Mitral Valve Reconstruction in Chronic Heart Failure (CHF): Identification of Predictors for a Successful Therapy

Mitral Valve Reconstruction in Patients With Chronic Heart Failure and Secondary Mitral Insufficiency: Identification of Predictors for a Successful Therapy

The aim of the study is to evaluate hemodynamic and echocardiographic parameters in patients with secondary mitral insufficiency and CHF.

1. Identification of hemodynamic parameters as predictor for a successful mitral valve reconstruction in CHF patients.
2. Collection of clinical factors for the assessment of the postoperative course after mitral valve reconstruction in CHF patient.

5. Echocardiographic MI > II°
6. At least 1 hospitalization for heart failure before OP

Exclusion Criteria:

1. Secondary Cardiomyopathy by vitium cordis
2. Planned secondary procedure like CABG, aortic valve surgery, surgery of the tricuspid valve etc
3. Inclusion in another trial
