Association between lipoprotein(a) and thromboembolism in patients with non-valvular atrial fibrillation: a cross-sectional study

Lipids in Health and Disease, 2022
Background Lipoprotein(a) [Lp(a)] is a recognized risk factor for ischemic stroke (IS); however, its role in thromboembolism in patients with non-valvular atrial fibrillation (NVAF) remains controversial.

Left Bundle Branch Pacing in Transthyretin Cardiac Amyloidosis and Alternating Bundle Branch Block

JACC: Case Reports, 2020
Progressive conduction system disease affects patients with transthyretin cardiac amyloidosis, often requiring permanent pacing as the His-Purkinje system is affected. We present a case of left bundle branch pacing in a patient with transthyretin cardiac

Postcardiac injury syndrome caused by radiofrequency catheter ablation of persistent atrial fibrillation: severe pulmonary arterial hypertension with severe tricuspid regurgitation: a rare case report and literature review

BMC Cardiovascular Disorders, 2023
Background Postcardiac injury syndrome (PCIS) is an easy-to-miss diagnosis, but it is not an uncommon complication. The phenomenon of echocardiography (ECHO) showing both severe pulmonary arterial hypertension (PAH) and severe tricuspid regurgitation (TR)

Hybrid Ablation of Atrial Fibrillation: A Contemporary Overview

Journal of Cardiovascular Development and Disease, 2022
Electrical isolation of pulmonary veins (PVI) is the cornerstone of invasive treatment of atrial fibrillation (AF). However, arrhythmia-free survival of a PVI only approach is suboptimal in patients with persistent and long-term persistent AF.

Experimentally-calibrated population of models predicts and explains inter-subject variability in cardiac cellular\ud electrophysiology [PDF]

, 2013
Cellular and ionic causes of variability in the electrophysiological activity of hearts from individuals of the same species are unknown. However, improved understanding of this variability is key to enable prediction of the response of specific hearts ...

Cardiac Memory-induced T-wave Inversions [PDF]

, 2020
Introduction: Cardiac memory refers to T-wave inversions that result when normal ventricular activation resumes following a period of abnormal ventricular activation.Case Report: We present a case of a 29-year-old man with a pacemaker who presented with ...

Durability of pulmonary vein isolation following cryoballoon ablation: Lessons from a large series of repeat ablation procedures

International Journal of Cardiology: Heart & Vasculature, 2022
Introduction: The second-generation cryoballoon (CB) has emerged in the last decade as an effective treatment for atrial fibrillation (AF). This study sought to analyze the rate of PV reconnection following CB ablation, evaluate the most frequent PV ...

Indeterminacy of Spatiotemporal Cardiac Alternans

, 2008
Cardiac alternans, a beat-to-beat alternation in action potential duration (at the cellular level) or in ECG morphology (at the whole heart level), is a marker of ventricular fibrillation, a fatal heart rhythm that kills hundreds of thousands of people ...

Dynamics of conduction blocks in a model of paced cardiac tissue [PDF]

, 2005
We study numerically the dynamics of conduction blocks using a detailed electrophysiological model. We find that this dynamics depends critically on the size of the paced region.

Cardiac arrhythmias and pacing [PDF]

Srce i krvni sudovi, 2012
In the last two years, a number of land-mark clinical trials have been published which further our understanding and clinical management of patients with atrial fibrillation (AF). Two of the major goals in the treatment of this condition include reducing pro-gression or recurrence of the arrhythmia and decrea-sing the risk of cardiovascular events ...
