NCT02453451

Brief Summary

Patients received a MitraClip procedure because of a leakiness of their mitral valves. During this procedure the atrioventricular valves were stuck together permanently via a clip which leads to a reduction of leakiness. As a result of this procedure a small hole remains at the cardiac septum which is called an atrial septal defect (ASD). In most cases the hole will close after a few weeks or months, but in many other cases not. Until now there is no exact data about the effect of this hole on the filling pressure in the heart or on the blood flow behaviour. So the aim of this study is a precise analysis of the blood flow mechanics during and after the MitraClip procedure to identify criteria to get more informations for a better strategy and regulation of the MitraClip procedure.

Outcome Measures

Primary Outcomes (1)

    after 6 months

  • quality of life

    after 6 months

  • change from baseline in the ASD area at 6 months

    after 6 months

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • patients in which a percutaneous mitral valve reconstruction via the MitraClip system shall be performed due to severe mitral insufficiency because a conventional surgery would be too stressful for them
  • legal age (≥18 years)
  • written informed consent prior to study participation
  • subjects who are contractually capable and mentally able to understand and follow the instructions of the study personnel

You may not qualify if:

  • malignant diseases
  • varicose veins of the esophagus
  • patients with central nervous system dysfunction
  • pregnant and lactating females
  • subject has been committed to an institution by legal or regulatory order
  • dependency or working relationship with the investigator
  • participation in a parallel interventional clinical study
