VIVA 23 - We are joined by Dr Mahmood Razavi (St. Joseph Heart & Vascular Center, Orange, CA, US) to discuss the findings from an early feasibility study of non-invasive therapeutic ultrasound (TUS) to treat chronic limb-threatening ischemia.

12 patients were enrolled in the trial, who had Rutherford class 3, 4 or 5 peripheral arterial disease. Participants received 30-40 TUS treatment sessions over two months.

Findings suggested that the therapy was tolerable and acceptable to patients. A 17% improvement in tissue oxygenation was also observed.

Interview Questions:

1. What are the unmet needs of PAD patients in 2023?
2. What was the patient population and study design?
3. What are the key findings?
4. What are your take-home messages?

Recorded remotely from Orange, 2023.
