Abstract

Myxomatous mitral valve disease (MMVD) is a prevalent heart condition in dogs, particularly affecting the mitral valve. Stage B1 of MMVD, as per the American College of Veterinary Internal Medicine (ACVIM) guidelines, encompasses asymptomatic dogs with structural heart disease. This stage is characterized by a range of radiographic and echocardiographic findings without significant cardiac remodeling. Despite its prevalence, the impact of MMVD Stage B1 on cardiac weight remains unclear. In this study, 28 dogs were examined to evaluate if MMVD Stage B1 correlates with abnormal increases in heart weight postmortem. Dogs were clinically examined, underwent echocardiography, and were divided into two groups based on MMVD staging. Heart weight relative to body weight (hW/bW) was assessed. Results revealed that MMVD Stage B1 had minimal impact on heart weight, with hW/bW ratios remaining within normal ranges. Notably, despite differences in breed, sex, and age, hW/bW ratios did not significantly deviate from normal values. This study provides valuable insights into the relationship between MMVD Stage B1 and cardiac weight in dogs, indicating the need for further investigations with larger sample sizes to validate these findings. Understanding cardiac weight alterations in MMVD can aid in refining diagnostic and management approaches for affected dogs.
