“…Additionally, abnormalities of the tricuspid valve similar as to what observed in the presented case were observed in cats, where a large leaflet of the valve was more prominent [7]. Dogs were reported mainly with incomplete AVCD and, strikingly, in much lesser proportion than cats [2][3][4][10][11][12][13][14]. In horses, only complete AVCD cases were described [15][16][17][18].…”

“…A diagnosis of AVCD is performed based on cardiovascular examination using imaging methods like radiography, ECG, and echocardiography. Generally, radiography reveals cardiomegaly, especially regarding the right atrium, both ventricles, and a pronounced pulmonary artery [4,14]. The ECG commonly shows QRS changes compatible with conduction abnormalities, especially bundle branch blocks [3].…”

“…An AVCD may be partial (incomplete), transient or intermediate, transitional or complete. The difference between them also reflects the severity of the defect [1][2][3][4]. The complete variety results from concurrent large ASD and VSD (i.e.…”

“…In veterinary medicine, AVCD has been described in several species: eight pigs [5], 31 cats [1,[6][7][8][9], nine dogs [2][3][4][10][11][12][13][14], and four horses [15][16][17][18]. Factors like oxygen deficiency, viral infection during early pregnancy, nutritional, genetic, and teratogenic factors have been suggested as possible factors triggering the development of this condition and possibly other congenital heart diseases [14,18].…”

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. Case presentation 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.

“…Endocardial cushion defects have been reported in both cats and dogs [126,[134][135][136], without any apparent breed or sex predisposition. In our experience, this disease is more frequently seen in cats than in dogs.…”
