About this study

The purpose of this study is to compare the value and practicality of using 3D color doppler echocardiography of the vena contracta area versus the standard 2D method when needing accurate measurement of mitral valve regurgitation.

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. If you need assistance understanding the eligibility criteria, please contact the study team.
