Left Atrium Sphericity and Catheter Ablation Outcome in Atrial Fibrillation Patients: A Single-center Cross-sectional Study

open access: yesResearch in Cardiovascular Medicine
Introduction: Catheter ablation is becoming an increasingly utilized treatment option for atrial fibrillation (AF) due to its proven efficacy. This study aims to examine the correlation between changes in left atrium (LA) sphericity and the outcomes of ...

Monomorphic Ventricular Arrhythmias in Athletes. [PDF]

open access: yes, 2019
Ventricular arrhythmias are challenging to manage in athletes with concern for an elevated risk of sudden cardiac death (SCD) during sports competition. Monomorphic ventricular arrhythmias (MMVA), while often benign in athletes with a structurally normal

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

High-resolution mapping and ablation of recurrent left lateral accessory pathway conduction

open access: yesJournal of Arrhythmia, 2017
Proper localization of the anatomical target during ablation of the accessory pathways (AP) and the ability to detect clear AP potentials on the ablation catheter are crucial for successful AP ablation.

Microbubble Shell Stiffness Engineering Enhances Ultrasound Imaging, Drug Delivery, and Sonoporation

open access: yesAdvanced Materials, EarlyView.
 Shell‐engineered poly(alkyl cyanoacrylate) microbubbles with tunable stiffness improve ultrasound imaging and therapy. Adjusting the length of the alkyl chain and the glass transition temperature maintains a narrow microbubble size distribution while enhancing drug loading, sonoporation and the acoustic response.

Long-term clinical outcomes of catheter ablation in patients with atrial fibrillation predisposing to tachycardia-bradycardia syndrome: a long pause predicts implantation of a permanent pacemaker

open access: yesBMC Cardiovascular Disorders, 2018
Background There is a controversy as to whether catheter ablation should be the first-line therapy for tachycardia-bradycardia syndrome (TBS) in patients with atrial fibrillation (AF).

Principal component analysis of atrial fibrillation: Inclusion of posterior ECG leads does not improve correlation with left atrial activity [PDF]

open access: yes, 2015
Background Lead V? is routinely analysed due to its large amplitude AF waveform. V? correlates strongly with right atrial activity but only moderately with left atrial activity. Posterior lead V? correlates strongest with left atrial activity.

Magnetic Milli‐Spinner for Robotic Endovascular Surgery

open access: yesAdvanced Materials, EarlyView.
The magnetic milli‐spinner, with its unique structural design, achieves rapid and stable navigation through complex vasculature at speeds up to 23 cm·s−1. It further enables multifunctional treatment, including localized suction and shear for efficient clot removal, targeted drug delivery, and in situ embolization for aneurysm therapy, establishing it ...
