M mode echocardiography at level of chordae tendinae revealed dilation of left ventricle (LVIDd-5.
Gross features are characterized by mitral valve stenosis due to commissural fusion, leaflet thickening and subvalvular disease with shortened, thickened, and often fused, chordae tendineae.
Intraoperative chordae assessment by artificial erection was performed followed by total mobilization of the urethral plate, and a correction with dorsal plication.
Inclusion criteria were anterior distal shaft hypospadias with good urethral plate and exclusion criteria were association with chordae and history of previous surgery.
The company has established a commercial beachhead in Europe for its technology, which allows for the implantation of artificial chordae tendinae, a technique for the repair of mitral valve prolapse, via a transapical, off-pump procedure," Chung said.
Criteria for success of any hypospadias repair is glanular meatus, single forward directed stream, unimpeded voiding, absence of penile chordae, good cosmesis and no need for secondary procedure.
Sudden death is a major event in severe MR with rupture of chordae tendineae and causes about 25% of deaths of patients on medical treatment.
The chordae tendineae were ensheathed with a layer of endothelium and were composed of dense bundles of collagenfibers, few elasticfibers, fibroblasts, andbloodvessels.
Mitral valve has an orifice with its supporting annulus, leaflets, a variety of tendinous chordae and papillary muscles.
Past medical history was significant for asymptomatic mitral valve prolapse, moderate mitral regurgitation and chordae tendinea rupture diagnosed two years previously.
An adult male with severe eccentric mitral regurgitation caused by posterior leaflet prolapse underwent mitral valve repair by creation of new chordae at the posterior mitral leaflet.
A linear structure was identified extending from the chordae of the anterior mitral valve leaflet to the ventricular septum just below the aortic valve annulus.
