Abstract:
In high-risk patients with diseases of the ascending aorta, endovascular repair might be a therapeutic alternative to surgical repair. We developed a combined access route with transapical and transfemoral externalization of the wire and report the operative technique as well as our initial experience of six patients treated with this method. Improved wire control resulted in precise deployment of endovascular prostheses, respecting the integrity of the coronary ostia and the supra-aortic vessels. Procedural success was 100%, and follow-up until 32 months postoperatively showed no need for reintervention or mortality. However, long-term results of the presented technique are still unknown.
