Endovascular implantation of a bovine pericardium valve sutured on a self-expandable stent was technically feasible, achieving precise implantation without migration in 8 of 14 sheep (57.1%).
Is percutaneous implantation of a bovine pericardium valve sutured on a self-expandable stent technically feasible in a sheep model?
This early preclinical study demonstrated the technical feasibility of percutaneous aortic valve implantation using a self-expandable stent in a sheep model.
Recently, percutaneous aortic valve implantation has become an alternative technique to surgical valve replacement in patient at high risk for surgery. Our animal experimentation evaluated the technical feasibility of aortic valve replacement using a bovine pericardium valve sutured on a self-expandable stent in a sheep model. Precise implantation with satisfactory attachment on the adjacent tissues and absence of migration was obtain in 8 out of 14 animals. This study confirmed the feasibility of the endovascular implantation of a pericardium valve sutured on a self-expandable stent in a sheep model.
Laborde et al. (Fri,) conducted a other in Aortic valve replacement (n=14). Percutaneous aortic valve implantation (bovine pericardium valve on a self-expandable stent) was evaluated on Technical feasibility (precise implantation with satisfactory attachment and absence of migration). Endovascular implantation of a bovine pericardium valve sutured on a self-expandable stent was technically feasible, achieving precise implantation without migration in 8 of 14 sheep (57.1%).
