| | Aortic valve stenosis - Wikipedia, the free encyclopedia |
 | | Aortic valve stenosis (AS) is a heart condition caused by the incomplete opening of the aortic valve. | | | The Gorlin equation states that the aortic valve area is equal to the flow through the aortic valve during ventricular systole divided by the systolic pressure gradient across the valve times a constant. | | | The Gorlin equation is related to flow across the valve. |

| | Aortic Valve Stenosis |
| | This type of valve surgery may be used in people younger than 25 who stand to benefit the most from this difficult surgery; the pulmonic valve is more durable, grows with the person, and has a lower risk of infection. | | | The risk of surgery is higher than average for people who have severe aortic valve stenosis, failure of the left ventricle, and a low ejection fraction. | | | if you have symptoms of aortic valve stenosis, unless you have other conditions that make surgery too risky. |

| | MedlinePlus Medical Encyclopedia: Aortic stenosis |
| | Aortic stenosis is the narrowing or obstruction of the heart's aortic valve, which prevents it from opening properly and blocks the flow of blood from the left ventricle to the aorta. | | | Surgical repair or replacement of the valve is the preferred treatment for symptomatic aortic stenosis. | | | Notify the health care provider or dentist about any history of heart valve disease before treatment for any condition. |

| | Aortic Valve Stenosis and Insufficiency |
| | Stenosis and insufficiency can change as you age, whether or not you've had surgery or catheterization. | | | The aortic valve lets blood flow from the heart's left ventricle into the aorta. | | | Your aortic valve can be surgically replaced in three ways: |

| | Other symptoms associated with aortic stenosis are angina (chest pain) and fainting upon exertion (syncope). | | | Further studies may include an electrocardiogram (EKG), chest X-ray, echocardiogram (ultrasound study of the heart), and cardiac catheterization. | | | Balloon valvuloplasty is usually reserved for those people who are poor candidates for surgery or as an intermediate procedure to stabilize high-risk patients prior to surgery. |

| | Gale Encyclopedia of Medicine: Aortic valve stenosis |
| | The valve can be opened without surgery by using a balloon catheter, but this is often a temporary solution. | | | When the valve narrows, as it does with stenosis, blood flow is impeded. | | | In severe stenosis, heart valve replacement is recommended, most often involving open-heart surgery. |

| | Congenital Aortic Valve Stenosis |
| | The aortic valve opens to allow blood to flow from the left ventricle of the heart to the aorta, and then to the body. | | | “Congenital” aortic valve stenosis means the condition is present at birth. | | | Unless it is severe, the condition is often not detected until later in life. |

| | I had a CMV in 1971 and MVR with St. Jude mechanical valve in 1986, since then I’ve been taking blood thinner drugs and diuretics. | | | I have not heard of this surgery and would not rush to any new surgery that is not proven by time. | | | Sorry to hear about your valve surgeries and recurrent problems. |

| | Rarely, these valve problems may occur in infancy, such as poor blood flow, anemia, and heart failure. | | | Severe blockage may cause chest pain or feeling a loss of consciousness with activity. | | | If the defect causes life-threatening heart failure in infancy, immediate surgery to repair the valve will be necessary. |

| | Aortic Valve Stenosis -- Overview |
| | When the heart rests between beats, the aortic valve closes to keep blood from flowing backward into the heart. | | | When the heart pumps, the aortic valve opens to allow oxygen-rich blood to flow from the left ventricle into the aorta. | | | Blood then flows through the aorta into a larger network of arteries branching out through the body. |
