Plain-English summary
A 5-month-old female Jack Russell was brought in for breathing problems and fainting after excitement. She was diagnosed with severe heart issues caused by a congenital defect in her mitral valve, which had ruptured chords. After initial treatments failed, the vet performed surgery to replace the damaged parts of the valve. Remarkably, the dog recovered well and lived for over 11 years without any further heart problems, passing away from an unrelated illness.

Abstract
UNLABELLED: : We aimed to report the second case of mitral valve plasty (MVP) for acute mitral regurgitation (MR) due to mitral valve dysplasia in a young small dog. CASE DESCRIPTION: A 5-month-old female Jack Russell, weighing 3.5 kg, presented with dyspnea and collapse upon excitation. Acute MR with pulmonary edema due to chordal rupture was diagnosed with a suspected congenital mitral valve anomaly. Despite treatment with high-dose drugs, heart failure symptoms and enlargement worsened. An artificial chordal replacement (ACR) was inserted using polytetrafluoroethylene sutures, and annuloplasty was performed. The dog was discharged on postoperative day 7. After 7 years, the dog underwent operations for complete anterior cruciate ligament tears with no cardiac signs. After 11.5 years, the dog showed no cardiac issues and died from a non-cardiac disease. CONCLUSION: The MVP method with ACR employed demonstrated better durability and promoted longer survival than that of previous dog mitral valve replacements.
