In October, 1981, a 39-year-old man with mitral stenosis was hospitalized for mitral valve replacement. 

Medical treatment of mitral regurgitation with afterload reduction and diuresis can effectively alleviate symptoms, but has not been shown to prolong survival. The currently recommended treatments for severe mitral regurgitation are surgical mitral valve repair or replacement. Mitral valve replacement with either a bioprosthetic or mechanical valve has the inherent drawbacks of a potential increase in periprocedural... 

The idea of percutaneous mitral valve replacement may be more challenging than mitral valve repair techniques due to the unique shape and location of the mitral valve and associated apparatus. The Endovalve-Hermann mitral valve replacement system (Endovalve Inc., Princeton, NJ) is a bioprosthetic foldable redeployable valve that allows antegrade trans-septal placement via a 24 French sheath. An early animal study in four sheep has been reported by Hermann at TCT 2007 (Figure 7.8). 

In addition, a recent publication described the feasibility of placing a transcatheter bioprosthetic valve at the site of a surgical mitral valve replacement in a bovine model (37). This type of approach may eventually be used in lieu of repeat open surgical replacement for patients with a failing mitral valve bioprosthesis.

A 60-year-old woman taking digoxin, furosemide and warfarin (ESTR 3.5 to 5) developed a fever after mitral valve replacement surgery and was given rifampicin 450 mg twice daily and teicoplanin 400 mg twice daily. Within 3 days her ESTR began to fall and by day 6 the anticoagulant effect was completely lost. Despite progressive warfarin increases to 10, 15, and then 20 mg daily, her INR stayed between 1.2 and 1.6, even when the rifampicin was stopped, and remained low for a further 20 days, at whieh point the teicoplanin was also stopped. ...

Some other examples of animal models that are used in biotextile retrieval studies include implanting hernia repair meshes in the abdomen of piglets and mitral valve replacement in juvenile sheep or calves, and subcutaneous implants of valve materials in young rats for in vivo biocompatibility and calcification studies. 

Mitral regurgitation is a typical complication of dilated heart disease in which backflow of the blood from the ventricle into the atrium further contributes to the excessive volume load and progression of the disease. Mitral valve replacement or repair is thus one of the most common operations in advanced cardiac failure and is performed either alone or in combination with other procedures. While MDCT does not allow visualization of the regurgitant jet, it can provide basic information on the morphology of the valve structures and movement of the leaflets (Fig. 19.7).

According to the 2006 ACC/AHA guidelines for the management of patients with valvular heart disease, mitral valve replacement (MVR) is recommended for patients with moderate to severe mitral stenosis (M VA <1.5 cm ), if the patient is not suitable for percutaneous mitral balloon valvulotomy and is not a high-risk candidate [17]. For chronic mitral regurgitation, MVR is only recommended if a patient with LV dysfunction (ejection fraction <0.60 and/or end systolic dimension >40 mm) is deemed not suitable for mitral valve repair.
