Living artificial heart valve alternatives: a review.
Conventional replacement therapies for heart valve disease are associated with significant drawbacks. The field of tissue engineering has emerged as an exciting alternative in the search for improved heart valve replacement structures. One of the principles behind this concept is the transplantation of living elements, embedded in a suitable scaffold material, to the diseased site where the str...
متن کاملArtificial Intelligence in Mitral Valve Analysis
BACKGROUND Echocardiographic analysis of mitral valve (MV) has become essential for diagnosis and management of patients with MV disease. Currently, the various software used for MV analysis require manual input and are prone to interobserver variability in the measurements. AIM The aim of this study is to determine the interobserver variability in an automated software that uses artificial i...
متن کاملMitral Valve Subvalvular Apparatus Repair with Artificial Neochords Application
Degenerative mitral valve (МV) disease is a common disorder affecting around 2% of the population (Enriquez-Sarano M et al., 2009). The most common ending in patients with degenerative valve disease is leaflet rolapsed due to elongation or rupture of the chordal apparatus, resulting in varying degrees of МV regurgitation due to leaflet malcoaptation during ventricular contraction. The emphasis ...
متن کاملArtificial chordae for pediatric mitral and tricuspid valve repair.
OBJECTIVE To evaluate pediatric atrioventricular valve repair with artificial chordae. METHODS Between February 2001 and January 2006, artificial chords were used in 21 children with severe mitral or tricuspid valve regurgitation. Patients with AVSD were excluded. Median age was 84 (1-194) months. Five patients had isolated tricuspid valve anomalies, 16 had mitral valve anomalies (associated ...
متن کاملTurbine Valve Control Based on Artificial Neural Networks
Conventional schemes of fast valving generate a fixed valve stroke sequence for the control of turbine valves under transient conditions. A simple fixed valve control sequence cannot give optimum result for different fault conditions and loading levels, due to its poor adaptability. This paper presents an artificial-neuralnetwork (ANN) based controller to govern the operation of the turbine con...
