Abstract
Background:
Transcatheter aortic valve implantation (TAVI) is used for patients with
severe aortic stenosis who are at high risk for surgery. Since these patients are elderly and have
comorbidities, their management is of great importance.
Objectives:
This retrospective study compares two anesthesia techniques during TAVI: sedation (ketamine
and propofol) and general anesthesia.
Methods:
Patients with severe aortic stenosis undergoing TAVI during 2021 in our hospital were
retrospectively screened. Demographic data, comorbidities, anesthesia management, complications,
and mortality of the patients were obtained from the records.
Results:
There were 137 patients treated with TAVI; 74 (54%) patients had sedation and 63 (46%)
had general anesthesia. When the anesthesia management was evaluated, no significant difference in
mortality was observed between the patients who received general anesthesia and sedation. After
univariate and multivariate logistic regression analyses were performed to investigate factors having
an impact on mortality, anemia (only in univariate analysis) in the whole study population was a statistically
significant risk factor for mortality in patients undergoing TAVI (p<0.014).
Conclusion:
There was no significant difference in mortality in terms of anesthesia management.
Anemia was a risk factor for mortality (only in univariate analysis) in the whole study population.
We concluded that conscious sedation with ketamine and propofol is effective and safe for TAVI
procedures compared to general anesthesia.
