ABSTRACT

Phototherapy (PT), including photodynamic therapy (PDT) and photothermal therapy (PTT), has recently achieved significant advances in antitumor and antiinfection therapy. Sonodynamic therapy (SDT), as a novel noninvasive therapy with a deeper penetration depth (>8 cm), fewer side effects and non-phototoxicity than PT, has drawn much attention in recent years. However, both PT and SDT have intrinsic limitations. By combining PT with SDT, the dualmodel therapy with advanced sensitizers overcome the intrinsic limitations and show higher efficacy than traditional monotherapy. Moreover, the photo-diagnosis modality could be easily integrated into synergistic therapy so that the sensitizer acts as a tracer for fluorescence/photoacoustic imaging, and the treatment process is visualized in a way that SDT combined with other therapies cannot achieve. This review summarizes the advanced sensitizers and the application of combination therapy, and explores the improvement strategies for promoting clinical transformation.

ABSTRACT

BACKGROUND: Three-dimensional electroanatomic mapping systems have demonstrated a significant reduction in radiation exposure during radiofrequency catheter ablation procedures. We aimed to investigate the safety, feasibility and efficacy of a completely zero-fluoroscopy approach for catheter ablation of supraventricular tachycardia using the Ensite NavX navigation system compared with a conventional fluoroscopy approach. METHODS: A multicenter prospective non-randomized registry study was performed in seven centers from January 2013 to February 2018. Consecutive patients referred for catheter ablation of supraventricular tachycardia were assigned either to a completely zero-fluoroscopic approach (ZF) or conventional fluoroscopy approach (CF) according to the operator's preference. Patients with atrial tachycardia were excluded. RESULTS: Totally, 1020 patients were enrolled in ZF group; 2040 patients ablated by CF approach were selected for controls. There was no significant difference between the zero-fluoroscopy group and conventional fluoroscopy group as to procedure time (60.3 ± 20.3 vs. 59.7 ± 22.6 min, P = 0.90), immediate success rate of procedure (98.8% vs. 99.2%, P = 0.22), arrhythmia recurrence (0.4% vs. 0.5%, P = 0.85), total success rate of procedure (98.4% vs. 98.8%, P = 0.39) or complications (1.1% vs. 1.5%, P = 0.41). Compared with the conventional fluoroscopy approach, the zero-fluoroscopy approach provided similar outcomes without compromising the safety or efficacy of the procedure. CONCLUSION: The completely zero-fluoroscopy approach demonstrated safety and efficacy comparable to a conventional fluoroscopy approach for catheter ablation of supraventricular tachycardia, and mitigated radiation exposure to both patients and operators. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT03042078; first registered February 3, 2017; retrospectively registered.
