Bioprosthetic Aortic Valve Fracture During Valve-in-valve Transcatheter Aortic Valve Implantation
Login or register to view PDF. Abstract The limited durability of surgical bioprostheses, combined with an ageing population, has led to an increasing demand for replacing degenerated bioprosthetic surgical heart valves, which is projected to increase. Valve-in-valve transcatheter aortic valve implantation involves implanting a transcatheter heart valve within a degenerated bioprosthetic surgical heart valve.

Impact of Mitral Regurgitation on Clinical Outcomes After Transcatheter Aortic Valve Implantation
Aortic stenosis (AS) is the most frequent form of valvular heart disease referred for surgery in Europe and is the second most prevalent form of valvular heart disease in the US.1,2 Conversely, moderate or severe mitral regurgitation (MR) is the most prevalent valvular disease in the US and the second most common form of valvular heart disease requiring surgery in Europe.1,2 AS and MR frequently coexist and the prevalence of both valvular lesions increases with age.2,3 While AS imposes a...
Can We Predict Quality of Life and Survival After Transcatheter Aortic Valve Replacement?
Transcatheter aortic valve replacement (TAVR) has been shown to dramatically improve survival and quality of life for many patients with symptomatic severe aortic stenosis (AS) considered inoperable or at high risk for conventional surgical aortic valve replacement.1–5 In fact, recent analyses from 2 separate randomized controlled trials have reported that health-related quality of life improves earlier and faster among high-risk patients assigned to transfemoral TAVR, as compared with...
Effect of Pulmonary Hypertension Hemodynamic Presentation on Clinical Outcomes in Patients With Severe Symptomatic Aortic Valve Stenosis Undergoing Transcatheter Aortic Valve Implantation
Methods and Results—Of 606 consecutive patients undergoing TAVI, 433 (71.4%) patients with severe aortic stenosis and a preprocedural right heart catheterization were assessed. Patients were dichotomized according to whether PH was present (mean pulmonary artery pressure, ≥25 mm Hg; n=325) or not (n=108).
