Restenosis in BMS is more diffuse and severe and difficult to tackle with drug eluting balloon. Focal lesions are seen with SES, diffuse lesions in PES.

Bifurcation lesions have wide range of variations in plaque burden, plaque location, site of bifurcation, angle between branches and diameter of branches.

Optical coherence tomography (OCT) has higher resolution of 10 - 20 microns, but tissue penetration is only 2 - 3 mm, compared to 10 mm for IVUS.

Functional SYNTAX score is calculated using data from coronary angiography and fractional flow reserve (FFR).

Intracardiac echocardiography allows excellent resolution images as high frequency transducers can be used in close proximity to structures being imaged.

Balloon atrial septostomy is classic bail out procedure for the deeply cyanosed and acidotic newborn with d-TGA and poor admixture.

SYNTAX score is a scoring system for coronary lesions based on the online calculator available at www.syntaxscore.com.

Stent was superior to balloon angioplasty and surgery was superior to stent in coarctation of aorta, but with longer hospital stay.

PCI in CAD associated with severe aortic stenosis could be performed no significant increased risk of short term mortality.

Polymer free amphilimus stent has lower in stent late lumen loss and better 1 year clinical safety and efficacy in treatment of de novo coronary lesions.
