2016 ACVIM Forum Research Abstract Program

Results from this study indicate that the severity of MMVD or the presence of pulmonary hypertension did not negatively affect lifespan after bronchial stent placement. As such, moderate to severe MMVD and the presence of pulmonary hypertension should not be viewed as exclusion criteria when assessing candidates for possible bronchial stenting. Prospective studies should be conducted to further investigate the clinical benefit of bronchial stenting in dogs with severe bronchial collapse. Dogs with naturally acquired tricuspid regurgitation (TR) were studied prospectively. All dogs had degenerative valve disease. Target variables were acquired during 4 study periods (dogs in lateral recumbency or standing, after a 6-minute walk test and after sedation [0.25 mg/kg butorphanol, IM]), and by two different observers. Heart rate (HR), TR flow velocity (TRFV), PVR, estimates of right atrial pressure, stroke volume, cardiac output, and 23 other variables were quantified. Statistical methods included repeated-measures ANOVA and mixed model analysis. P < 0.05 was considered significant.
