Abstract
BACKGROUND United Network for Organ Sharing (UNOS) allocation criteria changed in 2018 to accommodate the increased prevalence of patients on a ventricular assist device as a bridge to heart transplant and prioritize sicker people in anticipation of a heart graft. We aimed to assess the impact of patient age in the new allocation policy on mortality following heart transplantation. Secondary outcomes included the effect of age ≥70 on post-transplant events, including stroke, dialysis, pacemaker, and rejection requiring treatment. METHODS The UNOS Registry was queried to identify patients who underwent heart transplants alone in the US between 2000 and 2021. Patients were divided into groups according to their age (over 70 and under 70 years old). RESULTS Patients aged over 70 were more likely to require dialysis during follow-up, but less likely to experience rejection requiring treatment, compared with patients aged <70. Age ≥70 in the new allocation system was a significant predictor of 1-year mortality (adjusted HR: 1.41; 95% CI: 1.05-1.91; p = .024), but its effect on 5-year mortality was not significant after adjusting for potential confounders (adjusted HR: 1.27; 95% CI:.97-1.66; p = .077). Undergoing transplantation under the new allocation policy vs the old allocation policy was not a significant predictor of mortality in patients over 70 years old. CONCLUSIONS Age ≥70 is a significant predictor of 1-year mortality following heart transplantation, but not at 5 and 10 years; however, the new allocation does not seem to have changed the outcomes for this group of patients.

Abstract
BACKGROUND Evidence of decline in native renal function after heart transplantation (HTx) in the Asian population is limited. This study determined the incidence and risk factors associated with declining kidney function after HTx and its impact on survival. METHODS A retrospective study of consecutive adult heart transplant patients was conducted in a single center between 2010 and 2020. The decline in kidney function was defined as the presence of one of the following criteria, including a ≥ 40% decline in eGFR, absolute value <15 mL/min/1.73 m2 (calculated by the CKD-EPI method), doubling of serum creatinine, or dialysis. RESULTS A total of 79 patients (77% male, mean age 44.5 ± 11.53 years, with a mean eGFR at discharge from the heart transplant admission of 87.9 ± 25.48 mL/min/1.73 m2 ) were included. During the median follow-up of 42 months, the rate of decline in eGFR was 3.9 mL/min/1.73 m2 per year, with a cumulative probability of decline in kidney function of 22% at 1 year and 43% at 5 years. The need for dialysis was 2.5% at 1 year and 5% at 5 years. The decline in kidney function within 1 year after discharge (hazard ratio (HR), 22.24; p = .007) and pre-HTx diabetes mellitus (DM) (HR, 8.99; p = .034) were independently associated with the need for dialysis. Post-HTx dialysis predicted all-cause mortality (HR, 4.47; p = .017). CONCLUSIONS Approximately 20% of HTx patients developed a decline in kidney function within 1 year after discharge. These individuals and pre-HTx DM patients needed preventive measures to prevent progression to chronic dialysis, which impacted survival. (thaiclinicaltrials.org number, TCTR20230620004).

Abstract
BACKGROUND Predicted heart mass (PHM) is a commonly used tool for donor-to-recipient size matching. However, incorporating body weight as part of PHM can be considered problematic given its high variability, and low metabolic nature of fat. We sought to assess whether substituting the actual donor and recipient weight with the ideal body weight (IBW) would affect the association of donor-to-recipient PHM ratio with 1-year and overall survival after heart transplantation. METHODS The United Network for Organ Sharing (UNOS) database was queried for adult patients who received a primary heart transplant between January 2000 and September 2021. RESULTS Both PHM and ideal PHM (IPHM) ratios were associated with one-year (PHM: p = .003; IPHM: p = .0007) and overall (PHM: p = .02; IPHM: p = .02) survival. In the continuous analysis with restricted cubic splines, both PHM (p = .0003) and IPHM (p = .00001) were associated with relative hazards of death. CONCLUSION IPHM is significantly associated with post-transplant survival and may be a useful compliment to PHM.

Abstract
BACKGROUND Recent innovations in temperature-controlled cardiac transportation allow for static hypothermic preservation of transplant organs during transportation. We assessed differences in donor-derived cell-free DNA (dd-cfDNA) using the SherpaPak cardiac transport system (SCTS) and traditional ice transportation. METHODS Single-organ heart transplant recipients between January 2020 and January 2022 were included if they had dd-cfDNA measures ≤6 weeks post-transplant along with the baseline biopsy at 6 weeks as part of the surveillance protocol and no biopsy-confirmed rejection ≤90 days. Elevated dd-cfDNA ≥.20% were compared between groups using logistic regression including a subject effect. RESULTS Of 65 hearts transplanted, 30 were transported with SCTS and 35 on ice. Recipient characteristics were similar between groups. Donors in the SCTS group were older (34 vs. 40 years, p = .04) with a longer total ischemic time (171 vs. 212 min, p = .002). Recipients in the SCTS group had a greater risk of elevated dd-cfDNA unadjusted and adjusted for donor age, and prolonged ischemic times > 3.5 h (Unadjusted odds ratio: 4.9, 95%-CI: 1.08-22.5, p = .039 and Adjusted odds ratio: 5.5, 95%-CI: 1.03-29.6, p = .046). Primary graft dysfunction rates and 1-year mortality were comparable between groups. CONCLUSION Elevated dd-cfDNA in patients procured with SCTS may indicate that graft injury was not negated relative to ice transport. However, there were no clinical differences noted in short or long-term outcomes including mortality despite a longer ischemic time in the SCTS group.

Abstract
PURPOSE OF THE REVIEW Cardiac allograft vasculopathy (CAV) is a progressive fibroproliferative disease which occurs after heart transplantation and is associated with significant long-term morbidity and mortality. Currently available strategies including statins, mammalian target of rapamycin (mTOR) inhibitors, and revascularization, have limited overall effectiveness in treating this pathology once the disease process is established. mTOR inhibitors, while effective when used early in the disease process, are not well tolerated, and hence not routinely used in post-transplant care. RECENT DATA Recent work on rodent models have given us a novel mechanistic understanding of effects of ascorbic acid in preventing CAV. TET methyl cytosine dioxygenase2 (TET2) reduces vascular smooth muscle cell (VSMC) apoptosis and intimal thickening. TET2 is repressed by interferon γ (IFNγ) in the setting of CAV. Ascorbic acid has been shown to promote TET2 activity and attenuate allograft vasculopathy in animal models and CAV progression in a small clinical trial. SUMMARY CAV remains a challenging disease process and needs better preventative strategies. Ascorbic acid improves endothelial dysfunction, reduces reactive oxygen species, and prevents development of intimal hyperplasia by preventing smooth muscle cell apoptosis and hyperproliferation. Further large-scale randomized control studies of ascorbic acid are needed to establish the role in routine post-transplant management.

