RESUMO

INTRODUCTION: Pediatric heart transplant patients are routinely followed in dermatology clinics due to elevated risk of cutaneous malignancy. However, transplant patients may experience other, non-cancer-related dermatologic conditions including skin infections, inflammatory diseases, and drug eruptions that can cause significant medical and psychosocial comorbidity. METHODS: A retrospective chart review of all pediatric heart transplant patients at Mayo Clinic Children's Center in Rochester, MN, was performed to determine the prevalence and spectrum of non-cancer dermatologic conditions. Statistical analysis was conducted to look for associations between episodes of rejection and skin condition development. RESULTS: Of the 65 patients who received heart transplants under the age of 18 and were followed at Mayo Clinic, 69% (N = 45) were diagnosed with at least one skin condition between transplant and the time of most recent follow-up. Sixty-two percent (N = 40) of patients were diagnosed with an inflammatory skin condition (most commonly acne and atopic dermatitis), 45% (N = 29) with an infectious skin condition (most commonly warts and dermatophyte infection), and 32% (N = 21) with a drug eruption (most commonly unspecified rash and urticaria). No association was found between presence of skin disease and number of rejection episodes. CONCLUSIONS: Non-cancer dermatologic conditions are prevalent within pediatric heart transplant recipients and may directly impact their medical needs and quality of life. Dermatologist involvement in the care of post-transplant pediatric patients is important, not only for cancer screening but also for diagnosis and treatment of common infectious and inflammatory skin conditions.

RESUMO

BACKGROUND: Paediatric studies have shown serum N-terminal pro b-type natriuretic peptide levels to be a valuable tool in the surveillance of myocardial function and an early biomarker for rejection in transplant patients. The correlation between low mean right atrial pressure and increased inferior vena cava collapsibility index is well studied in adults. Our study aims to assess correlation between non-invasive measurements (serum N-terminal pro b-type natriuretic peptide, inferior vena cava dimensions collapsibility, tricuspid regurgitation, and left ventricular remodelling index to invasive mean right atrial pressure in paediatric heart transplant patients). METHODS: A single centre, retrospective chart review of the paediatric transplant patients from 0 to 21 years of age was performed between 2015 and 2017. Thirty-nine patients had complete data which includes cardiac catheterisation, transthoracic echocardiogram, and serum N-terminal pro b-type natriuretic peptide levels done within a two weeks of interval. RESULTS: A higher inferior vena cava collapsibility index correlated with a lower mean right atrial pressure (r = -0.21, p = 0.04) and a larger inferior vena cava diameter in expiration indexed to body surface area (IVCmax/BSA0.5) correlated with a higher mean right atrial pressure (r = 0.29, p = 0.01). There was a correlation between elevated N-terminal pro b-type natriuretic peptide and inferior vena cava collapsibility index (r = -0.38, p = 0.0001), IVCmax/BSA0.5 (r = 0.25, p = 0.0002), and mean right atrial pressure (r = 0.6, p = 0.0001). CONCLUSION: Serum N-terminal pro b-type natriuretic peptide levels correlated to non-invasive measurements (inferior vena cava collapsibility index and IVCmax/BSA0.5) and to the invasive mean right atrial pressure. Non-invasive (IVC-CI IVCmax/BSA0.5) correlates with elevated mean right atrial pressure in this population. Together, these may serve as a reliable surveillance tool in assessing right heart filling pressures and cardiac function within the paediatric heart transplant patient.

RESUMO

BACKGROUND: Management of infants with pulmonary atresia/intact ventricular septum (PA/IVS) is variable. Because of higher mortality in more severe forms, heart transplant (HT) is an acceptable approach, but waitlist and post-transplant outcomes are unclear. This study compared outcomes of infants with PA/IVS vs. other single ventricle (SV) anatomies listed for HT. METHODS: Data from the Pediatric Heart Transplant Society (1993-2018) were analyzed for survival and risk factors for mortality. RESULTS: Of 1617 SV infants, 300 had PA/IVS (19%) and 1317 had other SV (81%). Overall, 1-, 5-, and 10-year survival was higher among PA/IVS (74%, 65%, 61%) versus other SV infants (62%, 54%, 50%, p = .004). While waitlist mortality was similar between groups (p = .09), PA/IVS was an independent predictor of improved waitlist survival (HR 0.68, p = .03), and PA/IVS infants had higher incidence of waitlist removal (8% vs. 5.5%, p = .03), most commonly for being "too well." Post-transplant survival was superior among PA/IVS versus other SV infants (1- and 5-year survival 93% and 81% vs. 80% and 71%, p < .0001). Risk factors for PA/IVS waitlist mortality (2008-2018) included extracorporeal membrane oxygenation and mechanical ventilation. Prior aortopulmonary (AP) shunt among PA/IVS infants was associated with improved waitlist survival. CONCLUSIONS: Overall survival among PA/IVS infants listed for HT exceeds that of other SV infants with PA/IVS identified as an independent predictor of improved waitlist and post-transplant survival. Prior AP shunt among listed PA/IVS infants was associated with improved waitlist outcomes, though, which may reflect a listing selection bias.

