Characteristics, Trends, and Outcomes of Intravascular Lithotripsy-Assisted Transfemoral Transcatheter Aortic Valve Replacement in United States.

Background: Transfemoral (TF) access is the preferred approach for transcatheter aortic valve replacement (TAVR). Limited data exist regarding the outcomes of intravascular lithotripsy (IVL)-assisted TF TAVR in patients with peripheral artery disease.

Objectives: This study sought to examine contemporary characteristics, trends, and outcomes of IVL TAVR in the United States.

Determining Clinicopathologic Factors That Influence Treatment in Advanced Breast Cancer in Argentina After CDK4/6 Inhibitors.

Purpose: The optimal treatment sequence for hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC) after progression on first-line cyclin-dependent kinase 4/6 inhibitor (CDKi) and endocrine therapy is unclear. Clinical and biological factors influencing treatment choices and outcomes in the second-line setting need to be elucidated.

Materials And Methods: This is a retrospective analysis of a real-world cohort including patients with HR+/HER2- ABC who received CDKi and endocrine therapy in the first-line setting and progressed, requiring second-line treatment.

Radiomic study of antenatal prediction of severe placenta accreta spectrum from MRI.

Objectives: We previously demonstrated the potential of radiomics for the prediction of severe histological placenta accreta spectrum (PAS) subtypes using T2-weighted MRI. We aim to validate our model using an additional dataset. Secondly, we explore whether the performance is improved using a new approach to develop a new multivariate radiomics model.