Abstract
BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) is a serious complication of pediatric heart transplant (PHTx). 18F-FDG PET/CT has been used to differentiate early lympho-proliferation from more advanced PTLD. We report our experience with PET/CT in the management of PTLD following PHTx. METHODS This was a retrospective study of 100 consecutive PHTx recipients at our institution between 2004 and 2018. Patients who underwent PET/CT or conventional CT scans to evaluate for PTLD or high Epstein-Barr viral load were included. RESULTS Males, eight females. Median age at transplant was 3.5 months (IQR = 1.5-27.5). Median age at PTLD diagnosis was 13.3 years (IQR = 9.2-16.1). Median time between transplant and PTLD diagnosis was 9.5 (IQR = 4.5-15) years. Induction agents were used in 12 patients (50%): Thymoglobulin (N = 9), anti-IL2 (N = 2), and Rituximab (N = 1). Eighteen patients (75%) had PET/CT, of whom 14 had 18FDG-avid PTLD. Six had conventional CT. Nineteen patients (79.2%) had diagnostic biopsy confirmation of PTLD, and 5 (20.8%) had excisional biopsies. Two patients had Hodgkin's lymphoma; nine had monomorphic PTLD; eight had polymorphic PTLD; five were classified as other. Nine patients had monomorphic PTLD, including seven with diffuse large cell lymphoma (DLBC) and one with T cell lymphoma. The majority (16/24) had multi-site involvement at PTLD diagnosis, and PET/CT showed that 31.3% (5/16) had easily accessible subcutaneous nodes. Seventeen patients (overall survival 71%) underwent successful treatment without recurrence of PTLD. Of seven deaths (7/24, 29%), five had DLBC lymphoma, one had polymorphic PTLD and one had T-cell lymphoma. CONCLUSION PET-CT allowed simultaneous anatomical and functional assessment of PTLD lesions, while guiding biopsy. In patients with multiple lesions, PET/CT revealed the most prominent and active lesions, improving diagnostic accuracy.

Abstract
BACKGROUND Recent evidence has demonstrated that transplantation of hearts with blood culture positive donors (BCPDs) to pediatric recipients is safe and effective. Few studies have analyzed the effect of BCPD on adult heart transplant recipients. METHODS The United Network for Organ Sharing (UNOS) database was retrospectively reviewed from September, 1987 to March, 2021. Exclusion criteria included pediatric donors/recipients, donor ejection fraction <10% or >85%, inactive listed recipients, donors missing blood cultures, and recipients missing follow-up time. Outcomes were compared with fully adjusted logistic models. To account for discrepancies in BCPD and non-BCPD covariates, an inverse proportionally weighted model with regression adjustment (IPWRA) was used. RESULTS A total of 60 592 donors were non-BCPD, while 4009 were BCPD. 7% of hearts not transplanted were BCPD, while 6% of hearts transplanted were BCPD (p = .001). These rates have been nearly constant since 2005. There were no differences in short term survival between the two groups in the adjusted or IPWRA models (p = .103 and .277, respectively). Additionally, the BCPD group had longer ischemic time (3.24 vs. 3.06 h, p < .001), older donor age (32.73 vs. 31.65 years, p < .001), and older recipient age (52.76 vs. 52.09 years, p = .001). The IPWRA revealed an average additional 3.4 years of overall survival and 2.25 years of graft function for BCPD versus non-BCPD recipients, although these results failed to reach statistical significance (p = .387 and .527, respectively). CONCLUSIONS Given the need for more donor hearts, donors with positive blood cultures should be considered. Great care in evaluating such patients is advised to eliminate donors with untreated infections, while carefully selected donors can be considered and used.

Abstract
AL amyloidosis is a rare condition characterized by the overproduction of an unstable free light chain, protein misfolding and aggregation, and extracellular deposition that can progress to multiorgan involvement and failure. To our knowledge, this is the first worldwide report to describe triple organ transplantation for AL amyloidosis and triple organ transplantation using thoracoabdominal normothermic regional perfusion recovery with a donation from a circulatory death (DCD) donor. The recipient was a 40-year-old man with multiorgan AL amyloidosis with a terminal prognosis without multiorgan transplantation. An appropriate DCD donor was selected for sequential heart, liver, and kidney transplants via our center's thoracoabdominal normothermic regional perfusion pathway. The liver was additionally placed on an ex vivo normothermic machine perfusion, and the kidney was maintained on hypothermic machine perfusion while awaiting implantation. The heart transplant was completed first (cold ischemic time [CIT]: 131 minutes), followed by the liver transplant (CIT: 87 minutes, normothermic machine perfusion: 301 minutes). Kidney transplantation was performed the following day (CIT: 1833 minutes). He is 8 months posttransplant without evidence of heart, liver, or kidney graft dysfunction or rejection. This case highlights the feasibility of normothermic recovery and storage modalities for DCD donors, which can expand transplant opportunities for allografts previously not considered for multiorgan transplantations.

Abstract
The long-term safety of heart transplants from hepatitis C viremic (NAT+) donors remains uncertain. We conducted a prospective study of all patients who underwent heart transplantation at our center from January 2018 through August 2020. Routine testing was performed to assess for donor-derived cell-free DNA, acute cellular rejection (ACR), antibody-mediated rejection (AMR), and cardiac allograft vasculopathy (CAV). Allograft dysfunction and mortality were also monitored. Seventy-five NAT- recipients and 32 NAT+ recipients were enrolled in the study. All NAT+ recipients developed viremia detected by PCR, were treated with glecaprevir/pibrentasvir at the time of viremia detection, and cleared the virus by 59 days post-transplant. Patients who underwent NAT testing starting on post-operative day 7 (NAT+ Group 1) had significantly higher viral loads and were viremic for a longer period compared with patients tested on post-operative day 1 (NAT+ Group 2). Through 3.5 years of follow-up, there were no statistically significant differences in timing, severity, or frequency of ACR in NAT+ recipients compared with the NAT- cohort, nor were there differences in noninvasive measures of graft injury, incidence or severity of CAV, graft dysfunction, or mortality. There were five episodes of AMR, all in the NAT- group. There were no statistically significant differences between Group 1 and Group 2 NAT+ cohorts. Overall, these findings underscore the safety of heart transplantation from NAT+ donors.

Abstract
Outcomes following heart transplantation remain suboptimal with acute and chronic rejection being major contributors to poor long-term survival. IL-6 is increasingly recognized as a critical pro-inflammatory cytokine involved in allograft injury and has been shown to play a key role in regulating the inflammatory and alloimmune responses following heart transplantation. Therapies that inhibit IL-6 signaling have emerged as promising strategies to prevent allograft rejection. Here, we review experimental and pre-clinical evidence that supports the potential use of IL-6 signaling blockade to improve outcomes in heart transplant recipients.

Abstract
INTRODUCTION Recipient functional status prior to transplantation can significantly impact post-transplant survival. METHODS The United Network for Organ Sharing database was queried for adult heart transplants including data on functional capacity and from February 1, 2005 to March 1, 2021; there were 32 875 cases included. The four functional categories studied were based on adult daily activities of living and were separated into total assistance required, some assistance required, no assistance required, and near death. Survival outcomes were compared for recipient's pretransplant level of functional status versus those with near death status. These were compared using adjusted logistic regression (odds of death at 30 days and 1 year) and conditional Cox models (overall survival and time until post-transplant rejection). All models were adjusted for donor age, sex, ethnicity, ischemic time, as well as recipient age, sex, ethnicity, length of stay, UNOS region, ventricular assist device, creatinine, days on the waiting list, and status at transplant. RESULTS There were 12 953 recipients classified as "near death" or "severely disabled"; 7711 "required total assistance in daily living", 7,328 "needed some", and 4883 "needed none". In adjusted models, the probabilities of death for the lowest functioning groups within 30 days and 1 year were 5% and 10%, respectively. Those "requiring total assistance" had analogous probabilities of 3% (OR = 0.58; p < 0.001) and 9% (OR = 0.81; p < 0.001). Those "requiring some assistance" had probabilities of 3% (OR = 0.56; p < 0.001) and 9% (OR = 0.74; p < 0.001). Lastly, those "requiring no assistance" had probabilities of death of 2% (OR = 0.35; p < 0.001) and 7% (OR = 0.63; p < 0.001). CONCLUSION Recipient functional status assessed pre-transplant and recorded in the UNOS database is a strong predictor of post-transplant survival.

