Such a pattern is consistent with significant left main coronary artery stenosis. Angiography done after initial stabilization showed severe stenosis of distal left main coronary artery. ST segment elevation in aVR in proximal LAD occlusion before first septal is thought to be due to transmural ischemia of the basal part of the septum.

Coronary angiography gives a visual impression about the severity of the stenosis. But it need not imply the actual functional significance of the stenosis in terms of flow physiology. indicates inducible ischemia while an FFR above 0.80 excludes ischemia in 90% of cases. identified physiologically significant stenosis.

Transcatheter aortic valve replacement (TAVR) is increasing in popularity for symptomatic severe aortic stenosis. Absence of brachiocephalic artery occlusion which will increase the risk of intraprocedural cerebral ischemia 3. No calcifications in the artery causing vascular stenosis.

In the geometry, the size of the plaque, its relationship to luminal stenosis, arterial remodeling and eccentricity can be evaluated. Transient ischemia may occur while negotiating tight stenosis or small vessels. Plaque morphology assessment with IVUS Plaque morphology can be assessed in terms of its geometry and echogenicity.
