Renal denervation with cryoenergy as second-line option is effective in the treatment of resistant hypertension in non-responders to radiofrequency ablation

摘要

Aims: Renal denervation (RDN) with radiofrequency (RF) is being used to treat resistant hypertension (rHTN). As 15-30% of treated patients are non-responders to RDN, we investigated whether RDN with cryoenergy can serve as a second-line option.Conclusions: The significant reduction in systolic OBP and ABP observed qualifies RDN with cryoenergy as an effective second-line therapeutic option in non-responders to RDN with RF.