Abstract
INTRODUCTION The Organ Care System (OCS) is an ex vivo perfusion platform for donor heart preservation. Short/mid-term post-transplant outcomes after its use are comparable to standard cold storage (CS). We evaluated long-term outcomes following its use. METHODS Between 2011 and 2013, 38 patients from a single center were randomized as a part of the PROCEED II trial to receive allografts preserved with CS (n = 19) or OCS (n = 19). Endpoints included 8-year survival, survival free from graft-related deaths, freedom from cardiac allograft vasculopathy (CAV), non-fatal major adverse cardiac events (NF-MACE), and rejections. RESULTS Eight-year survival was 57.9% in the OCS group and 73.7% in the CS group (p = .24). Freedom from CAV was 89.5% in the OCS group and 67.8% in the CS group (p = .13). Freedom from NF-MACE was 89.5% in the OCS group and 67.5% in the CS group (p = .14). Eight-year survival free from graft-related death was equivalent between the two groups (84.2% vs. 84.2%, p = .93). No differences in rejection episodes were observed (all p > .5). CONCLUSIONS In select patients receiving OCS preserved allografts, late post-transplant survival trended lower than those transplanted with an allograft preserved with CS. This is based on a small single-center series, and larger numbers are needed to confirm these findings.

Abstract
BACKGROUND Cardiac allograft vasculopathy (CAV) causes late graft dysfunction and post-transplant mortality. Currently, the effects of different donor-specific antibodies (DSA) on the severity of CAV remain unclear. METHOD We evaluated 526 adult heart transplant recipients at a single center between January 2010 and August 2015. Subjects were divided into those with DSA (n = 142) and those without DSA (n = 384, control). The DSA group was stratified into persistent DSA (n = 34), transient DSA (n = 105), 1:8 dilution DSA (n = 45), complement-binding (C1q) DSA (n = 36), Class I DSA (n = 37), and Class II DSA (n = 105). The primary outcome was the incidence of moderate-to-severe CAV (CAV 2/3) at 5-year follow-up. RESULTS Subjects with persistent DSA, 1:8 dilution DSA, and C1q DSA had higher incidence of CAV 2/3 compared the control group (17.6%, 13.3%, and 16.7% vs. 3.1%, respectively; P≤ .001). The incidence of CAV 2/3 between subjects with transient DSA and the control group was similar (2.8% vs. 3.1%; P = .888). Subjects with Class II DSA also had higher incidence of CAV 2/3 (7.6% vs. 3.1%; P = .039). CONCLUSION DSA that are persistent, 1:8 dilution positive, C1q positive, and Class II are associated with more severe grades of CAV. These DSA characteristics may prognosticate disease and warrant consideration for treatment.

Abstract
Extended-release tacrolimus for prophylaxis of allograft rejection in orthotopic heart transplant (OHT) recipients is currently not FDA-approved. One such extended-release formulation of tacrolimus known as LCPT allows once-daily dosing and improves bioavailability compared to immediate-release tacrolimus (IR-tacrolimus). We compared the efficacy and safety of LCPT to IR-tacrolimus applied de novo in adult OHT recipients. Twenty-five prospective recipients on LCPT at our center from 2017 to 2019 were matched 1:2 with historical control recipients treated with IR-tacrolimus based on age, gender, and baseline creatinine. The primary composite outcome of death, acute cellular rejection, and/or new graft dysfunction within 1 year was compared using non-inferiority analysis. LCPT demonstrated non-inferiority to IR-tacrolimus, with a primary outcome risk reduction of 20% (90% CI: -40%, -.5%; non-inferiority P = .001). Tacrolimus trough levels peaked at 2-3 months and were higher in LCPT (median 14.5 vs. 12.7 ng/ml; P = .03) with similar dose levels (LCPT vs. IR-tacrolimus: .08 vs. .09 mg/kg/day; P = .33). Cardiovascular-related readmissions were reduced by 62% (P = .046) in LCPT patients. The complication rate per transplant admission and all-cause readmission rate did not differ significantly. These results suggest that LCPT is non-inferior in efficacy to IR-tacrolimus with a similar safety profile and improved bioavailability in OHT.

Abstract
BACKGROUND Atrial flutter is the most common arrhythmia post cardiac transplantation. Observational studies in the non-transplant population have shown prognostic benefit with catheter ablation; however, there are no data in the heart transplant population. OBJECTIVES This study evaluated the experience of catheter ablation in atrial flutter post cardiac transplantation. METHODS A retrospective review of experience of late onset atrial flutter at the Freeman Hospital, Newcastle-upon-Tyne, UK, between 1985 and January 2020. RESULTS Sixty eight of the 722 patients who survived 6 months post cardiac transplantation developed late atrial flutter giving an incidence of 9.4%. Thirty-two patients were managed with ablation with treatment largely determined by time of flutter onset. Kaplan Meier estimates for arrhythmia free survival post first ablation for organized atrial arrhythmias was 83.3% at 1 year. Kaplan-Meier estimates for median survival post onset of atrial arrhythmias treated with ablation was 11.34 years (95% CI 8.00-14.57), compared to 5.79 years in patients managed medically (95%CI 2.26-9.32) (P = .026). CONCLUSIONS Atrial flutter is an important late complication of cardiac transplantation. Patients treated with ablation in the modern era had increased survival compared to a historical cohort.

Abstract
PROBLEM Mathematical modeling suggests aggressive ganciclovir dosing in the first week of cytomegalovirus disease (CMV) treatment may improve response. This has not been evaluated clinically. METHODS Adult kidney and/or pancreas transplant recipients admitted with CMV (4/29/19-7/15/20) received IV ganciclovir(10 mg/kg Q12 h × 7 days) with step-down to standard-of-care (SOC) dosing thereafter (5 mg/kg Q12). A SOC cohort admitted before implementation of the dosing strategy (10/20/16-3/2/19) served as a comparator. PRIMARY OBJECTIVE rate of viral clearance (delta log CMV) at therapy day 7. SECONDARY OBJECTIVE safety/short term efficacy. RESULTS Fifty-four patients met inclusion criteria; 22 high-dose, 32 SOC. Demographics were similar with the exception of more women (45.4% vs. 15.6%,P = .03) and higher presenting viral-load in the high-dose group (log 6.0±.7 vs. log 5.2±1.2, P = .02). High-dose resulted in significantly greater response to therapy at day 7 (log -.92±.51 vs. log -.56±.79, P = .04). Change in WBC at day 7 was not different (-.49±1.92 vs. -.45±5.1, P = .97). Short-term clinical outcomes were similar between groups including mean hospital length-of-stay (P = .52), readmission rates (30 d: P = .38; 90 d: P = .5) and achievement of CMV viral-load less-than-lower-limit-of-quantification by day 90 (73% vs. 84%, P = .06). Rejection after CMV as well as graft/patient survival were similar between groups (P = .56, P > .99, P > .99). CONCLUSION A high-dose IV ganciclovir strategy results in improved viral clearance kinetics without safety concerns and similar short term clinical outcomes.

