Description
Hyo-Seung Nam and Yein Oh report a 2026 case of odd heart change in a small dog with valve disease. The dog had a leaky mitral valve and later excess adrenal hormone output. That hormone excess usually worsens heart strain, so improvement was a surprise.
The patient was a 10-year-old spayed female Maltese with breathing trouble. Early scans showed a large heart and left-sided heart failure from valve leak. Nineteen months later, adrenal disease was found and heart size had shrunk. Wall thickening may have reshaped the valve and cut the leak in this case. Heart drugs were reduced, and care with two drugs kept the dog stable afterward.
