Objectives: The aim of this study was to assess the volume–outcome relationship for PCI within the nationwide registration system in Japan.
Objectives: The authors sought to compare the diagnostic performance of fractional flow reserve (FFR), instantaneous wave-free ratio (iFR), and resting distal coronary artery pressure/aortic pressure (Pd/Pa) using 13N-ammonia positron emission tomography (PET).
Objectives: The authors sought to analyze height differences within the coronary artery tree in patients in a supine position and to quantify the impact of hydrostatic pressure on intracoronary pressure measurements in vitro.
Objectives: The purpose of this study was to evaluate the economic impact of the Absorb bioresorbable vascular scaffold compared with the Xience everolimus-eluting stent in patients undergoing percutaneous coronary intervention.
Objectives: This study investigated the vasomotor response to nitroglycerine (NTG) up to 5 years after ABSORB implantation.
Objectives: This study sought to use a new catheter technique to split the anterior mitral valve leaflet (AML) and prevent iatrogenic left ventricular outflow tract (LVOT) obstruction immediately before transcatheter mitral valve replacement (TMVR).
Objectives: The aim of the study was to investigate the influence of the extent of computed tomography (CT)–based area and perimeter oversizing on the incidence and severity of paravalvular aortic regurgitation (PAR) for the Edwards SAPIEN 3 (Edwards Lifesciences, Irvine, California) device, using CT data and echocardiographic outcome data of the PARTNER II (Placement of AoRTic TraNscathetER Valves Trial II) SAPIEN 3 intermediate-risk cohort.
Background: Second-generation drug eluting stents (DES) may reduce costs and improve clinical outcomes compared to first-generation DES with improved cost-effectiveness when compared to bare metal stents (BMS). We aimed to conduct an economic evaluation of a cobalt-chromium everolimus eluting stent (Co-Cr EES) compared with BMS in percutaneous coronary intervention (PCI).
We report a new technique for treatment of radial artery pseudoaneurysm (RAP) caused by transradial access (TRA) for coronary angiography. Traditional extrinsic compression with radial flow cessation leads to a local milieu likely associated with an increase in probability of radial artery occlusion (RAO). Our technique involves obtaining ipsilateral radial artery access distal to the neck of the RAP followed by a prolonged sheath dwell time covering the neck of the RAP which allows the RAP sac to thrombose and maintains radial artery lumen patency.
Background: The performance of emerging transcatheter aortic valve implantation (TAVI) clinical prediction models (CPMs) in national TAVI cohorts distinct from those where they have been derived is unknown. This study aimed to investigate the performance of the German Aortic Valve, FRANCE-2, OBSERVANT and American College of Cardiology (ACC) TAVI CPMs compared with the performance of historic cardiac CPMs such as the EuroSCORE and STS-PROM, in a large national TAVI registry.
Background: Identifying predictors of coronary artery disease (CAD)-related procedures and events remains a priority.
Background: Optimal antithrombotic treatment after transcatheter aortic valve replacement (TAVR) is unknown and determined empirically. The direct factor Xa inhibitor rivaroxaban may potentially reduce TAVR-related thrombotic complications and premature valve failure.
Background: Patients with atrial fibrillation (AF) are prone to cardiovascular events and anticoagulation-related bleeding complications. We hypothesized that patients with anemia are at increased risk for these outcomes.
Background: Cardioversion is a class I procedure for patients with symptomatic atrial fibrillation (AF) pursuing rhythm control. There are few contemporary reports on quality of life and outcomes after cardioversion.
Aims: What the best strategy is for nonculprit lesions in ST-elevation myocardial infarction (STEMI) patients presenting with multivessel disease remains a clinical dilemma. Based on recent clinical studies suggesting that complete revascularization in the acute phase is beneficial, the European Society of Cardiology and American College of Cardiology/American Heart Association guidelines have been recently changed from class 3 discouragement to a class 2B recommendation concerning the treatment of the nonculprit lesions in the acute index procedure. However, in these recent studies, nonculprit lesion treatment was guided by angiography, which is known for its poor accuracy in determining ischemia. Fractional flow reserve (FFR) guidance for treatment of nonculprit vessels seems to be a reasonable approach, and in the acute setting of STEMI, it is not yet investigated. The COMPARE-ACUTE trial aims to investigate FFR-guided complete revascularization in comparison to a culprit lesion treatment–only strategy in STEMI patients with multivessel disease presenting for primary percutaneous coronary intervention.
