Direct comparison of two 50 W high power short duration approaches—Temperature‐ versus ablation index‐guided radiofrequency ablation for atrial fibrillation

Journal of Cardiovascular Electrophysiology, Volume 33, Issue 12, Page 2517-2527, December 2022., 2022
Abstract Introduction Approaches applying higher energy levels for shorter periods (high power short duration, HPSD) to improve lesion formation for atrial fibrillation (AF) ablation have been introduced. This single‐center study aimed to compare the efficacy, safety, and lesion formation using the novel DiamondTemp (DT) catheter or an ablation index ...

Wide and narrow QRS tachycardias: What is the mechanism?

Indian Heart Journal, 2020
A 50-year-old lady was referred for radiofrequency catheter ablation of narrow QRS tachycardia that was terminated with intravenous adenosine. Twelve-lead Electrocardiogram (ECG) was normal during sinus rhythm.

Severity of tricuspid regurgitation predicts risk of recurrence of atrial fibrillation after pulmonary vein isolation

ESC Heart Failure, EarlyView.
Abstract Aims Tricuspid regurgitation (TR) results in right atrial remodelling, thus promoting the formation of a substrate for atrial fibrillation (AF). In turn, AF may cause TR by annulus dilatation. We investigated whether the presence of TR affects the efficacy of pulmonary vein isolation (PVI) for AF. Methods and results In patients undergoing PVI,

Impact on right ventricular performance in patients undergoing permanent pacemaker implantation: Left bundle branch pacing versus right ventricular septum pacing

Journal of Cardiovascular Electrophysiology, Volume 33, Issue 12, Page 2614-2624, December 2022., 2022
Abstract Background The novel method of left bundle branch pacing (LBBP) has been reported to achieve better electrical and mechanical synchrony in the left ventricle than conventional right ventricular pacing (RVP). However, its effects on right ventricle (RV) performance are still unknown.

AV‐node isolation as an alternative to AV‐node ablation in patients undergoing pace & ablate strategy

Journal of Cardiovascular Electrophysiology, Volume 33, Issue 12, Page 2606-2613, December 2022., 2022
Abstract Introduction Atrioventricular (AV)‐node ablation (AVNA) is a common therapy option for rate control strategy of permanent atrial fibrillation (AF). We hypothesized that isolation of the AV nodal isolation (AVNI) is associated with a more frequent preservation of an adequate escape rhythm compared to AVNA.

Fluid dynamics of heart valves during atrial fibrillation: a lumped parameter-based approach [PDF]

, 2015
Atrial fibrillation (AF) consequences on the heart valve dynamics are usually studied along with a valvular disfunction or disease, since in medical monitoring the two pathologies are often concomitant. Aim of the present work is to study, through a stochastic lumped-parameter approach, the basic fluid dynamics variations of heart valves, when only ...

User-initialized active contour segmentation and golden-angle real-time cardiovascular magnetic resonance enable accurate assessment of LV function in patients with sinus rhythm and arrhythmias. [PDF]

, 2015
BackgroundData obtained during arrhythmia is retained in real-time cardiovascular magnetic resonance (rt-CMR), but there is limited and inconsistent evidence to show that rt-CMR can accurately assess beat-to-beat variation in left ventricular (LV ...

Health‐related quality of life across heart failure categories: associations with clinical characteristics and outcomes

ESC Heart Failure, EarlyView.
Abstract Aims The study aims to examine characteristics and outcomes associated with health‐related quality of life (HRQoL) in patients with heart failure (HF) with preserved, mildly reduced and reduced ejection fraction (EF) (HFpEF, HFmrEF and HFrEF). Methods and results Data on HRQoL were collected in the Swedish Heart Failure Registry (SwedeHF; 2000–
