We did not perform acute coronary syndrome, coronary elevation myocardial infarction, whereas angioplasty because the obstruction embolism should be kept in mind in the rest present with non-ST elevation was in the distal portion of the vessel those with prosthetic valves even in the myocardial infarction [8]. (who.int)
There also may be a thrombotic event or heavily calcified valve within the sinus of Valsalva causing obstruction. (medscape.com)

Mitral valve evaluation: mitral valve prolapse is one of the most common indications for 3D-TEE (Figure 4) (2,3), but it also can be useful for mitral stenosis evaluation, especially in cases of poor transthoracic echocardiographic window (4). (escardio.org)

3D transesophageal echocardiography (3D-TEE) has rapidly become the gold standard in the evaluation of every patient with a valve disease. (escardio.org)
In the second - and more common - mitral valve disease type, the valve becomes leaky (regurgitant). (adventisthealth.org)

The aortic valve normally has three cusps or leaflets, although in 1-2% of the population it is found to congenitally have two leaflets. (wikipedia.org)
The term "semilunar" refers to an approximate half-moon shape of the valve leaflets. (wikipedia.org)
Each valve consists of a set of flaps (also called "leaflets" or "cusps") that open and close to enable blood to flow in the correct direction. (dan.org)
To quickly review, individuals with BAV have an aortic valve with 2 unequal-instead of the usual 3 equal sized-leaflets. (athletesheart.org)
This can lead to stretching apart of the valve leaflets and leakage at the valve, known as regurgitation . (athletesheart.org)

myocardial infarction caused by a was totally occluded by a thrombus thrombus of a mechanical mitral valve. (who.int)

Even when promptly recognized and treated, acute prosthetic valve failure is associated with a high mortality. (medscape.com)
Abrupt loss of function of the aortic valve results in acute aortic insufficiency and loss in the normal diastolic blood pressure resulting in a wide pulse pressure and bounding pulses. (wikipedia.org)
Angiotensin-converting enzyme genotype predicts valve damage in acute rheumatic fever. (cdc.gov)

Retinal arterial occlusive events caused by cholesterol, fibrinoplatelet or calcific emboli are known to occur in individuals with atheromatous vessels and aortic valves especially during or after interventional procedures such as cardiac catheterisation and coronary artery bypass graft procedures.

What are the indications of coronary angiography in aortic stenosis? (rimikri.com)
Although coronary embolism was performed because her chest pain tral prosthetic valve. (who.int)
In this paper, we report a rare case of myocardial infarction, which occurred as a result of a coronary embolism in a patient with prosthetic mitral valve thrombosis. (who.int)

INR of 1.6, myocardial infarction was mechanical valve surgery has increased cardial infarction. (who.int)

When the pressure in the left ventricle rises above the pressure in the aorta, the aortic valve opens, allowing blood to exit the left ventricle into the aorta. (wikipedia.org)
The aortic valve, between the left ventricle and the aorta. (dan.org)
Narrowing in ascending aorta or fibrous diaphragm just above aortic valve). (rimikri.com)
Aside from the problems with aortic valve stenosis or regurgitation or with enlargement of the aorta, individuals with BAV can also suddenly develop the problem of aortic dissection . (athletesheart.org)

The echocardiographic criteria for assessment of aortic stenosis severity are outlined below, in Table 2. (medscape.com)

The catheter-based solution for this condition is a procedure similar to angioplasty to open the clogged valve. (adventisthealth.org)
In the procedure, the cardiologist inserts or squeezes the valve along the catheter. (yashodahospitals.com)

The two most common valvular disorders in older adults are aortic stenosis and mitral regurgitation. (dan.org)
The symptoms of valvular disorders vary depending on which valve is affected as well as on the type and severity of the change. (dan.org)

However, in tran- due to mechanical valve thrombosis is continued despite medical treatment. (who.int)
