New stent design for autologous venous graft-covered stent preparation: first human application for sealing of a coronary aneurysm.

In this case report, we present the first clinical application of a new stent design for autologous venous graft-covered stent preparation. This stent consists of a main body, resembling the configuration of conventional stents, and two connecting arms at the edges of the stent for the stabilization of the venous graft on the external surface of the stent. This new stent design was applied in a patient with an aneurysm in a stented segment in the right coronary artery. The immediate and long-term angiographic evaluation after the covered stent implantation showed complete sealing of the aneurysm without restenosis.
