TAVIGER : Intérêt d’une expertise coordonnée gériatrique et cardiologique dans le bilan d’éligibilité des patients âgés à un remplacement valvulaire aortique par voie percutanée

Background

Transcatheter aortic valve implantation (TAVI) is the gold standard treatment for aortic stenosis in the elderly. Pre-identification of patients likely to benefit from this procedure remains crucial. A standardised geriatric assessment is used to identify the major geriatric syndromes likely to influence postoperative outcomes.

Objective

To identify factors associated with lack of TAVI management and to compare one-year survival in TAVI vs. non-TAVI patients.

Methods

Retrospective study, between 2016 and 2020, at the Arras hospital. Patients aged 70 years and older with symptomatic severe aortic stenosis who had undergone geriatric assessment were included.

Results

One hundred and ninety-two (192) patients, mean age 82.3 years. The 1-year mortality rate was 18% in the TAVI group and 44% in the non-TAVI group (p < 0.001).

Parameters associated with no TAVI were Euroscore (ESL) 1 (19.6 ± 10.9 vs. 23.2 ± 13.5, p = 0.020), malnutrition (14% vs. 35%, p = 0.004), walking speed < 0.8 m/s (39% vs. 75%, p = 0.001), Activities of Daily Life (ADL) score (5.4 ± 1 vs. 4.2 ± 1. 6, p < 0. 001) and Instrumental Activities of Daily Life (IADL) score (2.6 ± 1.2 vs. 1.8 ± 1.4, p = 0.002), Mini Geriatric Depression Scale (mini GDS) ≥ 1 (16% vs. 38%, p = 0.045), Mini Mental State Examination (MMSE) score (25.1 ± 3.5 vs. 21.6 ± 4.3 < 0.001).

Conclusions

Geriatric syndromes are important determinants of TAVI candidacy. Cardiological surgical risk scores are not effective in discriminating between patients. Coordinated assessment may optimise selection. Therefore, geriatric assessment should be systematically performed as part of the pre-TAVI evaluation.
