Abstract
The present study was done with the objectives of generation of cardiovascular biometry and
correlating cardiovascular biometry with clinical conditions in dogs. For the generation of
cardiovascular biometry 80 healthy dogs of different breeds, age-group and gender were
subjected to thoracic radiography and biometrical parameters were recorded. The influence
of breed, radiographic view, and gender on the assessment of biometrical parameters were
evaluated. Cardiovascular biometry revealed no statistical difference between males and
females for all the parameters. VHS range in the healthy dogs was 9.1-11.5. Labrador
retrievers had the highest VHS among different breeds.VHS in RtL view was significantly
greater than LeL view in all dogs. VLAS range was 1.6-2.5 with a mean value of 1.96±0.15
in RtL and 2.06±0.18 in LeL view. VLAS in LeL was significantly higher in the RtL view.
The mean CTR was 0.54±0.03 with a range of 0.43-0.63 in healthy dogs. The mean value of
CrLA/R9, CrLV/R9, CrLV/CrLA, CdLA/R9, CdLV/R9 and CdLV/CdLA were 0.76±0.23,
0.73±0.20 ,1.02±0.16 ,0.81±0.32, 0.87±0.13 and 0.98±0.16 respectively. Short, long and
overall MHS were 2.17±0.31, 2.78±0.36 and 5.01±0.61 respectively. The regional incidence
of cardiovascular in dogs was 0.8 per cent with a higher distribution in the senile age group
and males. Labrador retriever (47%) was the most commonly affected breed with
cardiovascular disease. Left-sided cardiomegaly was the most common disorder (47%).
VHS, VLAS, CTR and MHSs were consistently measured in all the clinical cases. The
radiographic cardiovascular biometrical parameters in the dogs with cardiovascular disease
were significantly higher from the healthy dogs.
