Wild Type Transthyretin Amyloid Cardiomyopathy Hidden Under Ablation‐Refractory Atrial Arrhythmias and the Potential Contribution of Tafamidis in Rhythm Control

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
An octogenarian man with a history of multiple catheter ablation failures for atrial fibrillation and tachycardia was diagnosed with transthyretin amyloid cardiomyopathy. After 1 year of tafamidis therapy, the patient experienced spontaneous restoration of sinus rhythm, and follow‐up image of 99mTc‐pyrophosphate scintigraphy revealed a marked decrease ...

Ablation of Ventricular Tachycardia Using the QDOT MICRO Ablation Catheter (VT‐MICRO Study)

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
Catheter ablation is useful to treat patients with ventricular tachycardia. QDOT Micro catheter is a next generation catheter designed to provide more efficient lesion creation with an accurate myocardial substrate analysis. Microelectrode mapping allows detection of higher voltage electrograms compared to standard bipolar mapping and Pentaray mapping.

Supraventricular Tachycardias Using Multiple Accessory Pathways

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
Three atrioventricular reciprocating tachycardias (AVRTs) using 3 accessory pathways (APs) occurred with the His bundle eliminated by the previous ablation. Two AVRTs using 2 right APs rotated reversely, and the other AVRT was one with a retrograde conduction through the left AP and anterograde conduction through the 2 right APs.

Outcomes of Pulsed Field Versus Cryoballoon Ablation in Atrial Fibrillation: A Comprehensive Systematic Review and Meta‐Analysis

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
The key findings of this meta‐analysis are as follows: (1) PFA was associated with a significantly shorter duration compared to the CBA group, (2) PFA was associated with a significantly lower rate of arrhythmia recurrence compared with CBA. Yet, the rate of redo ablation did not differ significantly between both groups, (3) The overall complication ...

Temporal Variability and Influence of Measurement Conditions of AI‐Based Atrial Fibrillation Risk Estimation

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
The atrial fibrillation (AF) risk estimated by artificial intelligence‐based program installed in electrocardiography (ECG) machine exhibited temporal variability. Reproducibility within one level of error was 100% for the same ECG, 95% for reproducibility within 4 min interval, and 87% for reproducibility over 15 min interval.