Abstract
BACKGROUND Early aspirin (ASA) use after orthotopic heart transplantation (OHT) has been associated with lower rates of cardiac allograft vasculopathy (CAV). We hypothesized that the inverse association between ASA use and CAV incidence may be most pronounced in patients with allograft rejection. METHODS Patients receiving OHT at a single center 2004-2010 (n = 120) were categorized by early ASA use post-transplant (ASA use for > 6 months in the first year) and the presence of biopsy-defined acute cellular rejection (ACR) and/or antibody-mediated rejection (AMR) during 5-year follow-up. Propensity scores for ASA treatment were estimated using boosting models and applied by inverse probability of treatment weighting. The association between ASA use and time to moderate/severe CAV (ISHLT ≥ 2) was investigated. RESULTS Among patients with ACR or AMR, ASA therapy was associated with significantly lower rates of CAV≥ 2 (3.3 vs. 30.1%; P = .001; HRadj .07; 95% CI .01-.52), whereas ASA therapy was not associated with lower rates of CAV in patients with no rejection (5.6 vs. 5.3%; P = .90; HRadj 1.26; 95% CI .08-20.30; pinteraction = .09). CONCLUSIONS Early ASA use after OHT was associated with lower rates of moderate to severe CAV only in those patients with episodes of allograft rejection.

Abstract
Allosensitization represents a major barrier to heart transplantation (HTx). We assessed the efficacy and safety of complement inhibition at transplant in highly sensitized heart transplant recipients. We performed a single-center, single-arm, open-label trial (NCT02013037). Patients with panel reactive antibodies (PRA) ≥70% and pre-formed donor-specific antibodies (DSA) were eligible. In addition to standard of care, patients received nine infusions of eculizumab during the first 2 months posttransplant. The primary composite endpoint was antibody-mediated rejection (AMR) ≥pAMR2 and/or left ventricular dysfunction during the first year. Secondary endpoints included hemodynamic compromise, allograft rejection, and patient survival. Twenty patients were included. Median cPRA and mean fluorescence intensity of immunodominant DSA were 95% (90%-97%) and 6250 (5000-10 000), respectively. Retrospective B cell and T cell flow crossmatches were positive in 14 and 11 patients, respectively. The primary endpoint occurred in four patients (20%). Survival at 1 year was 90% with no deaths resulting from AMR. In a prespecified analysis comparing treated patients to matched control patients, we observed a dramatic reduction in the risk of biopsy-proven AMR in patients treated with eculizumab (HR = 0.36, 95% CI = 0.14-0.95, p = .032). Our findings support the prophylactic use of complement inhibition for heart transplantation at high immunological risk. ClinincalTrials.gov, NCT02013037.

Abstract
The clinical spectrum of COVID‐19 in heart transplant recipients has not been fully defined, because asymptomatic and sub‐clinical cases are difficult to capture. Seroprevalence surveys are an important tool to identify not just cases that have come to clinical attention, but all previously infected recipients. We performed a seroprevalence survey of the adult heart transplant program at a large New York City Hospital System. A total of 232 (87% of recipients being followed) subjects were tested, of whom 37 (15.9%) were found to be previously infected. This is comparable to the overall rate of prior infection in the NYC metro area. Disease course tended to be more severe than in the general population; however, this was at least partially driven by traditional risk factors of age and comorbidities. Lastly, 9 of 10 recipients who were initially found to be PCR positive subsequently tested positive for antibodies, confirming the ability of this population to mount a humoral response. In conclusion, prevalence of COVID‐19 in heart transplant recipients on immunosuppression was comparable to that in the general population of NYC, and 90% of those with an initially positive viral swab developed antibodies. In those who are infected, disease course tends to be more severe.

Abstract
T cells are implicated in the pathogenesis of cardiac allograft vasculopathy (CAV), yet their clonality, specificity, and function are incompletely defined. Here we used T cell receptor β chain (TCRB) sequencing to study the T cell repertoire in the coronary artery, endomyocardium, and peripheral blood at the time of retransplant in four cases of CAV and compared it to the immunoglobulin heavy chain variable region (IGHV) repertoire from the same samples. High-dimensional flow cytometry coupled with single-cell PCR was also used to define the T cell phenotype. Extensive overlap was observed between intragraft and blood TCRBs in all cases, a finding supported by robust quantitative diversity metrics. In contrast, blood and graft IGHV repertoires from the same samples showed minimal overlap. Coronary infiltrates included CD4+ and CD8+ memory T cells expressing inflammatory (IFNγ, TNFα) and profibrotic (TGFβ) cytokines. These were distinguishable from the peripheral blood based on memory, activation, and tissue residency markers (CD45RO, CTLA-4, and CD69). Importantly, high-frequency rearrangements were traced back to endomyocardial biopsies (2-6 years prior). Comparison with four HLA-mismatched blood donors revealed a repertoire of shared TCRBs, including a subset of recently described cross-reactive sequences. These findings provide supportive evidence for an active local intragraft bystander T cell response in late-stage CAV.

Abstract
In donation after circulatory death (DCD), cardiac grafts are subjected to warm ischemia in situ, prior to a brief period of cold, static storage (CSS) at procurement, and ex situ, normothermic, machine perfusion (NMP) for transport and graft evaluation. Cold ischemia and normothermic reoxygenation during NMP could aggravate graft injury through continued accumulation and oxidation, respectively, of mitochondrial succinate, and the resultant oxidative stress. We hypothesized that replacing CSS with hypothermic, oxygenated perfusion (HOPE) could provide cardioprotection by reducing cardiac succinate levels before NMP. DCD was simulated in male Wistar rats. Following 21 minutes in situ ischemia, explanted hearts underwent 30 minutes hypothermic storage with 1 of the following: (1) CSS, (2) HOPE, (3) hypothermic deoxygenated perfusion (HNPE), or (4) HOPE + AA5 (succinate dehydrogenase inhibitor) followed by normothermic reperfusion to measure cardiac and metabolic recovery. After hypothermic storage, tissue ATP/ADP levels were higher and succinate concentration was lower in HOPE vs CSS, HNPE, and HOPE + AA5 hearts. After 60 minutes reperfusion, cardiac function was increased and cellular injury was decreased in HOPE compared with CSS, HNPE, and HOPE + AA5 hearts. HOPE provides improved cardioprotection via succinate oxidation prior to normothermic reperfusion compared with CSS, and therefore is a promising strategy for preservation of cardiac grafts obtained with DCD.

