Bovine tricuspid endocarditis as a cause of increased serum concentration of cardiac troponins.

Abstract

A Holstein cow presented for weight loss and anorexia had tachycardia, heart murmur, and a chronic inflammatory process. Serum cardiac troponin I was increased at 3.52 ng/mL. Transthoracic echocardiography revealed a thickened tricuspid valve and comet-tail artifacts compatible with gas in the affected area. This report suggests that serum cardiac troponin I may be increased in bacterial endocarditis in cattle.