RESUMO

BACKGROUND: Obesity and dyslipidemia afflict children of all ages. We explored the prevalence of obesity and dyslipidemia in pediatric heart transplant (HT) recipients and its effects on cardiac allograft vasculopathy (CAV) and survival. METHODS: This study included primary HT recipients (≤18 years) transplanted between 01/1996 and 12/2018 included in the Pediatric Heart Transplant Society database. Obesity was categorized according to WHO/CDC guidelines and dyslipidemia according to the National Cholesterol Education Program. Kaplan-Meier analyses for CAV and graft loss stratified for BMI and lipid panels were generated and risk factors identified using multivariate analyses. RESULTS: Among 6291 HT patients (median age [range] at HT = 4.3 [0.6-12.8] years; 45% Female; 68% White), 56% had a normal BMI at HT. Obese patients at HT had an increased risk for graft loss (HR 1.19, 95% CI 1.01-1.4, p = .04). Poor total cholesterol (TC), LDL-C, and TG were associated with the risk of both CAV (HR 1.79, p < .0001; HR 1.65, p = .0015; HR 1.53, p < .0001, respectively) and graft loss (HR 1.58, p = .0008; HR 1.22, p = .04; HR 1.43, p = .0007, respectively). CONCLUSIONS: Pediatric patients who are obese at the time of HT and dyslipidemic at 1 year post-HT are at an increased risk for CAV and graft loss. Preventative interventions may reduce morbidity and mortality among this cohort.

RESUMO

Capillary malformation-arteriovenous malformation (CM-AVM) syndrome is an autosomal dominant condition characterized by multifocal, noncontiguous pink patches on the skin that often have a surrounding pale halo. In some cases, an association with a fast flow, arteriovenous malformation (AVM) can be identified. Here, we describe a case report of a 16-year-old woman with CM-AVM syndrome and significant cardiac compromise successfully treated with trametinib, a mitogen-activated protein kinase (MEK) inhibitor.

RESUMO

BACKGROUND: Fontan-associated liver disease (FALD) uniformly affects patients with long-term Fontan physiology. The effect of isolated heart transplant (HT) on the course of FALD post-HT is not well understood. METHODS: We evaluated serial liver imaging pre- and post-HT to assess liver changes over time in a single-center retrospective analysis of Fontan HT recipients who had pre- and ≥1-year post-HT liver imaging. Available patient demographic and clinical data were reviewed, including available liver biopsy results. RESULTS: Serial liver imaging was available in 19 patients with a median age at HT of 12 years (range 3-23), the median age from Fontan to HT of 5.7 years (range 0.8-16), and the median time from imaging to follow up of 27 months (range 12-136 months). Pre-HT liver imaging was classified as follows: normal (n=1), congested (n=9), fibrotic (n=7), and cirrhotic (n=2). The majority of transplanted patients (15/19) had improvement in their post-HT liver imaging, including 13 patients with initially abnormal imaging pre-HT having normal liver imaging at follow-up. One patient had persistent cirrhosis at 26-month follow-up, one patient had unchanged fibrosis at 18-month follow-up, and one patient progressed from fibrosis pre-HT to cirrhosis post-HT at 136 months. No patients had overt isolated liver failure during pre- or post-HT follow-up. Liver biopsy did not consistently correlate with imaging findings. CONCLUSIONS: Post-HT liver imaging evaluation in Fontan patients reveals heterogeneous liver outcomes. These results not only provide evidence for the improvement of FALD post-HT but also show the need for serial liver imaging follow-up post-HT.

RESUMO

Intracoronary wave intensity analysis in hypertrophic cardiomyopathy has shown a large backward compression wave due to compressive deformation of the intramyocardial coronary arteries in systole. The authors describe the angiographic evidence of this backward compression wave, which has not been described in this physiological context and can be a marker of poor prognosis.

RESUMO

INTRODUCTION: Pediatric patients with cardiomyopathies are at risk for sudden death and may need implantable cardioverter defibrillators (ICD's), but given their small size and duration of use, children are at increased risk for complications associated with ICD use. The subcutaneous ICD presents a favorable option for children without pacing indications. Unfortunately, initial pediatric studies have demonstrated a high complication rate, likely due to the 3-incision technique employed. MATERIAL AND METHODS: Patients with ICD but no pacing indication were retrospectively reviewed after implantation of subcutaneous ICD via the two-incision technique. In half of the patients, 10-J impedance test was also performed to compare with impedance obtained after defibrillation threshold testing with 65-J. RESULTS: Twelve patients were included. The median age was 14 years (range 10-16 years) with eight males included (72.7%). The median weight was 55 kg (range 29 kg-75.1 kg). Follow-up had a median of 11.5 months (range 2-27 months). The median body mass index was 18.4 kg/m squared (range 15.5-27.9 kg/m squared). One patient suffered a minor complication after tearing off the incisional adhesive strips early and required a non-invasive repair in clinic. Shock impedance had a median of 55 J (range 48-68 J). There was one appropriate shock/charge and no inappropriate shocks during follow-up. CONCLUSION: The two-incision, intermuscular technique appears to have a lower acute complication rate than prior reports, in our cohort of 12 pediatric patients.

