Abstract
Abstract
Background
Mean gradient (MG) elevation can be detected immediately post-procedure or secondarily during follow-up. Comparison between these two parameters and impact on outcomes has not previously been investigated.
Objectives
The study aimed to identify incidence, influence on prognosis and parameters associated with immediate high post-procedural mean transvalvular gradient (PPMG) and delayed mean gradient increase (DMGI), in the FRANCE 2 (French Aortic National CoreValve and Edwards 2) registry.
Methods
The registry includes all consecutive symptomatic patients with severe aortic stenosis. Three groups were analyzed: 1) PPMG <20mmHg without DMGI >10 mmHg (control); 2) PPMG <20mmHg with DMGI >10 mmHg (group 1); 3) PPMG ≥20 mmHg (group 2).
Results
From January 2010 to January 2012, 4201 consecutive patients were prospectively enrolled in the registry. The control group comprised 2078 patients; the group 1, 131 patients; and the group 2, 144 patients. DMGI exceeded 10 mmHg in 5.6%, and was not associated with greater 4-year mortality than in control group (32.6% vs. 40.1%, p=0.27, respectively). PPMG was at least 20 mmHg in 6.1%, and was associated with higher 4-year mortality than in control group (48.7% versus 40.1%, p=0.005, respectively) (Figure 1). Two-thirds of patients with initial PPMG ≥20 mmHg had finally a MG <20 mmHg at 1 year, with mortality similar to controls (39.2% vs. 40.1%, p=0.73).
Conclusions
Patients with PPMG >20 mmHg 1 year post-TAVI had higher 4-year mortality than the general population of the registry, unlike patients with MG normalization at 1 year.
