EXpansion of Stents After Intravascular lithoTripsy Versus Conventional Predilatation in CALCified Coronary Arteries - EXIT-CALC
Contribution To Literature:
The EXIT-CALC trial failed to show that intravascular lithotripsy improves stent expansion in calcified coronary arteries.
The goal of the trial was to evaluate intravascular lithotripsy compared with balloon angioplasty among patients with severe coronary artery calcium undergoing percutaneous coronary intervention (PCI).
Patients with severe coronary artery calcium undergoing PCI were randomized to intravascular lithotripsy (n = 19) versus balloon angioplasty (n = 21).
- Patients with severe coronary artery calcium undergoing PCI
The primary outcome, stent expansion, was 83.9% in the intravascular lithotripsy group vs. 82.2% in the balloon angioplasty group (p = 0.63).
In this small trial, there was no difference in stent expansion with intravascular lithotripsy compared with balloon angioplasty in calcified coronary arteries. Larger trials are required to determine the impact of intravascular lithotripsy on clinical events.
