Thermal profiles of pulsed field ablation catheters

Heart Rhythm
Pulsed field ablation (PFA) induces cell death predominantly through irreversible electroporation (IRE), a non-thermal mechanism. However, Joule heating during PFA delivery may result in clinically relevant temperature rises.This study aimed to characterize the thermal profiles, peak surface temperatures, and ablation lesions produced by 6 proprietary ...

Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

Advanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Biophysical numerical model for pulsed field ablation

Bioelectrochemistry
Pulsed-Field Ablation (PFA) is a non-thermal technique for the treatment of cardiac arrhythmias. Predictive numerical models capable of reliably predicting lesion size and shape remain limited. We introduce a biophysics-grounded and inherently anisotropic model for cardiac PFA, derived by homogenization of a microscopic electroporation model.
