Abstract

Despite technological evolution, percutaneous coronary interventions targeting coronary calcifications remain challenging and associated with high rates of complications and adverse outcomes. Over the years, rotational atherectomy has emerged as the reference treatment of calcified coronary artery lesions despite some inherent limitations. Also, rotational atherectomy typically requires relatively large guiding catheters which may unfavorably impact on the decision for transradial access, especially when radial artery is small, and consequently offset the relevant clinical benefits associated to transradial access. Recently, a new technology has been introduced in interventional practice to implement coronary lithotripsy. The device implements multiple small emitters enclosed in a coronary balloon creating sonic pressure waves to selectively fracture calcium within the plaque and favorably modify vessel compliance. Owing to its specific design, coronary shockwave lithotripsy could be used with small bore guiding catheters which may allow for straightforward transradial percutaneous treatment of calcified coronary lesions even in patients with a small radial artery. To illustrate this concept, we report the first experience of slender transradial coronary shockwave lithotripsy with a five French sheathless guiding catheter.
