INTRODUCTION Transcatheter aortic valve implantation is the option of choice for high surgical risk patients suffering from symptomatic aortic stenosis. We aimed to evaluate the influence of baseline global longitudinal strain on left ventricular mass regression after the procedure. METHODS We enrolled 23 patients with pure symptomatic severe aortic stenosis who underwent CoreValve prosthesis...

Dehiscence of the valve is a serious complication of prosthetic heart valve replacement. It has grave consequences unless promptly diagnosed and corrected by surgery. We report the case of a symptomless patient with near-complete detachment of the aortic prosthesis, diagnosed by radiography and two-dimensional echocardiography. This was confirmed at surgery and the dehisced prosthetic valve was...

INTRODUCTION Percutaneous transcatheter aortic valve implantation (TAVI) has become an established therapy for inoperable and high-surgical-risk patients with severe aortic stenosis. Although TAVI in patients with degenerated surgical aortic bioprostheses (i.e. valve-in-valve TAVI) is increasingly reported in Western studies, such data is lacking in Asian patients. We describe the initial exper...

OBJECTIVE The aim of the current study was to evaluate the early experience of the application of transcatheter aortic valve implantation with the balloon-expandable system in China. The transcatheter aortic valve implantation technology has been widely used for patients with inoperable severe aortic stenosis in the developed world. The application of transcatheter aortic valve implantation is ...

OBJECTIVES We present our single-centre experience with the direct flow medical (DFM) trans-catheter aortic valve implantation (TAVI) prosthesis addressing the impact of learning curve upon outcomes. BACKGROUND The DFM has been recently introduced for TAVI. The prosthesis presents original design and implantation features. METHODS Patients were divided into three groups according to the chr...

BACKGROUND The CarboMedics valve is a relatively new, low-profile, bileaflet, mechanical prosthesis. The results of a prospective follow-up study after valve replacement with this prosthesis in a university hospital are presented. METHODS We implanted 640 CarboMedics prostheses in 583 patients in the aortic (n = 359), mitral (n = 167), or aortic and mitral positions (double valve replacement;...

BackgroundThe durability of bioprostheses in the pulmonary position patients with congenital heart disease remains suboptimal. The new INSPIRIS Resilia aortic valve is characterized by a pericardial tissue that could improve hemodynamic performance and durability. We report initial experience this children young patients.MethodsA retrospective study was performed. Demographic, clinical, echocar...

SEE PAGE 805 T he occurrence of conduction disturbances and the need for permanent pacemaker implantation remain a significant issue associated with transcatheter aortic valve replacement (TAVR) (1). Indeed, the contiguity of the conduction system to the aortic annulus (landing zone of transcatheter valve prostheses) makes this procedure likely to develop this complication (2). To date, several...

In order to obtain mechanical specifications for the design of an artificial leaflet valve prosthesis, a geometrically non-linear numerical model is developed of a closed Hancock leaflet valve prosthesis. In this model, the fibre reinforcement of the leaflet and the viscoelastic properties of frame and leaflets are incorporated. The calculations are primarily restricted to 1/6 part of the valve...

Transcatheter aortic valve implantation (TAVI) is a recently developed surgical technique to treat symptomatic aortic valve stenosis in elderly and high-risk patients (Eltchaninoff et al., 2008; Ferrari & von Segesser, 2010). Compared to the standard aortic valve replacement surgery, the TAVI limits the surgical access to either a small minithoracotomy (transapical TAVI) or femoral approach (tr...
