| Description: | Aortic stenosis (AS) describes a condition where the aortic valve is smaller or tighter than it should be. As a result, the valve moves less freely and the heart has to contract (squish) harder to push blood across the valve. Great Ormond Street Hospital provides information on diagnosis, causes and treatment of aortic valve stenosis for both children and parents.We hope you find our website useful and informative and we look forward to working with those of you who require our services. |
