Heyde described aortic stenosis and gastrointestinal bleeding in the 1950s. Since then, a link with intestinal angiodysplasia and abnormalities of von Willebrand factor (VWF) has been noted. Loss of the highest-molecular-weight multimers of VWF and bleeding also have been described in subaortic stenosis in hypertrophic cardiomyopathy, in isolated mitral and aortic insufficiency, in endocarditis, in patients with prosthetic valve stenosis or regurgitation, and in patients with left ventricular assist devices (LVADs). Bleeding tends to recur with local treatment of angiodysplasias, whereas cardiac repair or removal of LVAD eliminates VWF dysfunction is curative of bleeding in the majority.

Purpose: To compare the overall survival and the risk of all-cause and heart failure-specific hospitalization in nonagenarian patients hospitalized for symptomatic severe aortic stenosis (AS) who underwent transcatheter aortic valve implantation (TAVI) or conservative treatment.
Methods: Population-based retrospective cohort study based on healthcare utilization databases of the Italian region of Lombardy. The cohort included all nonagenarians hospitalized for AS between 2017 and 2021, who underwent TAVI within 90 days from first diagnosis or conservative treatment.

Introduction And Importance: Severe aortic stenosis (AS) and chronic obstructive pulmonary disease (COPD) significantly increase perioperative morbidity and mortality. This case report discusses the challenges of managing a 75-year-old male patient with severe AS and advanced COPD undergoing elective abdominal aortic aneurysm (AAA) repair.
Case Presentation: The patient presented with a 6.

Background: Sengers syndrome is an autosomal recessive mitochondrial DNA depletion syndrome characterized by hypertrophic cardiomyopathy, congenital cataracts, skeletal myopathy, exercise intolerance, and lactic acidosis. Dysfunction of acylglycerol kinase (AGK) is responsible for the disease, and several AGK gene variants have been reported.
Methods: We employed a comprehensive genomic analysis approach, including whole-genome sequencing and RNA sequencing, combined with various bioinformatics tools.

Background: The coexistence of transthyretin cardiac amyloidosis (ATTR-CA) and aortic stenosis (AS) is increasingly recognized, but the clinical consequences are unclear. We aimed to characterize clinical outcomes in AS plus ATTR-CA compared with only AS or ATTR-CA.
Methods And Results: In a retrospective cohort study, patients with AS only, ATTR-CA only, or AS plus ATTR-CA were identified using all-payer claims data (2015-2021).
