Abstract

Background

Chronic kidney disease (CKD) is an established risk factor for incident cardiovascular disease and progression of heart failure disease state, and is associated with decreased survival after left ventricular assist device (LVAD) therapy or heart transplantation (HT). Combined heart-kidney transplantation (HKT) compared with isolated HT recently has been shown to have survival advantage among patients whose estimated glomerular filtration rate is less than 37 ml/min/m2. Data on LVAD to HKT are limited.

Methods

At our center, a total of 803 patients have received HT, 594 patients LVAD therapy, and 23 patients HKT from single donors; of those 23, 15 were without the use of LVAD and 8 were after support with LVAD.

Results

Kaplan-Meier survival analysis found LVAD-supported patients with CKD stages 4 or 5 had statistically worse 24-month survival after HT as compared with those with CKD stage 1, 2, and 3 (58% vs 88%, p=0.01). Patients who received combined HKT after LVAD had comparable 24-month survival with those who received HKT without LVAD (87% and 85%, p=NS); both groups had numerically better survival compared with those who had CKD (stage 4-5) with isolated HT (58%).

Conclusions

Patients supported with LVAD who demonstrate advanced CKD (stage 4-5) have worse 24-month post-HT survival compared with those with less advanced CKD (stage 1-3). Combined HKT after LVAD support is feasible and confers comparable 24-month survival compared with HKT without prior LVAD therapy. Our study supports combined HKT for select LVAD patients with advanced CKD (stage 4-5).
