Plain-English summary
A 7-year-old male domestic shorthair cat was diagnosed with hypertrophic cardiomyopathy (HCM), a condition where the heart muscle thickens, and suspected mitral stenosis (MS), which is a narrowing of the heart valve. The diagnosis was confirmed through various tests, including an electrocardiogram and ultrasound of the heart. Unfortunately, the cat passed away, and a post-mortem examination showed severe changes in the heart, indicating that the mitral valve was significantly affected by the HCM. This case highlights that cats with HCM can develop additional heart problems like mitral stenosis.

Abstract
A seven-year-old castrated male domestic shorthair cat was diagnosed with hypertrophic cardiomyopathy (HCM) and suspected mitral stenosis (MS) based on electrocardiography, thoracic radiographs and echocardiographic findings. Post-mortem examination of the heart revealed morphological features consistent with HCM. In addition, there was marked fibrous deposition on the surfaces of the chordae tendineae extending to both mitral valve leaflets, which caused total chordal fusion into pillars of fibrous tissue and fusion of the commissures. The present case indicates that acquired MS can occur in association with HCM in the cat.
