Management recommendations include functional assessment to look for signs of myocardial ischemia ^2,3 as well as aggressive risk factor modification and preventive therapy ².
