Invasive Hemodynamic Response to Transcatheter Edge-to-Edge Mitral Valve Repair

Overview

About this study

We hypothesize that (1) Patients with significant left atrial pressure (LAP) reduction during transcatheter mitral valve repair (TMVR) have lower cardiac output, more advanced diastolic dysfunction, increased left atrial stiffness, abnormal pulmonary vascular function and higher arterial afterload compared to TMVR patients without a significant LAP reduction. (2) TMVR and associated reduction in mitral regurgitation and LAP results in relief of pulmonary vascular congestion, and improvement in pulmonary vascular and right ventricular function.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Adults, age ≥ 40 years.
  • Severe, symptomatic primary mitral regurgitation identified by Doppler transthoracic echocardiogram:
    • Heart team (cardiologist and cardiac surgeon) agree that patient would be eligible for TMVR with MitraClip.
    • TMVR procedure will be performed in the cardiac catheterization laboratory for hemodynamic data recording.

Exclusion Criteria:

  • None.
