Endomyocardial biopsy may enable antemortem diagnosis in refractory infantile tachycardia; single-case data leave broader utility open.
Yutani et al. (1985) conducted a case report in Infantile cardiomyopathy (n=1). Right endomyocardial biopsy was evaluated on Diagnosis of mitochondrial cardiomyopathy. Right endomyocardial biopsy provided light and electron microscopical proof of infantile mitochondrial cardiomyopathy in a 16-month-old girl with drug-resistant tachycardia.