Abstract
The absence of afferent nerves for heart rate (HR) regulation leaves the transplanted heart under the influence of its internal and hormonal control. The HR of heart transplantation (HTx) recipients varies from to 90-110 bpm, indicating a lack of vagal parasympathetic tone. We hypothesized that the reduction in mean HR using an If-channel antagonist (ivabradine) could be effective and safe in HTx recipients. The primary objective of this open-label randomized clinical trial was to compare the mean HR at 3, 6, 12, 18, 24, 30, and 36 months after randomization between an ivabradine plus conventional treatment group (IG) and conventional treatment alone group (CG). The secondary objectives were reduction in mortality, graft dysfunction, and ventricular mass. All patients were randomized between 1 and 12 months after HTx. Ivabradine started at randomization. Of the 35 patients, 54.28% were in the CG and 45.72% in the IG. There were no significant between-group differences in demographics. Over time, the HR differences between the groups became significant (P < .01). There were no significant between-group differences in mortality, graft dysfunction, and ventricular mass. We conclude that ivabradine could effectively and consistently reduce the HR in HTx recipients.

Abstract
Ischemia-reperfusion injury (IRI) is an important risk factor for accelerated cardiac allograft rejection and graft dysfunction . Utilizing a rat heart isogeneic transplant model, we identified inflammatory pathways involved in IRI in order to identify therapeutic targets involved in disease. Pathway analyses identified several relevant targets, including cytokine signaling by the IL-1 receptor (IL-1R) pathway and inflammasome activation. To investigate the role of IL-1R signaling pathways during IRI, we treated syngeneic cardiac transplant recipients at 1-hour posttransplant with Anakinra, a US Food and Drug Administration (FDA)-approved IL-1R antagonist; or parthenolide, a caspase-1 and nuclear factor kappa-light-chain-enhancer of activated B cells inhibitor that blocks IL-1β maturation. Both Anakinra and parthenolide significantly reduced graft inflammation and cellular recruitment in the treated recipients relative to nontreated controls. Anakinra treatment administered at 1-hour posttransplant to recipients of cardiac allografts from CMV-infected donors significantly increased the time to rejection and reduced viral loads at rejection. Our results indicate that reducing IRI by blocking IL-1Rsignaling pathways with Anakinra or inflammasome activity with parthenolide provides a promising approach for extending survival of cardiac allografts from CMV-infected donors.

Abstract
The XVth Banff Conference on Allograft Pathology meeting was held on September 23-27, 2019, in Pittsburgh, Pennsylvania, USA. During this meeting, two main topics in cardiac transplant pathology were addressed: (a) Improvement of endomyocardial biopsy (EMB) accuracy for the diagnosis of rejection and other significant injury patterns, and (b) the orphaned lesion known as Quilty effect or nodular endocardial infiltrates. Molecular technologies have evolved in recent years, deciphering pathophysiology of cardiac rejection. Diagnostically, it is time to integrate the histopathology of EMBs and molecular data. The goal is to incorporate molecular pathology, performed on the same paraffin block as a companion test for histopathology, to yield more accurate and objective EMB interpretation. Application of digital image analysis from hematoxylin and eosin (H&E) stain to multiplex labeling is another means of extracting additional information from EMBs. New concepts have emerged exploring the multifaceted significance of myocardial injury, minimal rejection patterns supported by molecular profiles, and lesions of arteriolitis/vasculitis in the setting of T cell-mediated rejection (TCMR) and antibody-mediated rejection (AMR). The orphaned lesion known as Quilty effect or nodular endocardial infiltrates. A state-of-the-art session with historical aspects and current dilemmas was reviewed, and possible pathogenesis proposed, based on advances in immunology to explain conflicting data. The Quilty effect will be the subject of a multicenter project to explore whether it functions as a tertiary lymphoid organ.

Abstract
Cardiac allograft vasculopathy (CAV) still is one of the most important limiting factors of long-term survival following heart transplant (HT). This study aimed to investigate the association between proinflammatory adipokine-visfatin and the incidence of CAV in HT recipients. After HT, 182 patients who had a follow-up visit at the Transplantation Clinic between 2016 and 2017 were analyzed. The median age was 60.5 years, and 76.4% were men. The incidence of CAV was 54.9%. According to the multivariable proportional hazard regression analysis, visfatin level (1.795 [1.539-2.094]; P < .001) was significantly associated with CAV, and statin use was protective against CAV (0.504 [0.32-0.793]; P = .003). The area under the receiver operating characteristic curve indicated an excellent discriminatory power of visfatin (0.9548 [0.9281-0.9816]) for CAV detection. The cutoff value of 5.42 ng/mL for visfatin yielded a sensitivity of 89% and specificity of 91%. This is the first study to demonstrate that visfatin serum concentrations are independently associated with the incidence of CAV in HT recipients. Visfatin allows for simple and cheap detection of CAV given its excellent discriminatory ability and high sensitivity and specificity. In addition, we have found an independent association between the statin use and a lower risk of CAV.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic poses special challenges to immunocompromised transplant patients. Given the paucity of proven data in treating COVID-19, management of these patients is difficult, rapidly evolving, and mainly based on anecdotal experience. We report 2 cases of heart transplant (HT) recipients with COVID-19. The first is a 59-year-old female with HT in 2012 who presented on March 20, 2020 with fever, hypoxia, and ground-glass opacities on chest X-ray. She quickly progressed to acute hypoxic respiratory failure and vasoplegic shock. Despite reduction in immunosuppression and treatment with tocilizumab, intravenous immunoglobulin, hydroxychloroquine, lopinavir/ritonavir, and broad-spectrum antibiotics, she ultimately died from multiorgan failure. The second case is a 75-year-old man with HT in 2000 who presented on April 2, 2020 after curbside testing revealed positive COVID-19. Given a milder presentation compared to the first patient, antimetabolite was discontinued and only hydroxychloroquine was started. Because of a lack of clinical improvement several days later, tocilizumab, methylprednisolone, and therapeutic anticoagulation were initiated. The patient clinically improved with decreasing oxygen requirements and was discharged home. These 2 cases highlight the wide range of different presentations of COVID-19 in HT recipients and the rapidity with which the management of these patients is evolving.

Abstract
After heart transplant, adding everolimus (EVL) to standard immunosuppressive regimen mostly relies on converting calcineurin inhibitors (CNIs) into EVL. The aim of this study was to describe the effects of combining low-dose EVL and CNIs in maintenance immunosuppression regimen (quadritherapy) and compare it with standard tritherapy associating standard-dose CNIs, mycophenolate mofetil, and corticosteroids. In the 3-year registry cohort of heart transplanted patients, those who received quadritherapy were compared with those who received tritherapy. EVL was added after 3 months posttransplant. Three analyses were performed to control for confounders: propensity score matching, multivariable survival, and inverse probability score weighting analyses. Among 213 patients who were included (75 with quadritherapy), propensity score matching selected 64 unique pairs of patients with similar characteristics. In the matched cohort (n = 128), quadritherapy was associated with fewer deaths (3 [4.7%] vs 17 [21.9%], P = .007) and biopsy-proven acute rejections (15 [23.4%] vs 31 [48.4%], P = .002). These results were confirmed in the overall cohort (n = 213), after multivariable and inverse probability score weighting analyses. Renal function and donor-specific HLA-antibodies remained similar in both groups. Low-dose combination quadritherapy was associated with fewer deaths and rejections, compared with standard immunosuppression tritherapy.

