Oct 14, 2009 · Vertebral Heart Size (VHS) is a number that normalizes (indexes) heart size to body size using mid-thoracic vertebrae as units of measure (Figure 1). Various authors also have called VHS an acronym for vertebral heart score, vertebral heart sum or …

Apr 8, 2016 · The original guidelines for VHS were designed to be applicable across breeds and conformations, and most dog breeds studied individually fall within the normal range. However, several breeds have normal VHS values that would suggest cardiomegaly using the original scale.

some breeds have normal VHS values that would commonly suggest cardiomegaly. The table below summarises the breed-specific normal values where these have been developed and published. Use this table when interpreting the VHS in your MVD patients to determine whether cardiomegaly is present. BREED-SPECIFIC VERTEBRAL HEART SCORES (VHS)

Breed-specific values for vertebral heart score (VHS), vertebral left atrial size (VLAS), and radiographic left atrial dimension (RLAD) in pugs without cardiac disease, and their relationship to Brachycephalic Obstructive Airway Syndrome (BOAS)

Jul 6, 2022 · To improve accuracy of assessing cardiac chamber enlargement, surrogate quantitative radiographic measurement of cardiac size such as vertebral heart size (VHS) and vertebral left atrial size (VLAS) are useful.

Sep 21, 2012 · The vertebral heart score (VHS) measurement is commonly used to provide a more objective measurement of cardiomegaly in canines. However, several studies have shown significant breed variations from the value previously established by …

Vertebral heart scale (VHS) is an objective measurement of cardiac size on thoracic radiographs against recorded normal measurements to assess for cardiomegaly. When used in combination with a thorough medical history and physical examination, VHS is useful for identifying possible heart disease and monitoring changes in heart size over time in ...

Apr 2, 2023 · A more objective assessment of the cardiac silhouette uses the vertebral heart size or score (VHS) measurement, with some breed conformation variations having been reported. Using the VHS method, the long axis of the cardiac silhouette is measured from the ventral border of the carina to the apex of the cardiac silhouette at its longest ...

Apr 3, 2022 · PDA L-R Vertebral heart score ( VHS) is commonly used in thoracic radiography to determine whether cardiomegaly is present. However, remember, there is a great breed-related variability. In this table you can find a table with breed-associated values. Vertebral Heart Score (VHS): Breed variations

Jun 2, 2023 · The VHS was designed to produce a standard measurement across any breed, size, or conformation of a dog, and this appears correct for the majority of dogs. However, more recent research has found some variation in certain breeds.
