Aortic valve replacement - tissue or mechanical better?

Aortic valve replacement - tissue or mechanical better?

AVR: Aortic valves can be replaced with either mechanical valves or bio prosthetic, taken from animals and treated to prevent rejection. There are different reasons for choosing either valve such as age and treatment with anticoagulants. Individuals who do not wish to be on meds such as Coumadin (warfarin) may have a bioprosthetic valve, however, younger individuals usually have mechanical valves. ...Read more

Valve (Definition)

A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more

Bovine or mechanical valve for my mitral valve replacement surgery. Which is best?

Bovine or mechanical valve for my mitral valve replacement surgery. Which is best?

Depends: The type of valve chosen depends on many factors ; age, other medical problems the type of valve disease, regurgitation/stenosis or some combination as well as pt preference. Pt . Preference is important when it come to anticoagulation long term after valve surgery with a mechanical valve. If anticoagulation is not feasible or the pt does not want it then a bovine or tissue valve is the way togo. ...Read more

Which percentage of mitral valve regurgitation patients require valve repair or replacement surgery?

Which percentage of mitral valve regurgitation patients require valve repair or replacement surgery?

Depends: It depends on the severity of the mr patients have and what their ages are. If you take the general usa population, all adults over age 21, some degree of mr is present in >80% (most of it trivial or very mild). Among that unselected group. ...Read more

Is bicuspid aortiic valve replacement like mitral valve replacement?

NO.: Aortic valve replacement in a patient with a bicuspid aortic valve may require repair of an ascending aortic aneurysm if present. Although valves are sewn in place the same, the location is totally different with particular anatomic differences. The mitral closes in systole and the aortic valve in diastole. For the mitral need to actually open the heart. For the aortic its done thru the aorta. ...Read more

Is bicuspid aortiic valve replacement similar to mitral?

Valve replacement: The surgery replaces the valve with either a mechanical or animal tissue valve. This is done on a heart lung machine. The valve takes the place of the damaged valve and the patient lives their life with a new disease 'artificial valve' with its own set of problems. The obstruction or valve leak of the diseased valve is corrected by the artificial valve. Sometimes blood thinners are needed. ...Read more

What are the pros and cons of mechanical valve vs tissue valve?

What are the pros and cons of mechanical valve vs tissue valve?

Broadly speaking,: mechanical valves last longer but require oral anticoagulation with warfarin. tissue valves do not last as long, but do not require oral anticoagulation. the decision is a complex one that is best made with the advice of a physician. ...Read more

Is there any difference between a bicuspid aorticvalve replacement and mitral valve replacement surgery?

Is there any difference between  a bicuspid aorticvalve replacement and mitral valve replacement surgery?

Yes: The aortic valve and the mitral valve are two completely different valves. Whereas bicuspid aortic valve surgery usually requires replacement, the preferred approach to mitral valve surgery, unless for severe stenosis or severe mitral regurgitation in a minority of instances, is mitral valve repair. A very experienced opinion is often required. ...Read more

What is an aortic valve replacement?

What is an aortic valve replacement?

Surgical procedure : Aortic valve replacement is a surgical operation where the heart is stopped while the body is on cardiopulmonary bypass machine. The diseased valve is cut out and a new prosthetic valve from a pig or cow or a mechanical valve is sewn in. The operation takes 3-4 hours to complete and you can stay in hospital for 4-7 days. ...Read more

Will a torn chordae tendineae of mitral valve from endocarditis heal without surgery ?

Chorda tendinae: A ruptured chorda tendinae would be very unlikely to reattach. If the mitral insufficiency produced is signficant volume and it usually is, surgical intervention is most often necessary. Some folks with ruptured chordae don't need immediate surgery but eventual surgery remains likely. ...Read more

Heart valve replacement. Which valves need it most?

Heart valve replacement. Which valves need it most?

Heart valves: The mitral and aortic valves are the most often replaced valves, but sometimes the mitral valve can be repaired, but not the aortic valve. So probably the aortic is the most replaced. It is much less common that the pulmonary or tricuspid valve be replaced. ...Read more

Are there any treatments for aortic stenosis other than surgery or percutaneous aortic valve replacement?

Are there any treatments for aortic stenosis other than surgery or percutaneous aortic valve replacement?

Long term, no: For "critical aortic stenosis" (valve area less than .7cm2) surgery, and occasionally valvuloplasty is the only curative treatment. Prior to the critical phase of aortic stenosis, the condition is temporized with medications that support overall heart function. ...Read more

How is the decision made between which type of valve a surgeon replaces i.E tissue versus mechanical

Depends: The decision is made when taking into account the age of the patient and co-morbidities. Typcially, patients over the age of 65 are best served with a tissue valve, whereas younger patients would do better with a mechanical. The reason is that this minimizes the chance that the patient will have to have a re-do procedure. ...Read more

How is a small aortic annulus or root handled when doing aortic valve replacement? Do the 19mm or 17mm valves flow badly? More risks?

Cardiac surgeon: Small aortic annulus is identified by echocardiography. Your cardiac surgeon will plan to enlarge the annulus to accommodate the largest valve practical. Sometimes even cutting into the heart like a ross/konno is required. All surgery has risks but your surgeon will be everything possible to help you, remember they have dedicated themselves to this job. Hope this helps. ...Read more

Aortic Valve (Definition)

The aortic valve is one of 4 valves in the heart, each of which separates 2 cardiac chambers. It opens when blood is actively ejected from the left ventricle into the aorta artery, to be carried to the rest of the body. It then closes firmly to prevent blood from flowing backwards, while it passively continues to flow forward to body's vital organs. When next heartbeat ...Read more


Tissue (Definition)

The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more
