The ideal conduit for reconstruction of the right ventricular outflow tract in pediatric patients remains a topic discussion. We present technique construction handmade tricuspid valved polytetrafluoroethylene use all ages requiring at time congenital cardiac surgery. This provides an economically advantageous and readily available option globally when compared with homograft, without sacrifici...

A 74-year old patient developed severe aortic valve regurgitation 11 years following root replacement using a stentless Shelhigh tube-graft. Computed tomography scan showed a heavily calcified aortic conduit (Fig. 1), although the company claims that detoxification process eliminates residual glutaraldehyde and ensures less calcification in the long term. The patient underwent successful transa...

The in vivo evaluation of prosthetic device performance is often difficult, if not impossible. In particular, in order to deal with potential problems such as thrombosis, haemolysis, etc., which could arise when a patient undergoes heart valve replacement, a thorough understanding of the blood flow dynamics inside the devices interacting with natural or composite tissues is required. Numerical ...
