Intravascular imaging–guided intracoronary lithotripsy: First real‐world experience

Abstract

Abstract Background and Aims Coronary calcification remains a significant challenge for the contemporary interventional cardiologist. We aim to describe the use of intravascular lithotripsy (IVL) in a range of real‐world settings. Methods A retrospective two‐center analysis of patients treated with IVL between June 2018 and November 2019. Technical and procedural success, as well as procedural complications and 30‐day outcomes (death, myocardial infarction, or repeat target vessel revascularization), was recorded. Results Sixty‐five patients underwent IVL: 80% were male and the mean age was 70.1 ± 12.0 years. 54% of patients presented with acute coronary syndrome (ACS) and 68% of patients had intracoronary imaging. Twelve patients required IVL within pre‐existing stents, and 12 underwent IVL in the left main stem. All balloons were successfully delivered with 98.5% procedural success. There was a significant gain in MLA post PCI of 261.9 ± 100% following IVL. There were two procedural complications. At 30‐day follow‐up, there was one death, and one patient required a repeat procedure due to stent underexpansion. Conclusions In this largest real‐world series of imaging‐guided IVL for calcified lesions to date, we demonstrate that IVL is deliverable, safe, and effective at calcium modification especially when intracoronary imaging is used.
