Multimodality Evaluation of Left Ventricular Remodeling

Overview

About this study

The purpose of this study is to use a multimodal approach to mitral valve evaluation using cardiac CT and MRI, which have shown superior accuracy in assessing anatomic and functional parameters relative to standard-of-care echocardiography. By evaluating 30 patients undergoing robotic mitral annuloplasty, this study aims to establish the feasibility of further prospective evaluation of CT and MRI for preoperative risk stratification. Enhanced risk stratification could significantly improve patient outcomes.

 

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:

  • Age >= 18
  • Male or Female
  • A diagnosis of severe chronic primary mitral regurgitation
  • Undergoing isolated robotic mitral annuloplasty at Mayo Clinic Rochester
  • Patients must have the ability to consent or have an appropriate representative available to do so

Exclusion Criteria:

  • Prior valve intervention
  • Concomitant valve surgery ate the time of mitral annuloplasty (e.g. tricuspid annuloplasty, aortic valve replacement
  • Concomitant >= moderate regurgitation or stenosis in any other valve by preoperative echocardiography
  • History of prior myocardial infarction
  • History of cardiomyopathy unrelated to mitral regurgitation (e.g. dilated, hypertrophic, infiltrative)
  • Pregnancy. Women of childbearing potential will be verbally screened by clinical staff during as part of routine pre-MRI evaluation. If a subject is unsure whether they could be pregnant, a negative pregnancy test will be performed prior to scanning
  • Implantable devices that would be a contraindication to MRI
  • Severe allergy to gadolinium MRI contrast

Note: Other protocol defined Inclusion/Exclusion Criteria may apply.
