INTRODUCTION
Older small breed dogs are considered at risk for heart failure secondary to chronic mitral valve disease. However, few data are available on the onset of this disease in such dogs. This study was performed to determine if auscultation alone can be used to eliminate clinically relevant mitral valve regurgitation seen in echocardiography in Dachshund dogs.
MATERIAL AND METHODS
Clinical and echocardiographic data were obtained from 107 dogs without heart murmurs.
RESULTS
The study revealed that 63.6% of the dogs had mitral regurgitation. Numbers increased with age and a larger percentage of male Dachshunds were affected than female Dachshunds. Mitral valve prolapse and thickening were mild, and the regurgitant area inextensive in most dogs.
CONCLUSIONS
The study shows that mitral valve regurgitation is prevalent (63.6%) in Dachshunds without heart murmurs. Typical lesions often become apparent during echocardiographic examinations in dogs under 5 years of age.
引言
老年小型犬被认为有继发于慢性二尖瓣疾病的心力衰竭风险。然而，关于此类犬只该疾病发病情况的数据很少。本研究旨在确定仅通过听诊是否可用于排除腊肠犬超声心动图检查中所见的具有临床意义的二尖瓣反流。
材料与方法
从107只无心脏杂音的犬只获取临床和超声心动图数据。
结果
研究显示63.6%的犬患有二尖瓣反流。数量随年龄增加，受影响的雄性腊肠犬比例高于雌性腊肠犬。大多数犬的二尖瓣脱垂和增厚程度较轻，反流面积不大。
结论
该研究表明，无心脏杂音的腊肠犬中二尖瓣反流很普遍（63.6%）。典型病变常在5岁以下犬的超声心动图检查中显现。
