Our previous work using intramyocardial radiofrequency ablation for hypertrophic obstructive cardiomyopathy (Liwen procedure) may provide another approach to obtain the myocardial samples.<h4>Method</h4>Seventeen patients with HOCM were enrolled for biopsies through percutaneously accessed intramyocardial septum and evaluated possible complications.<h4>Results</h4>We obtained 31 specimens from 17 patients with a success rate of sample acquisition 100.0%.
