Evaluation of myocardial perfusion and viability in coronary artery disease in view of the new revascularization guidelines

Abstract

Evaluation of myocardial perfusion and viability in patients with stable coronary artery disease have now become the basic source of information in qualification for revascularization or optimal medical therapy. This article describes all the available methods of non-invasive imaging of myocardial perfusion and viability.

“…Myocardial perfusion imaging (MPI) is a useful non-invasive tool to determine whether there is a myocardial perfusion defect. 4 …”

The Clinical Impact of CTO Recanalization

“…At the present time, there are no contemporary randomized trials comparing revascularization to medical therapy in stable patients with isolated LAD disease. Accordingly, clinical recommendations are built on extrapolation from trials comparing medical therapy with revascularization in patients with multivessel disease and a large area of myocardium at risk or significant left ventricular dysfunction . As the LAD is responsible for the perfusion of almost 70% of the left ventricular mass, its compromise (acute or silent) virtually always benefits from revascularization.…”

“…As the LAD is responsible for the perfusion of almost 70% of the left ventricular mass, its compromise (acute or silent) virtually always benefits from revascularization. Regardless of the targeted vessel segment, revascularization should be preferred to medical therapy in patients with large amount of viable myocardium at risk .…”
