Qualitätsparameter für den Aortenklappenersatz

Zusammenfassung

Die Vor- und Nachteile von mechanischen und biologischen Herzklappenprothesen ebenso wie die Komplikationen im Verlaufe von Langzeitstudien sind verantwortlich für die Qualität eines Aortenklappenersatzes. Die anatomischen Gegebenheiten wie enge Aortenwurzel, gleichzeitiges Vorhandensein einer koronaren Herzerkrankung oder reduzierte linksventrikuläre Funktion beeinträchtigen die relativ guten Operationsergebnisse und erfordern eine chirurgische Intervention oder die Verwendung von gerüstfreien Klappenprothesen.

Summary

Advantages and disadvantages of mechanical or biological heart valve prostheses in combination with complications during long-term follow-up are responsible for the quality of aortic valve replacement. Anatomical conditions like narrow aortic root, concomitant coronary artery disease or reduced left ventricular function impair the quite good surgical results necessitating surgical intervention or the use of stentless valve implants.
