Distal Aortic Stenosis
Aortic stenosis...: Is narrowing or restriction of the aortic valve leaflets. When it occurs at old age it is usually senile calcific aortic stenosis and occurs on previously normal valves. Younger patients with stenosis tend to abnormal leaflets (2 vs 3). Mechanical stress may lead to valve thickening and fusion of the leaflets, which limits flow across the valve. With time, calcium may buildup on the valve as well. ...Read more
The abnormal narrowing of the aortic valve. Progressive narrowing of the aortic valve means the heart must work harder to contract and "squeeze" the blood through a smaller and smaller outflow orifice. This will eventually cause symptoms such as chest pain, dyspnea, ...Read more
Surgery vs Meds: Initially aortic stenosis (as) is treated with medications, but when the heart begins failing due to it as well as a few other parameters, it is time to think about surgical valve replacement. This can be done either as a traditional open heart operation or in some cases now percutaneously without having an incision. ...Read more
Aortic stenosis: Aortic stenosis is most commonly caused by age-related progressive calcification of a normal (three-leafed) aortic valve (>50% of cases). Other causes include calcification of a congenital bicuspid aortic valve (30-40% of cases) and acute rheumatic fever (less than 10% of cases). Diabetes, hypertension and hyperlipidemia may speed up the age-related calcification and degeneration of aortic valves. ...Read more
May start from birth: Aortic valve problems may start from birth if the aortic valve was abnormal due to a birth defect. As one ages, there can be progressive wear and tear of a bicuspid valve present since birth. There can also be wear and tear of a previously normal aortic valve in the elderly. Rheumatic fever can also cause scarring of the aortic valve in a child or adult. ...Read more
Echo: An echocardiogram (often called "echo") is a graphic outline of the heart's movement. High-frequency sound waves, called ultrasound, provide pictures of the heart's valves and chambers. This allows the technician, to evaluate the pumping action of the heart. Echo is often combined with doppler ultrasound and color doppler to evaluate blood flow across the heart valves and provides the diagnosis. ...Read more
Aortic stenosis: "Current or history of congenital anomalies of heart and great vessels (746), except for corrected patent ductus arteriosus, are disqualifying." See: http://usmilitary. About. Com/od/joiningthemilitary/a/heart. Htm ...Read more
Valve disease: Classic aortic stenosis is obstruction to blood flow at the aortic valve. The aortic valve connects the heart (left ventricle) to the aorta, which carries blood to the body. A normal aortic valve has three separate leaflets. In typical aortic stenosis in children, there is partial or complete fusion between at least two of the leaflets of the valve, which restricts opening of the valve. ...Read more
It will vary: Aortic stenosis means that the valve that allows blood to go from your heart to the rest of your body is narrowed. How this affects the rest of your body will depend on how narrow it is; if it's severely narrowed it affect blood supply to the rest of the body and coronaries but more importantly it will make your heart work very hard to pump blood out and this may produce long term damage. ...Read more
Aortic Stenosis: Aortic stenosis is the abnormal narrowing of the aortic valve. As the aortic valve develops progressive narrowing, the heart must work harder to contract and "squeeze" the blood through a smaller and smaller outflow orifice. This will eventually cause symptoms such as chest pain, dyspnea, or loss of consciousness. Severe aortic stenosis requires valve replacement. ...Read more
Echocardiogram: Physical exam can be helpful, but echocardiography (cardiac ultrasound) is generally the diagnostic study of choice. Using echo, you can examine the morphology and movement of the valve leaflets, and measuring blood flow velocities, you can estimate pressure gradients to assess severity of obstruction. Cath can sometimes be helpful in assessment and may allow intervention in some cases. ...Read more
Variable: It can vary anywhere from mild to critical. What did your friend's doctor say? ...Read more
Calcium: This operation is rarely used but is done when the ascending aorta is too calcified to operate on. ...Read more
The heart must push harder which is a strain and causes "muscle bound" left ventricular hypertrophy and later heart failure.
The muscle needs more oxygen to pump and coronary flow is interfered with causing angina or heart attack in some.
Low forward flow can lead to fainting syncope.
It is related to degree if stenosis- narrowing of this door!
think of it as a door which does not open fully. ...Read more
No: There are bicuspid aortic valves that have a familial propensity, and those can become stenotic over time. That is one circumstance. ...Read more
Several: The most common symptom is chest pain with effort or in more advanced cases where the stenosis has been severe for many years, decreased exercise tolerance, shortness of breath, light headedness and palpitations among others. Check with your doctor, the diagnosis is usually straight forward. ...Read more
Somewhat: But not uncommon. Discuss causes and treatment plan with your cardiologist. ...Read more
Aortic stenosis: It might progress when you grow, but it depends on the type. ...Read more
No: Only god knows the answer to that question. There are several factors, however, that suggest that an individual may be at increased risk for serious complications. These should be discussed with a cardiologist. There are procedures that can be performed to help improve the aortic valve function. ...Read more
Depends: Asymptomatic pts even with severe as have a good prognosis. 1 percent per yr death rates. With symptoms rates much worse. 25 percent 1 yr and 50 percent 2 yr mortality. 50 percent of these deaths are sudden. When pts have angina, pts usually have their event around 5 yrs from onset of symtoms, 3 yrs for syncope (fainting) and 1-2 yrs heart failure. ...Read more
No: Only if you were born with a bicuspid aortic valve. You should also inquire about your thoracic aortic root size as that is commonly involved as well and becomes aneurysmal. ...Read more
