The accordion phenomenon of the left anterior descending(LAD) artery

Accordion phenomenon , during routine angioplasty procedure, is produced by mechanical alteration of the geometry and curvature of a tortuous vessel by stiff PCI wire, resulting in invagination and shortening of the vessel wall. It has been described in all coronary arteries and left internal mammary artery graft but left anterior descending is very rare. Given the possible serious alternative diagnoses there cognition of the accordion effect is important and may prevent unnecessary interventions. [Cukurova Med J 2013; 38(2.000): 325-328]
