|---|---|
| heart valve prosthesis | An artificial substitute for a heart valve. It may be mechanical or composed of tissue. (12 Dec 1998) |
| heart valve prosthesis implantation | Surgical insertion of synthetic material to repair injured or diseased heart valves. (12 Dec 1998) |
| tilting disc valve prosthesis | A low profile artificial heart valve with excellent flow characteristics. (05 Mar 2000) |
| aortic valve | The heart valve that divides the left ventricle and the aorta. The aortic valve opens during left ventricular contraction and then closes to prohibit the backwash of oxygenated blood from the aorta into the ventricle. The aortic valve has 3 valve cusps. (27 Sep 1997) |
| aortic valve insufficiency | Backflow of blood from the aorta into the left ventricle, owing to imperfect functioning of the aortic semilunar valve. (12 Dec 1998) |
| aortic valve prolapse | The downward displacement of the cuspal material (misalignment of the cusps) below a line joining points of attachment of the aortic valve leaflets. The prolapsed cusp may occlude the ventricular septal defect during ventricular diastole. (12 Dec 1998) |
| aortic valve stenosis | Narrowing of the orifice of the aortic valve or of the supravalular or subvalvular regions. (12 Dec 1998) |
| bicuspid aortic valve | See: familial aortic ectasia syndrome. (05 Mar 2000) |
| blood vessel prosthesis | Prosthesis, constructed of either synthetic or biological material, which is used for the repair of injured or diseased blood vessels. (12 Dec 1998) |
| blood vessel prosthesis implantation | Surgical insertion of synthetic or biological material to repair injured or diseased blood vessels. (12 Dec 1998) |
| breast prosthesis | <oncology> An artificial breast form worn under clothing. (16 Dec 1997) |
| mandibular guide prosthesis | A prosthesis with an extension designed to direct a resected mandible into a functional relation with the maxilla. (05 Mar 2000) |
| mandibular prosthesis | A prosthetic appliance for the replacement of areas of the mandible missing or defective as a result of deformity, disease, injury, or surgery. (12 Dec 1998) |
| mandibular prosthesis implantation | Surgical insertion of an appliance for the replacement of areas of the mandible. (12 Dec 1998) |
