Elevated myocardial extracellular volume fraction is associated with the development of conduction pathway defects following transcatheter aortic valve replacement.

Background: Transcatheter aortic valve replacement (TAVR) has become an established method of aortic stenosis treatment but suffers from the risk of heart block and pacemaker requirement. Risk stratification for patients who may develop heart block remains imperfect. Simultaneously, myocardial fibrosis as measured by cardiac magnetic resonance imaging (CMR) has been demonstrated as a prognostic indicator of ventricular recovery and mortality following TAVR.

The Clinical Applications of Left Atrial Strain: A Comprehensive Review.

Left atrial (LA) strain imaging, which measures the deformation of the LA using speckle-tracing echocardiography (STE), has emerged recently as an exciting tool to help provide diagnostic and prognostic information for patients with a broad range of cardiovascular (CV) pathologies. Perhaps due to the LA's relatively thin-walled architecture compared with the more muscular structure of the left ventricle (LV), functional changes in the left atrium often precede changes in the LV, making LA strain (LAS) an earlier marker for underlying pathology than many conventional echocardiographic parameters. LAS imaging is typically divided into three phases according to the stage of the cardiac cycle: reservoir strain, which is characterized by LA filling during systole; conduit strain, which describes LA deformation during passive LV filling; and booster strain, which provides information on the LA atrium during LA systole in late ventricular diastole.

Percutaneous left atrial appendage occlusion in mitral valve disease: A Nationwide Readmission Database analysis.

Background: Percutaneous left atrial appendage occlusion (LAAO) has emerged as a non-pharmacologic alternative to oral anticoagulation in reducing stroke risk in AF patients. However, patients with mitral valve disease (MVD), who are expected to have a significantly greater risk of left atrium (LA) thrombus formation and embolic stroke were excluded from randomized trials examining percutaneous LAAO. To address this gap, we present a national registry analysis of the use of LAAO among patients with MVD.

Body Fat Distribution, Diabetes Mellitus, and Cardiovascular Disease: an Update.

Purpose Of Review: Specific measures of body fat distribution may have particular value in the development and treatment of cardiometabolic conditions, such as cardiovascular disease (CVD) and diabetes mellitus (DM). Here, we review the pathophysiology, epidemiology, and recent advances in the identification and management of body fat distribution as it relates to DM and CVD risk.

Recent Findings: Accumulation of visceral and ectopic fat is a major contributor to CVD and DM risk above and beyond the body mass index (BMI), yet implementation of fat distribution assessment into clinical practice remains a challenge.

Antineutrophil Cytoplasmic Autoantibody (ANCA)-Associated Vasculitis With Mucosal Involvement Following COVID-19 Pneumonia.

Antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitides (AAV) are a group of inflammatory disorders in which autoantibodies damage small arteries throughout the body, including in the upper and lower respiratory system, kidneys, as well as the skin. AAV may be precipitated by a variety of causes, including infections. In this report, we examine the case of a patient who developed AAV that was suspected primarily based on mucocutaneous hemorrhagic bullae, elevated ANCA levels, and subsequently confirmed by kidney biopsy, while recovering from coronavirus disease 2019 (COVID-19) infection.

"Robotic fatigue?" - The impact of case order on positive surgical margins in robotic-assisted laparoscopic prostatectomy.

Purpose: Multiple robotic-assisted surgeries are often performed within a single operating day; however, the impact of this practice on patient outcomes has not been examined. We aim to determine whether outcomes for robotic-assisted laparoscopic prostatectomy (RALP) differed when performed sequentially.

Materials And Methods: A multi-institutional, retrospective cohort study was conducted involving a total of 8 academic centers between years 2015 and 2018.

Do radiation oncologists and urologists endorse decision aids for active surveillance of low-risk prostate cancer: Results from a national survey.

Objective: The degree decision aids (DAs) can promote active surveillance (AS) for prostate cancer (PCa) remains poorly understood. Herein, we surveyed radiation oncologists (RO) and urologists (URO) about their attitudes towards DAs in counselling patients about AS for low-risk PCa.

Methods: We conducted a national survey of RO (n = 915) and URO (n = 940) to assess their attitudes about DAs for AS for patients with low-risk PCa.
