Overview

Invasive Coronary Angiography (ICA) is used to determine the presence and severity of a luminal obstruction of an epicardial coronary artery, including its location, length, and diameter, as well as coronary blood flow. ICA provides the characterization of high-grade obstructive stenosis and possibility for percutaneous or surgical revascularization. (IFR and FFR) provide physiologic characteristic of stenosis. Radiation exposure to the patient during an interventional procedure varied 4 to 10 mSv and is dependent on procedural duration and complexity. The spatial resolution of ICA is 0.3 mm; as such, it is impossible to visualize arterioles (diameter of 0.1 mm) that regulate myocardial blood flow. Coronary vascular functional studies can be performed during coronary angiography. In normal coronary angiography there may be evident abnormal coronary vascular function. Assessment of coronary microcirculation and coronary vasomotion by coronary function testing are reasonable.
