What this trial studies

This study evaluates the safety and performance of the MIA Minimally Invasive Annuloplasty Device in patients suffering from chronic functional tricuspid regurgitation. It is a prospective, multi-center study where participants will undergo clinical assessments at 1 month, 6 months, and 1 year following the implant procedure. The study aims to determine the effectiveness of this device in improving patient outcomes related to heart function.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 with moderate to severe chronic functional tricuspid regurgitation who are undergoing cardiac surgery.

Not a fit: Patients with severe uncontrolled hypertension, previous tricuspid valve repairs, or recent myocardial infarction may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve heart function and quality of life for patients with tricuspid regurgitation.

How similar studies have performed: Other studies have shown promise with similar minimally invasive approaches, indicating potential for success in this area.
