2. Valve replacement - Wikipedia

   en.wikipedia.org/wiki/Valve_replacement

   Valve replacement surgery is the replacement of one or more of the heart valves with either an artificial heart valve or a bioprosthesis (homograft from human tissue or xenograft e.g. from pig). It is an alternative to valve repair .

3. Tricuspid valve - Wikipedia

   en.wikipedia.org/wiki/Tricuspid_valve

   The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...

4. Valvulotomy - Wikipedia

   en.wikipedia.org/wiki/Valvulotomy

   A valvulotomy, valvotomy, [1] valvuloplasty, or valvoplasty is a procedure used in heart valve surgery that consists of making one or more incisions at the edges of the commissure formed between the two (mitral valve), or three tricuspid valve leaflets. This relieves the constriction of valvular stenosis (especially mitral valve stenosis ...

5. Artificial heart valve - Wikipedia

   en.wikipedia.org/wiki/Artificial_heart_valve

   An artificial heart valve is a one-way valve implanted into a person's heart to replace a heart valve that is not functioning properly (valvular heart disease). Artificial heart valves can be separated into three broad classes: mechanical heart valves, bioprosthetic tissue valves and engineered tissue valves.

6. Heart valve repair - Wikipedia

   en.wikipedia.org/wiki/Heart_valve_repair

   Mitral valve repair is mainly used to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. [citation needed] A mitral balloon valvuloplasty enlarges the valve opening to allow greater oxygenated blood flow into the left ventricle, and since severe mitral regurgitation can be a major complication, degrees of stenosis, regurgitation, and valve anatomical features are taken ...

7. Tricuspid valve stenosis - Wikipedia

   en.wikipedia.org/wiki/Tricuspid_valve_stenosis

   Tricuspid valve stenosis itself usually does not require treatment. If stenosis is mild, monitoring the condition closely suffices. However, severe stenosis, or damage to other valves in the heart, may require surgical repair or replacement. The treatment is usually by surgery (tricuspid valve replacement) or percutaneous balloon valvuloplasty ...

8. Tissue engineering of heart valves - Wikipedia

   en.wikipedia.org/wiki/Tissue_engineering_of...

   Using a decellularized porcine xenograft valve, also called Matrix P, in adults with a median age of 46 years, the aim of the study was to offer a proposal for pulmonary valve replacement. While some patients died postoperatively and had to undergo reoperation, the short-term results appear to be going well as the valve is behaving similarly to ...

9. Fontan procedure - Wikipedia

   en.wikipedia.org/wiki/Fontan_procedure

   The Fontan Kreutzer procedure is used in pediatric patients who possess only a single functional ventricle, either due to lack of a heart valve (e.g. tricuspid or mitral atresia), an abnormality of the pumping ability of the heart (e.g. hypoplastic left heart syndrome or hypoplastic right heart syndrome), or a complex congenital heart disease where a bi-ventricular repair is impossible or ...
