Evidence-Based Practices in the Cardiac Catheterization Laboratory: Invasive Epicardial Coronary Physiologic Assessment: A Scientific Statement From the American Heart Association

Invasive epicardial coronary physiologic assessment is increasingly performed to evaluate the hemodynamic significance of intermediate coronary lesions and is recommended by guideline committees. Whereas much of the practice in coronary physiologic assessment is based on evidence, some non–evidence-based traditions and misconceptions persist. The aim of this review is to highlight evidence-based practice in invasive epicardial coronary physiologic assessment and to refute or validate common elements of clinical practice.
