Session Name: Poster Session B: Lung Transplantation Poster Session

Location: Hall D1
Purpose: The effect of preoperative pulmonary hypertension (PH)[mdash]that is, mean pulmonary artery pressure (mPAP) of 25mmHg or higher[mdash]on lung transplantation (LTx) outcomes is debatable.
Methods: We reviewed the charts of patients undergoing LTx at our institution from 01/01/2014–12/31/2015. Patients were grouped based on mPAP at time of listing: (Group A: <25mmHg; Group B: ≥25 & <30mmHg; and Group C: ≥30mmHg). Pairwise comparisons were made and survival was estimated using Kaplan-Meier analysis. Values were deemed significant at p<0.05.
Results: In total, 166 patients underwent LTx during the study period, 160 (96%) of which were bilateral LTx. Of the 166 patients, 80 (48.2%) were in Group A, 39 (23.5%) in Group B, and 47 (28.3%) in Group C. The 3 groups were similar in terms of age, sex, and lung allocation score [Fig. 1] Patients in Group C had significantly lower functional status, were more likely to be ventilated at time of listing, and had higher cardiopulmonary bypass (CPB) usage than Group A. Rates of grade-3 primary graft dysfunction at 48-72 hours post-LTx were similar across groups (A: 25%; B: 30.7%; C: 27.7%). The 3 groups had comparable rates of takeback to operating room, post-LTx ventilator duration, and length of stay. 1-year post-LTx hospital days were similar across groups. 30-day, 90-day, and 1-year survival rates were also comparable across groups (A: 98.8%, 96%, and 93%; B: 100%, 100%, and 100%; C: 97.9%, 97.9%, and 88%, respectively; [Fig. 1] . A Cox Regression model showed comparable risk of death in Groups B and C as compared to Group A (p=0.9; Group B: HR 1.08, 95% CI [0.28, 4.21]; Group C: HR 1.05, 95% CI [0.98, 1.14]).
