Objectives: The present study sought to determine whether optical coherence tomography (OCT) guidance results in a degree of stent expansion comparable to that with intravascular ultrasound (IVUS) guidance.
Objectives: This study sought to investigate the clinical outcomes based on the assessment of quantitative coronary angiography–maximal lumen diameter (Dmax).
Objectives: The aim of this study was to evaluate a strategy of intentional underexpansion of excessively oversized balloon-expandable transcatheter heart valves (THVs) in terms of clinical outcomes, valve function, and frame durability at 1 year.
Objectives: We report our 8-year experience in transcatheter aortic and mitral valve-in-valve (VinV) implantation.
Objectives: The aim of this study was to determine the incidence, causes, and predictors of unplanned hospital readmissions after transcatheter aortic valve replacement (TAVR).
A 53-year-old man presenting with stable angina underwent coronary angiography demonstrating a critical true bifurcation lesion (Medina 1,1,1) of the left anterior descending coronary artery (LAD). Following pre-dilation, a 3.5 × 18-mm Absorb (Abbott Vascular, Santa Clara, California) bioresorbable scaffold (BRS) was implanted in the LAD with subsequent 3.5-mm high-pressure noncompliant balloon post-dilation.
Aims: Initial thrombolysis in myocardial infarction (TIMI) flow and mortality are related in ST-elevation myocardial infarction (STEMI) patients treated with primary angioplasty (PPCI). It is unclear whether early adjunctive treatment with unfractionated heparin (UFH) is beneficial for coronary patency. We investigated the effect of UFH administered before transfer versus in the catheterization laboratory (CathLab) on initial patency of the infarct related artery (IRA) in transferred STEMI patients treated with PPCI.
Introduction: Women with acute myocardial infarction are treated less aggressively than men and have a higher mortality. It is possible that these sex-related differences in outcome are a result of differences in baseline risk and management.
Background: The long-term prognostic value of the computed tomography (CT)-based SYNTAX score has not yet been investigated. The aim of our study was to investigate the prognostic value of the CT-SYNTAX score in predicting major adverse cardiac events (MACEs) in populations who underwent both coronary computed tomography (CCTA) and invasive coronary angiography (ICA), compared with prognostic values of coronary artery disease (CAD) findings on CCTA and the ICA-based SYNTAX score.
Objectives: This study assessed whether different subsets of circulating endothelial and putative endothelial progenitor cells (CEC and EPC) correlate with stent strut coverage (SSC) using second generation optical coherence tomography (OCT).
Background: The influence of antiplatelet therapy discontinuation on the incidence of stent thrombosis, especially very late stent thrombosis, after drug-eluting stent implantation has not been yet fully addressed.
Background: The management and impact of concomitant coronary artery disease in patients referred for TAVI remains contentious. We describe the prevalence, clinical impact and management of coronary artery disease (CAD) in patients in the United Kingdom TAVI Registry.
Background: Despite common use of second-generation drug-eluting stents in treating patients with coronary artery disease, there is lack of data comparing these stents exclusively in patients with acute myocardial infarction (AMI), especially with metabolic syndrome (MetS), which is highly prevalent in AMI and potential to worsen clinical outcomes. The aim of this study was to compare clinical outcomes of everolimus-eluting stent (EES) and Resolute-zotarolimus-eluting stent (R-ZES) in AMI patients with MetS, in terms of stent-related and patient-related outcomes.
Background: The instantaneous wave-free ratio (iFR) is a new adenosine-independent index of coronary stenosis severity. Most published data have been based on off-line analyses of pressure recordings in a core laboratory. We prospectively compared real-time iFR and fractional flow reserve (FFR) measurements.
Background: Myocardial CT perfusion (CTP) has been validated as an incremental diagnostic predictor over coronary computed tomography angiography (CTA) in assessing hemodynamically significant stenosis.
