Summary: | Objectives
To explore the long‐term clinical outcomes following intravascular lithotripsy (IVL) in calcified coronary lesions from a real‐world population.
Background
IVL is a relatively new but promising modality for treating coronary calcified lesions, but there is a dearth of long‐term outcome data from real‐world patients.
Methods
This was a multicenter, observational study in which we enrolled all patients treated with IVL from November 2018 to February 2021 from eight centers in Europe and the United Kingdom. Procedural success, complications, and clinical outcomes (cardiac death, target vessel myocardial infarction [TVMI], target lesion revascularization [TLR], and MACE [major adverse cardiac events, the composite of cardiac death, TVMI, and TLR]) were assessed.
Results
In total, 273 patients with a mean age of 72 ± 9.1 years were treated with IVL. Major comorbidities included diabetes mellitus (n = 110, 40%) and chronic kidney disease (n = 45, 16%). Acute coronary syndrome accounted for 48% (n = 132) of patients, while 52% (n = 141) had stable angina. De novo lesions and in‐stent restenosis accounted for 79% and 21% of cases, respectively. Intravascular imaging was used in 33% (n = 90) of patients. An upfront IVL strategy was adopted in 34% (n = 92), while the rest were bailout procedures. Adjuvant rotational atherectomy (“RotaTripsy”) was required in 11% (n = 31) of cases. The procedural success was 99%. During a median follow‐up of 687 days (interquartile range: 549–787), cardiac death occurred in 5% (n = 14), TVMI in 3% (n = 8), TLR in 6% (n = 16), and MACE rate was 11% (n = 30).
Conclusion
This is the largest multicenter registry with a long‐term follow‐up showing the remarkably high procedural success of IVL use in calcified coronary lesions with low rates of hard endpoints and MACE. |
