Case ReportsSevere aortic regurgitation after implantation of a sutureless valve prosthesis using an automatic knot fastener device.
We report the case of severe aortic regurgitation 8 months after implantation of a 25-mm sutureless pericardial aortic valve prosthesis. On echocardiography, the regurgitation was suspected to be paravalvular. The sutureless prosthesis had been implanted using an automatic knot fastener device, which renders the suture tails less pliable because of the metal clip that is crimped around the suture. ⋯ The leaflet perforation was in alignment with one of the knots produced by the automatic knot fastener. Obviously, the leaflet had hit the knot repeatedly which had caused the perforation. We conclude that knots produced by an automatic fastener device have the potential to cause leaflet perforation.

Observational StudyTransapical transcatheter mitral valve-in-valve implantation versus minimally invasive surgery for failed mitral bioprostheses.
The aim of this study was to compare early outcomes and survival of patients undergoing minimally invasive mitral valve replacement through a right anterior minithoracotomy (MIMVR) versus patients undergoing transcatheter transapical mitral valve-in-valve (M-VIV) implantation for a failed mitral bioprostheses. ⋯ In selected patients, M-VIV can be performed safely with results comparable with those of surgical therapy.
