Abstract
The use of two-dimensional echocardiography in four successive views was assessed to determine the optimal view for localizing a transvenous percutaneous bioptome in 23 consecutive patients undergoing right ventricular endomyocardial biopsy. The biopsy catheter tip was viewed in 21 (91%) of the 23 patients. The apical four chamber view allowed visualization of the bioptome head in 19 patients (83%), the subcostal view in 8 (34%) and the long-axis view in 4 (17%). The parasternal short-axis view was not helpful in any patient. Biplane fluoroscopy was not reliable in localizing the bioptome head against the interventricular septum and did not identify inadvertent septal perforation in one patient. Echocardiography also can be used to immediately identify possible complications.
