Successful intravascular lithotripsy after all other options failed with stent under-expansion: a case report and review of alternative options.

ABSTRACT:

Background

Stent under-expansion, often caused by severe circumferential coronary calcification, must be prevented as it increases the risk of neoatherosclerosis and stent thrombosis. Intravascular lithotripsy (IVL) is an effective lesion preparation strategy to enable sufficient expansion of a stent that was initially not sufficiently expanded.

Case summary

A 62-year-old male patient presented in our emergency department due to unstable angina. Coronary angiography revealed one-vessel coronary artery disease with high-grade stenosis of the proximal to mid right coronary artery. Direct implantation of a drug-eluting stent was performed. However, stent under-expansion was noticed. Post-dilatation with semi-compliant balloon up to 24 bar was unsuccessful. Subsequent dilatation
