Plain-English summary
A group of 49 dogs with degenerative mitral valve disease (MVD) had their blood pressure measured using three different methods: mitral regurgitation velocity, high definition oscillometry, and Doppler ultrasonography. The study found that while there were some correlations between the measurements, they were not strong enough to use them interchangeably. This means that if your dog has MVD, the way blood pressure is measured can affect the results, and it's important to use the same method consistently for accurate monitoring.

Abstract
INTRODUCTION: To determine if systolic blood pressure estimated by mitral regurgitation (MR) velocity can be used interchangeably with that estimated by high definition oscillometry (HDO) and Doppler ultrasonography (DU) in dogs with naturally occurring mitral valve disease (MVD). ANIMALS: Forty-nine client-owned dogs with naturally occurring MVD. MATERIALS AND METHODS: This is a retrospective study. Medical records were reviewed and dogs with MR caused by degenerative MVD were included if systolic blood pressure was estimated from MR velocity determined by continuous wave Doppler (CW), DU and HDO at the same visit. A Pearson product moment correlation coefficient was determined for each combination of measures and tested for significance with a paired t-test. Limits of agreement between 2 measures were determined by the 95% confidence interval of the average difference of the means and illustrated by Bland-Altman plots. RESULTS: Systolic pressure estimated from CW was significantly but only moderately correlated to DU (r = 0.42, p=0.0015) and HDO (r = 0.40, p=0.0021). Pressure estimated from DU was significantly but only moderately correlated to HDO (r = 0.57, p≤0.0001). Limits of agreement were wide for all measures including DU and CW (-61.9to 44.6 mmHg), HDO and CW (-65.2to 26.9 mmHg), and HDO and DU (-63.1 to 42.06 mmHg). DISCUSSION: Systolic blood pressure estimated by CW cannot be used interchangeably with HDO or DU in dogs with naturally occurring MVD.
