Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Occlusion of large side branches (SBs) may result in significant adverse clinical events 4. Occlusion of jailed sizable septal and right ventricular (RV) side branches (non-classic bifurcations) is often overlooked following left anterior descending (LAD) and right coronary artery (RCA) main vessel stenting, respectively. Most of the operators decline intervening in these side branches on contrary to classic bifurcations as diagonals and obtuse marginal branches, for example. Whether or not intervening with these occluded jailed side branches have clinical implications or even sub clinical left ventricular (LV) dysfunction was not previously elucidated and warrants studying.
Left ventricular function is an important predictor of outcome in patients with coronary artery disease (CAD). Extensive myocardial ischemia can cause decreased LV contractility and function 5. Conventional echocardiography enables us to identify significant left ventricular dysfunction but not sub-clinical dysfunction \[10\]. Two-dimensional speckle tracking echocardiography (2D-STE) allows for an angle-independent evaluation of myocardial strain, and provides comprehensive information on LV myocardial contractility. Thus, 2DSTE is superior in detecting subtle deterioration of contractility 6 .
In this study, investigators tried to explore the possible predictors and outcomes following occlusion of jailed side branches after main vessel coronary artery stenting, in both classic and non-classic bifurcations, and whether intervening via various techniques would have clinical benefit.

2D-speckle tracking echocardiography
Two-dimensional speckle tracking echocardiography (2D-STE) allows for an angle-independent evaluation of myocardial strain, and provides comprehensive information on LV myocardial contractility. Thus, 2DSTE is superior in detecting subtle deteriorations of contractility. we will take 2D speckle tracking views for LV and RV strain (4ch, 2ch, 3ch, RV modified view).
