Transcatheter aortic valve implantation in nonagenarians: effective and safe.
BACKGROUND
The number of nonagenarians is rising dramatically. These patients often develop severe aortic stenosis for which transcatheter aortic valve implantation (TAVI) is an attractive option. The aim of this study was to analyze the outcome of TAVI performed in a cohort of nonagenarian patients.


METHODS
Between August 2008 and November 2012, 23 consecutive patients in their 90th year of age or older underwent TAVI in our institution after having been assessed by the local heart team. Data concerning baseline characteristics, procedural details and outcome were prospectively entered into a dedicated database. Transthoracic echocardiography and clinical follow-up were performed pre-procedure, at discharge, at 6 and 12 months and then annually post TAVI.


RESULTS
Patients were male in 52% with a mean age of 90.3 ± 2.3 years. Mean logistic EuroSCORE and STS score were 26.6 ± 14.5% and 8.7 ± 2.9%, respectively. Transcatheter heart valve (THV) could be implanted in all but one patient. Mortality at 30 days was 8.7% overall and 4.8% for transfemoral approach. At 30 days the rate of stroke was 4.3%, paravalvular leak grade ≥ 2 was 8.7%, life-threatening bleeding was 13.0% and pacemaker implantation was 13%. Device success was 73.9%. The rate of all-cause mortality increased to 27.3% at one-year follow-up and 42.8% at a median follow-up of 417 days.


CONCLUSIONS
TAVI is safe and effective even in a selected population of nonagenarians. Consequently, these patients should not be refused such a procedure based only on their age. Multi-disciplinary assessment is essential in order to properly select candidates.
