Use of intravascular ultrasound (IVUS) promotes better clinical outcomes for coronary intervention in complex lesions. However, randomized data demonstrating the usefulness IVUS are limited lesions treated with drug-eluting stents.To determine whether long-term IVUS-guided stent implantation superior to those angiography-guided patients long lesions.The Impact Intravascular Ultrasound Guidance on Outcomes Xience Prime Stents Long Lesions (IVUS-XPL) randomized, multicenter trial was conducted...
<h3>Importance</h3> Discontinuing aspirin after short-term dual antiplatelet therapy (DAPT) was evaluated as a bleeding reduction strategy. However, the strategy of ticagrelor monotherapy has not been exclusively in patients with acute coronary syndromes (ACS). <h3>Objective</h3> To determine whether switching to 3 months DAPT reduces net adverse clinical events compared ticagrelor-based 12-month ACS treated drug-eluting stents. <h3>Design, Setting, and Participants</h3> A randomized...
Clinical reads of coronary computed tomography angiography (CTA), especially by less experienced readers, may result in overestimation artery disease stenosis severity compared with expert interpretation. Artificial intelligence (AI)-based solutions applied to CTA overcome these limitations.This study the performance for detection and grading stenoses using artificial intelligence-enabled quantitative (AI-QCT) analyses core lab-interpreted CTA, lab (QCA), invasive fractional flow reserve...
Left atrial (LA) fibrosis is a main determinant of LA remodeling and development fibrillation. However, non-invasive prediction challenging. We investigated whether preoperative strain as measured by speckle tracking echocardiography could predict the degree reverse after mitral valve (MV) surgery.Speckle volume measurements were performed in 50 patients one day before MV surgery. tissues obtained during surgery, degrees their interstitial fibroses measured. repeated within 30 days surgery...
Noninvasive stress testing is commonly used for detection of coronary ischemia but possesses variable accuracy and may result in excessive health care costs. This study aimed to derive validate an artificial intelligence-guided quantitative computed tomography angiography (AI-QCT) model the diagnosis that integrates atherosclerosis vascular morphology measures (AI-QCTISCHEMIA) evaluate its prognostic utility major adverse cardiovascular events (MACE). A post hoc analysis CREDENCE (Computed...
The Genoss paclitaxel-coated balloon (PCB) is a novel PCB with shellac and vitamin E as excipients, enhancing drug delivery to the target lesion minimizing restenosis. This study aimed compare quantitative coronary angiographic outcomes at 6 months after treatment of de novo artery disease (CAD) 2 different types PCBs. prospective, multicenter, noninferiority trial randomized 204 patients chronic syndrome or stabilized acute E-based reference (SeQuent Please NEO) in 1:1 ratio. primary...
The aim of this study was to investigate the combined usefulness platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte (NLR) in predicting long-term adverse events patients who have undergone percutaneous coronary intervention (PCI) with a drug-eluting stent (DES).798 stable angina, unstable angina non-ST elevated myocardial infarction (NSTEMI) underwent elective successful PCI DES were consecutively enrolled. value PLR NLR artery disease (CAD) correlations between these markers...
Coronary artery disease (CAD) is currently the leading cause of death globally, and prevalence this growing more rapidly in Asia-Pacific region than Western countries. Although use metal coronary stents has increased thanks to advancement safety efficacy newer generation drug eluting stent (DES), patients are still negatively affected by some inherent limitations type treatment, such as thrombosis or restenosis, including neoatherosclerosis, obligatory dual antiplatelet therapy (DAPT) with...
Stress imaging has been the standard for diagnosing functionally significant coronary artery disease. It is unknown whether novel, atherosclerotic plaque measures improve accuracy beyond stenosis invasive fractional flow reserve (FFR) measurement.To compare diagnostic of comprehensive anatomic (obstructive and nonobstructive plaque) vs functional estimating vessel-specific FFR.Controlled clinical trial with a multicenter derivation-validation cohort patients referred nonemergent angiography....
P2Y12 inhibitor monotherapy after dual antiplatelet therapy (DAPT; a plus aspirin) for brief duration has recently emerged as an attractive alternative patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stent.
Deep learning frameworks have been applied to interpretation of coronary CTA performed for artery disease (CAD) evaluation.
We compared diagnostic performance, costs, and association with major adverse cardiovascular events (MACE) of clinical coronary computed tomography angiography (CCTA) interpretation versus semiautomated approach that use artificial intelligence machine learning for atherosclerosis imaging-quantitative (AI-QCT) patients being referred nonemergent invasive (ICA).CCTA data from individuals enrolled into the randomized controlled Computed Tomographic Angiography Selective Cardiac Catheterization...
Data on drug-coated balloon (DCB) treatment in the context of diabetes mellitus (DM) and multivessel coronary artery disease (CAD) are limited. We aimed to investigate clinical impact DCB-based revascularization percutaneous intervention (PCI) patients with DM CAD.A total 254 (104 DM) successfully treated DCB alone or combined drug-eluting stent (DES) were retrospectively enrolled (DCB-based group) compared propensity-matched second-generation DES from PTRG-DES registry (n = 13,160 patients)...
ABSTRACT Background There is a paucity of data regarding drug‐coated balloon (DCB) treatment in the context left main (LM) true bifurcation lesions. Aims The aim this study was to evaluate safety and efficacy DCB‐based for unprotected LM Methods A total 39 patients with lesion (Medina: 1,1,1/0,1,1/1,0,1) who were successfully treated DCB alone or combination drug‐eluting stent (DES) retrospectively enrolled into group. They compared propensity‐matched second‐generation DES from COBIS III...
Drug-coated balloon (DCB) treatment is an emerging strategy for de novo coronary artery disease (CAD), but procedural optimization remains uncertain. This study analyzed 317 patients who underwent DCB-based intervention CAD and angiographic follow-up: SR (successful, stent-like result: diameter stenosis < 20% at follow-up angiography, n = 84, 93 lesions) Non-SR (n 224, 358 groups. Baseline clinical lesion characteristics were similar, except that lesions had larger diameter. In lesions,...
Data on drug-coated balloon (DCB) treatment in elderly patients are limited. This study was to evaluate the efficacy of DCB percutaneous coronary intervention (PCI) among patients. A retrospective analysis included 232 aged 75 years or older with artery disease who underwent successful PCI using either alone combination drug-eluting stent (DES) based pre-dilation results (DCB-based PCI). These were compared 1818 second-generation DES implantation (DES-only The endpoint major adverse...
