Ten randomly chosen animals were measured by all investigators to determine interobserver reliability.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a4\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>There were 233 CT scans eligible for inclusion. Dogs weighed 2 to 96 kg (mean, 28.1 kg), with a variety of breeds represented. Golden Retrievers (n = 28) and Labrador Retrievers (n = 37) were overrepresented. The intraclass correlations were all greater than 0.9, showing excellent agreement between observers. The means and SDs of each measurement were as follows: trigone-to-trigone distance, 17.2 \u00b1 4.7 mm; the remaining circumference, 79.0 \u00b1 17.5 mm; commissure-to-commissure distance, 30.8 \u00b1 6.5 mm; septal leaflet-to-lateral leaflet distance, 26.3 \u00b1 6.0 mm; T4 length, 16.9 \u00b1 3.1 mm; and the total circumference normalized by T4, 5.7 \u00b1 0.7 mm.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a5\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>This study provides information that may help in the development of future treatment for mitral valve dysfunction and subsequent annular enlargement.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/ajvr.22.05.0085","type":"journal-article","created":{"date-parts":[[2022,10,26]],"date-time":"2022-10-26T12:31:40Z","timestamp":1666787500000},"source":"Crossref","is-referenced-by-count":1,"title":["Canine mitral valve size as measured by computed tomography"],"prefix":"10.2460","volume":"83","author":[{"given":"Wanda J.","family":"Gordon-Evans","sequence":"first","affiliation":[{"name":"Veterinary Clinical Sciences Department, Veterinary Medical Center, University of Minnesota, St. Paul, MN"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.
