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.
Multiple mitral regurgitation jets can be quantified by various methods like quantitative Doppler method, quantitative two dimensional method and PISA method applied to each jet separately.
