Use of Coronary Intravascular Lithotripsy: A Comprehensive Review of Literature

Severe coronary artery calcification (CAC) is associated with high rate of procedural complications. The current techniques that facilitate percutaneous coronary interventions in moderate to severe CAC have significant risk of complications, including periprocedural myocardial infarction, dissection, perforation and transient atrioventricular block. Coronary Intravascular lithotripsy (IVL) is a novel technology for the treatment of moderate to severe calcified lesions. IVL uses sonic pressure waves to break down the calcium deposits with no to minimal impact on the blood vessel tissues, which makes IVL a safe option with high procedural success and minimal complications. Here, we discuss coronary IVL as a treatment option for CAC and summarize the major clinical trials performed evaluating the safety and outcome of IVL.
