Abstract
Introduction: We describe the largest South African
transcatheter aortic valve implantation (TAVI) outcome
report of a single team in the Western Cape, over a
7-year period from 2009 - 2016.
Methods: All patients who received TAVI at Mediclinic
Vergelegen and Mediclinic Panorama were prospectively
entered into a database. A total of 244 implants (61
CoreValve and 183 Edwards valves) were performed.
Results: Patients were high risk with a mean STS score
of 7.89 (standard deviation (SD) 5.7) and mean logistic
EuroSCORE of 26.5 (SD 12.5). There was a trend toward
lower risk over time. Procedures were initially performed
mainly via a transapical approach, but this
changed to mostly transfemoral with the introduction
of smaller delivery systems. Procedural success rate
was 91.8% for CoreValve and 88.5% for Edwards cases.
Mean length of hospital stay following TAVI was 9 days
initially, but this declined to 4 days for the latter part of
our experience. One year mortality was 19% and one
year stroke rate was 10%.
Conclusion: Despite the limitations of a study of this
nature, our group could document outcomes similar to
international studies, with improvements over time and
illustrating successful cooperation between different
hospitals to expand exposure and experience in a
resource-constrained environment.
