title: An accordion phenomenon with ST-segment elevation of electrocardiogram and anginal chest pain: a case report.
abstract: Tortuous coronary arteries frequently make percutaneous coronary intervention (PCI) difficult by causing less accessibility of guidewire toward the target lesion. After guidewire has been passed through the target lesion, it often assists a balloon catheter and stent system insertion along the stiff guidewire. However, artificial kinking and wrinkling might induce pseudo-narrowing of coronary arteries, which has been recognized as an "accordion phenomenon." We describe an educational case of an accordion phenomenon with ST-segment elevation of electrocardiogram and anginal chest pain when the stiff guidewire which had been withdrawn was advanced again into the distal site after deploying stents.
