Background
Intravascular lithotripsy (IVL) is increasingly used for treatment of coronary artery calcification. This study aimed to evaluate contemporary utilisation patterns, safety and efficacy of IVL in an unselected real-world patient cohort.
Methods
We included 454 patients undergoing IVL from May 2019 to February 2024 across seven centres in two European countries. Key endpoints included device success, technical success, procedural success, IVL-related complications and major adverse cardiovascular events (MACE) at 1-year follow-up.
Results
The cohort (mean age 73±9 years, 75% male) had a mean SYNTAX Score of 22.0±13.6. Device, technical and procedural success were achieved in 98%, 91% and 89% of patients, respectively. IVL-related complications occurred in six patients (1%). At 1-year follow-up, MACE was observed in 37 patients (13%). Over time, IVL use increased in patients with acute coronary syndrome (p=0.004) and in combination with intracoronary imaging (p=0.002), while use of other calcium modification devices decreased (p=0.034).
Conclusion
In this real-world registry, IVL demonstrated efficacy across diverse clinical and anatomical settings. High success rates, low complication rates and MACE rates were observed acutely and at 1-year follow-up. Utilisation patterns evolved over time, with increased adoption in acute scenarios and alongside intracoronary imaging.
