Defining the coronary artery anatomy is a critical step in any evaluation of ischemic heart disease and developing a treatment plan for your patient.

The location of atherosclerotic lesions can be suggested by provocative stress testing (exercise or pharmacologic stress, and multiple evaluation modalities including ECG, echocardiography, and nuclear medicine). However, definitive identification can only be accomplished by either left heart catheterization or CT coronary angiogram. While there are benefits to both tests, catheterization defines lesions geometrically and functionally, and during the same procedure allow intervention (PCI) if indicated.

The coronary anatomy is complex and varies significantly between patients (eg. <
