Objectives The aim of this study was to investigate age-related outcomes of patients undergoing transcatheter aortic valve replacement (TAVR) as assessed in a nationwide, prospective, multicenter cohort study.
Objectives The aim of this study was to assess the outcomes of severe prosthesis-patient mismatch (PPM) in the TVT (Transcatheter Valve Therapy) Registry in patients undergoing supra-annular transcatheter aortic valve replacement (TAVR) for de novo stenosis or failed surgical bioprostheses (transcatheter aortic valve [TAV]–in–surgical aortic valve [SAV]).
Objectives The aim of this study was to validate the 2019 consensus algorithm in a large cohort of contemporary transcatheter aortic valve replacement (TAVR) patients.
Although congenital coronary artery anomalies are relatively rare, they are the second most common cause of sudden cardiac death among young athletes. When encountered in the cardiac catherization laboratory, they are often challenging to selectively engage, requiring multiple catheters, plus increased contrast volume and radiation exposure. In the setting of acute coronary syndromes, it is not infrequent that percutaneous intervention is delayed because of the inability to engage an anomalous coronary artery. The aim of this review is to provide a comprehensive and concise overview of coronary artery anomalies, with particular attention to diagnostic and guide catheter selection for each type of anomaly and recommendations on how to recognize the vessel course angiographically.
Objectives The authors sought to determine whether coronary artery tortuosity negatively affects clinical outcomes after stent implantation.
Objectives The aim of this study was to develop pre-procedural intravascular ultrasound (IVUS)–based models for predicting the occurrence of stent underexpansion.
Objectives The authors sought to assess sex-based differences in characteristics and outcomes of patients undergoing transcatheter edge-to-edge mitral valve repair (TMVR) for secondary mitral regurgitation (SMR).
Objectives The authors report 1-year outcomes of high-risk patients with failed surgical annuloplasty rings undergoing transseptal mitral valve–in–ring (MViR) with the SAPIEN 3 aortic transcatheter heart valve (THV).
Objectives The aim of this study was to evaluate 1-year outcomes of valve–in–mitral annular calcification (ViMAC) in the MITRAL (Mitral Implantation of Transcatheter Valves) trial.
Objectives The aim of this study was to assess 1-year clinical outcomes among high-risk patients with failed surgical mitral bioprostheses who underwent transseptal mitral valve-in-valve (MViV) with the SAPIEN 3 aortic transcatheter heart valve (THV) in the MITRAL (Mitral Implantation of Transcatheter Valves) trial.
Objectives The authors sought to evaluate the association between mean mitral valve gradient (MVG) and clinical outcomes among patients who underwent MitraClip treatment for secondary mitral regurgitation (SMR) in the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial.
Among patients undergoing percutaneous coronary procedures, transradial access, compared with transfemoral access, is associated with a reduced risk for complications including mortality, especially in higher risk patients. However, transradial access is limited by radial artery occlusion (RAO) that despite being mostly asymptomatic because of the extensive anastomoses between the forearm arteries restricts future use of the same radial artery. Distal radial access (DRA) in the anatomic snuffbox or on the dorsum of the hand has recently gained global popularity as an alternative access route for vascular procedures. A strong anatomic and physiological rationale yields potential for significantly reduced risk for RAO and positive impact on procedural outcome for better patient care. Indeed, currently published studies buttress very low rates of RAO after DRA, hence supporting its development. The authors provide an analysis of the foundation of DRA, provide historical background, and offer a critical review of its current status and future directions. Also, given the limited evidence currently available to properly perform DRA in the real world, consensus opinion on what is considered optimal practice is also presented to supplement this document and enhance the implementation of DRA while minimizing its complications.
The aims of this study were to examine rates of radial artery access in post–coronary artery bypass grafting (CABG) patients undergoing diagnostic catherization and/or percutaneous coronary intervention (PCI), whether operators with higher procedural volumes and higher percentage radial use were more likely to perform diagnostic catherization and/or PCI via the radial approach in post-CABG patients, and clinical and procedural outcomes in post-CABG patients who undergo diagnostic catherization and/or PCI via the radial or femoral approach.
Antithrombotic therapy represents the mainstay of treatment in patients with coronary artery disease (CAD), including elderly patients who are at increased risk for ischemic recurrences. However, the elderly population is also more vulnerable to bleeding complications. Numerous mechanisms, including abnormalities in the vasculature, thrombogenicity, comorbidities, and altered drug response, contribute to both increased thrombotic and bleeding risk. Age-related organ changes and drug-drug interactions secondary to polypharmacy lead to distinct pharmacokinetic and pharmacodynamic profiles of antithrombotic drugs. Overall these factors contribute to the risk-benefit profiles of antithrombotic therapies in elderly subjects and underscore the need for treatment regimens that can reduce bleeding while preserving efficacy. Given that the prevalence of CAD, as well as concomitant diseases with thromboembolic potential, such as atrial fibrillation, increases with age and that the elderly population is in continuous growth, understanding the safety and efficacy of different antithrombotic regimens is pivotal for patient-centered care. In the present overview the authors appraise the available data on the use of antithrombotic therapy in older patients with CAD to assist with the management of this high-risk population and define knowledge gaps that can set the basis for future research.
Objectives The aim of this study was to examine the effect of CYP2C19 genotype on clinical outcomes in patients with coronary artery disease (CAD) who predominantly underwent percutaneous coronary intervention (PCI), comparing those treated with ticagrelor or prasugrel versus clopidogrel.
