[Current surgical treatment for acquired valvular heart disease].

We discuss the current status of surgical treatment for acquired valvular heart disease. Mitral valve repair for organic and functional mitral regurgitation is the first choice instead of valve replacement. It is important that surgery for functional mitral regurgitation restores the geometry of the left ventricle and mitral valve. The reduction of mitral valve tethering for functional mitral regurgitation is a current topic of discussion. At present, the surgical procedure for both aortic stenosis and aortic regurgitation is valve replacement in most cases, although aortic valve repair has been attempted for aortic regurgitation in recent years. The early results of aortic valve repair are excellent, but the long-term results have not been clarified. The durability of valve repair in both the mitral and aortic position is a future issue and it may be improved by revising the indications for valve repair and using new surgical techniques.
