Endomyocardial biopsy in heterotopic heart transplant recipients via the femoral vein.
The results of endomyocardial biopsy (EMB) via the femoral vein in heterotopic heart transplant recipients were retrospectively analyzed and compared with those obtained using the right internal jugular vein approach. A total of 139 EMB were performed in 8 patients using the femoral (35) or the jugular (104) approach. Twenty three (64.7%) of the procedures performed via the femoral vein were part of the yearly hemodynamic and coronary artery study, and 12 (35.3%) constituted a routine postoperative evaluation of the myocardium rejection state in patients with imperviousness of the right internal jugular vein. Comparing the results obtained with the femoral approach, we observed a higher overall success rate (94.3 vs 88.5%, NS) and obtained more samples that were useful for histologic evaluation (95.5 vs 85.9%, NS); with the jugular procedure, the fragments were significatively larger in diameter (1.28 +/- 0.55 vs 1.61 +/- 0.85 mm, mean +/- SD) and in area (1.49 +/- 1.16 vs 2.28 +/- 2.24 mm2, mean +/- SD). No cardiac or local complications were noted when the femoral approach was used, while two attempts to perform biopsy via the jugular vein resulted in obstruction of this vessel. Our data suggest that the femoral venous approach for endomyocardial biopsy in heterotopic heart transplant recipients is a valid alternative to the more commonly used routes.
