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.
一匹1岁的瘦小马驹，有IV/V级递减型全舒张期杂音和洪脉，怀疑有主动脉瓣关闭不全。超声心动图检查结果（二尖瓣隔叶舒张期扑动、左心室容量超负荷和主动脉瓣关闭不全）可诊断为主动脉瓣关闭不全。尸检发现主动脉瓣叶中度增厚且纤维化。在主动脉瓣和肺动脉瓣瓣尖发现有小孔。先天性瓣膜疾病可能导致了这匹马的主动脉瓣关闭不全。
