Aim To compare the long-term effectiveness of cryoballoon ablation (CBA) and radiofrequency ablation (RFA) in patients with atrial fibrillation (AF).Material and methods This retrospective single-site study included 597 patients with AF who had undergone CBA (n=241) or RFA (n=356) between 2016 and 2024. The study participants included 355 men (59.

Background: Acute myocardial infarction (AMI) patients with prior malignancy have been largely understudied, despite potentially facing higher risks of adverse outcomes. This case-control study aimed to identify independent risk factors for in-hospital mechanical complications among AMI patients with prior malignancies.
Methods: This study enrolled AMI patients with prior malignancy who were hospitalized for treatment.

Introduction: Mitral annular disjunction (MAD) is a pathologic fibrous separation of the mitral valve hinge point from the ventricular myocardium. The aims of this study were to describe the range of MAD distance by cardiac magnetic resonance (CMR) in children and young adults with connective tissue disorders (CTDs) versus a healthy control sample, and to assess the MAD distance as a predictor of adverse cardiovascular outcomes.
Methods: This was a retrospective, single-center study of healthy subjects and patients with Marfan syndrome, Loeys-Dietz syndrome, Ehlers-Danlos syndrome, or nonspecific CTD who underwent CMR between 01/01/2000 and 01/01/2020.

Objective: This study sought to identify key prognostic factors in patients with hypertrophic cardiomyopathy (HCM) and heart failure with preserved ejection fraction (HFpEF), emphasizing the prognostic role of free triiodothyronine (FT3) levels.
Research Design And Methods: This retrospective cohort study enrolled 992 HCM-HFpEF patients from two Chinese medical centers between 2009 and 2019, excluding those with thyroid-affecting medications or disorders. Data on demographic and clinical variables, including FT3, were analyzed using univariate and multivariate Cox regression, Kaplan-Meier (KM) survival analysis, and restricted cubic spline (RCS) analysis to explore prognostic factors and FT3's nonlinear predictive value.

Background: The recurrence of arrhythmia following catheter ablation of macro-reentrant atrial tachycardia (MRAT) in repaired tetralogy of Fallot (rTOF) is poorly understood.
Objective: To better describe the incidence, mechanisms, and predictors of recurrent atrial arrhythmia following MRAT ablation in rTOF.
Methods: Patients with rTOF ≥18 years of age who underwent radiofrequency ablation for MRAT (typical/cavotricuspid isthmus-dependent atrial flutter, incisional/scar-mediated MRAT, upper and lower-loop reentry, or left atrial MRAT) at Duke University Hospital from 1996 to 2023 were identified.
