Bioprosthetic leaflet immobility is under-recognised and is highlighted by an article
by Naser et al. [
[1]
] in this edition of Heart, Lung and Circulation. The authors assert in their conclusions that “Immobile leaflet immediately post-bioprosthetic
valve implantation is frequently under-recognised intra-operatively and appears to
be associated with early bioprosthetic dysfunction and worse clinical outcome”. The
valves assessed were predominantly porcine and while the number of cases is small,
there was not much detail on the overall percent incidence of this issue. However,
the presence of early bioprosthetic valve regurgitation and leaflet hypomobility is
something that most cardiac surgeons and cardiac anesthetists are aware of, even if
reported findings are uncommon.Keywords

- PreviewSince the last formal publication reporting on the findings of the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) database on surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) in 2016, transcatheter approaches have become common practice. There has been an increase in use of TAVR following large, randomised control trials that only report on short-term outcomes in a selective cohort. This study aims to report on primary outcome measures and identify complications associated with SAVR and TAVR from a large national database.
