Donation after circulatory death (DCD) has the potential to expand the lung donor pool. We aimed to assess whether DCD affected the need for perioperative extracorporeal membrane oxygenation (ECMO) and perioperative outcomes in lung transplantation (LTx) as compared to donation after brain death (DBD). All consecutive LTx performed between April 2017 and March 2019 at our tertiary centre were analysed. Donor and recipient preoperative characteristics, utilization of ECMO and perioperative clinical outcomes were compared between DCD and DBD LTx. Multivariate models (frequentist and Bayes) were fitted to evaluate an independent effect of DCD on the intra‐ and postoperative need for ECMO. Out of 105 enrolled patients, 25 (23.8%) were DCD LTx. Donors’ and preoperative recipients’ characteristics were comparable between the groups. Intraoperatively, mechanical circulatory support (MCS) was more common in DCD LTx (56.0% vs. 36.2%), but the adjusted difference was minor (RR=1.16, 95%CI 0.64‐2.12; p=0.613). MCS duration, first and second lung ischemia time were longer in the DCD group. Postoperatively, DCD recipients more commonly required ECMO (32.0% vs. 7.5%) and the difference remained considerable after adjustment for the pre‐ and intraoperative covariates: RR=4.11 (95%CI 0.95‐17.7), p=0.058, Bayes RR=4.15 (95%CrI 1.28‐13.0). Sensitivity analyses (two DCD‐DBD matching procedures) supported a higher risk of postoperative ECMO need in DCD patients. Incidence of delayed chest closure, postoperative chest drainage, and renal replacement therapy was higher in the DCD group. Early postoperative outcomes after DCD LTx appeared generally comparable to those after DBD LTx. DCD was associated with a higher need for postoperative ECMO which could influence clinical outcomes. However, as the DCD group had a significantly higher use of EVLP with more common ECMO preoperatively, this might have contributed to worse outcomes in the DCD group.

Recent advances in the management of patients with adult congenital heart disease (ACHD) have led to an increased number of patients who may develop heart failure and require heart transplantation (HTx). The purpose of this study was to evaluate early and mid-term postoperative outcomes after HTx with the use of Organ Care System (OCS) in a cohort of ACHD patients transplanted at our tertiary center. All consecutive HTx performed from January 2015 to January 2019 at our institution were analyzed. Donor and recipient preoperative characteristics, intraoperative course, and perioperative clinical outcomes were evaluated. Nine patients with median age of 44 years (range 17–61 years) underwent isolated HTx for end-stage ACHD during the study period. Mean cold ischemic time was 84 ± 17 minutes. Postoperatively, four patients (44%) needed venoarterial extracorporeal membrane oxygenation (1–7 days). One patient (11%) required surgical re-exploration for bleeding. Thirty-day and 1-year mortality were 11% and 22%, respectively. In our experience, despite the challenges of transplantation in ACHD, these patients can be successfully transplanted with the use of the OCS in a highly specialized center. Careful donor and recipient selection are of paramount importance.

OBJECTIVES: Studies concerning factors associated with long-term outcomes in adult congenital heart disease (ACHD) patients after infective endocarditis (IE) are scarce, while IE-related mortality in these patients remains a burden. We evaluated the factors associated with long-term survival in ACHD patients admitted for IE. METHODS: We performed a retrospective single-centre study of all ACHD patients admitted for IE to a tertiary cardiothoracic centre between 1999 and 2015. Underlying ACHD, detailed echocardiographic and clinical data, surgical treatment and long-term follow-up were analysed. RESULTS: We identified 151 ACHD patients admitted due to 176 episodes IE with 30-day, 6-month and 1-, 5- and 10-year survival of 95.4%, 92.7%, 92.7%, 84.7% and 75.6%, respectively. In a multivariable analysis, adjusted estimated probability of death was consistently higher after an IE episode among patients with complex as compared to simple/moderate ACHD: 10.6% vs 2.4% at 30 days, 15.0% vs 3.4% at 6 months and 1 year, 30.4% vs 7.8% at 5 years and 44.9% vs 13.1% at 10 years. Risk of death was higher among patients with prosthetic valve in comparison with those without (risk ratios 1.73–1.92). Surgical treatment was required in 76 (43.2%) episodes with 30-day mortality of 3.9%. Risk of death appeared to be lower than in the conservatively treated subgroup (risk ratios 0.71–0.78). CONCLUSIONS: We demonstrated satisfactory long-term survival in ACHD patients who were treated for IE in a tertiary cardiothoracic centre. Early mortality tended to be lower in the surgically treated subgroup. Factors negatively associated with long-term survival were complex ACHD and presence of prosthetic valve.
