Background: The aim of this study was to perform a multicenter, prospective investigation regarding the epidemiology, the current effectiveness of therapeutic anticoagulation, and the risk of thromboembolism in patients with valvular atrial fibrillation (AF) based on the records of the Atrial Fibrillation in Turkey: Epidemiologic Registry (AFTER) study.
Methods: Patients were selected from a total of 2,242 consecutive admissions that presented with AF diagnosed via electrocardiogram. Those diagnosed with non-valvular AF were excluded from the AFTER study population, which left 497 patients with valvular AF for analysis.
Results: The etiology of valvular AF in patients was either attributed to rheumatic mitral valve stenosis (n = 217) or possessing a prosthetic heart valve (n = 280). Out of all the patients with valvular AF, 83.1% were taking warfarin for anticoagulation. Only 36.1% demonstrated a therapeutic international normalized ratio (INR), and among those patients it was found that 19.1% exhibited a labile INR. Multivariate analysis revealed that age was the only independent predictor of thromboembolic events in patients with valvular AF.
Conclusions: Many valvular AF patients are not maintained at therapeutic INR levels, which poses a threat to patient health as they age and are at greater risk for thromboembolism.

Background: Unlike non-rheumatic atrial fibrillation (AF), where left atrial thrombus (LAT) is predominantly confined to the left atrial appendage (LAA), a significant proportion of LAT in rheumatic AF occurs within the left atrial cavity (LAC). However, LAC thrombosis in rheumatic AF has not been extensively studied. This study aimed to evaluate the prevalence of LAT and its subtypes and identify potential predictors of LAT.

Aortic regurgitation (AR) is more prevalent in male, although cellular and molecular mechanisms underlying the sex differences in prevalence and pathophysiology are unknown. This study evaluates the impact of sex on aortic valve (AV) inflammation and remodeling as well as the cellular differences in valvular interstitial cells (VICs) and valvular endothelial cells (VECs) in patients with AR. A total of 144 patients (27.

Heyde's syndrome is a clinical entity that combines aortic stenosis, gastrointestinal angiodysplasia, and an acquired von Willebrand factor disorder. This syndrome is characterized by the association between aortic stenosis and recurrent gastrointestinal bleeding episodes, typically linked to angiodysplasias. Effective treatment requires addressing the underlying condition, specifically aortic stenosis, which leads to the structural destruction of coagulation proteins, resulting in the acquired von Willebrand factor disorder and perpetuating the bleeding.

Objectives: To examine HDP risk and impact on delivery timing in patients with CVD.
Methods: This retrospective cohort study included patients >18 years old who delivered between 10/1/2015 and 12/31/2020 using the Premier Healthcare Database.

Disorders of the pulmonic valve (PV) receive considerably less attention than other forms of valvular heart disease. Due to the dramatically improved survival of children with congenital heart disease over the last 5 decades, there has been a steady increase in the prevalence of adults with congenital heart disease, which necessitates that clinicians become familiar with the anatomy and the evaluation of right ventricular outflow tract and PV anomalies. A multimodality imaging approach using echocardiography, cardiac computed tomography, and magnetic resonance imaging is essential for a comprehensive evaluation of the anatomy and function of the right ventricular outflow tract, PV, and supravalvular region.
