Background— Despite the enhanced properties of second-generation drug-eluting stent (DES), its association with neoatherosclerosis has not been sufficiently evaluated. Therefore, we sought to evaluate and compare in DESs first-generation DESs. Methods Results— A total 212 DES-treated patients >50% percent neointimal cross-sectional area stenosis were retrospectively enrolled from Korean multicenter optical coherence tomography (OCT) registry. Within this population, 111 had a DES (40...
Current guidelines recommend the perioperative continuation of aspirin in patients with coronary drug-eluting stents (DES) undergoing noncardiac surgery. However, supporting evidence is limited.
Inflammation plays a pivotal role in the pathogenesis of acute coronary syndrome. Detecting plaques with high inflammatory activity and specifically treating those lesions can be crucial to prevent life-threatening cardiovascular events.
To use optical coherence tomography (OCT) to evaluate the time course, risk factors, and clinical implication of in-stent neoatherosclerosis.The neointimal characteristics 152 lesions, 128 drug-eluting stents (DESs) 24 bare metal (BMSs), with >50% percent cross-sectional area (CSA) stenosis were evaluated. Neoatherosclerosis was defined as neointima presence lipid or calcification. observed in 54 lesions (35.5%, 35 DESs 19 BMSs). Median follow-up 70.7 months neoatherosclerosis (longer than...
Objective To evaluate whether the association of obesity with coronary atherosclerosis depends on risk cardiovascular disease (CVD). Methods A total 1,406 asymptomatic Korean adults underwent both cardiac and abdominal multislice computed tomography (MSCT) as part a routine health check‐up. Obesity was measured using body mass index (BMI), waist circumference (WC), MSCT‐derived area/ratio visceral subcutaneous fat. The burden CVD assessed by Framingham equation. Results In low‐risk group for...
Background The pathophysiology underlying very late drug‐eluting stent ( DES ) thrombosis is not sufficiently understood. Using optical coherence tomography, we investigated characteristics of VLST according to different onset times. Methods and Results A total 98 patients from 10 South Korean hospitals who underwent tomography for evaluation were retrospectively included in analyses. occurred at a median 55.1 months after implantation. All divided into 2 equal groups earlier versus delayed...
Background The effects of severe acute stent malapposition ( ASM ) after drug‐eluting implantation on long‐term clinical outcomes are not clearly understood. We evaluated using optical coherence tomography. Methods and Results pooled patient‐ lesion‐level data from 6 randomized studies. Five studies investigated follow‐up strut coverage one . In this set, a total 436 patients with 444 lesions underwent postintervention tomography examination these were included in the analysis. Severe was...
Background There is a lack of data on factors that are related to clinically relevant bleeding after ticagrelor treatment. We investigated the clinical and procedural major in patients with acute coronary syndrome treated stent implantation. Methods Results From TICO (Ticagrelor Monotherapy After 3 Months Patients Treated With New Generation Sirolimus-Eluting Stent for Acute Coronary Syndrome) randomized trial, total 2660 were included present study. bleeding, defined by TIMI (Thrombolysis...
Background Despite the clinical benefits to intravascular ultrasound (IVUS) guidance for percutaneous coronary intervention (PCI), most patients with artery disease undergo angiography‐guided PCI alone in real‐world setting. We sought investigate procedural characteristics of IVUS‐guided and their outcomes, as compared PCI. Methods Results This was a cohort study using patient‐level data from IVUS‐XPL (Impact Intravascular Ultrasound Guidance on Outcomes Xience Prime Stents Long Lesions)...
Entrapment of a guidewire is rare event, but it could happen especially in severe calcified stenotic lesion. This complication life-threatening because can lead to myocardial ischemia, infarction, or lethal arrhythmia due intracoronary thrombosis. In the event failed retrieval and persistent signs patients should be urgently referred surgery. During percutaneous coronary intervention, Tornus catheter has been applied with artery disease when balloon microcatheter cannot crossed across lesion...
The assessment of fractional flow reserve (FFR) in coronary lesions determines the strategy percutaneous intervention. However, association between FFR and characteristics underlying plaque has not been sufficiently investigated.A total 110 106 patients were evaluated using both optical coherence tomography (OCT). Coronary plaques classified into fibrous, fibrocalcific, or fibroatheroma according to OCT evaluation at site minimal lumen area. Plaque microstructures such as cap thickness,...
