Introduction
Transcatheter aortic valve implantation (TAVI) has grown to be an alternative treatment for severe symptomatic aortic valve stenosis (AS) in elderly patients. Although TAVI is a less invasive surgery than surgical aortic valve replacement, some patients may require prolonged hospitalization.

Aim
To find the determinants of prolonged hospitalization in patients who underwent trans-femoral TAVI.

Material and methods
A total of 94 AS patients who underwent trans-femoral TAVI were included as the final study population, and divided into the conventional hospitalization group (≤ 21 days) (n = 74) and prolonged hospitalization group (> 21 days) (n = 20). We compared clinical characteristics between the two groups, and multivariate logistic regression analysis was performed to find the determinants of prolonged hospitalization.

Results
In multivariate logistic regression analysis, moderate or severe mitral regurgitation (OR = 4.49, 95% CI: 1.16–17.47, p = 0.03), taking statins or angiotensin converting enzyme (ACE) inhibitors/angiotensin II receptor blockers (ARB) on admission (statins: OR = 0.13, 95% CI: 0.02–0.71, p = 0.02, ACE inhibitors/ARB: OR = 0.25, 95% CI: 0.06–0.96, p = 0.04), estimated glomerular filtration rate (eGFR) (per 15 ml/min/1.73 m2 incremental) (OR = 0.49, 95% CI: 0.26–0.90, p = 0.02) and current chopsticks user (OR = 0.05, 95% CI: 0.01–0.41, p < 0.01) were significantly associated with prolonged hospitalization.

Conclusions
Moderate or severe mitral regurgitation was significantly associated with prolonged hospitalization, while current chopsticks user, eGFR (per 15 ml/min/1.73 m2 incremental), taking ACE inhibitors/ARB or statins before the procedure were inversely associated with prolonged hospitalization in patients who underwent trans-femoral TAVI.
