title: Tampa Bay catheter: a new guiding catheter for endomyocardial biopsy via femoral approach.
abstract: Initially, endomyocardial biopsies were obtained almost exclusively using the jugular vein approach. Lately, the femoral vein route has gained popularity and in many centers, including ours, it is preferred. Despite this, guiding catheters specifically designed for endomyocardial biopsy via femoral vein approach are not available. Here, the experience with the Tampa Bay catheter, designed for endomyocardial biopsy using the femoral vein is described. From 1-1-89 to 1-31-90, a total of 486 endomyocardial biopsies were performed in 78 post-heart transplant patients (1-17, mean 6 per patient); 106 were performed via internal jugular vein (22%) and 380 (78%) via femoral vein. Of these, 100 were performed using the Tampa Bay catheter. The remaining 280 biopsies were done using a long sheath or a Judkin's right coronary angioplasty guiding catheter. Biopsy specimens were adequate for diagnosis of rejection in all 106 biopsies performed via internal jugular vein (100%) in 99 of 100 biopsies via femoral vein using the Tampa Bay catheter (99%) and in 274 of the 280 (98%) biopsies using the long sheath or the right Judkin's coronary angioplasty guiding catheter (NS). The femoral vein is larger and easier to find than the internal jugular vein. More important, complications such as right pneumothorax, Horner's syndrome, recurrent laryngeal nerve paralysis, and right phrenic nerve paralysis, known to occur when the internal jugular vein approach is used, can be completely avoided when the femoral vein approach is used.
