UNASSIGNED: 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.
UNASSIGNED: The MVP method with ACR employed demonstrated better durability and promoted longer survival than that of previous dog mitral valve replacements.
■一个5个月大的女性杰克·罗素,体重3.5公斤,表现为呼吸困难和兴奋时崩溃。由于腱索破裂而导致肺水肿的急性MR被诊断为疑似先天性二尖瓣异常。尽管用大剂量药物治疗,心力衰竭症状和扩大恶化。使用聚四氟乙烯缝合线插入人工腱索置换(ACR),并进行了瓣环成形术。狗在术后第7天出院。七年后,这只狗接受了前十字韧带完全撕裂的手术,没有心脏体征。11.5年后,这只狗没有心脏问题,死于非心脏疾病。
■使用ACR的MVP方法显示出比以前的狗二尖瓣置换术更好的耐久性并促进更长的生存期。
