Article Synopsis
- Pulsed field ablation (PFA) is a new treatment for atrial fibrillation (AF) that shows strong safety and efficacy by specifically targeting heart muscle cells while sparing nearby tissues.
- A meta-analysis comparing PFA with cryoballoon ablation (CRYO) found that PFA had higher procedural success rates and fewer complications, along with shorter procedural and fluoroscopy times.
- However, there were no significant differences in major complications or freedom from atrial tachyarrhythmias after one year between the two techniques.
Article Synopsis
- Pulsed field ablation (PFA) is a new technique for heart tissue treatment that targets heart cells directly without damaging nearby tissues, but using it with mechanical heart valves can be tricky due to potential interference.* -
- This study involved 30 patients with mechanical heart valves undergoing PFA for atrial fibrillation, and it found no major complications, with normal valve function post-procedure.* -
- While PFA seems safe for patients with mechanical valves, careful management of the catheter is crucial to prevent electromagnetic interference that could affect the treatment.*
Introduction: Ultrasound-guided (Echo-AVP) and Fluoroscopy-guided Axillary Vein Puncture (Fluoro-AVP) are both acknowledged as safe and effective techniques for transvenous implantation of leads for cardiac implantable electronic devices (CIEDs). Nonetheless, it is still debated which of the two techniques has a better safety and efficacy profile. Therefore, we performed a meta-analysis to evaluate the efficacy and safety of Echo-AVP versus Fluoro-AVP for CIEDs implantation.

Background: Stereotactic arrhythmia radioablation (STAR) was introduced to treat ventricular tachycardia (VT) refractory to catheter ablation. No data are now available in the septal VT substrate setting, representing a challenge when using conventional techniques.
Objectives: This study sought to evaluate the arrhythmic burden in patients with septal VT treated with magnetic resonance-guided STAR (MRgSTAR).
Background: Newly generated cardiomyocytes (NGCs) concur with the recovery of human myocarditis occurring spontaneously in around 50% of cases. However, NGCs decline with age, and their modality of myocardial homing and integration are still unclear.
Methods: We retrospectively assessed NGCs in 213 consecutive patients with endomyocardial biopsy denoting acute myocarditis, with normal coronaries and valves.
