Quality of Life After Mitral Transcatheter Edge-to-Edge Repair According to Baseline Tricuspid Regurgitation.

Background: There is a high prevalence of significant tricuspid regurgitation (TR) in patients undergoing mitral transcatheter edge-to-edge repair (M-TEER). Significant TR is associated with poor prognosis and affects decision-making between M-TEER and concomitant mitral and tricuspid valve surgery. Improved quality of life (QoL) is an important metric for patients.

Redefining respiratory sinus arrhythmia as respiratory heart rate variability: an international Expert Recommendation for terminological clarity.

The variation of heart rate in phase with breathing, known as 'respiratory sinus arrhythmia' (RSA), is a physiological phenomenon present in all air-breathing vertebrates. RSA arises from the interaction of several physiological mechanisms but is primarily mediated by rhythmic changes in cardiac parasympathetic (vagal) activity, increasing heart rate during inspiration and decreasing heart rate during expiration. RSA amplitude is an indicator of autonomic and cardiac health; RSA is diminished or absent in common pathological conditions such as chronic heart failure and hypertension.

Differential Immunological Responses of Adult Domestic and Bighorn Sheep to Inoculation with Type Strain Y98.

Bighorn sheep (BHS) populations have been reported to experience high levels of morbidity and mortality following infection with . This contrasts with the subclinical presentation in domestic sheep (DS). Understanding this difference requires baseline knowledge of pre- and post-infection immune responses of both species.

Upper respiratory tract detection of Mycoplasma ovipneumoniae employing nasopharyngeal swabs.

Background: Flock-level prevalence and characterization of Mycoplasma ovipneumoniae is determined almost exclusively using nasal swabbing followed by molecular detection with either quantitative PCR or multi-locus sequence typing. However, the diagnostic performance and efficiency of swabbing the nasal passage compared to other anatomical locations has not been determined within sheep populations. The goal of this research was to assess the diagnostic capability of nasopharyngeal swabs in comparison to nasal swabs for the detection of Mycoplasma ovipneumoniae.

Institutional Variation in Patient Radiation Doses During Transcatheter Valve Interventions: A Statewide Experience.

Background: Little is known about institutional radiation doses during transcatheter valve interventions.

Objectives: The authors sought to evaluate institutional variability in radiation doses during transcatheter valve interventions.

Methods: Using a large statewide registry, transcatheter edge-to-edge mitral valve repair, transcatheter mitral valve replacement, and transcatheter aortic valve replacement procedures between January 1, 2020, and December 31, 2022, with an air kerma (AK) recorded were analyzed.
