Abstract

Introduction/objectives: Veterinary echocardiographers' preferences for left atrial (LA) size assessment in cats have not been systematically investi-gated. The primary aim of this prospective exploratory study was to investigate echocardiographers' preferences concerning LA size assessment in cats. A second-ary aim was to investigate echocardiographers' preferences for assessing LA size in subgroups based on geographic, demographic, and professional profiles.Animals, materials, and methods: An online survey instrument was designed, ver-ified, and distributed globally to veterinary echocardiographers.Results: A total of 655 veterinary echocardiographers from six continents and 54 countries, working in specialty practice (56%) and in general practice (38%), pro-vided data. Linear two-dimensional (2D) technique was favored by most echocar-diographers (n = 612) for LA size assessment. Most commonly, respondents combined linear 2D with subjective assessment (n = 227), while 209 used linear 2D-based methods alone. Most echocardiographers using linear 2D-based methods preferred the right parasternal short-axis view and to index the LA to the aorta (Ao). Approximately 10% of the respondents obtained LA dimensions from a right parasternal long-axis four-chamber view. Approximately one-third of echocardio-graphers that made linear measurements from 2D echocardiograms shared the same preferences regarding cat position, acquisition view, indexing method and time point identification for the LA measurement. The responses were comparably homogeneous across geographic location, level of training, years performing echo-cardiography, and type of practice.Discussion/conclusion: Most veterinary echocardiographers assessed LA size in cats using linear 2D echocardiography from a right parasternal short-axis view, and in-dexed LA to Ao. Respondents' preferences were similar over geographic, demo-graphic, and professional backgrounds. 2023 The Authors. Published by Elsevier B.V.
