Ecocardiografia de cães da raça Yorkshire Terrier clinicamente normais

Abstract

RESUMODeterminaram-se os parâmetros ecocardiográficos em modo-M normais de cães da raça Yorkshire Terrier. Foram utilizados 30 cães clinicamente sadios, com peso médio de 2,420,64kg e idades entre um e seis anos. O diâmetro do átrio esquerdo e da aorta, a dimensão interna do ventrículo esquerdo na diástole e na sístole, a espessura do septo interventricular na diástole e na sístole, e a espessura da parede posterior do ventrículo esquerdo na diástole e na sístole correlacionaram-se com o peso corporal. As demais variáveis do modo-M não se correlacionaram com peso corporal, sexo ou idade. Os valores ecocardiográficos obtidos neste estudo podem ser utilizados como referência para cães dessa raça.Palavras-chave: cão, ecocardiografia, modo-M, coração ABSTRACT The aim of this study was to establish the normal echocardiographic parameters in M-mode for Yorkshire Terrier dogs. Thirty clinically normal dogs with mean weight of 2.420.64kg and ages varying from one to six years old were studied. The left atrial diameter, the aortic diameter, the left ventricular internal dimension at end-diastole and end-systole, end-diastolic and end-systolic interventricular septal thickness, and end-diastolic

“…In recent years many breed specific echocardiographic parameters have been published for canines (Crippa et al 1992, Morrison et al 1992, Vollmar 1999 Guglielmini et al 2006, Kayar et al 2006, Muzzi et al 2006, Bavagems et al 2007, Cunningham et al 2009, Vörös et al 2009, Castro et al 2011, Jacobson et al 2013, Gugjoo et al 2014 showing significant differences between these measurements in different dog breeds (Boon 2011b). This underlines the necessity to prepare reference values for specific breeds, especially ones having different chest conformations (Morrison et al 1992, Della Torre et al 2000, Boon 2011b) or athletic ability (Jacobson et al 2013).…”

“…Although generic reference values for echocardiographic measurements have been published for dogs (Crippa et al 1992, Vollmar 1999, Cornell et al 2004, Kayar et al 2006, Muzzi et al 2006, Bavegems et al 2007, Cunningham et al 2008, Boon 2011b, Castro et al 2011, Jacobson et al 2013, Gugjoo et al 2014, recent years have shown that recorded values for specific dog breeds must be interpreted in light of their own normal values. The Dachshund is one of the more frequent small animal patients predisposed to heart disease, specifically chronic mitral valve disease (CMVD) (Kittleson 1998).The aim of this study was to compare basic echocardiographic measurements between Dachshunds and other breeds, and, if these proved significantly different, to establish separate reference intervals for echocardiographic measurements in Dachshunds.…”
