Plain-English summary
A one-year-old colt was found to have a serious heart issue called aortic valve insufficiency, which means his heart wasn't working properly due to a problem with the aortic valve. He was thin and had a noticeable heart murmur, along with a strong pulse. Tests using ultrasound showed that the valve wasn't closing completely and that his heart was under extra strain. After he passed away, an examination revealed that his aortic valve was thickened and had some holes, suggesting he was born with this heart condition. Unfortunately, this colt's treatment options were limited, and he did not survive.
Abstract
Aortic insufficiency was suspected in a thin 1-year-old colt with a grade IV/V decrescendo holodiastolic murmur and a bounding arterial pulse. Echocardiographic findings (diastolic fluttering of the septal leaflet of the mitral valve, left ventricular volume overload, and incomplete aortic valve closure) were diagnostic for aortic valve insufficiency. Moderately thick fibrotic aortic valve leaflets were found at necropsy. Fenestrations were found in the aortic and pulmonic valve cusps. Congenital valvular disease may have led to aortic valvular insufficiency in this horse.
