The TSD-5 is intended to secure ePTFE sutures on the mitral valve for the treatment of mitral valve disease.

Inclusion criteria

• All subjects referred for mitral valve surgery
• Presence of severe mitral regurgitation as read on an echocardiographic study performed within 60 days prior to procedure. Assessment of mitral regurgitation will be performed by the investigational site echocardiography laboratory and confirmed by the Core Echocardiography Laboratory using an integrative method.
• Age > 18 years
• Estimated post-ePTFE cordal implantation coaptation surface is adequate in the judgment of the operating surgeon and the patient eligibility committee
• Degenerative mitral valve disease
• Subject is able to sign informed consent and able to return for follow-up and is capable of participating in all testing associated with this clinical investigation
• Women of child-bearing potential have a negative pregnancy test

• ST segment elevation myocardial infarction requiring intervention within 30 days prior to enrollment
• Evidence of cirrhosis or hepatic synthetic failure
• Pregnancy at the time of enrollment (women of child bearing age should have negative pregnancy within 14 days of surgery)
• Severe pulmonary hypertension (PA systolic pressure > 70 mmHg)
• Previous cardiac surgery, or surgery on the left pleural space

• Patient is participating in another clinical study for which follow-up is currently ongoing. (Co-enrollment in an investigational device or interventional study)
• Patient with non-cardiac co-morbidities and life expectancy < 1 year
• Patient has a condition or conditions that, in the opinion of the Investigator, preclude participation, including willingness to comply with all follow-up procedures
