Early safety after TAVR according to VARC-3 criteria: incidence, predictors, and clinical impact.

Introduction And Objectives: The Valve Academic Research Consortium (VARC)-3 definition of the early safety (ES) composite endpoint after transcatheter aortic valve replacement (TAVR) lacks clinical validation. The aim of this study was to determine the incidence, predictors, and clinical impact of ES after TAVR as defined by VARC-3 criteria.

Methods: We performed a multicenter study including 10 078 patients with severe aortic stenosis undergoing transarterial TAVR.

Transcatheter Aortic Valve Replacement in Aortic Stenosis Patients With New York Heart Association Functional Class III or IV.

Background: Patients with symptomatic aortic stenosis are a vulnerable population with associated cardiac damage and a significant comorbidity burden. In this study we aimed to determine the rate, factors associated with, and prognostic value of poor functional status (New York Heart Association [NYHA] class III-IV) in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR).

Methods: This multicenter study included 6363 transarterial TAVR patients, classified according to baseline functional status (NYHA class I or II vs III or IV).

Post-transplant relapse in pediatric acute lymphoblastic leukemia in the era of CAR-T cell therapy. A multicenter analysis of Grupo Español de Trasplante Hematopoyetico y Terapia Celular (GETH-TC) Pediatric Committee.

Background: The management of relapsed acute lymphoblastic leukemia (ALL) after hematopoietic stem cell transplantation (HSCT) has evolved significantly. Initially, treatment options were limited to palliative care, salvage chemotherapy, and second HSCT. Currently, the focus has shifted to innovative immunotherapies, particularly CAR T-cell therapy.

Novel cardiac CT method for identifying the atrioventricular conduction axis by anatomic landmarks.

Background: Understanding the conduction axis location aids in avoiding iatrogenic damage and guiding targeted heart rhythm therapy.

Objective: Cardiac structures visible with clinical imaging have been demonstrated to correlate with variability in the conduction system course. We aimed to standardize and assess the reproducibility of predicting the location of the atrioventricular conduction axis by cardiac computed tomography.

Prospective validation of a prespecified algorithm for the management of conduction disturbances after transcatheter aortic valve replacement: The PROMOTE study.

Background: There is a large variability in the management of conduction disturbances (CDs) after transcatheter aortic valve replacement (TAVR).

Objective: This study aimed to validate a prespecified algorithm for managing CDs in patients undergoing TAVR.

Methods: This was a prospective multicenter study including consecutive patients without prior pacemaker undergoing TAVR.
