What is a replacement of the aortic valve?

AVR. Exactly what it says. If there is a problem with the aortic valve (between left ventricle and aorta) (either narrowed -stenotic- or leaking -insufficient) it can be surgically replaced. It can be replaced with a mechanical "metal" or tissue valve "pig valve".
A procedure.... Aortic valve replacement usually involves surgically removing a patients own diseased aortic valve and replacing it with a valve constructed fom metal or cow tissue. Sometimes a human valve is used (homografts). More recently, aortic valves have been replaced by stenting, a non-surgical technique in higher risk individuals.

How dangerous is an aortic valve replacement?

Reasonably safe. Generally aortic valve replacement is a reasonably safe procedure. The operative risks however depends on the overall condition of the heart, age, presence or absence of other problems such as lung and kidney disease and the overall physical strength of the patient. In most cases the surgical risk should be less than 5% chance of a bad outcome. Read more...

Aortic valve replacement done with pig or fake one?

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...

What happens during, and after an aortic valve replacement?

Aortic valve sx. The native aortic valve is surgically removed and replaced with a mechanical valve or a bioprosthetic valve. Mechanical valves last a life time but need anticoagulation with coumadin (warfarin). Read more...
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...

Straight forward. The aortic valve is replaced by instituting cardiopulmonary bypass and cardioplegic arrest. The aorta is cut open after stopping the heart, the diseased valve and calcium is removed, the aortic anulus is sized and a tissue valve or a mechanical valve is sewn in place, co2 flush used to aid deairing, aorta closed, heart restarted, cpb discontinued, hemostasis accomplished and wound closed.
