Right ventricular parameters change in many cardiovascular diseases; so, the presence of normal right ventricular parameters is necessary to diagnose these diseases. Ten clinically healthy adult domestic short-haired cats including six males and four females in the range of 2.70 to 4.80 kg were studied using echocardiography without sedation. The speed and pressure of blood flow through the tricuspid and pulmonary valves, speed of the movement of tricuspid valve and tricuspid annular plane systolic excursion (TAPSE) were recorded using conventional pulsed-wave (PW) Doppler, tissue Doppler imaging (TDI) and M-mode, respectively. No significant statistical differences were observed between the measured values and sex, heart rate and body weight. A positive correlation was observed between the maximum velocity of the right ventricular outflow tract and heart rate and also between TAPSE slope and body weight. With determining the normal values of PW-TDI of the right ventricle in apparently healthy domestic short-haired cats, it is expected that with providing normal reference values, the diagnosis of heart diseases especially asymptomatic heart disease be achieved as soon as possible to provide the best appropriate therapeutic management and monitoring decision about them.
