The development of this heart valve substitute, its techniqueof implantation and the results observed in the first group of 50 patientshave had us to review the initial experience. The surgical protocolincluded an accurate mitral valve complex analysis, adequate valve sizeselection, attachment of the papillary muscle to the new chordal origin andapproximation of the stentless mitral to the patient's annulus. There wasone hospital death (2%), not related to the valve or to the technique andfour reoperations: two due to endocarditis, one because of a perivalvularleak and one due to a mismatched stentless valve. The late mortality (4%)was not valve- related. The follow-up has shown excellent valve performancewith improved left ventricular function in the great majority of thepatients. Based on the current analysis, it can be stated thatreproducibility of the surgical technique and the excellence of theclinical follow-up may contribute favorably to a better quality of life andlonger valve durability in patients requiring mitral heart valvereplacement. © Springer-Verlag 1995 European Journal of Cardio-Thoracic Surgery Elsevier Science B.V. 9/2(1995-02), 69-73 1010-7940 9:2<69 1995 9 ejcts https://doi.org/10.1016/S1010-7940(05)80020-X text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1016/S1010-7940(05)80020-X text/html Onlinezugriff via DOI NATIONALLICENCE 773 0- European Journal of Cardio-Thoracic Surgery Elsevier Science B.V 9/2(1995-02), 69-73 1010-7940 9:2<69 1995 9 ejcts Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
