The investigators evaluate the changes of echocardiographic and sleep apnea parameters after mitral valve surgery. The patients undergo echocardiographic and sleep apnea control before surgery. After a period of 3-5 months, they undergo a second echocardiographic and sleep apnea control and the results are evaluated.
