Hypertrophic Cardiomyopathy Attributable to Mitochondrial DNA Mutation Diagnosed by Pathology and Gene Sequencing.

The article presents a case study of a 46-year-old man with exertional dyspnea and a 10-year history of hearing impairment. Medical imaging examinations revealed severe concentric left ventricular hypertrophy with a diffused speckled pattern of the myocardium, hypertrophy of cardiomyocytes, and hyperplasia of mitochondria. The patient was diagnosed with hypertrophic cadiomyopathy attributable to mitochondrial DNA mutation through pathology and gene sequencing.
