PY - 2017 T2 - Interventional Cardiology, 2e AB - Coronary angiography remains the gold standard for imaging coronary anatomy and defining the extent and precise location of coronary artery disease. Optimal coronary angiography is dependent on a thorough knowledge of coronary anatomy and a systematic imaging sequence protocol that enables visualization of all coronary segments, particularly areas of vessel overlap, bifurcations, or tortuous anatomy. A basic map of the coronary anatomy is delineated in Figure 69-1, and the optimal views for imaging each coronary segment are summarized in Table 69-1 (Figs. 69-2, 69-3, 69-4, 69-5). Although standard views are generally consistent from one patient to the next, the precise angulations tend to vary based on the variations in anatomic orientations. A number of coronary segment numbering systems have been established; the most commonly used is the Coronary Artery Surgery Study (CASS) numbering system derived from the Bypass Angioplasty Revascularization Investigation (BARI) study,1 which assigns a unique number to each coronary vessel segment and its branch vessels and has gained wide acceptance in interventional clinical trials (Table 69-2).
