Article Synopsis
- - Patients with tachycardia-induced cardiomyopathy (TIC) show better left atrial (LA) health, evidenced by lower LA volume, higher voltage, and fewer low-voltage zones (LVZs) compared to those without TIC.
- - In a study of 139 persistent atrial fibrillation patients undergoing catheter ablation, those with TIC had less atrial remodeling and a 36-month follow-up showed no significant difference in the rate of atrial tachyarrhythmia (AT) recurrence between TIC and non-TIC groups.
- - Overall, the findings suggest TIC patients have similar, if not improved, outcomes following ablation procedures, despite possessing a less remodeled atrial substrate.
Background: CHADS-VASc score-related differences have been reported in atrial fibrotic remodeling and prognosis of atrial fibrillation (AF) patients after ablation. There are currently no data on the efficacy of low voltage zone (LVZ)-guided ablation in persistent AF patients according to CHADS-VASc score. We assessed in a cohort of persistent AF patients the extent of LVZ, the regional distribution of LA voltage and the outcome of LA voltage-guided substrate ablation in addition to PVI according to CHADS-VASc score.

We assessed in persistent AF the regional distribution of left atrial (LA) bipolar voltage and the extent of low-voltage zones (LVZ) according to gender as well as the results of a voltage-guided substrate ablation.
Methods: Consecutive patients who underwent a voltage-guided AF ablation were enrolled.
Background: Spontaneous coronary artery dissection (SCAD) is still an underdiagnosed condition that requires a detailed assessment of angiographic signs. It also shares similar clinical presentations with Takotsubo syndrome (TTS). The concomitant presentation of SCAD with TTS is a possible occurrence, making it difficult for clinicians to treat and manage.
