Abstract

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice, with increasing incidence globally. RF ablation is a common treatment for AF, attempting to interrupt aberrant electrical patterns. The success rate of this procedure is suboptimal (∼60%), with a substantial amount of patients needing reintervention [1]. Providing the surgeon with real time feedback on lesion formation could increase the efficacy of this procedure [2]. We consider visible contrast in the lesion and routine intracardiac echography (ICE) guidance, to put forward photoacoustic/ultrasound imaging (PAUS) as a means to visualize the lesion. The objective of this study is to identify the optimum illumination wavelengths for lesion contrast and imaging depth [3].
