Right ventricular structural and functional changes result from many cardiovascular disorders in cats. Accordingly, echocardiographic evaluation of the size and function of the right ventricle (RV) provides important prognostic information in many conditions affecting the right heart. Therefore, detection of these changes is clinically important and needs reference values to ease the diagnosis. The present study was designed to calculate structural and functional right ventricular variables in 10 apparently healthy cats (six males and four females, average age 1 year old and body weight 2.70 - 4.80 kg) with no sedation. For this purpose, The minimum, maximum, mean ± standard error of the mean of right ventricle internal dimension in systole and diastole (cm), right ventricle free wall thickness in systole and diastole (cm), fractional shortening (%), right ventricle volume in systole and diastole (mL), right ventricle area in systole and diastole (cm), ejection fraction (%) and fractional area change (%) were measured and reported. Descriptive statistics were provided for all calculated variables. Statistical correlation of the collected variables with body weight, gender and heart rate were analyzed. Results showed that there is a significant correlation between heart rate with body weight and between systolic and diastolic RV volumes with gender. The results of the present study would help clinicians in the diagnosis of the right heart changes in DSH cats.
右心室结构和功能的改变源于猫的多种心血管疾病。因此，超声心动图评估右心室（RV）的大小和功能，在许多影响右心的疾病中可提供重要的预后信息。所以，检测这些变化在临床上很重要，且需要参考值以辅助诊断。本研究旨在计算10只未使用镇静剂的健康猫（6只雄性和4只雌性，平均年龄1岁，体重2.70 - 4.80 kg）的右心室结构和功能变量。为此，测量并报告了收缩期和舒张期右心室内径（cm）、收缩期和舒张期右心室游离壁厚度（cm）、缩短分数（%）、收缩期和舒张期右心室容积（mL）、收缩期和舒张期右心室面积（cm）、射血分数（%）以及面积变化分数（%）的最小值、最大值、平均值±平均标准误差。对所有计算变量进行了描述性统计。分析了所收集变量与体重、性别和心率之间的统计相关性。结果表明，心率与体重之间以及收缩期和舒张期右心室容积与性别之间存在显著相关性。本研究结果将有助于临床医生诊断DSH猫的右心变化。
