Plaque Prolapse After Stent Implantation in Patients With Acute Myocardial Infarction: An Intravascular Ultrasound Analysis Young Joon Hong, Myung Ho Jeong, Youngkeun Ahn, Doo Sun Sim, Jong Won Chung, Jung Sun Cho, Nam Sik Yoon, Hyun Ju Yoon, Jae Youn Moon, Kye Hun Kim, Hyung Wook Park, Ju Han Kim, Jeong Gwan Cho, Jong Chun Park, Jung Chaee Kang Stenting in arteries with recent plaque rupture has the potential to produce suboptimal results. Intravascular ultrasound (IVUS) imaging found plaque prolapse (PP) in one-fourth of patients after stenting of infarct-related arteries. Lesion characteristics identified by pre-intervention IVUS, such as plaque rupture and positive remodeling, together with longer stent length predicted PP. PP is associated with more myonecrosis after stenting of the infarct-related artery in patients with AMI. Long-term follow-up of PP is pending for correlation with stent complications.
