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

ABSTRACT:

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. Finally, we determined operating times, echocardiography and changes of coronary flow as well as fenestration alignment with the coronary ostia.

Results

This approach resulted in a 100% overall technical success rate, excellent handling properties and preci
