Plaque morphology predictors of side branch occlusion after provisional stenting in coronary bifurcation lesion: Results of optical coherence tomography bifurcation study (ORBID).

The aim of this study was to identify the predictors of side branch (SB) ostial stenosis developed after provisional stenting of the main vessel (MV) using optical coherence tomography (OCT).

Three Dimensional Volumetric Assessment of Coronary Artery Calcification in Patients with stable Coronary Artery Disease by OCT.

AIMS There is a lack of a reliable technique to quantify coronary artery calcification (CAC). Hence, we used optical coherence tomography (OCT) to quantitate three-dimensional CAC volume to examine its association with plaque characteristics. METHODS AND RESULTS A total of 250 patients with stable angina undergoing OCT imaging before PCI were included. CAC volume was calculated from every frame of the culprit lesion and divided into tertiles (low, intermediate and high). Quantitative calcium characteristics were assessed in 107 patients who underwent both OCT and IVUS. Increase in CAC volume was associated with reduced lipid volume index, lipid length and number of lipid plaques. Diabetes and LDL cholesterol predicted less coronary calcification whereas age and prior MI predicted increased CAC after adjusting for all clinical factors. Lipid volume index (ρ=-0.001 [-0.003 to -0.00003]; p=0.04) and mean calcium depth (ρ=-0.02 [-0.02 to -0.01]; p=0.000) were inversely related to CAC volume after adjusting for all OCT characteristics, whereas cap thickness increased with increase in CAC volume (ρ=0.01 [0.002-0.03]; p=0.02) only in unadjusted analysis. Regression analysis demonstrated a significant correlation between calcium length (ρ=0.83; p<0.001) and calcium arc (ρ=0.86; p<0.001) measured by IVUS and OCT. CONCLUSIONS Target lesions with high CAC volume are characterised by reduced plaque lipid content and calcium closer to the luminal border. Fibrous cap thickness increased with increase in calcium volume.

PLAQUE MORPHOLOGY PREDICTORS OF SIDE BRANCH OCCLUSION AFTER MAIN VESSEL STENTING IN CORONARY BIFURCATION LESION: OPTICAL COHERENCE TOMOGRAPHY IMAGING STUDY

There is little information about underlying plaque morphology of the main vessel (MV) and its potential impact on side branch occlusion (SBO) after MV stenting. 116 consecutive coronary bifurcations with side branch (SB) >1.5mm undergoing provisional SB stenting were analyzed. Optical coherence

Prevalence, correlates, and impact of coronary calcification on adverse events following PCI with newer‐generation DES: Findings from a large multiethnic registry

We sought to determine the prevalence, predictors, and clinical impact of target lesion calcification in patients undergoing percutaneous coronary intervention (PCI) with newer generation drug‐eluting stents (DES) and devices.

Plaque Morphology Predictors of Side Branch Occlusion After Main Vessel Stenting in Coronary Bifurcation Lesions: Optical Coherence Tomography Imaging Study.

Side branch (SB) occlusion remains a major complication of bifurcation lesion treatment. Although plaque and carina shift are suggested as mechanisms of SB occlusion [(1)][1], little is known about underlying plaque morphology and composition of the main vessel (MV) and its potential impact on SB

TCT-163 Do Patients with Paroxysmal Atrial Fibrillation in Sinus Rhythm during PCI Require Triple Therapy? Results from a Multicenter Center Study

Paroxysmal atrial fibrillation (AF) is frequent in patients undergoing percutaneous coronary intervention (PCI), but optimum antithrombotic therapy has not been defined, and whether patients with paroxysmal AF in sinus rhythm (SR) at the time of PCI require anticoagulation concurrent with DAPT is
