Accessory aortic-valve tissue as a cause of severe aortic regurgitation: intra-operative finding

Figure 1: Transesophageal echocardiogram showed a dysplastic tricuspid aortic valve (AV) with asymmetrical annular dilation (a) and a severe eccentric aortic regurgitation. The jet was directed posteriorly into the left ventricular outflow tract (anterior mitral leaflet), due to an extreme traction of the non-coronary (NC) cusp and a pseudo-prolapse of the right coronary (RC) cusp generating a large coaptation gap in diastole (b). The basal short axis view (a) shows a thin fibrotic tissue attached to the middle free edge of the NC simulating a double contour of RC (*). On long axis view frame-by-frame (c-e) two filamentous mobile tissues are evident on the aortic surface of the NC and RC cusps (arrows).

24 Percutaneous mitral valve repair with the mitraclip device: a tertiary cardiac UK experience

IntroductionPercutaneous mitral valve repair using the transcatheter Mitraclip device is a novel therapy for patients with severe mitral regurgitation (MR) who are too high risk for conventional surgery. We report...
