OPtimisation of Surgical Repair for Treating Insufficiency of the MItral Valve - Safety Evaluation

February 25, 2021 updated by: Kephalios

OPtimisation of Surgical Repair for Treating Insufficiency of the MItral Valve - Safety Evaluation (OPTIMISE)

The optimal surgical approach in functional mitral regurgitation (MI) was questioned in favour for prosthetic replacement due to the reduced risk of recurrent MI . However, adjustable mitral rings may provide an alternative . In this first-in-man trial, a novel balloon-adjustable mitral-ring was assessed regarding clinical safety and feasibility. 5 patients will be enrolled according to the inclusion/ exclusion criteria and subsequently implanted with the study device. Study visits will be performed preoperatively, perioperatively, at discharge, at 30 days, 3 months and 6 months. Primary outcome parameter will be morbidity and mortality at 30 days following implantation.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Experimental: Implanted Patients
Implantation of Kephalios Device 1
Device: Kephalios Device 1
The Kephalios Device 1 is an adjustable annuloplasty ring, to be implanted by open surgery, having a hollow structure that comprises a flat rigid ring surrounding a deformable cage. The unique feature of the Kephalios Device 1 is that its annular shape and dimension can be finely adjusted percutaneously by an external actuator (three-balloon catheter) independently in the three areas corresponding to P1, P2 and P3
