Abstract

|
A 1.3 year-old Castrated male Bedlington terrier (10.0 kg of body weight) was presented with heart murmur and occasional coughing. Diagnostic imaging studies revealed supravalvular pulmonic stenosis (maximal velocity 2.91 m/s) from abnormal membranous structure (aperture) distal to the pulmonary valve in the main pulmonary artery. Further study also revealed pulmonic regurgitant (1.82 m/s of peak velocity, 13.2 mmHg of pressure gradient) jets started from the abnormal membranous structure. Since the dog had no obvious clinical signs related to heart failure, no interventional therapy including balloon dilation was considered in this case. Instead, medical treatment for preventing further deterioration of clinical signs related to PS was done with enalapril. This case report described a rare case of type III supravalvular PS in a dog, which has never been reported. Further deterioration of clinical signs has yet been recognized after medical treatment.
