State of the Art - Aortic stenosis: from epidemiology to treatment

ESC Congress Report

Diseases of the Aorta

The highlight session focus on advances in aortic stenosis  included  five presentations which cover all aspects from aetiology to surgical management. 

Bicuspid aortic valve is one of the most common causes of aortic stenosis.  Amelia Carro et al analysed the results of echo familial screening in bicuspid aortic valve.  The prevalence of bicuspid valve in the first degree relatives was 7% and the families with another bicuspid case were 19%. A surprising result of the study is that in 30% of cases, the valve phenotype was different within the family. This data may imply significant information for understanding the genetic bases of this disease.

In another communication Lin et al showed that the LV remodelling of AS in patients with different body mass index was similar from underweight to obese patients. A multicentre Japanese study proposes a new echocardiographic parameter to improve the prognosis value of this technique respect to events in the follow-up. This parameter can improve the risk stratification of patients with severe AS. 

Sato et al show the advantages to quantify the AVA by 3D-echo compare with classical Doppler approach. 3D method was a better predictor of complications particularly in presence of upper septal hypertrophy. 
Finally, the Group of Leiden compared the echocardiographic results of a series of 80 patients treated with transcatheter aortic valve implantation (TAVR) vs

suturless valve prostheses implanted by surgery. TAVR showed a better haemodynamic results in terms of valvular area, gradients and lower mismatch than stenless prosthesis. However, the mid-term survival at 2 years was comparable in both groups. 

The session finished with a state of the art remaking the impact of these excellent presentations in clinical practice.
