Maddox is an 8 year old Shih-Poo from Chicago, IL.   Maddox was asymptomatic with severe Mitral regurgitation and moderate Tricuspid regurgitation. Six months prior to MVD diagnosis, Maddox had no heart murmur before suddenly having grade 5/6. She was prescribed Pimobendan and remained stable until surgery at JASMINE Veterinary Cardiovascular Medical Center. Her heart showed progressive enlargement during each follow-up echocardiogram leading up to surgery which later confirmed Mitral valve prolapse and ruptured chordae tendineae.  Maddox had mitral repair surgery on October 17, 2017 at the JASMINE clinic in Japan.

4 months post-surgery, Maddox has significant improvement including reduced heart size, extremely mild Mitral regurgitation, and no Tricuspid regurgitation. “Diagnostic Impressions: The evaluation demonstrates degenerative mitral valve disease with an excellent result from valve repair surgery. The disease is extremely well compensated at this time and medical therapy is not warranted.”
