Murmur intensity in small-breed dogs with myxomatous mitral valve disease
reflects disease severity
by Ingrid Bersås Ljungvall, Mark Rishniw, Francesco Porciello, Luca Ferasin and Dan G. Ohad
Soft murmurs in
According to this study, a clinician ausculting a soft mitral murmur in a small-breed dog with MMVD can reasonably conclude that the disease severity is mild and that CHF is extremely unlikely.
Objectives: To determine whether murmur intensity in small-breed dogs with myxomatous mitral valve disease reflects clinical and echocardiographic disease severity.
Methods: Retrospective multi-investigator study. Records of adult dogs ≤20 kg with myxomatous mitral valve disease were examined. Murmur intensity and location were recorded and compared with
echocardiographic variables and functional disease status.
Murmur intensities in consecutive categories were compared
for prevalences of congestive heart failure, pulmonary
hypertension and cardiac remodelling....

LA:Ao and heart murmur
Increasing murmur intensity is associated with increasing left atrial size, as determined by the left-atrial-to-aortic ratio (LA:Ao). The black line denotes the median value, the ...
