Plain-English summary
A 4-year-old crossbred heavy horse was found to have unusual bone growth in its heart valves, which was causing problems with blood circulation. When examined under a microscope, the tissue showed signs of scarring, changes typical of cartilage, and mature bone, including bone marrow in parts of the heart valves. This condition is quite rare and indicates that the horse has developed bone in places where it shouldn't be, which can affect its heart function. The outcome of the treatment for this condition is not specified in the abstract.
Abstract
Ectopic bone formation in the left atrioventricular valves and cardiac fibroskeleton, with systemic circulatory disturbance, is reported in a 4-year-old crossbred heavy horse. Microscopically, there was fibrosis, chondral metaplasia and mature bone, with bone marrow within the left atrioventricular cusps and in the annuli of the aortic and right atrioventricular valves.
