Accordion Phenomenon: A Rare Cause of Acute Total Occlusion During Percutaneous Coronary Intervention
Placement of stiff guidewires through tortuous coronary arteries allows smooth advancement of stents during coronary intervention. However, the straightening of coronary vessels leads to a mechanical alteration and induces vessel wall shortening. The transient effect of such coronary pseudo-stenosis is referred as "accordion phenomenon". This case described the accordion phenomenon after placement of a stiff guidewire through a tortuous right coronary artery leading to acute total occlusion with ST elevation during coronary intervention.
