Plain-English summary

Two 2-month-old kittens were brought to the vet because they had a loud heart murmur. One of the kittens was struggling to breathe and had trouble exercising. Tests showed that they had a serious heart condition called hypertrophic cardiomyopathy, which caused their hearts to thicken and obstruct blood flow. Unfortunately, both kittens passed away at 5 and 12 months old due to this condition.

Abstract

Two 2-month-old kittens presented with a loud cardiac murmur. One cat showed severe signs of heart failure such as respiratory effort and exercise intolerance. Echocardiography revealed left ventricular concentric hypertrophy and severe left ventricular outflow obstruction. They died at 5 and 12 months of age, respectively. Necropsy and histopathology confirmed hypertrophic cardiomyopathy.
