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.

摘要

目的

报告第二例因二尖瓣发育不良导致急性二尖瓣反流（MR）的二尖瓣成形术（MVP）年轻小型犬病例。

病例描述

一只 5 月龄母杰克罗素梗，体重 3.5kg，兴奋时出现呼吸困难和虚脱。由于腱索断裂，诊断为急性 MR 合并肺水肿，疑似先天性二尖瓣异常。尽管给予大剂量药物治疗，但心力衰竭症状和心脏扩大仍恶化。使用聚四氟乙烯缝线插入人工腱索置换（ACR），并进行瓣环成形术。术后第 7 天出院。7 年后，该犬因完全前十字韧带撕裂而接受手术，无心脏体征。11.5 年后，该犬无心脏问题，并死于非心脏疾病。

结论

与之前的狗二尖瓣置换术相比，ACR 辅助的 MVP 方法具有更好的耐久性，可促进更长的生存时间。
