Chimney Graft Technique Combined With Embolization for Treating Ruptured Aortic Arch Lesions.

This study aimed to share the experience in applying the chimney graft technique combined with embolization for treating aortic arch rupture under emergency conditions and evaluating early-term results in these patients. This study retrospectively included patients with ruptured aortic arch lesions who received the chimney graft technique combined with embolization between March 2016 and March 2021. The primary endpoint was a technical success, deemed as successful stent graft deployment to the planned location, patency of the target branch vessel, and absence of significant type I endoleak.

Simultaneous transcatheter treatment of ascending aortic aneurysm with aortic and mitral regurgitation: an in vitro study.

Objectives: We sought to explore the efficacy of the endovascular repair of an ascending aortic aneurysm with aortic and mitral regurgitation by 2 novel valved stents.

Methods: We established models of ascending aortic aneurysms combined with aortic and mitral regurgitation in 10 pig hearts, then implanted self-expanding aortic fenestrated and mitral valved stents via the transapical approach. We applied a fluoroscopy-guided in vitro setting to test the approach, then analysed continuous circulating flushing at 37°C.
