背景:房室道缺损是一种罕见的先天性心脏疾病,描述了房间隔缺损的存在,室间隔改变的可变表现,包括二尖瓣和三尖瓣的室间隔缺损畸形。这种缺陷已经在人类中描述过,狗,猫,猪,和马。
方法:本文描述了一个四岁完整的雄性宠物雪貂(Mustelaputoriusfuro)的完全房室管缺损的情况,这是由于后部无力而出现的,共济失调,食欲下降。巨大的收缩期杂音,呼吸困难,在临床检查中检测到后肢轻瘫。胸片显示全身心脏肿大和肺水肿。心电图显示窦性心律,P波和QRS波延长。超声心动图显示巨大的房间隔缺损,房室发育不良,室间隔缺损.氧气姑息治疗,呋塞米,螺内酯,依那普利,地尔硫卓,选择支持治疗作为首选疗法。雪貂在住院期间逐渐恢复。在三个月和六个月的随访检查显示心脏功能稳定。
结论:据作者所知,这是首次在宠物雪貂中描述房室道缺损。
BACKGROUND: Atrioventricular canal defect is a rare congenital disorder of the heart and describes the presence of an atrial septal defect, a variable presentation of ventricular septal alterations including ventricular septal defect malformations in the mitral and tricuspid valves. The defect has been described in human beings, dogs, cats, pigs, and horses.
METHODS: This paper describes the
case of a complete atrioventricular canal defect in a four-year-old intact male pet ferret (Mustela putorius furo), which was presented due to posterior weakness, ataxia, and decreased appetite. A loud systolic murmur, dyspnea, and hind limb paraparesis were detected during the clinical examination. Thoracic radiographs showed generalized cardiomegaly and lung edema. ECG showed sinus rhythm with prolonged P waves and QRS complexes. Echocardiography showed a large atrial septal defect, atrioventricular dysplasia, and a ventricular septal defect. Palliative treatment with oxygen, furosemide, spironolactone, enalapril, diltiazem, and supportive care was chosen as the therapy of choice. The ferret recovered gradually during hospitalization. A follow-up examination at three and six months showed stabilization of cardiac function.
CONCLUSIONS: To the authors knowledge, this is the first time an atrioventricular canal defect has been described in a pet ferret.
