We describe a case of atypical atrial flutter presenting 1 year after radiofrequency ablation for atrial fibrillation (AF). Electrophysiologic study showed a reentry circuit involving the inferolateral aspect of the mitral annulus and the coronary sinus (CS); however, a mitral isthmus line did not terminate the arrhythmia. Participation of the proximal CS musculature in the circuit suggested a possible target for ablation. Radiofrequency energy applications from within the CS terminated the tachycardia. Mapping and ablation within the CS should be considered in patients with post-AF ablation arrhythmias, particularly when the mitral annulus appears to be involved in the tachycardia circuit.

Sotalol, a class III antiarrhythmic agent, is used to maintain sinus rhythm in patients with atrial fibrillation or atrial flutter (AFIB/AFL). Despite its efficacy, sotalol's use is limited by its potential to cause life-threatening ventricular arrhythmias due to QT interval prolongation. Traditionally, sotalol administration required hospitalization to monitor these risks.

Background: Atrial flutter (AFL) is usually effectively treated by cavotricuspid isthmus (CTI) ablation. If AFL recurs despite ablation, there is risk of progression to atrial fibrillation (AF) and clinicians should consider underlying structural heart diseases. This consideration becomes especially critical when right-heart-chambers are dilated.

Article Synopsis
- Autoimmune diseases (ADs) are linked to a higher risk of all-cause mortality in patients with cardiac arrhythmias, particularly atrial fibrillation and ventricular tachycardia.
- The study analyzed data from over 14,000 patients, finding that those with ADs had increased mortality rates after one year of discharge.
- Statistical analyses confirmed these results, highlighting the significant risk associated with ADs in arrhythmia patients, although the association for bradyarrhythmias did not reach statistical significance.

Background: Catheter ablation is a key treatment for atrial fibrillation (AF), with high-power, very high-power short-duration and pulsed field ablation (PFA) being efficient options. However, direct comparisons between these techniques are lacking.
Objective: We performed a systematic review and meta-analysis, which included predominantly observational studies (four retrospective and one prospective study), to compare PFA and High-power short-duration (HPSD) and very high-power short-duration (vHPSD) radiofrequency (RF) ablation in patients with AF.
