If you have an elderly patient where long term durability is less important, what valve would you use? Bio or mechanical?

Bio

If you have a young adult or children needing a valve, not woman in child bearing years, what kind of valve is usually used? Bio or mechanical

Mechanical

If a patient is requiring aortic root replacement, such as aortic dissection with severe aortic insufficiency, what valve would you use? Bio or mechanical?

Mechanical

Patients with chronic anticoagulant problems should use what kind of valve?

Bio, because they can't take blood thinners

Patients who have renal failure, or a small valve annulus, or are on blood thinners already would receive which valve?

Mechanical

Types of bioprosthetic valves are _____, ______, and______.

Autograft (self to self)


Homograft (allograft)


Heterograft ( xenograft)

With an autograph valve, they take an individual's pulmonic valve annulus and trunk relocate it to the ____ valve position. This also involves repositioning of the _____ _____. This is known as the_____ procedure.

Aortic


Coronary arteries


Ross procedure

With autograft the remove the ____ _____ (thigh muscle covering) and utilize it as a bioprosthetic heart valve.

The benefit of the stentless valves is improved hemodynamics with a ____ PG.

Decreased

With a homograft valve, they appear very similar to a____

Native valve

They use a _____ to take over for the heart and lungs.

Cardiopulmonary bypass machine

With heterograft valves, they use a ______ valve or ____ valve.

Porcine (pig)


Bovine (cow)

With porcine valves they use the pigs _____ _____ valve that may be mounted on stents or stentless.

Medtronic


Hancock


Ionescu-shiley


Edwards prima plus


Toronto SPV

Always compare prior echos to see if any changes occurred with bioprosthetic valves. When should the patient have an echo after getting new bio valve?

Soon after valve repair so baseline can be documented

What can happen to bio valves that cause complications?

Calcification

A normal amount of ____ is present in most bio valves. A _____ small jet is considered normal.

Regurg


Single

All prosthetic valves are inherently _____.

Stenotic

_____ occurs when the sutures in the sewing ring become looser and the prosthesis is no longer stable. This causes a ____ leak.
