Early haemodynamic valve deterioration after TAVI occurred in 3.1% of patients and was independently associated with lower valve-related long-term clinical efficacy (sHR 0.42; 95% CI 0.32-0.56).

Does early haemodynamic valve deterioration worsen long-term clinical efficacy in patients undergoing TAVI?
Early haemodynamic valve deterioration after TAVI is a strong predictor of adverse long-term clinical and haemodynamic outcomes, including stroke and bioprosthetic valve failure.
Effect estimate: sHR 0.42 (95% CI 0.32-0.56)
BACKGROUND: Early haemodynamic valve deterioration (HVD) was associated with worse clinical outcomes and bioprosthetic durability after transcatheter aortic valve implantation (TAVI) in a single-centre study. AIMS: The aim of this study was to evaluate the incidence, predictors, and prognostic impact of early HVD in a large-scale TAVI population. METHODS: We analysed the data from an international, multicentre registry including consecutive patients from 16 centres undergoing TAVI. Early HVD was defined as an increase of at least 10 mmHg in the mean transaortic gradient on echocardiography performed within the first three months after TAVI, compared with the discharge echocardiography. The primary endpoint was the valve-related long-term clinical efficacy according to the Valve Academic Research Consortium 3. RESULTS: increase 1.15, 95% confidence interval CI: 1.02-1.30), prosthesis size <26 mm (aOR 1.96, 95% CI: 1.43-2.70), valve-in-valve procedure (aOR 2.76, 95% CI: 1.83-4.08), and the absence of anticoagulation at discharge (aOR 1.64, 95% CI: 1.22-2.22) were independent predictors of early HVD. After a median follow-up of 4 years (interquartile range 2-5), early HVD was independently associated with a lower valve-related long-term clinical efficacy (subdistribution hazard ratio sHR 0.42, 95% CI: 0.32-0.56), and a higher risk of stroke (sHR 2.32, 95% CI: 1.51-3.57), stage 2 or 3 (sHR 2.74, 95% CI: 2.10-3.57) or stage 3 bioprosthetic valve dysfunction (sHR 3.53, 95% CI: 2.15-5.79), and bioprosthetic valve failure (sHR 3.04, 95% CI: 2.06-4.52). Consistent findings were observed in a propensity score-matched cohort and in different sensitivity analyses. CONCLUSIONS: Early HVD was observed in 3.1% of patients and was associated with adverse clinical and haemodynamic outcomes after TAVI. These findings validate the clinical relevance of detecting early HVD and the necessity for further research to guide optimal management of these patients.
Trimaille et al. (Tue,) conducted a cohort in Transcatheter aortic valve implantation (TAVI). Early haemodynamic valve deterioration (HVD) vs. No early HVD was evaluated on Valve-related long-term clinical efficacy according to the Valve Academic Research Consortium 3 (sHR 0.42, 95% CI 0.32-0.56). Early haemodynamic valve deterioration after TAVI occurred in 3.1% of patients and was independently associated with lower valve-related long-term clinical efficacy (sHR 0.42; 95% CI 0.32-0.56).
