Recurrent Coronary In-Stent Restenosis: Potential of Membrane-Covered Stents

Abstract

We report a 64-year-old patient with single vessel coronary disease who initially underwent PTCA and stent implantation for a complex RCA lesion. The patient was subsequently readmitted for unstable angina pectoris after 2 and 6 months. Coronary angiograms each time revealed subtotal reocclusions of the target vessel due to in-stent restenosis. At 2 months, the patient underwent rotational atherectomy and additional stent implantation, During the second reintervention at 6 months rotational atherectomy was followed by implantation of two membrane-covered stent deployed within the conventional stents (stent-indent). Subsequently, the patient remained asymptomatic. Control angiography after 5 months revealed only minor stent lumen loss not requiring reintervention. Membrane-covered stents appear to be a promising alternative to reduce the incidence and degree of in-stent restenosis in selected lesions.
