| Abstract: | Case 1 involved a 4-month-old intact male Somali cat in which peripheral pulmonary arterystenosis (PPS) was recognized after a cardiac murmur remained following patent ductusarteriosus ligation. Case 2, which involved a 1-year-old neutered male Norwegian Forestcat, and Case 3, which involved a 6-month-old intact female American Curl cat, werereferred, because of cardiac murmurs. Grades III to IV/VI systolic heart murmurs wereauscultated at the left heart base in all 3 cats. All cases showed bilateral pulmonaryartery stenosis, although there were no associated clinical signs. In Cases 1 and 2, thepressure gradient through the stenosis decreased after treatment with atenolol. |
