Two-dimensional echocardiographic guiding of endomyocardial biopsy

L Pierard, D El Allaf, V D'Orio, JC Demoulin and J Carlier

Two-dimensional echocardiography provides adequate spatial orientation and anatomic definition. Eighteen consecutive patients undergoing myocardial biopsy had concomitant two-dimensional echocardiography during 22 biopsies of five to six samples each. The transducer was placed at the apex and in the subcostal area and four-chamber views were used. The bioptome was seen entering the right atrium and crossing the tricuspid valve to the right ventricle. The catheter was then manipulated under two-dimensional echocardiography and the tip's position was strictly adapted, using two different classic views before sampling. The success rate in visualizing the forceps and in defining the site of sampling was 100 percent, and no complication was noted. Radiation exposure was largely reduced. Two-dimensional echocardiography to guide endomyocardial biopsy may reduce the risk of perforation by a better anatomic definition of the sampling site. It permits sampling from different ventricular sites or from the same site during serial procedures for monitoring evolution or treatment.
