Elevated left atrial pressure during exercise is a hallmark of heart failure (HF) and is associated with adverse left atrial remodeling and poor outcomes. To decompress the pressure-overloaded left atrium in patients with HF, several device-based approaches have been developed to create a permanent, pressure-dependent, left-to-right interatrial shunt. Such approaches are currently in various stages of investigations in both HF with reduced ejection fraction (EF) and HF with preserved EF. This review discusses the evolution of the concept of left atrial decompression and summarizes the current landscape of device-based approaches used for left atrial decompression.

An atrial septal defect (ASD) is a common congenital heart anomaly that results in irregular blood flow between the systemic and pulmonary circulations due to an opening in the atrial septum. Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.

Nondilated left ventricular cardiomyopathy (NDLVC) is a newly defined category of cardiomyopathy. We sought to evaluate and compare the phenotype of NDLVC with DCM using cardiac magnetic resonance (CMR) imaging and to investigate the prognostic significance of these conditions. One hundred and fifty patients suspected of having cardiomyopathy referred for CMR were recruited.

December 2024
Department of Cardiovascular Surgery, Mayo Clinic Rochester, Rochester, Minnesota, USA.
Background: Population-based analyses may reduce uncertainty related to referral bias and/or incomplete follow-up.
Objectives: This study analyzed long-term mortality and durability of mitral valve repair in a geographically defined population with clinical and echocardiographic follow-up.
Methods: We used the Rochester Epidemiology Project to identify 153 Olmsted County patients who underwent mitral valve repair for degenerative regurgitation from 1993 to 2018.
Left Atrial Dimension and CHADS-VASc Score in Predicting Stroke in Patients with Rheumatic Atrial Fibrillation.
JACC Adv
December 2024
Division of Cardiology, Department of Internal Medicine, National Taiwan University Hospital, Taipei, Taiwan.
Background: Rheumatic atrial fibrillation (AF) patients are at an elevated risk of stroke events, yet the associated risk factors remain unclear.
Objectives: This study aimed to evaluate the effectiveness of the CHADS-VASc score in predicting stroke events in rheumatic AF patients and explore potential enhancements for increased predicting accuracy in the Asian population, comparing it to nonvalvular AF.
Methods: A retrospective cohort study spanning March 2010 to December 2020 included 29,341 AF patients followed up for up to 10 years, with 1,942 identified as having rheumatic AF.
Feasibility and efficacy of 50 W ablation with the TactiFlex catheter for the initial pulmonary vein isolation of atrial fibrillation.

Department of Cardiology Saitama Medical University, International Medical Center Hidaka Japan.
Background: A novel contact force (CF) sensing catheter with a mesh-shaped irrigation tip (TactiFlexTM SE, Abbott), is expected to provide safe and effective radiofrequency ablation. Our previous study revealed that the TactiFlex catheter needs a higher power for pulmonary vein isolation (PVI) due to the long tip length. This study aimed to examine the feasibility and safety of a 50 W ablation with the TactiFlex for PVI of atrial fibrillation (AF).
