A Study to Remodel the Mitral Annulus following Robotic-Assisted Surgical Mitral Valve Repair


About this study

The purpose of this study is to investigate post-operative changes in cardiac structure and function for patients with mitral regurgitation to define heart remodeling.

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:

  • Adult male and female patients, 18 to 99 years of age.
  • Patients who previously underwent ECG-gated cardiac CT prior to robotic-assisted mitral valve repair for mitral regurgitation within past 10 years and have had surgical valve repair at least 6 months prior to follow-up CT exam.
  • Patients who are able and willing to sign the informed consent.

Exclusion Criteria:

  • Minors.
  • Patients unable to provide written informed consent.
  • Pregnancy (women of childbearing age will be required to have a urine pregnancy test prior to the CT examination due to radiation risk).
  • Compromised renal function, defined as eGFR ≤30 (3,4).
  • History of prior moderate or severe contrast reaction including: unresponsiveness, severe respiratory distress, convulsions, arrhythmia, cardiopulmonary distress, progressive angioedema, laryngeal edema, dyspnea, bronchospasm, symptomatic tachycardia, symptomatic bradycardia, hypotension, hypertensive crisis.
