Morphometric Assessment of Canine Heart Without Macroscopically Visible Changes Caused by Cardiac Disease

Abstract: The purpose of this study was to collect data on the cardiac morphometry of thirty adult male and female dogs without macroscopic changes indicative of heart disease, regardless of animal's body weight and score. The dogs were weighed, grouped according to their body weight, and necropsied for a macroscopic evaluation of their cardiac measurements. The data obtained were included in a database. The following cardiac measures were evaluated: vertical and horizontal axes, weight, volume, thickness of the right a… Show more

“…Heart weight is a variable associated with muscle hypertrophy and may act as a diagnostic factor for heart disease in necropsy examinations [ 18 ]. The mean cardiac weight observed corresponded to 0.95% of the body weight in dogs in G1 and 0.91% in G2, a range similar to 0.6 to 1.1% of body weight described for dogs without macroscopic features of heart disease [ 11 , 12 ], thus reinforcing the method for including normal hearts in this study.…”

“…In dogs, studies have been conducted on cardiac morphometry [ 11 , 12 ] and on the use of magnetic resonance imaging [ 13 ] and echocardiographic indices [ 14 , 15 ] to assess cardiac morphology. However, there is an insufficiency of studies that assess the normal cardiac geometry of dogs considering the basal, equatorial and apical ventricular segments and their relationships with each other and with the left atrioventricular ring.…”

“…O coração dos seres da família canidae possuem a mesma morfologia e a mesma localização em relação ao corpo que os seres da família hominidae, pois todos são mamíferos. Nos mamíferos, é anatomicamente dividido em quatro câmaras, sendo dois átrios e dois ventrículos (Queiroz et al, 2018). Apresenta aspecto ovoide, com ápice rombo e arredondado (Carvalho et al, 2002).…”

“…Uma reunião de informações acerca da morfologia cardíaca humana e canina com base nas publicações disponíveis em plataformas oficiais de pesquisa online credenciadas e reconhecidas pelos órgãos cabíveis à pesquisa e extensão tecnológica. Ghoshal (1986), Carvalho et al (2002) e Queiroz et al (2018) para suporte argumentativo na discussão morfométrica cardíaca canina e humana, Cunningham (2011) para a fisiologia cardíaca e outros autores, de igual importância para a sustentação do arquétipo argumentativo deste trabalho.…”
