Comparison of Myocardial Perfusion Reserve Before and After Coronary Balloon Predilatation and After Stent Implantation in Patients With Postangioplasty Restenosis

Abstract

Coronary stent implantation in patients with postangioplasty restenosis normalized poststenotic myocardial perfusion immediately as a result of a larger postprocedural lumen and a more pronounced inhibition of elastic recoil. After 6 months this benefit was sustained despite progressive lumen loss.
