Diagnostic and Prognostic Value of Several Color Doppler Jet Grading Methods in Patients With Mitral Regurgitation
Section snippets
Methods
Transthoracic echocardiography was performed prospectively at Ghent University Hospital in 476 patients with MR of different etiologies, of whom 254 patients with PMR (136 with mitral valve prolapse and 118 with nonprolapse degenerative MR) and 223 heart failure patients with ejection fraction <50% and SMR. The study was approved by the local Ethics Committee.
We performed an online survey among 50 Belgian cardiologists on the use of all possible echocardiographic approaches for grading MR.
The
Results
The results from the online survey on echocardiographic MR grading show that all cardiologists (100%, n = 50) used “eyeballing” for color Doppler assessment of the MR jet (BEG), whereas only 14% performed additional MR jet area measurement. Notably, 86% of the cardiologists assessed the severity of MR with any color Doppler method, which was much more frequent than the VCW (applied by 36% of cardiologists), PISA-based methods (34%) and quantitative Doppler (8%).

Discussion
The present study is the first comprehensive comparative analysis of various color Doppler methods and quantitative grading methods in predicting outcome in both PMR and SMR.
Our online survey showed that among cardiologists, color Doppler grading of the MR jet in the LA appears to be the most applied method for grading MR severity in clinical practice. This is in line with the study from Wang et al. who showed that up to 90% of echocardiographers use color Doppler jet assessment for MR grading,