Abstract
Ischemia-reperfusion injury (IRI) and cardiac allograft vasculopathy (CAV) remain unsolved complications post-heart transplant (Tx). The antioxidant transcription factor Nuclear factor erythroid 2-related factor 2 (Nrf2) has been suggested to inhibit reactive oxygen species-mediated NF-κB activation. We hypothesized that Nrf2 inhibits NF-κB activation post-Tx and suppresses IRI and the subsequent development of CAV. IRI and CAV were investigated in murine heterotopic Tx models, respectively. Nrf2 wild-type (WT) and KO mice were used as donors. Sulforaphane was used as an Nrf2 agonist. In saline-treated animals following 24 hours of reperfusion in isogenic grafts, Nrf2-KO showed significantly less SOD1/2 activity compared with WT. Nrf2-KO displayed significantly high total and phosphorylated p65 expressions and percentage of cells with nuclear p65. mRNA levels of NF-κB-mediated proinflammatory genes were also high. Graft dysfunction, apoptosis, and caspase-3 activity were significantly higher in Nrf2-KO. In the allograft studies, graft beating score was significantly weaker in Nrf2-KO compared with WT. Nrf2-KO also demonstrated significantly more coronary luminal narrowing. In WT animals, sulforaphane successfully augmented all the protective effects of Nrf2 with increase of SOD2 activity. Nrf2 inhibits NF-κB activation and protects against IRI via its antioxidant properties and suppresses the subsequent development of CAV.

Abstract
Since the 1960s, heart and lung transplantation has remained the optimal therapy for patients with end-stage disease, extending and improving quality of life for thousands of individuals annually. Expanding donor organ availability and immunologic compatibility is a priority to help meet the clinical demand for organ transplant. While effective, current immunosuppression is imperfect as it lacks specificity and imposes unintended adverse effects such as opportunistic infections and malignancy that limit the health and longevity of transplant recipients. In this review, we focus on donor macrophages as a new target to achieve allograft tolerance. Donor organ-directed therapies have the potential to improve allograft survival while minimizing patient harm related to global suppression of recipient immune responses. Topics highlighted include the role of ontogenically distinct donor macrophage populations in ischemia-reperfusion injury and rejection, including their interaction with allograft-infiltrating recipient immune cells and potential therapeutic approaches. Ultimately, a better understanding of how donor intrinsic immunity influences allograft acceptance and survival will provide new opportunities to improve the outcomes of transplant recipients.

Abstract
Cardiac allograft vasculopathy (CAV) is associated with intragraft B cell infiltrates. Here, we studied the clonal composition of B cell infiltrates using 4 graft specimens with CAV. Using deep sequencing, we analyzed the immunoglobulin heavy chain variable region repertoire in both graft and blood. Results showed robust B cell clonal expansion in the graft but not in the blood for all cases. Several expanded B cell clones, characterized by their uniquely rearranged complementarity-determining region 3, were detected in different locations in the graft. Sequences from intragraft B cells also showed elevated levels of mutated rearrangements in the graft compared to blood B cells. The number of somatic mutations per rearrangement was also higher in the graft than in the blood, suggesting that B cells continued maturing in situ. Overall, our studies demonstrated B cell clonal expansion in human cardiac allografts with CAV. This local B cell response may contribute to the pathophysiology of CAV through a mechanism that needs to be identified.

Abstract
INTRODUCTION Patients with end-stage heart failure eligible for orthotopic heart transplantation (OHT) exceed the number of available donor organs. With highly effective hepatitis C virus (HCV) antiviral therapy now available, HCV+ organs are increasingly utilized. We seek to describe our experience with patients receiving HCV viremic organs as compared to non-HCV transplant recipients. METHODS Our center began utilizing HCV hearts in February 2018. We retrospectively reviewed baseline demographics, laboratory data and outcomes for those undergoing OHT with majority being from a viremic HCV donor. RESULTS Twenty-three of 25 HCV recipients received hearts from NAT+ donors with 22 of 23 seroconverting within 7 days. Fifteen recipients have completed HCV treatment, with the longest duration of follow-up being 13 months. No differences in rates of rejection, hospitalizations or death were seen between non-HCV and HCV transplant patients. DISCUSSION With the advent of available direct-acting antivirals (DAAs), viremic HCV hearts provide an opportunity to increase organ availability. Moreover, treatment for HCV in the setting of immunosuppression is well-tolerated and results in sustained viremic response. CONCLUSION Viremic, discordant HCV OHT can be performed in a safe and effective manner utilizing a systematic, multidisciplinary approach without an effect on short-term outcomes.

Abstract
Pathologic antibody-mediated rejection (pAMR) occurs in 10% of cardiac transplant patients and is associated with increased mortality. The endomyocardial biopsy remains the primary diagnostic tool to detect and define pAMR. However, certain challenges arise for the pathologist. Accurate identification of >10% of intravascular macrophages along with endothelial swelling, which remains a critical component of diagnosing pAMR, is one such challenge. We used double labeling with an endothelial and histiocytic marker to improve diagnostic accuracy. Twenty-two cardiac transplant endomyocardial biopsies were screened using a CD68/CD31 immunohistochemical (IHC) double stain. To determine whether pAMR diagnosis would change using the double stain, intravascular macrophage staining was compared to using CD68 alone. Twenty-two cardiac pAMR cases from patients were included. Fifty-nine percent of cases previously called >10% intravascular macrophage positive by CD68 alone were called <10% positive using the CD68/CD31 double stain. Not using the double stain was associated with a significant overcall. In C4d-negative cases, using the CD68/CD31 double stain downgraded the diagnosis of pAMR2 to pAMR1 in 32% of cases. It was concluded that more than one third of patients were overdiagnosed with pAMR using CD68 by IHC alone. We demonstrate the value of using a CD68/CD31 double stain to increase accuracy.

Abstract
Standardized donor-derived cell-free DNA (dd-cfDNA) testing has been introduced into clinical use to monitor kidney transplant recipients for rejection. This report describes the performance of this dd-cfDNA assay to detect allograft rejection in samples from heart transplant (HT) recipients undergoing surveillance monitoring across the United States. Venous blood was longitudinally sampled from 740 HT recipients from 26 centers and in a single-center cohort of 33 patients at high risk for antibody-mediated rejection (AMR). Plasma dd-cfDNA was quantified by using targeted amplification and sequencing of a single nucleotide polymorphism panel. The dd-cfDNA levels were correlated to paired events of biopsy-based diagnosis of rejection. The median dd-cfDNA was 0.07% in reference HT recipients (2164 samples) and 0.17% in samples classified as acute rejection (35 samples; P = .005). At a 0.2% threshold, dd-cfDNA had a 44% sensitivity to detect rejection and a 97% negative predictive value. In the cohort at risk for AMR (11 samples), dd-cfDNA levels were elevated 3-fold in AMR compared with patients without AMR (99 samples, P = .004). The standardized dd-cfDNA test identified acute rejection in samples from a broad population of HT recipients. The reported test performance characteristics will guide the next stage of clinical utility studies of the dd-cfDNA assay.

