“…Once the possibility of pulmonary oedema has been recognised, appropriate treatment can be started and followed up with more specific diagnostic tests when the patient is in a more stable condition. The labile nature of pulmonary oedema facilitates relatively rapid retrospective diagnosis if a marked reduction in lesion severity is observed in repeat radiographs obtained after 12 to 24 hours diuresis and cage rest (Lord and others 1974, Lord and Zontine 1977, Lamb 2002).…”

“…Increased left atrial size was diagnosed from right lateral images as unequivocal bulging of the dilated left atrium extending caudo‐dorsally. Pure dorsal ventral elongation of the cardiac silhouette without caudal dorsal bulging was not considered specific of left atrial enlargement . On ventrodorsal radiographs, increased size of the left atrium and the left auricular appendage was diagnosed as bulging of the left heart border visible at the 1:30 o'clock to 3 o'clock position, using the clock‐face analogy .…”

The aims of this study were to evaluate left atrial size in cats with acute left-sided congestive heart failure. We hypothesized that left atrial size as determined by thoracic radiography can be normal in cats with acute left-sided congestive heart failure. One hundred cats with acute left-sided congestive heart failure in which thoracic radiography and echocardiography were performed within 12 h were identified. Left atrial size was evaluated using right lateral and ventrodorsal radiographs. Measurements were compared to two-dimensional echocardiographic variables of left atrial size and left ventricular size. On echocardiography, left atrial enlargement was observed in 96% cats (subjective assessment) whereas maximum left atrial dimension was increased (>15.7 mm) in 93% cats. On radiographs left atrial enlargement (subjective assessment) was found in 48% (lateral view), 53% (ventrodorsal view), and 64% (any view) of cats whereas left atrial enlargement was absent in 36% of cats in both views. Agreement between both methods of left atrial size estimation was poor (Cohen's kappa 0.17). Receiver operating characteristic curve analysis identified a maximum echocardiographic left atrial dimension of approximately 20 mm as the best compromise (Youden index) between sensitivity and specificity in the prediction of radiographic left atrial enlargement. Left atrial enlargement as assessed by thoracic radiography may be absent in a clinically relevant number of cats with congestive heart failure. Therefore, normal left atrial size on thoracic radiographs does not rule out presence of left-sided congestive heart failure in cats with clinical signs of respiratory distress.

“…Radiographic abnormalities of the cardiac silhouette, however, are only detected if normal parameters are known and, to this end, abundant studies related to the radiographic assessment of the cardiac size have been performed in several species, including cats (Lord & Zontine 1977, Litster & Buchanan 2000a, Litster & Buchanan 2000b, Ghadiri et al 2008, dogs (Lehmkuhl et al 1997, Lamb et al 2001, Bavegems et al 2005, Hansson et al 2005, Marin et al 2007, Spasojević-Kosić et al 2007, Kraetschmer et al 2008, ferrets (Stepien et al 1999), llamas (Mattoon et al 2001), psittacines (Straub et al 2002), cattle (Jilintai et al 2006), monkeys (Harada et al 2009), rabbits (Onuma et al 2010) and alpacas (Nelson et al 2011).…”

RESUMO.-[Mensurações radiográficas relacionadas às dimensões cardíacas em borregas Bergamácia.]No exame radiográfico torácico, rotineiramente utilizado em casos em que a avaliação cardíaca é indicada, a análise quantitativa do coração é um recurso útil a ser usado em combinação com a avaliação subjetiva. Diversos estudos relacionados à análise objetiva do tamanho cardíaco têm sido realizados em várias espécies, incluindo ovinos; no entanto, há pouca informação sobre os parâmetros cardíacos de ovinos jovens da raça Bergamácia. Dessa for-ABSTRACT.-Babicsak V.R., Alves L.S., Tsunemi M.H. & Vulcano L.C. 2017. Radiographic measurements related with the cardiac size in young female Bergamasca sheep. Pesquisa Veterinária Brasileira 37 (12):1526-1530. In thoracic radiographic examination, routinely used in cases which cardiac evaluation is indicated, quantitative assessment of the heart is a useful role to be used in combination with subjective analysis. Numerous studies about objective assessment of the cardiac size have been performed in several species, including sheep; however, there is scarce information regarding cardiac parameters of young Bergamasca sheep. Therefore, the purpose of this study was to determine the average results and suggest the range of expected normal values for parameters related to the heart size of young female Bergamasca sheep by radiographic evaluation. Fifteen healty 8 months-old female Bergamasca sheep (mean weight: 41.13±4.71kg) were submitted to right lateral recumbency thoracic radiography. The length of the fourth and third to fifth thoracic vertebrae, cardiac height and width, vertebral heart size, cardiophrenic contact, caudal vena cava height, aorta caliber and tracheal angle were measured and the mean results found were, respectively: 2.46±0.11cm (95% CI 2., 1.88±0.19cm (95% CI 1.79-1.97), 2.05±0.11cm (95% CI 2.00-2.11) and 14.36±2.73° (95% CI 12.98-15.75). Cardiac height and width and the sum of these parameters were compared to the length of third to fifth thoracic vertebrae, resulting in the respective mean values: 1.84±0.08 (95% IC 1.80-1.88), 1.20±0.05 (1.17-1.22) and 3.04±0.11 (95% IC 2.98-3.09). Ratios of cardiophrenic contact to cardiac height and caudal vena cava height to length of fourth thoracic vertebra were also evaluated and the mean values obtained were 0.33±0.05 (95% IC 0.30-0.35) and 0.76±0.08 (95% IC 0.72-0.81), respectively. Authors suggest that the values available in this study may be used as reference for normal heart size in young female Bergamasca sheep and as basis for further studies.
