Detect the vertebrae and heart in a thoracic right lateral radiograph; Apply the spinal measurement line across the vertebrae and the axis lines across the heart; Calculate the The authors reported that significant differences exist between the various mean values for different breeds, and suggested standardizing this technique for each breed in question. Vertebral heart score (VHS) The VHS was calculated as described previously [ 7 ], with slight modification: the short axis was placed perpendicular to the long axis so that its caudal edge terminated at the intersection point of the caudal cardiac silhouette with the ventral border of the vena cava [ 20 ]. This Paper. The mean SD (standard deviation) VHS was 10.6 0.2 vertebrae (v) in the normal dogs, which differs significantly from the mean VHS of 9.7 0.5 v in Buchanans original study with dogs of various breeds. The Vertebral Heart Score (VHS) This example: Long Axis Line (5.2) Short Axis Line (4.4) VHS for Normal Dogs = 8.7 - 10.7 VHS = L + S = 5.2 + 4.4 = 9.6 = normal Please refer to the full prescribing information on the back of this chart. Abstract 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 Buchanan and Bcheler (9.7 0.5). This study describes VHS measu A short summary of this paper. The VHS was measured using a right lateral view in twenty-eight normal dogs and fifteen dogs with myxomatous mitral valve disease. as a method to diagnose heart disease in dogs. Consider the Breed when Assessing Vertebral Heart Score Survey thoracic radiographs of 90 dogs with a history of cough and clinical and echocardiographic evidence of MVD were evaluated by 2 independent observers. DESIGN Prospective observational study. heart weight.13 This led to the vertebral scale system used to measure canine and feline heart size in radiographs, where the cardiac dimensions in the lateral projection are scaled against the thoracic vertebral column.

There were 22 female and eight male dogs. Chaudhary JK (2016) Vertebral scale system to measure heart size in thoracic radiographs of Indian Spitz, Labrador retriever and Mongrel dogs, Veterinary World, 9(4): 371-376. The VHS (vertebral heart scale) is a well-established routine in veterinary medicine (Jepsen-Grantet al. DOI: 10.1111/j.1740-8261.2012.01976.x Abstract The vertebral heart score (VHS) measurement is commonly used to provide a more objective measurement of cardiomegaly in canines. This Paper. The median value of VLAS was 1.9 and the study suggested a reference range for VLAS in healthy dogs of 1.4 to 2.2. A normal VHS range of 8.7 10.7 vertebrae was first established in the original description of the VHS method across a variety of dog breeds and chest conformations. 1 Further study has revealed that some dog breeds, particularly those that are small, brachycephalic, Jepsen-Grant K, et al. Vertebral heart scores in eight dog breeds. Use of breed-specific ranges for the vertebral heart scale Effect of left versus right recumbency on the A vertebral heart score (VHS) is a measurement used to determine if a patients heart is enlarged. A limitation of this study is that, like vertebral heart size, it is hypothesised that VLAS may vary due to breed variation. Vertebral heart score in puppies calculated by Sleeper and Buchanan reported that vertebral heart size in puppies does not change with the growth and lies within adult dogs reference range (9.70.5).

As a study of healthy dogs this investigation included no breeds of certain conformations. Journal of Veterinary Medical Science, 2009. Journal of Veterinary Medical Science, 2009. canine vertebral heart scale (continued) The vertebral heart scale: Allows estimation of cardiac size using the length of the thoracic vertebrae as the comparator on a lateral radiograph The The greatest differences were observed between VHS measured in the diastolic inspiratory phase (mean SD, 10.59 0.49 vertebral units [VU] and 10.35 0.50 VU for right and left lateral recumbency, respectively) and the systolic expiratory phase (10.11 0.37 VU and 9.92 0.50 VU for right and left lateral recumbency, respectively). Thus, similar standards exist to determine cardiac enlargement in puppies and adult dogs (Sleeper and Buchanan, 2001).

The end result is a stable measurement called the vertebral heart score It is generally unaffected by respiration and other physiologic variables Reduces radiographic overinterpretation of cardiac size Useful in assessing volume overload conditions such as valve disease or dilated cardiomyopathy Keywords: Vertebral heart Thoracic radiographs revealed right-sided enlargement of the cardiac silhouette (vertebral heart score (VHS) 11.2; reference interval = 8.9-10.1), mild main pulmonary artery (MPA) bulging, mild interstitial infiltration, and hepatomegaly.
