A total of 149 patients (64%) were treated with a self-expandable valve and 80 (34.7%) with a balloon-expandable valve. (ox.ac.uk)
Self-expanding Medtronic Evolut R valves were used in 84% of TS procedures, while balloon-expandable Edwards SAPIEN valves were used in all TA procedures. (biomedcentral.com)

Because of the unicuspid form of the valve the repair concept will be similar to that of the regurgitant unicuspid valve. (wikipedia.org)

Sometimes, aortic valves that are leaking (regurgitant) can be repaired. (ctsurgerypatients.org)
Any heart valve can become stenotic or insufficient (also termed regurgitant or incompetent), causing hemodynamic changes long before symptoms. (msdmanuals.com)

Women with heart conditions who become pregnant may be at some risk depending on the severity and type of cardiovascular disease. (babygest.com)

The best option for treating valve disease is to repair the damaged valve. (hoag.org)
For some patients with aortic valve disease, conventional surgery is not an option. (hoag.org)
Repairing versus replacing the aortic valve is determined by a number of factors, such as the anatomy of the valve and the degree of its disease. (hoag.org)
Nancy & Bill Thompson Heart Valve Center is one of a handful of clinics nationwide dedicated to state-of-the-art screening, diagnosis, and treatment of valvular heart disease. (hoag.org)
According to the American Heart Association, about 5 million people a year are diagnosed with heart valve disease. (dotmed.com)
This type of anemia includes sickle cell anemia, thrombotic thrombocytopenic purpura (TTP), hemolytic uremic syndrome, aortic valve prosthesis, disseminated intravascular coagulation (DIC), cold agglutinin disease, and paroxysmal cold hemoglobinuria (PCH). (medscape.com)
While postoperative AR was seen in one patient with Takayasu's arteritis (n= 1, 4.16%), it was not observed in the patients with Marfan syndrome or bicuspid aortic valve disease. (kosuyoluheartjournal.com)
Acquired aortic valve disease occurs because your valve simply wears out over time, and usually happens as you age. (ctsurgerypatients.org)
Your doctor can usually diagnose aortic valve disease based on your medical history, risk factors, a physical exam, and with results from tests and procedures. (ctsurgerypatients.org)
There is no one test that can diagnose aortic valve disease, so your doctor may recommend one or more of the following: electrocardiogram (EKG), echocardiogram (echo), chest x-ray, blood tests, and coronary angiography. (ctsurgerypatients.org)
Currently, NO MEDICATION can cure aortic valve disease, so it is most commonly treated with surgery. (ctsurgerypatients.org)
Let's talk about these "spare parts" available to us for the treatment of heart valve disease. (heartsurgeryinfo.com)
Bacterial genetic characteristics also influence disease type and severity. (biomedcentral.com)
This usually depends on the type of heart disease and its severity, so each case should be evaluated by a cardiologist. (babygest.com)
