Does right ventricular endomyocardial biopsy reveal occult myocardial disease in patients with spontaneous ventricular tachycardia but no apparent structural heart disease?
Right ventricular endomyocardial biopsy reveals occult primary myocardial abnormalities in nearly 90% of patients presenting with serious ventricular arrhythmias and apparently normal hearts.
Strain et al. (1983) conducted an observational in Spontaneous ventricular tachycardia or fibrillation without apparent structural heart disease (n=18). Right ventricular endomyocardial biopsy was evaluated on Abnormal right ventricular endomyocardial biopsy specimens. Right ventricular endomyocardial biopsy revealed occult myocardial abnormalities in 89% (16 of 18) of patients with spontaneous ventricular tachycardia but no apparent structural heart disease.
