Prognostic Value of Advanced Echocardiographic Analysis for Transcatheter Aortic Valve Replacement: A Systematic Review.

Transcatheter aortic valve implantation (TAVI) is the main treatment option for patients with severe aortic stenosis (AS) and older age. Improved imaging techniques have enabled better patient selection, and the main role is played by echocardiography. Methods more sensitive than LVEF in assessing cardiac function, such as global longitudinal strain (GLS) and myocardial work (MW), have become widespread, and other methods, like hemodynamic forces (HDFs), might be promising.

Rivaroxaban for Patients with Intermittent Claudication.

Background: The combination of rivaroxaban plus aspirin compared with aspirin alone reduces the risk of major adverse cardiovascular and limb events for high-risk patients with peripheral artery disease. It is unknown whether rivaroxaban plus aspirin improves intermittent claudication for adults with lower-risk peripheral arterial disease.

Methods: In this randomized, open-label, multicenter, 24-week clinical trial, we randomly assigned patients with peripheral artery disease and intermittent claudication to receive either 2.

Arrhythmic Mitral Valve Prolapse Phenotype: An Unsupervised Machine Learning Analysis Using a Multicenter Cardiac MRI Registry.

Purpose To use unsupervised machine learning to identify phenotypic clusters with increased risk of arrhythmic mitral valve prolapse (MVP). Materials and Methods This retrospective study included patients with MVP without hemodynamically significant mitral regurgitation or left ventricular (LV) dysfunction undergoing late gadolinium enhancement (LGE) cardiac MRI between October 2007 and June 2020 in 15 European tertiary centers. The study end point was a composite of sustained ventricular tachycardia, (aborted) sudden cardiac death, or unexplained syncope.