Abstract
BACKGROUND AND AIMS This multicenter trial compared immediate-release tacrolimus (IR-T) vs prolonged-release tacrolimus (PR-T) in de novo kidney, liver, and heart transplant recipients aged <16 years. Each formulation had similar pharmacokinetic (PK) profiles. Follow-up efficacy and safety results are reported herein. MATERIALS AND METHODS Patients, randomized 1:1, received once-daily, PR-T or twice-daily, IR-T within 4 days of surgery. After a 4-week PK assessment, patients continued randomized treatment for 48 additional weeks. At Year 1, efficacy assessments included the number of clinical acute rejections, biopsy-confirmed acute rejection (BCAR) episodes (including severity), patient and graft survival, and efficacy failure (composite of death, graft loss, BCAR, or unknown outcome). Adverse events were assessed throughout. RESULTS The study included 44 children. At Year 1, mean ± standard deviation tacrolimus trough levels were 6.6 ± 2.2 and 5.4 ± 1.6 ng/mL, and there were 2 and 7 acute rejection episodes in the PR-T and IR-T groups, respectively. No cases of graft loss or death were reported during the study. The overall efficacy failure rate was 18.2% (PR-T n = 1; IR-T n = 7). CONCLUSIONS In pediatric de novo solid organ recipients, the low incidence of BCAR and low efficacy failure rate suggest that PR-T-based immunosuppression is effective and well tolerated to 1-year post-transplantation.

Abstract
BACKGROUND Despite significant advances in durable mechanical support survival, infectious complications remain the most common adverse event after ventricular assist device (VAD) implantation and the leading cause of early death after transplantation. In this study, we aim to describe our local infectious epidemiology and review short-term survival and infectious incidence rates in the post-transplantation period and assess risk factors for infectious episodes after transplantation. METHODS Retrospective single-center study of all consecutive adult heart transplant patients from 2008 to 2017. Survival data were estimated and summarized using the Kaplan-Meier method. We quantified and evaluated the difference in the incidence rate between patients with and without infection using a Fine-Gray model. The outcome of interest is the time to first infection diagnosis with post-transplant death as the competing event. RESULTS Among 278 heart transplant patients, 74 (26.5%) underwent LVAD implantation. Twenty-one patients (28.3%) developed an infection while supported by an LVAD. When compared to patients supported by an LVAD without a preceding infection, BMI was significantly greater (31.2 vs 27.8 kg/m2 , P = .03). Median follow-up post-transplantation was 3.01 years. Significant risk factors for the competing risk regression for infection after heart transplantation include LVAD infection (HR 1.94, [95% CI] 1.11-3.39, P = .020) and recipient COPD (HR 2.14, [95% CI] 1.39-3.32, P = .001) when adjusted for recipient age, gender, hypertension, diabetes mellitus, and body mass index. CONCLUSIONS Patients with LVAD-related infection had a significantly increased risk of infectious complications after heart transplantation. Further research on the avoidance of induction agents and reduced maintenance immunosuppression in this patient population is warranted.

Abstract
The advent of direct-acting antiviral therapy for hepatitis C virus (HCV) has generated tremendous interest in transplanting organs from HCV-infected donors. We conducted a single-arm trial of orthotopic heart transplantation (OHT) from HCV-infected donors into uninfected recipients, followed by elbasvir/grazoprevir treatment after recipient HCV was first detected (NCT03146741; sponsor: Merck). We enrolled OHT candidates aged 40-65 years; left ventricular assist device (LVAD) support and liver disease were exclusions. We accepted hearts from HCV-genotype 1 donors. From May 16, 2017 to May 10, 2018, 20 patients consented for screening and enrolled, and 10 (median age 52.5 years; 80% male) underwent OHT. The median wait from UNOS opt-in for HCV nucleic-acid-test (NAT)+ donor offers to OHT was 39 days (interquartile range [IQR] 17-57). The median donor age was 34 years (IQR 31-37). Initial recipient HCV RNA levels ranged from 25 IU/mL to 40 million IU/mL, but all 10 patients had rapid decline in HCV NAT after elbasvir/grazoprevir treatment. Nine recipients achieved sustained virologic response at 12 weeks (SVR-12). The 10th recipient had a positive cross-match, experienced antibody-mediated rejection and multi-organ failure, and died on day 79. No serious adverse events occurred from HCV transmission or treatment. These short-term results suggest that HCV-negative candidates transplanted with HCV-infected hearts have acceptable outcomes.

Abstract
There are limited clinical data regarding prolonged‐release tacrolimus (PR‐T) use in pediatric transplant recipients. This Phase 2 study assessed the efficacy and safety of PR‐T in stable pediatric kidney, liver, and heart transplant recipients (aged ≥5 to ≤16 years) over 1 year following conversion from immediate‐release tacrolimus (IR‐T), on a 1:1 mg total‐daily‐dose basis. Endpoints included the incidence of acute rejection (AR), a composite endpoint of efficacy failure (death, graft loss, biopsy‐confirmed AR, and unknown outcome), and safety. Tacrolimus dose and whole‐blood trough levels (target 3.5–15 ng/ml) were also evaluated. Overall, 79 patients (kidney, n = 48; liver, n = 29; heart, n = 2) were assessed. Following conversion, tacrolimus dose and trough levels remained stable; however, 7.6–17.7% of patients across follow‐up visits had trough levels below the target range. Two (2.5%) patients had AR, and 3 (3.8%) had efficacy failure. No graft loss or deaths were reported. No new safety signals were identified. Drug‐related treatment‐emergent adverse events occurred in 28 patients (35.4%); most were mild, and all resolved. This study suggests that IR‐T to PR‐T conversion is effective and well tolerated over 1 year in pediatric transplant recipients and highlights the importance of therapeutic drug monitoring to maintain target tacrolimus trough levels.

Abstract
There is debate in the literature regarding management of patients with sickle cell trait (SCT) undergoing cardiac surgery, since it is recognized that cardiopulmonary bypass presents many precipitating risk factors for a sickling crisis. Despite this, many report successful outcomes without any modification to perioperative management. A 49-year-old woman with SCT (HbS 38%) with postpartum cardiomyopathy underwent cardiac transplantation. The patient was cooled to 34.0°C and retrograde cold blood cardioplegia was infused continuously. The cold ischemic time was 219 minutes and warm ischemic time 46 minutes. After weaning from bypass, she developed global cardiac dysfunction requiring veno-arterial extracorporeal membrane oxygenation. The circuit suddenly stopped, requiring emergency reinstitution of bypass; the circuit had clotted. Transesophageal-echocardiogram revealed thrombus within the left atrium and ventricle. There was no recovery of cardiac function and the patient developed multiorgan failure. At postmortem there was extensive myocardial infarction with evidence of widespread catastrophic intravascular red-cell sickling. This case highlights the danger of complacency in patients with SCT, offering a learning opportunity for the cardiothoracic community to highlight the most serious complication that can occur in this group of patients. We have learned that SCT and cardiac surgery is not a benign combination.

