Implication
May support 3D-FVCD for MR quantification in >moderate cases; leaves open prospective validation against PC-CMR before clinical adoption.
Structured PICO
Does automated quantification of mitral regurgitation using 3D-FVCD provide accurate measurements compared to PC-CMR and 2D echocardiography in patients with >moderate MR?
P
Population
32 patients with more than a moderate degree of mitral regurgitation assessed by transthoracic echocardiography
I
Intervention
Real-time three dimensional full volume color Doppler (3D-FVCD) echocardiography for automated quantification of mitral regurgitation
C
Comparator
Two dimensional (2D) Doppler TTE (PISA and volumetric methods) and phase contrast cardiac magnetic resonance imaging (PC-CMR)
O
Outcome
Mitral regurgitant volume and its correlation/agreement between 3D-FVCD and PC-CMRsurrogate
Automated 3D-FVCD echocardiography is a feasible and accurate method for quantifying mitral regurgitation, showing better agreement with cardiac MRI than standard 2D methods.
