Background: Arrhythmias originating from papillary muscles (PAPs) can be challenging when targeted with catheter ablation. The prevalence and impact of structural abnormalities on PAPs in patients with focal PAP arrhythmias is unknown.
Objectives: The purpose of this study was to analyze, in a consecutive patient series with focal PAP arrhythmias, the impact of structural abnormalities detected by multimodality imaging.
Article Synopsis
- - Dofetilide, a class III antiarrhythmic, is used to treat atrial fibrillation and flutter, and has been applied off-label for ventricular arrhythmias like PVCs and VTs.
- - In a study involving 81 patients, dofetilide initiation showed a significant decrease in PVC burden, but was discontinued in some cases due to QT prolongation and lack of efficacy.
- - Overall, 72% of patients had to stop dofetilide due to inefficacy or intolerance, and there was no significant difference in event-free survival between those treated with dofetilide and those who weren't.
