Tight lesion in underexpanded stent: a contemporary approach based on delayed intravascular lithotripsy

Abstract

A patient with massive calcification of the coronary arteries and an unexpanded coronary stent is reported. Due to the persistence of Canadian Cardiovascular Society class III angina, many endovascular treatment techniques were attempted, but most of them were ineffective. Full expansion of the previously implanted stent and resolution of the lesion in the circumflex artery was finally achieved with the use of intracoronary lithotripsy. After successful treatment, the patient is under the care of a cardiology clinic and remains asymptomatic.
