Echocardiographic Parameter and Sleep Apnea Changes After Mitral Valve Surgery

Zisis Dimitriadis132 enrolled

Overview

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.
