What is the difference between stenosis and insufficiency?
A narrowed or stenotic valve requires the heart to pump harder, which can strain the heart and reduce blood flow to the body. A regurgitant (incompetent, insufficient, or leaky) valve does not close completely, letting blood move backward through the valve.
Can you have both aortic stenosis and regurgitation?
Mixed aortic valve disease (MAVD) refers to the coexistence of aortic stenosis (AS) and aortic regurgitation (AR). Despite the relatively high prevalence of MAVD, there are very few data on the outcome and management of this entity.
What symptoms indicate worsening of aortic stenosis?
- Abnormal heart sound (heart murmur) heard through a stethoscope.
- Chest pain (angina) or tightness with activity.
- Feeling faint or dizzy or fainting with activity.
- Shortness of breath, especially when you have been active.
- Fatigue, especially during times of increased activity.
What is the most common cause of aortic insufficiency?
The most common cause of chronic aortic regurgitation used to be rheumatic heart disease, but presently it is most commonly caused by bacterial endocarditis. In developed countries, it is caused by dilation of the ascending aorta (eg, aortic root disease, aortoannular ectasia).
Is it safe to exercise with aortic stenosis?
If you have mild stenosis, you will not need to restrict your level or type of physical exercise. But if you have severe stenosis, you should avoid strenuous activities such as weight lifting or running.
What is the life expectancy for severe aortic stenosis?
Life expectancy is 1 or 2 years for patients with heart failure phenomena, 2 or 3 years in those with syncope and 4 or 5 years, in patients with angina pectoris. Among patients with severe aortic stenosis, medically treated, 50% die in 2 years, half of them by sudden death.
What are the signs of aortic stenosis?
Signs and symptoms of aortic stenosis are due to heart failure and include chest pain, shortness of breath, and lightheadedness or fainting.
Does mild aortic stenosis need surgery?
Mild to moderate aortic stenosis typically does not require surgery. But, surgery is necessary for severe cases of aortic stenosis. If left untreated, severe aortic stenosis can result in heart failure.
What is the prognosis for aortic valve stenosis?
The prognosis for aortic valve stenosis depends on the severity of the disease. With surgical repair, the disease is curable. Patients suffering mild stenosis can usually lead a normal life; a minority of the patients progress to severe disease. Anyone with moderate stenosis should avoid vigorous physical activity.
