Hot topics in interventional cardiology: Proceedings from the society for cardiovascular angiography and interventions 2020 think tank.

The society for cardiovascular angiography and interventions (SCAI) think tank is a collaborative venture that brings together interventional cardiologists, administrative partners, and select members of the cardiovascular industry community for high-level field-wide discussions. The 2020 think tank was organized into four parallel sessions reflective of the field of interventional cardiology: (a) coronary intervention, (b) endovascular medicine, (c) structural heart disease, and (d) congenital heart disease (CHD). Each session was moderated by a senior content expert and co-moderated by a member of SCAI's emerging leader mentorship program.

Determining the Suitability of Registries for Embedding Clinical Trials in the United States: A Project of the Clinical Trials Transformation Initiative.

Background: Patient registries are organized systems that use observational methods to collect uniform data on specified outcomes in a population defined by a particular disease, condition, or exposure. Data collected in registries often coincide with data that could support clinical trials. Integrating clinical trials within registries to create registry-embedded clinical trials offers opportunities to reduce duplicative data collection, identify and recruit patients more efficiently, decrease time to database lock, accelerate time to regulatory decision-making, and reduce clinical trial costs.

Defining high bleeding risk in patients undergoing percutaneous coronary intervention: a consensus document from the Academic Research Consortium for High Bleeding Risk.

Identification and management of patients at high bleeding risk undergoing percutaneous coronary intervention are of major importance, but a lack of standardization in defining this population limits trial design, data interpretation, and clinical decision-making. The Academic Research Consortium for High Bleeding Risk (ARC-HBR) is a collaboration among leading research organizations, regulatory authorities, and physician-scientists from the United States, Asia, and Europe focusing on percutaneous coronary intervention-related bleeding. Two meetings of the 31-member consortium were held in Washington, DC, in April 2018 and in Paris, France, in October 2018.

Defining High Bleeding Risk in Patients Undergoing Percutaneous Coronary Intervention.

Identification and management of patients at high bleeding risk undergoing percutaneous coronary intervention are of major importance, but a lack of standardization in defining this population limits trial design, data interpretation, and clinical decision-making.

Selection of prosthetic aortic valves in the United States among elderly Medicare patients from 2006 to 2015.

Background: Both biological and mechanical prosthetic valves are treatment choices for aortic valve replacement. We aimed to characterize the selection of prosthetic aortic valves among elderly Medicare patients.

Methods: This was a retrospective analysis of patients aged 65 years or older who underwent aortic valve replacement alone or in combination with other procedures in the 2006-2015 Medicare databases.

Association Between Hospital Surgical Aortic Valve Replacement Volume and Transcatheter Aortic Valve Replacement Outcomes.

Importance: The Centers for Medicare & Medicaid Services national coverage determination for transcatheter aortic valve replacement (TAVR) includes volume requirements for surgical aortic valve replacement (SAVR) for hospitals seeking to initiate or continue TAVR programs. Evidence regarding the association between SAVR volume and TAVR outcomes is limited.

Objective: To examine the association of hospital SAVR and combined SAVR and TAVR volumes with patient outcomes of TAVR procedures performed within 1 year, 2 years, and for the entire period after initiation of TAVR programs.

Sex-Specific Outcomes After Transcatheter Aortic Valve Replacement: FDA Patient-Level Meta-Analysis of Premarket Clinical Trials.

Background: Transcatheter aortic valve replacement (TAVR) is a less invasive alternative approach to surgery. Individual randomized clinical trials evaluating the safety and efficacy of TAVR were mostly underpowered for conducting separate analyses for women and men. We pooled data from premarket TAVR clinical trials comparing short (30 days)- and long-term (∼2 years) outcomes by sex.

Sex-Specific Outcomes After Transcatheter Aortic Valve Replacement: A Review of the Literature.

Transcatheter aortic valve replacement (TAVR) is a safe and effective therapy for aortic valve replacement in patients ineligible for or at high risk for surgery. However, outcomes after TAVR based on an individual's sex remain to be fully elucidated. We searched PUBMED and EMBASE using the keywords: "transcatheter aortic valve replacement," "transcatheter aortic valve implantation," "sex differences," "gender," "sex characteristics" and collected information on baseline features, procedural characteristics, and postprocedural outcomes in women.

Predictable and SuStainable Implementation of National Cardiovascular Registries (PASSION) infrastructure: A think tank report from Medical Device Epidemiological Network Initiative (MDEpiNet).

The MDEpiNet is a public-private partnership between the US Food and Drug Administration's Center for Devices and Radiological Health and participating partners. The PASSION program is an MDEpiNet-sponsored program that aims to demonstrate the goals of MDEpiNet by using cardiovascular medical device registries to bridge evidence gaps across the medical device total product life cycle. To this end, a PASSION Think Tank meeting took place in October 2014 in Silver Spring, MD, to facilitate discussion between stakeholders about the successes, challenges, and future novel applications of medical device registries, with particular emphasis on identifying pilot projects.

Early mortality after aortic valve replacement with mechanical prosthetic vs bioprosthetic valves among Medicare beneficiaries: a population-based cohort study.

Importance: Early mortality for patients who undergo aortic valve replacement (AVR) may differ between mechanical and biological prosthetic (hereinafter referred to as bioprosthetic) valves. Clinical trials may have difficulty addressing this issue owing to limited sample sizes and low mortality rates.

Objective: To compare early mortality after AVR between the recipients of mechanical and bioprosthetic aortic valves.

Patterns of anticoagulation following bioprosthetic valve implantation: observations from ANSWER.

Background And Aim Of The Study: The American College of Cardiology/American Heart Association (ACC/AHA) guidelines recommend a three-month administration of warfarin following bioprosthetic valve replacement (BVR). However, strong evidence supporting this recommendation is lacking, making process variation likely.

Methods: In the ANSWER Registry, a total of 386 patients who had received either Epic or Biocor BVRs between May 2007 and August 2008 at 40 centers was enrolled.

Intraoperative effects of the coapsys annuloplasty system in a randomized evaluation (RESTOR-MV) of functional ischemic mitral regurgitation.

Background: Functional ischemic mitral regurgitation (MR) frequently arises after myocardial infarction; it is characterized by annular enlargement or lateral displacement of the subvalvular apparatus. Coapsys is a ventricular-annular remodeling device designed to treat functional ischemic MR; it does not require cardiopulmonary bypass. Initial intraoperative results of the RESTOR-MV randomized clinical trial are presented.

A multi-institutional experience with the CryoMaze procedure.

Background: The Cox Maze III operation remains the gold standard for the surgical treatment of atrial fibrillation (AF). We report our experience using a flexible argon-powered metal cryoprobe for creation of the complete Cox-Maze III lesion set in patients with AF (the CryoMaze operation).

Methods: Beginning July 2002, 38 patients underwent the CryoMaze operation.
