Acoustic Shock Waves to Modify Calcific Plaques - Intravascular Lithotripsy in the Peripheral Circulation.

ABSTRACT

Intravascular lithotripsy (IVL) is a new technique for treatment of severely calcified lesions that uses acoustic shockwaves in a balloon-based system to induce fracture in calcific plaque, facilitating luminal gain and vessel expansion. In this review, we provide a concise summary of the available data and clinical experience of IVL in various peripheral vascular beds, including facilitating vascular access for large-bore devices. We discuss the physics and mode of action of IVL in modifying calcified plaques, include several illustrative examples of utility of IVL in peripheral interventions, and discuss the future directions for adoption of the technique in peripheral interventions.
