Simultaneous transplantation of the heart and kidney.
BACKGROUND
Multiple organ transplants have become frequent. Combined heart-and-kidney grafting has been reported recently and we have pursued this in selected cases.


OBJECTIVE
To devise a protocol for simultaneous heart-and-kidney transplantation, review our clinical experience with the procedure and the causes of cardiac and renal disease in this group.


METHODS
Seven patients with advanced cardiac failure (LV ejection fraction < 0.29 units; five with IDCM), and chronic renal failure (serum creatinine > 375 mumol/L) due to a variety of causes, were accepted for combined heart-and-kidney transplantation. Four males, of mean age 33 years, underwent the procedure. Each received his organs from a single cadaveric donor with ABO blood group compatibility and a negative 'current' lymphocytotoxic cross-match, but without regard to HLA-antigen matching. Cardiac ischaemic time averaged 3 hours 40 minutes, the renal first warm time was 0 minutes in all cases, and renal cold and second warm ischaemic times averaged 5 hours 17 minutes and 52 minutes respectively. The heart was grafted first and the kidney second in a procedure which averaged seven hours. Immunosuppression was achieved by induction with antithymocyte globulin, thence steroids, azathioprine and cyclosporin A.


RESULTS
No patient required post-operative dialysis. One patient had early urological complications requiring operative correction, but no serious opportunistic infections were observed. Early cardiac rejection on biopsy (ISHT grade 3a) was seen in three patients at four-ten weeks and responded promptly to increased steroids, but severe steroid-resistant rejection of both heart and kidney contemporaneously occurred in one of these three at 19 months and required a course of muromonab-CD3. All four patients developed hypertension. Mean creatinine clearance was 1.23 +/- 0.22 mL/second (74 +/- 13 mL/minute) at last follow-up. All four recipients were alive, well and rehabilitated 5, 20, 28 and 35 months after grafting. Two patients died while waiting for the double procedure and another patient eventually died after being taken off the dual waiting list and receiving a renal transplant only.


CONCLUSIONS
In experienced hands, combined heart-and-kidney transplantation is feasible and offers a compelling therapeutic solution in the treatment of advanced cardiac and renal failure. IDCM is a frequent cause of the heart failure in this group.
