Optimal ablation pattern on Intraprocedural echocardiography is associated with favorable clinical outcomes of alcohol septal ablation for hypertrophic obstructive cardiomyopathy.

Background: Alcohol septal ablation (ASA) is used to treat drug-refractory hypertrophic obstructive cardiomyopathy (HOCM). Intraprocedural echocardiography is essential for identifying the septal area perfused by each septal branch; however, its role in determining the procedural endpoint of ASA remains unclear. This retrospective study aimed to evaluate the impact of intraprocedural echocardiographic findings on clinical outcomes and left ventricular pressure gradient (LVPG) after ASA.

Machine learning models for dementia screening to classify brain amyloid positivity on positron emission tomography using blood markers and demographic characteristics: a retrospective observational study.

Background: Intracerebral amyloid β (Aβ) accumulation is considered the initial observable event in the pathological process of Alzheimer's disease (AD). Efficient screening for amyloid pathology is critical for identifying patients for early treatment. This study developed machine learning models to classify positron emission tomography (PET) Aβ-positivity in participants with preclinical and prodromal AD using data accessible to primary care physicians.

A Case of Eltrombopag-Induced Thrombotic Microangiopathy Initiating Hemodialysis.

Thrombopoietin receptor agonists are used in addition to steroids for idiopathic thrombocytopenic purpura. A 55-year-old male with idiopathic thrombocytopenic purpura, treated with eltrombopag, developed a rapid decline in renal function following the increase in eltrombopag dose. Renal biopsy showed glomerular endothelial disorder and platelet thrombus, which suggested eltrombopag-induced renal-limited thrombotic microangiopathy.

Clinically relevant haemolysis after transcatheter aortic valve implantation with new-generation balloon-expandable valve.

Background: Valve-related haemolysis is a known complication following prosthetic valve surgery. Haemolysis after transcatheter aortic valve implantation (TAVI) has been reported in some studies, all of which were non-critical. Data related to haemolysis associated with new-generation balloon-expandable valve (BEV) are scarce.
