Ischemia guided myocardial revascularization is important when myocardial revascularization is undertaken in the absence of significant symptoms.

Coronary angiogram still shot showing stenosis of RCA and PDA (right coronary artery and posterior descending coronary artery)

Coronary angiogram showing total occlusion of mid LAD (left anterior descending coronary artery)

Coronary artery perforation is an important, rare complication of PCI. Perforations can be caused by guide wires, angioplasty balloons or rotablator burr.

Transvenous IVUS guided PCI for CTO is a novel technique in which the IVUS catheter is introduced through the cardiac vein parallel to the target artery

Limited antegrade subintimal tracking (LAST) is technique used for crossing chronic total occlusions (CTO) with a guide wire prior to balloon angioplasty

J-CTO score for prediction of wire crossing in CTO (chronic total occlusion) of native coronary arteries in 30 minutes from multi centre CTO registy of Japan

Polygon of confluence in IVUS is confluence of left main coronary artery (LMCA), left circumflex (LCX) and left anterior descending (LAD) coronary artery

Proximal optimisation technique (POT) is post dilatation of the proximal portion of the stent in the main vessel, done after kissing balloon dilatation in bifurcation lesions.

Coronary guide catheter and PTCA balloon inflation at OM lesion Inflation of PTCA balloon positioned across the stenosis of obtuse marginal branch of the left circumflex coronary artery.
