Question | Answer |
allograft: | heart valve replacement made from a human heart valve (synonym: |
annuloplasty: | repair of a cardiac valve’s outer ring |
aortic valve: | semilunar valve located between the left ventricle and the aorta |
autograft: | heart valve replacement made from the patient’s own heart valve (eg, the pulmonic valve is excised and used as an aortic valve) |
cardiomyopathy: | disease of the heart muscle |
chordae tendineae: | nondistensible fibrous strands connecting papillary muscles to atrioventricular (mitral, tricuspid) valve leaflets |
chordoplasty: | repair of the chordae tendineae |
commissurotomy: | splitting or separating fused cardiac valve leaflets |
heterograft: | heart valve replacement made of tissue from an animal heart valve (synonym: |
homograft: | heart valve replacement made from a human heart valve (synonym: |
leaflet repair: | repair of a cardiac valve’s movable “flaps” (leaflets) |
mitral valve: | atrioventricular valve located between the left atrium and left ventricle |
orthotopic transplantation: | the recipient’s heart is removed and a donor heart is grafted into the same site; the patient has one heart |
prolapse (of a valve): | stretching of an atrioventricular heart valve leaflet into the atrium during systole |
pulmonic valve: | semilunar valve located between the right ventricle and the pulmonary artery |
regurgitation: | backward flow of blood through a heart valve |
stenosis: | narrowing or obstruction of a cardiac valve’s orifice |
total artificial heart: | mechanical device used to aid a failing heart, assisting the right and left ventricles |
tricuspid valve: | atrioventricular valve located between the right atrium and right ventricle |
valve replacement: | insertion of a device at the site of a malfunctioning heart valve to restore blood flow in one direction through the heart |
valvuloplasty: | repair of a stenosed or regurgitant cardiac valve by commissurotomy, annuloplasty, leaflet repair, or chordoplasty (or a combination of procedures) |
ventricular assist device: | mechanical device used to aid a failing right or left ventricle |
xenograft: | heart valve replacement made of tissue from an animal heart valve (synonym:heterograft) |
