Trans-Septal Myocardial Biopsy in Hypertrophic Cardiomyopathy Using the Liwen Procedure: An Introduction of a Novel Technique.

ABSTRACT:

Objective

The purpose of this study was to evaluate the feasibility and safety of myocardial biopsy using a new approach, the Liwen procedure.

Background

Myocardial biopsy is essential when other methods could not differentiate other etiologies from hypertrophic obstructive cardiomyopathy (HOCM). Our previous work using intramyocardial radiofrequency ablation for hypertrophic obstructive cardiomyopathy (Liwen procedure) may provide another approach to obtain the myocardial samples.

Method

Seventeen patients with HOCM were enrolled for biopsies through percutaneously accessed intramyocardial septum and evaluated possible complications.

Results

We obtained 31 specimens from 17 patients with a success rate of sample acquisition 100.0%. The number of myocardial sam
