Transthoracic echocardiography in healthy Diannan small-ear pigs.

ABSTRACT:

Background

Pigs are widely used as large animal models in cardiovascular research. Establishing breed-specific physiological reference values is essential for experimental design and data interpretation.

Method

Cardiac chamber dimensions, great vessel diameters, and hemodynamic parameters were systematically evaluated by transthoracic echocardiography (TTE) in 31 healthy Diannan small-ear pigs (mean weight: 47.2 ± 17.2 kg; 15 males, 16 females). Key structural indices were compared with human reference values. Animals were divided into three weight groups: 20-39 kg, 40-59 kg, and 60-80 kg.

Results

Left and right atrial and ventricular diameters and volumes, as well as aortic and pulmonary artery diameters, increased significantly with body weight (P < 0.05) but remain
