Successful calcium modification of a large calcified nodule using shockwave intravascular lithotripsy in the setting of acute coronary syndrome: a case report.

ABSTRACT:

Background

Calcified nodules are associated with suboptimal preparation before stenting due to challenging crossing and unsuccessful pre-dilation and calcium cracking with conventional balloons. In this scenario, we report the use of shockwave intravascular lithotripsy for the successful lesion preparation of an undilatable and challenging calcified nodule in a patient presenting with ACS.

Case summary

We report a case of a 79-year-old male patient presented with non-ST elevation myocardial infarction. Coronary angiography revealed 90% stenosis in the proximal segment of the right coronary artery, with a hazy area of inhomogeneous contrast. Intravascular ultrasound (IVUS) imaging identified a large eccentric calcified nodule, with a minimum luminal area (MLA) of 4.18 mm
