Abstract
Percutaneous or surgical coronary revascularization must only be realized if myocardial ischemia is clearly demonstrated. In practice, this ischemia is most often seeked by non-invasive tests. These ones are unfortunately not systematically realized or may bring equivocal results compared to angiographic images. Coronary angiography remains the test of choice for the evaluation of coronary disease, but visual analysis of coronary stenosis does not confirm their hemodynamic significance. The measurement of coronary flow reserve by FFR ("fractional flow reserve") or iFR («instantaneous wave-free ratio») is a simple method to invasively assess the hemodynamic impact of a coronary lesion. Spastic angina, when suspected by clinical history, can also be confirmed during coronary angiography by the provocative methylergonovine test.
