Endovascular treatment of intracranial aneurysms can be technically difficult when the neck is wide. The Solitaire AB stent, the only fully retrieved stent, assists in the coiling of wide-neck intracranial aneurysms. To evaluate the mid-term angiographic follow-up of wide-necked aneurysms treated with the Solitaire AB stent. SOLARE is a consecutive, ...

The introduction of effective and durable leaflet repair techniques have enabled repair of the regurgitant aortic valve. Aortic valve repair is favored to avoid the placement of a prosthesis that the patient will likely outgrow. Furthermore, repair has the potential to reduce the incidence of prosthesis-related complications, including endocarditis, thromboembolism, ...
