Physiologic assessment has become an essential tool to guide revascularization decisions due to the multiple limitations of angiographic and anatomic measures of physiologic significance. However, in certain cases the apparent physiologic measurement may not accurately reflect the severity of coronary disease compared with anatomical measurements. This article will review how anatomy trumps physiology in cases of acute coronary syndromes, left main disease, saphenous vein graft lesions, and myocardial bridging, and how to overcome the limitations of physiologic measurement in these clinical situations.
