Objectives: This study sought to evaluate the trends and outcomes of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) among patients with prior mediastinal radiation from a national database.

Background: There is a paucity of data about the temporal trends and outcomes of TAVR versus SAVR in patients with prior mediastinal radiation.

Methods: The National Inpatient Sample database years 2012 to 2017 was queried for hospitalizations of patients with prior mediastinal radiation who underwent isolated AVR.

Background: We sought to evaluate the nationwide trends in the characteristics and outcomes of for endovascular stroke therapy in contemporary practice.

Methods: We selected patients with acute ischemic stroke who underwent endovascular stroke therapy between 01 October 2015 and 30 September 2019 in a large academic consortium database. The end points of this study were (a) in-hospital mortality and functional outcomes and, (b) predictors of poor functional outcome, defined as death or discharge to hospice, or to a long-term nursing facility.

Objective: To evaluate the contemporary trends in outcomes and resource use associated with transcatheter aortic valve replacement (TAVR) in the United States.

Methods: We identified patients who underwent TAVR between January 1, 2012, and December 31, 2017, in the National Readmission Database. We assessed temporal trends in clinical outcomes, length-of-stay, non-home discharges, and cost of the index TAVR hospitalization.

Background Aortic stenosis-related mortality might vary across demographic subsets, regions, and states in the United States. Methods and Results We reviewed the death certificate data from the Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research database to examine aortic stenosis-related mortality trends from 2008 to 2018. Crude and age-adjusted mortality rates (AAMRs) per 100 000 people and annual percentage change with 95% CIs were calculated.

Objectives: The aim of this study was to evaluate the outcome of transcatheter mitral valve repair (TMVr) in patients with cardiogenic shock and significant mitral regurgitation (MR).

Background: Patients in cardiogenic shock with severe MR have a poor prognosis in the setting of conventional medical therapy. Because of its favorable safety profile, TMVr is being increasingly used as an acute therapy in this population, though its efficacy remains unknown.

Objectives And Background: There is insufficient current evidence about whether sex impacts outcomes of percutaneous left atrial appendage occlusion (LAAO). The aim of this study was to investigate the association between sex and short-term outcomes of LAAO.

Methods: Patients who were hospitalized and underwent LAAO from October 2015 to December 2017 in the National Readmission Database were queried.

Introduction: Catheter ablation has shown to reduce mortality in patient with atrial fibrillation (AF) and heart failure (HF) with reduced ejection fraction. Its effect on mortality in patients without HF has not been well elucidated.

Methods: Thirteen randomized controlled trials encompassing 3856 patients were selected using PubMed, Embase and the CENTRAL till April 2019.

Objectives: The aim of this study was to assess the 30 day incidence of paravalvular leak (PVL) and need for aortic valve reintervention of a fourth generation balloon expandable transcatheter valve with enhanced skirt (4G-BEV) (SAPIEN 3 Ultra) compared with a third generation balloon expandable transcatheter valve (3G-BEV) (SAPIEN 3).

Background: The incidence of PVL has steadily declined with iterative improvements in transcatheter aortic valve replacement (TAVR) technology and implantation strategies.

Methods: Patients who underwent TAVR at Mayo Clinic from 7/2018 to 7/2019 were included in a prospective institutional registry.

Left atrial appendage closure has emerged as a feasible stroke prevention strategy in selected patients with nonvalvular atrial fibrillation. Since its commercial approval in the United States in 2015, the use of percutaneous left atrial appendage closure has witnessed a substantial growth. However, certain issues remain unresolved with the technology.

Objectives: We aimed to investigate the invasive hemodynamic changes with transcatheter mitral valve replacement (TMVR) in patients with severe mitral stenosis due to severe mitral annular calcification.

Background: The hemodynamic response to TMVR in patients with mitral stenosis related to degenerative mitral annular calcification has not been fully elucidated.

Methods: We conducted retrospective review of patients who underwent successful transseptal TMVR with balloon-expandable valves for symptomatic severe mitral stenosis due to mitral annular calcification at our institution between January 2014 and February 2020.

Data on emergency coronary artery bypass surgery (CABG) are limited. We studied patients who underwent isolated CABG at Mayo Clinic between 1993 and 2019. Baseline characteristics and in-hospital outcomes of emergent CABG were described in consecutive eras (1993 to 2000, 2001 to 2010, and 2011 to 2019).

Aims: The Food and Drug Administration (FDA) approval of the Watchman device [percutaneous left atrial appendage occlusion (LAAO)] has resulted in the widespread use of this procedure in many centres across the USA. We sought to estimate the nationwide utilization and frequency of adverse outcomes associated with Watchman device implantation. The objective of this study was to evaluate the Watchman device implantation peri-procedural complications and comparison of the results with the previous studies.

Background: The management of patients with severe but asymptomatic aortic stenosis is challenging. Evidence on early aortic valve replacement (AVR) versus symptom-driven intervention in these patients is unknown.

Methods: Electronic databases were searched, articles comparing early-AVR with conservative management for severe aortic stenosis were identified.

Objectives: To assess the Usefulness of oral anticoagulation therapy (OAT) in patients with coronary artery aneurysm (CAA).

Background: Data on the most adequate antithrombotic CAA management is lacking.

Methods: Patients included in CAAR (Coronary Artery Aneurysm Registry, Clinical Trials.

Background Nationwide studies documenting temporal trends in permanent pacemaker implantation (PPMI) following transcatheter aortic valve replacement (TAVR) are limited. Methods and Results We selected patients who underwent TAVR between 2012 and 2017 in the National Readmission Database. The primary end point was the 6-year trend in post-TAVR PPMI at index hospitalization and at 30, 90, and 180 days after discharge.

Objectives: The aim of this study was to assess whether offering local endovascular stroke therapy (EST) rather than transferring patients off-site to receive EST would improve outcomes.

Background: There are limited data to determine whether offering EST on-site rather than transferring patients to receive EST off-site improves clinical outcomes.

Methods: A large academic consortium database was queried to identify patients with acute ischemic stroke who received EST between October 2015 and September 2019.

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia encountered in clinical practice. However, the outcomes associated with AF in hospitalized patients with liver cirrhosis are unknown.

Aim: To determine the outcomes of hospitalized patients with liver cirrhosis and AF.

Transcatheter mitral valve replacement (TMVR) with off-label use of aortic balloon-expandable transcatheter heart valves has emerged as a therapeutic option in high-surgical risk patients with severe mitral annular calcification. Left ventricular outflow tract (LVOT) obstruction post valve deployment is a major limitation. We describe a case of septal reduction therapy using radiofrequency ablation (RFA) when established methods of septal reduction were either ineffective or not feasible.
