5-Year Follow-Up Safety and Performance Evaluation of the Medtentia Annuloplasty Ring in Adults

Single-center clinical investigation is to evaluate long-term safety and performance of the Medtentia Annuloplasty Ring (MAR) in 11 patients who underwent successful mitral valve (MV) surgery using Medtentia's MAR system in clinical investigation 2010-040 performed during June 2011 - April 2016.

Inclusion criteria

  • Signed Informed Consent Form.
  • Subject had a successful MAR implantation in clinical investigation 2010-040.
  • Subject is willing to participate in the follow-up study and to comply with the requirements of the Clinical Investigation Plan.

Exclusion criteria

Treatment and study plan

Medtentia Annuloplasty Ring (MAR)

Device

Mitral valve repair using the MAR performed in clinical investigation 2010-040

Primary outcomes

  1. Safety: the Occurrence, Nature and Frequency of Significant Medical Events

    Time frame: since the last visit of clinical investigation 2010-040 to more than 5 years post-procedure

  2. Performance: Change in Mitral Regurgitation (MR) as Measured by Trans-Thoracic Echocardiography (TTE)

    Time frame: from 2-year follow-up data point to more than 5 years post-procedure

    Success will be defined as no change or any improvement in MR class as described in the American College of Cardiology/ American Heart Association (ACC/AHA) Guidelines

Secondary outcomes

  1. Safety: All-Cause Mortality

    Time frame: since the last visit of clinical investigation 2010-040 to more than 5 years post-procedure

    Collected retrospectively

  2. Safety: the Occurrence, Nature and Frequency of Adverse Device Effects (ADEs) and/or Device Deficiencies

    Time frame: since the last visit of clinical investigation 2010-040 to more than 5 years post-procedure

  3. Safety: Number of Cardiovascular Admissions

    Time frame: since the last visit of clinical investigation 2010-040 to more than 5 years post-procedure

  4. Safety: the Number of Subjects With Clinically Significant Abnormal Findings

    Time frame: day of study visit

    The number of subjects with clinically significant abnormal findings in TTE, electrocardiography (ECG), or vital signs and type of abnormal findings will be listed and tabulated

  5. Performance: Change in Mitral Regurgitation Parameters (Left Ventricle Reverse Remodeling), as Measured by TTE

    Time frame: since the last visit of clinical investigation 2010-040 to more than 5 years post-procedure

    Change from the clinical investigation 2010-040 2-year follow-up in the following MR parameters, as measured by TTE:

    • Left ventricle reverse remodeling: left ventricular inner dimension systole and diastole (the dimension of inner edge to inner edge, perpendicular to the long axis of the left ventricle, at the level of the mitral valve leaflet tips, measured at end-systole and end-diastole)
  6. Performance: Changes in New York Heart Association (NYHA) Classification When Compared to the Clinical Investigation 2010-040 2-year Follow-Up Visit

    Time frame: since the last visit of clinical investigation 2010-040 to more than 5 years post-procedure

    Defined as assessment of NYHA functional class status at clinical Investigation 2010-040 2-year follow-up visit and at this investigation visit more than 5 years post-procedure

    Class I: Patients with cardiac disease but without resulting limitations of physical activity.

    Class II: Patients with cardiac disease resulting in slight limitation of physical activity. Patients are comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea, or anginal pain.

    Class III: Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary physical activity causes fatigue, palpitation dyspnea, or anginal pain.

    Class IV: Patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of cardiac insufficiency or of the anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort is increased.

  7. Performance: Number of Subjects With Recurrence of Mitral Regurgitation

    Time frame: since the last visit of clinical investigation 2010-040 to more than 5 years post-procedure

    Recurrence of mitral regurgitation is defined as changing of mitral regurgitation to moderate or severe according to ACC/AHA classification determined by TTE

  8. Performance: Change in Mitral Regurgitation Parameters (Coaptation Height), as Measured by TTE

    Time frame: since the last visit of clinical investigation 2010-040 to more than 5 years post-procedure

    Change from the clinical investigation 2010-040 2-year follow-up in the coaptation height, as measured by TTE

Other outcomes

  1. Number of Subjects With Re-operation or Mitral Valve Reintervention Due MAR Performance Failure or Malfunction

    Time frame: since the last visit of clinical investigation 2010-040 to more than 5 years post-procedure

  2. Quality of Life Scores as Measured by the 15D© Questionnaire

    Time frame: day of study visit

    15D© questionnaire investigates the standard of quality of life (QOL15D) through a general health assessment and not specific to a particular disease or age. It is a 15-domain (mobility, vision, hearing, breathing, sleeping, eating, speech, excretion, usual activities, mental function, discomfort and symptoms, depression, distress, vitality and sexual activity) questionnaire. Each domain score ranges from 1 (no problems) to 5 (extreme problems), with lower scores reflecting better health-related functional status.
