A 3-month-old female West Highland white terrier (case 1) who had a cardiac murmur and mild dyspnea and a 3-month-old male Yorkshire terrier (case 2) who had a cardiac murmur were presented at Azabu University Teaching Hospital and examined because of cardiac diseases. Utilizing physical examination, X-ray, electrocardiogram (ECG) and echocardiogram in the first visit, case 1 was diagnosed as pulmonary arteriostenosis (PS) and case 2 was diagnosed as aortic stenosis. We followed up case 1 for 21 months and case 2 for 15 months.
Case 1 gradually became cyanotic after exercise at 16 months of age and case 2 showed no clinical abnormality. In the X-ray examination, neither case showed any changes. In the ECG, right ventricular enlargement in case 1 and left ventricular enlargement in case 2 were observed, each case being stable. In the echo examination, each case had normal left ventricular function.
Case 1 is still alive, however, case 2 died suddenly.
