Cardiovascular images: parachute mitral valve in a cat.

Parachute mitral valve is a rare congenital anomaly in cats, often associated with other congenital heart defects.

A six-month-old intact female domestic shorthair cat was presented to the Ohio State University Veterinary Medical Center for evaluation of a heart murmur. Echocardiography revealed a large, left-to-right shunting ventricular septal defect (VSD), severe left heart volume overload, increased pulmonary artery flow, tricuspid regurgitation, mild mitral regurgitation, and left-sided congestive heart failure. Suspected conditions included relative pulmonary stenosis, pulmonary hypertension, and a mitral valve malformation. Due to the cat's fractious nature, further echocardiographic characterization was deferred. A month later, the cat underwent pulmonary artery banding as palliative treatment for the VSD. Subsequent echocardiograms, performed four weeks and three months later, identified mitral valve dysplasia with a parachute mitral valve. Parachute mitral valve is a rare congenital anomaly characterized by unifocal attachment of the chordae tendineae of both leaflets to a single papillary muscle, often associated with other congenital heart defects.
