Key result
IVUS-guided stent crush technique successfully manages stent crumpling to restore TIMI III flow during PCI.
Why the study?
Stent crumpling is a rare but potentially life-threatening complication of PCI that requires recognition and management strategies.
Case Report (n=1)
Intravascular imaging such as IVUS is essential for the prompt diagnosis and successful management of rare, life-threatening mechanical complications like stent crumpling during PCI.
IVUS may aid rare PCI complication management; leaves open whether routine use improves outcomes.
Stent crumpling is a rare but potentially life-threatening complication of percutaneous coronary intervention (PCI). This report highlights a case of stent crumpling during a PCI procedure, its management, and the importance of advanced imaging techniques in diagnosing and addressing such complications. A 78-year-old man was admitted for elective PCI on the left anterior descending (LAD) artery following an acute anterior ST-segment elevation myocardial infarction (STEMI) treated with thrombolytic therapy. The patient exhibited significant ischemic changes on his electrocardiogram (ECG) and experienced persistent angina. During the PCI, two overlapping stents were deployed in the LAD. Post-dilation led to slow flow and thrombus formation in the LAD, rapidly progressing to cardiac arrest. Immediate resuscitation and intracoronary thrombolytic therapy were initiated. Intravascular ultrasound (IVUS) revealed stent crumpling, so the proximal stent folded within the vessel lumen. To solve this issue, the crumpled stent was crushed behind a newly deployed stent, followed by post-dilation, which restored TIMI flow grade III in the LAD.

Mehrpooya et al. (2025) conducted a case report in Stent crumpling during percutaneous coronary intervention (n=1). Intravascular ultrasound (IVUS) and stent crushing technique was evaluated on Restoration of coronary blood flow (TIMI flow grade III). Intravascular ultrasound identified stent crumpling during PCI, which was successfully managed by crushing the crumpled stent behind a newly deployed stent to restore TIMI flow grade III.
