Stenosis of the aortic valve disease
There are two processes protypical the aortic valve stenosis - aortic stenosis, where the distributor is not entirely open to impede blood circulation in the hearts and aortic stenosis belching, where aortic stenosis and the valve is incompetent Passivement blood flowing again in the hearts in the wrong direction. These two conditions often coexist.
* Aortic stenosis of the common causes include rheumatic fever, calcification and degenerative diseases such as innate bicuspid aortic valve stenosis.
* Common causes of aortic stenosis belching are part of the aorta dilation previous rheumatic fever, infections, ie infective endocarditis, aortic stenosis myxomatous degeneration of the valve and Marfan syndrome.
Bicuspid aortic valve stenosis
Mistakes or elsewhere often diagnosed at a later related.
Patients with this anomaly are at increased risk for a variety of cardiovascular diseases and complications that require monitoring their valvular aortic stenosis and diseases. During echocardiography is usually the first method of diagnosis, MRI can be a valuable complement to a broad examination of the aortic stenosis and aortic valve.
Most often innate malformation of the heart is the bicuspid aortic valve stenosis. In this state, instead of three cusps, the aortic valve stenosis has two cusps. This condition is often diagnosed later in life, if the person develops a symptomatic aortic stenosis. Of aortic stenosis occurs in this state, usually in patients in their 40 or 50, on average 10 years earlier than in humans can occur with valves congenitally aortic stenosis.
Aortic Valve Replacement
Aortic valve stenosis exchange means that a patient’s aortic valve stenosis is replaced by another valve. The aortic valve stenosis may be affected by a number of diseases aortic stenosis and require replacement valve. The valve can be turned into leaks (regurgitant or insufficient) connect or partially closed (stenotic). Stenosis aortic valve replacement currently requires open heart surgery. The research is done now to develop that valves can be implanted with a catheter without open heart surgery. There are two main types of artificial heart valve, valves and mechanical fittings tissues. Tissue heart valves are usually animal tissue, heart valve or animal tissues pericardial tissue of animal origin. The fabric is treated to prevent rejection and prevent calcification.
There are alternatives to animal tissue valves. In some cases, aortic valve stenosis human can be implemented. These are homografts. Homograft valves are given by the patient and can be harvested after the patient expires. The shelf life of homograft valves is probably the same for pig tissue valves. Another procedure for aortic stenosis replacement valve is the process Ross (after Donald Ross) or pulmonary autograft. The procedure includes Ross, the operation, which aortic valve stenosis is deleted and replaced by the patient’s own pulmonary valve. A pulmonary homograft (a pulmonary valve, from a corpse) or a valvular prosthesis is then be used, patients who replace their own pulmonary valve.
