Communal Load Sharing of Miscarriage Experiences: Thematic Analysis of Social Media Community Support.

Background: Miscarriage is a common experience, affecting 15% of recognized pregnancies, but societal ignorance and taboos often downplay the mental distress and personal impact following a miscarriage. Emerging stories on social media in which women express their miscarriage grief are breaking such taboos. Research in the area of online health communities is increasingly focused on studying how people share their health experiences on social media.

Edoxaban Monotherapy and Incidence of Transcatheter Heart Valve Leaflet Thrombosis - The Rotterdam Edoxaban (REDOX) Study.

Background: Trials comparing non-vitamin K oral anticoagulant (NOAC) versus antiplatelet-based strategies have shown a reduction of subclinical leaflet thrombosis at the cost of increased mortality and major-bleedings. NOACs were often combined with antiplatelet therapy.

Aims: The Rotterdam Edoxaban (REDOX) study aimed to evaluate the impact of edoxaban monotherapy on the incidence of hypo-attenuated leaflet thickening (HALT) and reduced leaflet motion (RLM) and to evaluate safety in terms of mortality, thromboembolic events and major bleeding.

Conduction dynamics over time after transcatheter aortic valve replacement: An expert review.

New conduction disorders remain a frequent complication in current transcatheter aortic valve replacement (TAVR) era. Left bundle branch block (LBBB) occurs early in about 20-30 % of TAVR-patients, persists at 1 month in about 35-45 % of cases and will likely remain thereafter. Third-degree atrioventricular block (AV3B) affects approximately 15 % of patients.

Impact and limitations of 3D computational modelling in transcatheter mitral valve replacement-a two-centre Dutch experience.

Background: Transcatheter mitral valve replacement (TMVR) has emerged as a minimally invasive alternative to mitral valve surgery for patients at high or prohibitive operative risk. Prospective studies reported favourable outcomes in patients with annulus calcification (valve-in-mitral annulus calcification; ViMAC), failed annuloplasty ring (mitral valve-in-ring; MViR), and bioprosthetic mitral valve dysfunction (mitral valve-in-valve; MViV). Multi-slice computed tomography (MSCT)-derived 3D-modelling and simulations may provide complementary anatomical perspectives for TMVR planning.

Histamine H Receptor Isoforms: Insights from Alternative Splicing to Functional Complexity.

Alternative splicing significantly enhances the diversity of the G protein-coupled receptor (GPCR) family, including the histamine H receptor (HR). This post-transcriptional modification generates multiple HR isoforms with potentially distinct pharmacological and physiological profiles. HR is primarily involved in the presynaptic inhibition of neurotransmitter release in the central nervous system.

Changing haemodynamic status of patients referred for transcatheter aortic valve intervention during the COVID-19 pandemic.

Introduction: Delays in the diagnosis and referral of aortic stenosis (AS) during the coronavirus disease 2019 (COVID-19) pandemic may have affected the haemodynamic status of AS patients. We aimed to compare clinical and haemodynamic characteristics of severe AS patients referred for transcatheter aortic valve implantation (TAVI) or balloon aortic valvuloplasty (BAV) before the pandemic versus two subsequent periods.

Methods: This study compared three 1‑year historical cohorts: a pre-COVID-19 group (PCOV), a 1st-year COVID-19 group (COV-Y1) and a 2nd-year COVID-19 group (COV-Y2).

2-year outcomes of MitraClip as a bridge to heart transplantation: The international MitraBridge registry.

Background: In the first report from the MitraBridge registry, MitraClip as a bridge to heart transplantation (HTx) proved to be at 1-year an effective treatment strategy for 119 patients with advanced heart failure (HF) who were potential candidates for HTx. We aimed to determine if benefits of MitraClip procedure as a bridge-to-transplant persist up to 2-years.

Methods: By the end of the enrollment period, a total of 153 advanced HF patients (median age 59 years, left ventricular ejection fraction 26.

Acute Reduction in Left Ventricular Function Following Transcatheter Mitral Edge-to-Edge Repair.

Background Little is known about the impact of transcatheter mitral valve edge-to-edge repair on changes in left ventricular ejection fraction (LVEF) and the effect of an acute reduction in LVEF on prognosis. We aimed to assess changes in LVEF after transcatheter mitral valve edge-to-edge repair for both primary and secondary mitral regurgitation (PMR and SMR, respectively), identify rates and predictors of LVEF reduction, and estimate its impact on prognosis. Methods and Results In this international multicenter registry, patients with both PMR and SMR undergoing transcatheter mitral valve edge-to-edge repair were included.

Validation of a Three-Dimensional Computed Tomography Reconstruction Tool for Aortic Valve Calcium Quantification.

