Abstract
Fatal hemodynamic mitral stenosis and mitral regurgitation of all etiologies can be successfully treated by cardio-surgical operations, plasty or mitral valve replacement. In the case of mitral stenosis, it is mostly necessary to replace the valve by a mechanic valve or by a bio-prothesis, since only patients with a heavily calcificated mitral valve which is not suitable for ballon valvuloplasty are indicated for operation at present.
On the contrary, in the previous majority of patients with mitral regurgitation the operations preserving a valve, i.e., various types of plasty, are possible. In the case of permanent but even paroxysmal or persistent atrium fibrillation its radio frequency or cryopallidectomy detachment is performed simultaneously by minor surgery on the mitral valve.