Abstract
Human immunodeficiency virus-positive (HIV+) patients are not routinely offered heart transplantation (HT) due to lack of adequate outcomes data. Between January 2004 and March 2017, we identified 41 adult (≥18 years) HT recipients with known HIV+ serostatus at the time of transplant in UNOS and evaluated post-HT outcomes. Overall, Kaplan-Meier (KM) estimates of survival at 1 and 5 years were 85.9% and 77.3%, respectively, with no significant difference in bridge-to-transplant ventricular-assist device (BTT-VAD, n = 22) and no-BTT-VAD (n = 19). KM estimates of cardiac allograft vasculopathy (CAV) and malignancy at 5 years were 32% and 19%, respectively. Using propensity scores, 41 HIV+ HT recipients were matched to 41 HIV- HT recipients for idiopathic dilated-cardiomyopathy; and there was no significant difference in post-HT survival up to 5 years. Furthermore, only 24 centers in the United States had performed HIV+ HT during the study period, indicating that >80% of HT centers in the United States had not performed any HIV+ HT. In a cohort representative of the current status of HIV+ HTs in the United States, we found that the posttransplant survival was excellent and rates of CAV and malignancy were comparable to the overall HT population. These results should encourage greater number of centers to offer HT to suitable HIV+ candidates and help reduce unequal access to HT for HIV+ patients.

Abstract
Clinical Trials in Organ Transplantation-18 (CTOT-18) is a follow-up analysis of the 200-subject multicenter heart transplant CTOT-05 cohort. CTOT-18 aimed to identify clinical, epidemiologic, and biologic markers associated with adverse clinical events past 1 year posttransplantation. We examined various candidate biomarkers including serum antibodies, angiogenic proteins, blood gene expression profiles, and T cell alloreactivity. The composite endpoint (CE) included death, retransplantation, coronary stent, myocardial infarction, and cardiac allograft vasculopathy. The mean follow-up was 4.5 ± SD 1.1 years. Subjects with serum anti-cardiac myosin (CM) antibody detected at transplantation and at 12 months had a higher risk of meeting the CE compared to those without anti-CM antibody (hazard ratio [HR] = 2.9, P = .046). Plasma VEGF-A and VEGF-C levels pretransplant were associated with CE (odds ratio [OR] = 13.24, P = .029; and OR = 0.13, P = .037, respectively). Early intravascular ultrasound findings or other candidate biomarkers were not associated with the study outcomes. In conclusion, anti-CM antibody and plasma levels of VEGF-A and VEGF-C were associated with an increased risk of adverse events. Although this multicenter report supports further evaluation of the mechanisms through which anti-CM antibody and plasma angiogenesis proteins lead to allograft injury, we could not identify additional markers of adverse events or potential novel therapeutic targets.

Abstract
Primary graft failure (PGF) after heart transplantation (HT) is a devastating and unexpected event characterized by failure of the graft to adequately support recipient circulation necessitating high doses of vasopressors and inotropes and/or temporary mechanical circulatory support. Although it represents an increasingly common event in the current era, there remains a high degree of variability in prevalence, reported risk factors, and approach to this clinical entity. The purpose of the current review is to highlight preoperative considerations including known incidence and risk factors, perioperative issues involving the identification and management of PGF, and postoperative decisions related to weaning of mechanical circulatory support and titration of immunosuppressive therapy. Lastly, we highlight future directions in PGF research, involving basic and translational research, that have the potential to uncover novel strategies of risk stratification and treatment. CASE: Our patient is a 53-year-old man with end-stage non-ischemic dilated cardiomyopathy complicated by ventricular tachycardia (VT), post-capillary pulmonary hypertension, and renal insufficiency. After progressing to NYHA Class IV symptoms, he underwent implantation of a durable left ventricular assist device (LVAD) as bridge to transplant (BTT). On device support, he developed recurrent VT resulting in multiple defibrillator discharges and hospital admission for intravenous anti-arrhythmic therapy. He is subsequently upgraded to a higher status on the waiting list. A suitable donor is identified, with an appropriate predicted heart mass and an anticipated ischemic time of <4 hours. He is taken to the operating room, where at the time of anesthesia induction he develops vasodilatory shock, requiring high-dose vasopressors, and cardiopulmonary bypass (CPB) support for dissection. After surgical anastomosis, cross clamp removal and reperfusion, graft function is extremely poor, there is significant bradycardia requiring pacing, and the patient is unable to be weaned successfully from CPB. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is initiated, and the patient is transferred to the intensive care unit. Retrospective flow crossmatch is negative. This patient is suffering from severe primary graft failure.

Abstract
Human leukocyte antigen-G (HLA-G) expression is modulated by immunosuppressant use and is associated with lower incidence of graft rejection and cardiac allograft vasculopathy (CAV). We examined whether everolimus induces HLA-G expression and inhibits human coronary artery smooth muscle cell (HCASMC) proliferation, a critical event in CAV. Also, we examined whether TNFα-stimulated neutrophil adhesion is inhibited by HLA-G on human coronary artery endothelial cells (HCAECs). HLA-G expression in HCASMCs following everolimus treatment was determined by western-blot densitometric analysis. HCASMCs proliferation following incubation with recombinant HLA-G was determined by automated cell counter detecting 2-10 µm particles. Assessment of recombinant HLA-G on neutrophil adhesion to HCAECs in response to TNF-α induced-injury was determined by nonstatic adhesion assays. HLA-G expression was upregulated in HCASMCs following everolimus exposure (1000 ng/ml; P < .05). HLA-G (500, 1000 ng/ml; both P < .05) reduced HCASMC proliferation and inhibited TNFα-stimulated neutrophil adhesion to endothelial cells at all concentrations (0.1-1 ng/ml; all P < .001). Our study reveals novel regulation of HLA-G by everolimus, by demonstrating HLA-G upregulation and subsequent inhibition of HCASMC proliferation. HLA-G is a potent inhibitor of neutrophil adhesion to HCAECs. Findings support HLA-G's importance and potential use in heart transplantation for preventative therapy or as a marker to identify patients at high risk for developing CAV.

Abstract
Eosinophilic granulomatosis with polyangitis (EGPA), previously referred to as Churg-Strauss syndrome, is a necrotizing small vessel vasculitis associated with eosinophilic infiltrates and extravascular granulomas. We report a case of a Caucasian woman successfully bridged to heart transplantation with a continuous flow left ventricular assist device (LVAD) who survived recurrence of EGPA in the allograft.

Abstract
Changes in heart transplantation (HT) donor and recipient demographics may influence the incidence of primary graft dysfunction (PGD). We conducted a retrospective study to evaluate PGD incidence, trends, and associated risk factors by analyzing consecutive adult patients who underwent HT between January 2009 and December 2014 at our institution. Patients were categorized as having PGD using the International Society for Heart & Lung Transplantation (ISHLT)-defined criteria. Variables, including clinical and demographic characteristics of donors and recipients, were selected to assess their independent association with PGD. A time-trend analysis was performed over the study period. Three-hundred seventeen patients met inclusion criteria. Left ventricular PGD, right ventricular PGD, or both, were observed in 99 patients (31%). Risk factors independently associated with PGD included ischemic time, recipient African American race, and recipient amiodarone treatment. Over the study period, there was no change in the PGD incidence; however, there was an increase in the recipient pretransplantation use of amiodarone. The rate of 30-day mortality was significantly elevated in those with PGD versus those without PGD (6.06% vs 0.92%, P = .01). Despite recent advancements, incidence of PGD remains high. Understanding associated risk factors may allow for implementation of targeted therapeutic interventions.
