Aortic valve replacement is a cardiac surgery procedure whereby a failing aortic valve is replaced with an artificial heart valve. The aortic valve may need to be replaced because of aortic regurgitation (back flow), or if the valve is narrowed by stenosis .
Aortic valvuloplasty relies on placing a catheter with a balloon at the tip in the aortic valve, which is then inflated to widen the narrowed valve. [1] In order to reach the aortic valve, a blood vessel is punctured to introduce the catheter and advance it into the aortic valve. The most common site of entry is the femoral artery in the groin ...
The transfemoral approach requires the catheter and valve to be inserted via the femoral artery. Similar to coronary artery stenting procedures, this is accessed via a small incision in the groin, through which the delivery system is slowly fed along the artery to the correct position at the aortic valve.
Heyde's syndrome; A stenotic aortic valve: Specialty: Cardiology, general surgery, Hematology: Symptoms: Aortic valve stenosis symptoms: Chest pain (angina) or tightness Shortness of breath, especially during exertion or when lying down Fatigue or weakness Irregular heartbeat or heart palpitations Dizziness or fainting episodes Gastrointestinal bleeding symptoms: Occult (hidden) or overt ...
Diagram of the human heart. Several adaptations of the Ross procedure have evolved, but the principle is essentially the same; to replace a diseased aortic valve with the person's own pulmonary valve (autograft), and replace the person's own pulmonary valve with a pulmonary valve from a cadaver (homograft) or a stentless xenograft.
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.
