Abstract

A2-year-old cachectic cross-breed gelding was admitted to
Veterinary Teaching Hospital of University of Tehran following
the onset of a marked respiratory distress, coughing and ventral
edema. Clinical examinations indicated harsh respiratory and
expiratory sounds as well as jugular vein distention. The
respiratory and heart rates were 35/min and 60 bpm, respectively.
Agrade III/IV pansystolic murmur with the PMI on the tricuspid
valve, which could be heard on the left side, was detected. Sinus
tachycardia was revealed by electrocardiography. Rupture of the
chorda tendineae of the tricuspid valve, pulmonary artery
regurgitation, pulmonary artery hypertension, tricuspid valve
regurgitation, pulmonary artery, and right ventricular dilation
were also found in echocardiography. These findings were
confirmed at post mortem examinations. On the basis of the
findings, chorda tendineae rapture of the tricuspid valve and
right side heart failure due to primary pulmonary hypertension
were diagnosed.
