Abstract:
Cavalier King Charles Spaniels (CKCS) are predisposed to developing myxomatous mitral valve disease (MMVD), with radiographs frequently used to screen for evidence of left-sided cardiomegaly secondary to MMVD. Vertebral heart size (VHS), vertebral left atrial size (VLAS), modified VLAS (M-VLAS), and radiographic left atrial dimension (RLAD) are reported as objective measurements of global heart size and left atrial size. Normal VHS in CKCS (10.6 +/- 0.5) is reportedly higher than the non-breed-specific value (9.7 +/- 0.5). Breed-specific VLAS, M-VLAS, and RLAD cut-offs have not been reported in CKCS. The aim of this prospective reference interval study was to describe the VHS, VLAS, M-VLAS, and RLAD values for 30 clinically healthy adult CKCS. Inclusion criteria were unremarkable physical examination, normal echocardiography, and thoracic radiographs without malposition/abnormalities. There were 22 female and eight male dogs. Ages ranged from 1 to 6 years. The VHS mean value in our sample was 10.08 +/- 0.56 (95% range, 9.87-10.29). This was significantly greater than a previously published general canine reference value of 9.7 +/- 0.5 and significantly less than a previously published CKCS breed-specific value of 10.6 +/- 0.5 (P < 0.01). Mean VLAS, M-VLAS, and the RLAD values in our study were 1.79 +/- 0.3 (95% range, 1.68-1.9), 2.23 +/- 0.44 (95% range, 2.06-2.39), and 1.2 +/- 0.34 (95% range, 1.07-1.33), respectively. These were significantly less than previously published reference interval values (P < 0.001). The VHS, M-VLAS, and the RLAD were not affected by sex, body weight, or BCS; whereas the VLAS was moderately affected by body weight. Findings from this study can be used as background for future thoracic radiographic assessments in CKCS.
