The nsPFA exhibited noninferior efficacy & comparable safety to #AI-guided RFA while obviating the need for general anesthesia. The study also revealed that this ablation technique sig. 📉 both total procedure time & left atrial dwelling time. https://t.co/g6lZshouUU #JACC

Ventricular arrhythmias in association with athletic cardiac remodelling
Review #EUROPACE @ESC_Journals

"It is unclear whether the ‘athlete’s heart’ promotes specific arrhythmias or whether it represents a more general pro-arrhythmogenic phenotype"

Focused summary on the "Use of hiPSC-Derived Cardiomyocytes for #Cardiotoxicity Screening":
1. #hiPSC-CM = great alternative to in vivo models for drug cardiotoxicity prediction
2. Monolayers = for pro-arrhythmic effects; inotropic actions need more exploration
3. Spheroids & engineered tissue = promising for chronic cardiotoxicity studies
4. Paracrine effects = crucial; assays mimicking non-myocyte cells can ID cardiotoxicity
5. Future = Patient-specific assays!

Esta reducción de volumen se asoció con reducción de recurrencia de arritmia, reducción de la carga de FA y mejoría en la FEVI y la calidad de vida