Background: Aortic valve calcification correlates with the severity of aortic valve stenosis and a high calcium score is associated with conduction disturbances and paravalvular leakage after transcatheter aortic valve replacement. The 3mensio Structural Heart is a semiautomated software package to facilitate aortic root analysis by multislice computed tomography.The aim of the contemporary study is to validate a semiautomated calcium quantification scoring tool with a conventional manual calcium quantification tool.

Transcatheter Aortic Valve Replacement in Patients With Reduced Ejection Fraction and Nonsevere Aortic Stenosis.

Background: The potential benefit of transcatheter aortic valve replacement (TAVR) in patients with nonsevere aortic stenosis (AS) and heart failure is controversial. This study aimed to assess outcomes of patients with nonsevere low-gradient AS (LGAS) and reduced left ventricular ejection fraction undergoing TAVR or medical management.

Methods: Patients undergoing TAVR for LGAS and reduced left ventricular ejection fraction (<50%) were included in a multinational registry.

Sex-Specific Differences in Aortic Valve Calcification Between Bicuspid and Tricuspid Severe Aortic Stenosis.

Sex-specific thresholds of aortic valve calcification (AVC) correlate with aortic stenosis (AS) and may complement echocardiography to determine AS severity. Importantly, current guideline-recommended thresholds of AVC scores derived by multislice computed tomography do not distinguish between bicuspid and tricuspid aortic valves. The objective of this study was to evaluate the sex-specific differences in the amount of AVC in patients with severe AS and tricuspid (TAV) versus bicuspid (BAV) aortic valve morphologies, retrospectively evaluated by 2 tertiary care institutions.

Sex-specific aortic valve calcifications in patients undergoing transcatheter aortic valve implantation.

Aims: To study sex-specific differences in the amount and distribution of aortic valve calcification (AVC) and to correlate the AVC load with paravalvular leakage (PVL) post-transcatheter aortic valve intervention (TAVI).

Methods And Results: This registry included 1801 patients undergoing TAVI with a Sapien3 or Evolut valve in two tertiary care institutions. Exclusion criteria encompassed prior aortic valve replacement, suboptimal multidetector computed tomography (MDCT) quality, and suboptimal transthoracic echocardiography images.

Assessing Adolescent Vaping Norms and Perceptions in a Statewide Multi-Community Project.

: Adolescent e-cigarette use has increased dramatically in recent years and is quickly becoming a serious public health issue. While studies have identified the influence of social norms on the use of traditional cigarettes, few have examined these factors in the context of e-cigarettes and other vaping devices. : The goal of this study was to examine social norms predictors of past 30-day e-cigarette use among high school students in 10 communities located in Minnesota.

Automated mitral valve assessment for transcatheter mitral valve replacement planning.

Transcatheter mitral valve replacement (TMVR) has emerged as a minimally invasive alternative for treating patients suffering from mitral valve disease. The number of TMVR procedures is expected to rise as devices currently in clinical trials obtain approval for commercialization. Automating the planning of such interventions becomes, therefore, more relevant in an attempt to decrease inter-subject discrepancies and time spent in patient assessment.

Impact of membranous septum length on pacemaker need with different transcatheter aortic valve replacement systems: The INTERSECT registry.

Background: New permanent pacemaker implantation (new-PPI) remains a compelling issue after Transcatheter Aortic Valve Replacement (TAVR). Previous studies reported the relationship between a short MS length and the new-PPI post-TAVR with a self-expanding THV. However, this relationship has not been investigated in different currently available THV.

Leaflet Thickening and Motion After Transcatheter Aortic Valve Replacement: Design and Rationale of the Rotterdam Edoxaban Trial.

Background: Multislice computed tomography (MSCT) may reveal hypo-attenuated leaflet thickening (HALT) and/or reduced leaflet motion (RELM) in approximately 15 % of patients after transcatheter aortic valve replacement (TAVR). These supposedly thrombogenic phenomena may be associated with neurological events and increased transprosthetic gradients. It is unclear whether oral anticoagulant therapy -specifically a factor Xa inhibitor- could affect the incidence of HALT/RELM.

Rationale and Design of the Project to Look for Early Discharge in Patients Undergoing TAVR With ACURATE (POLESTAR Trial).

Background: Transcatheter aortic valve replacement (TAVR) is now an established treatment strategy for elderly patients with symptomatic aortic stenosis (AS) across the entire operative risk spectrum. Streamlined TAVR protocols along with reduced procedure time and expedited ambulation promote early hospital discharge. Selection of patients suitable for safe early discharge after TAVR might improve healthcare efficiency.
