Transcatheter aortic valve repair for aortic regurgitation with the Cusper device

Figure 1. The Cusper preclinical proof-of-concept study. A) The Cusper device. B) Delivery system capsule. C-F) Ex vivo model: en face view of a porcine aortic valve with aortic regurgitation induced by aortic root dilatation with and without the device at systolic and diastolic phases. G) Computed tomography planning: on the left – an en face view of the aortic valve post annular alignment and positioning of the axis in an overlap (of the RCC and LCC) view. The upper right figure shows the implantation angle and the delivery capsule superimposed on the image to provide exact implantation depth. H-I ...
