Plain-English summary
A 9-week-old Weimaraner puppy was showing signs of heart failure, which means it was likely having trouble breathing and might have been lethargic. Unfortunately, after the puppy passed away, a thorough examination revealed a serious heart condition called congenital endocardial fibroelastosis, where the heart's inner lining becomes thickened and less effective. This condition can lead to severe heart problems and is often not treatable. Sadly, the puppy did not recover due to the severity of the heart issues.

Abstract
A 9-week-old Weimaraner was tentatively diagnosed clinically with congenital left-sided heart failure. On necropsy, diffuse fibroplasia over the left ventricular endocardium; small, deformed papillary muscles; and pulmonary congestion were evident. Microscopically, the fibroplasia extended into the myocardium and cardiomyocytes, and Purkinje fibers were degenerated, consistent with congenital endocardial fibroelastosis.
