Plain-English summary
A 12-year-old spayed Corgi was brought in for heart failure that wasn't getting better with standard medications. After a heart ultrasound showed thickening of the heart muscle, the vet diagnosed her with primary hypertrophic cardiomyopathy, a condition where the heart muscle becomes abnormally thick. The vet started her on a new medication called diltiazem, which helped improve her condition for several weeks. This case highlights the importance of thorough heart evaluations to find the right treatment for dogs with heart issues.

Abstract
A 12-year-old spayed Corgi with heart failure did not respond to conventional medical therapy for congestive cardiomyopathy (furosemide, 2.5 mg/kg of body weight, IV, q 8 h; captopril 1 mg/kg, PO, q 8 h). Cardiac ultrasonography subsequently revealed a hypertrophic left ventricle and interventricular septum. Because a causative agent could not be identified, a diagnosis of primary hypertrophic cardiomyopathy was made. Administration of diltiazem (1.25 mg/kg, PO, q 12 h) resulted in sustained clinical improvement for several weeks. Complete cardiac evaluation, including echocardiography, was essential in determining the correct treatment for this dog.
