We report a case with exaggerated stent protrusion from the right coronary ostium into the aorta leading to recurrent inferoposterior and right ventricular myocardial infarctions due to stent thrombosis, which were treated successfully with fibrinolysis. The stent was removed via transverse aortotomy and two bypass grafts were performed. Stents protruding from the aorta may not only cause technical difficulties but also carry a high risk of thrombosis.

Dual antiplatelet therapy (DAPT) is essential in the treatment of patients with acute coronary syndrome (ACS). The objective of this study was to evaluate the effectiveness of antiplatelet medication in our practice and to investigate the factors that influence it. A prospective cohort observational study was conducted, in which 193 patients with ACS were enrolled.

Symptomatic femoropopliteal occlusive disease has been increasingly treated using endovascular methods. However, restenosis, especially after implantation of permanent metallic stents, has remained common. To date, resorbable scaffolds have failed to achieve sufficient radial strength to enable the successful treatment of long, mobile, peripheral arteries.

Background: Restenosis in first-generation (single-layer) carotid stents (FGS) is believed to represent an exaggerated healing response of (neo)intimal hyperplasia (NIH) formation. Rather than NIH, we describe symptomatic in-FGS unstable plaque (neo)atherosclerosis mandating re-revascularization. To halt continued plaque evolution, we propose a novel treatment strategy involving a microNet-covered stent (MCS, second-generation carotid stent) to sequestrate the plaque from the vessel lumen.

Stent fracture is a rather infrequent complication associated with in-stent restenosis, thrombosis, aneurysm formation, and ischemic events. Several stent-related parameters, such as the use of longer or multiple stents, stent overlapping, and balloon/stent overexpansion are potential predictors of stent fracture. Stents deployed in right coronary artery lesions with exaggerated motion, tortuosity, or severe calcification are also generally considered to be at higher risk for fracture.
