Brief summary
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.
Interventions
PROCEDUREEchocardiographic and sleep apnea test
Echocardiographic evaluation (Vivid 7, GE) of systolic and diastolic function of both ventricles as well as evaluation of apnea-hypopnea index and type of apnea (ApneaLink®)
