Key result
Multidimensional echo indices differentiate MR severity in canine DMVD while 1D measurements fail below ~50% RF.
Why the study?
Describing the severity of mitral regurgitation in dogs with degenerative mitral valve disease is challenging.
Do multidimensional echocardiographic indices (RF, EROA, QMR:QAo) better quantify mitral regurgitation severity compared to 1-dimensional measurements in dogs with preclinical DMVD?
Observational (n=57)

Multidimensional echocardiographic indices (RF, EROA, QMR:QAo) can quantify mitral regurgitation severity in dogs with preclinical DMVD better than standard 1-dimensional measurements.

Multidimensional indices may aid MR grading in preclinical canine DMVD; leaves open outcome validation before practice change.
Larouche‐Lebel et al. (2019) conducted an observational in preclinical degenerative mitral valve disease (n=57). Multidimensional echocardiographic indices (RF, EROA, QMR:QAo) vs. 1-dimensional measurements (LA:Ao and LVIDdN) was evaluated on Correlation between 1-dimensional and multidimensional echocardiographic indices. Multidimensional echocardiographic indices (RF, EROA, QMR:QAo) differentiated MR severity in dogs with preclinical DMVD, whereas 1-dimensional measurements were insensitive until RF was ≥50%.
