Redo mitral valve repair under repeat cardiopulmonary bypass in a dog.
Objective: To report the lifelong outcome of a redo mitral valve repair performed under repeat cardiopulmonary bypass (CPB) in a dog.
Study design: Case report.
Animal: An 11-year-old, 4.0-kg neutered male Chihuahua, previously treated with surgical mitral valve repair for myxomatous mitral valve disease at the age of eight, presented with recurrent left heart failure caused by worsening residual mitral regurgitation (MR) following the initial repair.
Methods: Redo mitral valve repair was performed 2 years and 7 months after the initial surgery. The procedure, conducted under hypothermic CPB, involved adding and adjusting eight artificial chordae to align with the reconstructed mitral annular plane.
Results: The redo surgery successfully reduced MR, improved cardiac function, and resulted in more than 5 years of survival without MR recurrence.
Conclusion: This case demonstrates the feasibility of redo mitral valve repair in managing recurrent MR in dogs, highlighting its potential to improve long-term outcomes in veterinary surgery and cardiology.
期刊介绍：
Veterinary Surgery, the official publication of the American College of Veterinary Surgeons and European College of Veterinary Surgeons, is a source of up-to-date coverage of surgical and anesthetic management of animals, addressing significant problems in veterinary surgery with relevant case histories and observations.
It contains original, peer-reviewed articles that cover developments in veterinary surgery, and presents the most current review of the field, with timely articles on surgical techniques, diagnostic aims, care of infections, and advances in knowledge of metabolism as it affects the surgical patient. The journal places new developments in perspective, encompassing new concepts and peer commentary to help better understand and evaluate the surgical patient.
