Interobserver and intraobserver variability among different vendors for mitral valve assessment: implications for transcatheter mitral valve repair.
Radiol Med
January 2025
Department of Radiology, Mayo Clinic, 200 First Street SW, Rochester, MN, 55905, USA.
Purpose: Pre-procedural imaging is critical for transcatheter mitral valve repair planning in patients with mitral valve disease. As differences among various measurement techniques for valve evaluation are still poorly understood, we sought to assess the intra- and interobserver agreement of complex measurements derived from a prototype mitral evaluation tool (Siemens) and a commercially available tool (CVI42) using both saddle- and D-shaped mitral annulus techniques.
Materials And Methods: Multiphasic cardiac computed tomography angiography data were loaded into each software.
Resting beat-to-beat blood pressure variability in humans: role of alpha-1 adrenergic receptors.
Clin Auton Res
January 2025
Department of Health and Kinesiology, Purdue University, West Lafayette, Indiana, USA.
Purpose: Resting beat-to-beat blood pressure variability is a strong predictor of cardiovascular events and mortality. However, its underlying mechanisms remain incompletely understood. Given that the sympathetic nervous system plays a pivotal role in cardiovascular regulation, we hypothesized that alpha-1 adrenergic receptors (the main sympathetic receptor controlling peripheral vasoconstriction) may contribute to resting beat-to-beat blood pressure variability.

Hypertens Res

Department of Cardiology, Kurume University Medical Center, 155-1 Kokubu-machi, Kurume, Fukuoka, 839-0863, Japan.
The ratio of serum acylcarnitines to free carnitines (AC/FC) reflects impaired cardiomyocyte β-oxidization. The effect of heart failure (HF) treatment on AC/FC remained unclear. This pilot study retrospectively examined treatment-induced AC/FC changes in patients with HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF) in 148 consecutive inpatients undergoing echocardiography and carnitine measurement at admission and discharge.

Department of Cardiothoracic Surgery, Vanderbilt University Medical Center, Nashville, Tennessee.
Background: Ex-vivo lung perfusion (EVLP) has potential to expand donor lung utilization, evaluate allograft viability, and mitigate ischemia-reperfusion injury. However, trends in EVLP use and recipient outcomes are unknown on a national scale. We examined trends in EVLP use and recipient outcomes in the United States.

January 2025
J. L. Andréu Sánchez, PhD, Rheumatology department, Puerta de Hierro Majadahonda University Hospital, Autonoma University, Madrid, Spain.
Objective: To quantify the mortality risk in a large, well-characterized cohort of Sjögren's disease (SjD) patients and to identify independent predictors of mortality in this population.
Methods: We included 314 patients diagnosed with SjD according to the 2002 American-European Consensus Group criteria from a prospective, multicenter SjögrenSER-PROS cohort. Detailed data on systemic manifestations, serological markers, disease activity, and mortality was collected after 9 years of follow up.
