Original publication title: An interventricular septal defect, pulmonary stenosis and bicuspid pulmonary valve in a Welsh pony foal.

Plain-English summary
A 6-month-old Welsh pony filly was found to have a heart defect called an interventricular septal defect, along with a narrowing of the pulmonary artery (pulmonary stenosis) caused by a heart valve that has two flaps instead of the usual three (bicuspid pulmonary valve). She showed signs of not being able to exercise well, had a loud heart murmur, and a noticeable vibration over her chest. Tests done during a procedure to look at her heart confirmed the problem, but unfortunately, the diagnosis was only confirmed after she passed away.
Abstract
A 6 month Welsh pony filly with an interventricular septal defect in conjunction with a pulmonary stenosis due to a bicuspid pulmonary valve is described. The animal had poor exercise tolerance, a loud pansystolic murmur and a precordial thrill. Blood pressure and oxygen tension values obtained during cardiac catheterization suggested the diagnosis which was confirmed at autopsy.
