Pulmonary Hypertension Clinical Trial
Official title:
Prognostic Impact of the Evolution of Pulmonary Arterial Hypertension 3 Months After Transcatheter Aortic Valve Implantation
Aortic stenosis (AS) is the most frequent valvulopathy in Western countries. The prevalence
of AS is constantly increasing due to the aging of the population. Several studies have shown
that pulmonary arterial hypertension (PAH) was common in AS patients referred for TAVI and
that it was an independent predictor of mortality after TAVI.
Currently, there is no data in the literature regarding the evolution and prognosis value of
PAH measured using right heart catheterization (reference method). PAH could either regress
after TAVI or continue to progress despite the treatment of valvulopathy, resulting in a
refractory right heart failure that can lead to death.
The hypothesis of this study is that patients with PAH before TAVI procedure and at the
3-month follow-up visit (PAH persistence) have an increased risk of cardiovascular mortality
compared to patients with no PAH at 3 months or having a significant reduction of their PAH
(PAH regression).
The aim of the study is to evaluate the prognostic impact of the evolution of PAH after TAVI
in 424 patients using right heart catheterization.
