Article Synopsis
- Pulsed field ablation (PFA) is a new method for treating atrial fibrillation (AF) that focuses on ablating heart tissue while minimizing harm to nearby structures.
- In the MANIFEST-17K study, data from 106 centers involved 17,642 patients and showed no serious complications like esophageal damage, with only a 1% major complication rate.
- The results suggest that PFA has a strong safety profile and may change how AF is treated, compared to traditional thermal ablation methods.
Modern drug formulations often require, besides the active drug molecule, auxiliaries to enhance their pharmacological properties. Tailor-made, biocompatible polymers covalently connected to the drug molecule can fulfill this function by increasing its solubility, reducing its toxicity, and guiding it to a specific target. If targeting membrane-bound proteins, localization of the drug close to the cell membrane and its target is beneficial to increase drug efficiency and residence time.

Background: Catheter ablation of paroxysmal atrial fibrillation (AF) can be performed under general anesthesia or conscious sedation. The influence of type of anesthesiology care on procedural characteristics and ablation outcome in patients in whom intracardiac echocardiography (ICE) and elimination of adenosine-mediated dormant conduction (DC) is used is not entirely known.
Methods: 150 patients with paroxysmal AF were randomized to point-by-point radiofrequency catheter isolation of pulmonary veins (PVI) under general anesthesia (n=77) or conscious sedation (n=73).
Background: The impact of ECG gating during computed tomography (CT) acquisition of left atrium (LA) model on radiation dose, image quality and ablation event-free survival rate after catheter ablation (CA) of atrial fibrillation (AF) is not well defined.
Methods: Sixty-two patients with paroxysmal atrial fibrillation were randomized for two types of LA CT (with vs without ECG gating) before CA. Pulmonary veins isolation was performed in all patients.
