To assess the superior anatomic positioning of echocardiographic‐guided endomyocardial biopsy compared to traditional fluoroscopic‐guided technique, these two modalities were compared in a blinded fashion during femoral sheath endomyocardial biopsy in 21 patients, 19 being evaluated after orthotopic cardiac transplantation. The simultaneous fluoroscopic and echocardiographic imaging indicated that traditional fluoroscopic positioning of the bioptome against the septum is inaccurate in over half of patients undergoing biopsy. This finding should be considered in cardiomyopathy patients or those at high risk for biopsy‐related complications. © 1993 Wiley‐Liss, Inc.
