About

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. Although significant progress has been made in understanding the pathophysiological mechanisms underlying the onset and progression of AS, there is no medical treatment to slow or prevent its progression. The only treatment available is Aortic Valve Replacement (AVR) performed by surgery or by catheterization (TAVI).

Once a diagnosis has been made and the decision to treat these patients has been taken, the procedure (AVR or TAVI) must be performed rapidly given the poor prognosis of the disease without treatment. Studies have shown that on the waiting list, the probability of death and hospitalisation for heart failure increases with time. This delay could also reduce the effectiveness of TAVI, thus affecting the performance of the healthcare system.

In this study, an intervention combining an e-health component (tool intended for patients, families and health professionals in contact with patients), and an organisational component (for TAVI implanting centres) has been designed. The aim of this study is to evaluate the effectiveness of this intervention.
