Atrial amyloidosis: mechanisms and clinical manifestations

European Journal of Heart Failure, Volume 24, Issue 11, Page 2019-2028, November 2022., 2022
Atrial amyloidosis: pathophysiology and clinical manifestations. Atrial amyloidosis can manifest as part of a systemic disorder (as in amyloid light‐chain [AL] or transthyretin [ATTR] amyloidosis), or be isolated (in the form due to atrial natriuretic type [ANP] accumulation); this last form is often associated with permanent or persistent atrial ...

Mutation update for the ACTN2 gene

Human Mutation, Volume 43, Issue 12, Page 1745-1756, December 2022., 2022
Abstract ACTN2 encodes alpha‐actinin‐2, a protein expressed in human cardiac and skeletal muscle. The protein, located in the sarcomere Z‐disk, functions as a link between the anti‐parallel actin filaments. This important structural protein also binds N‐terminal titins, and thus contributes to sarcomere stability.

Confirm Rx insertable cardiac monitor for primary atrial fibrillation detection in high‐risk heart failure patients (Confirm‐AF trial)

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Confirm‐AF is a prospective randomized, nonblinded, two arm, multicenter clinical trial, which will enroll 477 patients with a history of HF hospitalization and left ventricular ejection fraction >35% from 30 medical sites. Patients will be randomized in a 2:1 fashion to receive an implantable cardiac monitor (ICM) with remote monitoring and symptom ...

Paroxysmal supraventricular tachycardia in pregnancy: A case report

Bali Journal of Anesthesiology, 2023
Paroxysmal supraventricular tachycardia (PSVT) is a clinical syndrome characterized by regular tachycardia with sudden onset and termination that includes atrioventricular nodal reentrant tachycardia (AVNRT), atrioventricular reentrant tachycardia (AVRT),

Improved Cardiac Arrhythmia Prediction Based on Heart Rate Variability Analysis [PDF]

, 2022
Many types of ventricular and atrial cardiac arrhythmias have been discovered in clinical practice in the past 100 years, and these arrhythmias are a major contributor to sudden cardiac death. Ventricular tachycardia, ventricular fibrillation, and paroxysmal atrial fibrillation are the most commonly-occurring and dangerous arrhythmias, therefore early ...

Low voltage‐guided ablation of posterior wall improves 5‐year arrhythmia‐free survival in persistent atrial fibrillation

Journal of Cardiovascular Electrophysiology, Volume 33, Issue 12, Page 2475-2484, December 2022., 2022
Abstract Introduction The posterior wall (PW) has been proposed as a standard target for ablation beyond pulmonary vein antral isolation (PVI) in patients with persistent atrial fibrillation (AF). However, studies have shown inconsistent outcomes with the addition of PW ablation.

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 ...

3D mapping of phrenic nerve course for radiofrequency pulmonary vein isolation

Journal of Cardiovascular Electrophysiology, Volume 34, Issue 1, Page 90-98, January 2023., 2023
Abstract Introduction Phrenic nerve (PN) injury is a rare but severe complication of radiofrequency (RF) pulmonary vein isolation (PVI). The objective of this study was to characterize the typical intracardiac course of the PN with a three‐dimensional electroanatomic mapping system, to quantify the need for modification of the ablation trajectory to ...

Does organized atrial tachycardia after a pulmonary vein isolation-only procedure portend better outcome of repeat ablation compared to recurrent atrial fibrillation? [PDF]

J Arrhythm
Previous studies combining pulmonary vein isolation (PVI) with left atrial (LA) substrate modification suggested a better outcome of redo procedures when recurrence presented as organized atrial tachycardia (OAT) compared to recurrent atrial fibrillation (AF), despite the former being associated with more advanced LA remodeling. In our study, employing

Patient-Specific Heart Model Towards Atrial Fibrillation [PDF]

ICCPS 2021: Proceedings of the ACM/IEEE 12th International Conference on Cyber-Physical Systems, 2022
Atrial fibrillation is a heart rhythm disorder that affects tens of millions people worldwide. The most effective treatment is catheter ablation. This involves irreversible heating of abnormal cardiac tissue facilitated by electroanatomical mapping.