RESUMO

This scientific statement presents considerations for clinical management regarding the assessment and risk reduction of select pediatric populations at high risk for premature cardiovascular disease, including acquired arteriosclerosis or atherosclerosis. For each topic, the evidence for accelerated acquired coronary artery disease and stroke in childhood and adolescence and the evidence for benefit of interventions in youth will be reviewed. Children and adolescents may be at higher risk for cardiovascular disease because of significant atherosclerotic or arteriosclerotic risk factors, high-risk conditions that promote atherosclerosis, or coronary artery or other cardiac or vascular abnormalities that make the individual more vulnerable to the adverse effects of traditional cardiovascular risk factors. Existing scientific statements and guidelines will be referenced when applicable, and suggestions for risk identification and reduction specific to each setting will be described. This statement is directed toward pediatric cardiologists, primary care providers, and subspecialists who provide clinical care for these young patients. The focus will be on management and justification for management, minimizing information on pathophysiology and epidemiology.

RESUMO

BACKGROUND: The use of ventricular assist devices (VADs) in children with heart failure may be of particular benefit to those with accompanying renal failure, as improved renal function is seen in some, but not all recipients. We hypothesized that persistent renal dysfunction at 7 days and/or 1 month after VAD implantation would predict chronic kidney disease (CKD) 1 year after heart transplantation (HT). METHODS: Linkage analysis of all VAD patients enrolled in both the PEDIMACS and PHTS registries between 2012 and 2016. Persistent acute kidney injury (P-AKI), defined as a serum creatinine ≥1.5× baseline, was assessed at post-implant day 7. Estimated glomerular filtration rate (eGFR) was determined at implant, 30 days thereafter, and 12 months post-HT. Pre-implant eGFR, eGFR normalization (to ≥90 mL/min/1.73 m2 ), and P-AKI were used to predict post-HT CKD (eGFR <90 mL/min/1.73 m2 ). RESULTS: The mean implant eGFR was 85.4 ± 46.5 mL/min/1.73 m2 . P-AKI was present in 19/188 (10%). Mean eGFR at 1 month post-VAD implant was 131.1 ± 62.1 mL/min/1.73 m2 , significantly increased above baseline (P < 0.001). At 1 year post-HT (n = 133), 60 (45%) had CKD. Lower pre-implant eGFR was associated with post-HT CKD (OR 0.99, CI: 0.97-0.99, P = 0.005); P-AKI was not (OR 0.96, CI: 0.3-3.0, P = 0.9). Failure to normalize renal function 30 days after implant was highly associated with CKD at 1 year post-transplant (OR 12.5, CI 2.8-55, P = 0.003). CONCLUSIONS: Renal function improves after VAD implantation. Lower pre-implant eGFR and failure to normalize renal function during the support period are risk factors for CKD development after HT.

RESUMO

NS and related RAS/MAPK pathway (RASopathy) disorders are the leading genetic cause of HCM presenting in infancy. HCM is a major cause of morbidity and mortality in children with Noonan spectrum disorders, especially in the first year of life. Previously, there have been only isolated reports of heart transplantation as a treatment for heart failure in NS. We report on 18 patients with NS disorders who underwent heart transplantation at seven US pediatric heart transplant centers. All patients carried a NS diagnosis: 15 were diagnosed with NS and three with NSML. Sixteen of eighteen patients had comprehensive molecular genetic testing for RAS pathway mutations, with 15 having confirmed pathogenic mutations in PTPN11, RAF1, and RIT1 genes. Medical aspects of transplantation are reported as well as NS-specific medical issues. Twelve of eighteen patients described in this series were surviving at the time of data collection. Three patients died following transplantation prior to discharge from the hospital, and another three died post-discharge. Heart transplantation in NS may be a more frequent occurrence than is evident from the literature or registry data. A mortality rate of 33% is consistent with previous reports of patients with HCM transplanted in infancy and early childhood. Specific considerations may be important in evaluation of this population for heart transplant, including a potentially increased risk for malignancies as well as lymphatic, bleeding, and coagulopathy complications.

RESUMO

We report two patients who underwent cardiac transplantation at a young age and subsequently required a HCT for varied indications. Despite the challenges associated with HCT following cardiac transplant, including need for altered immunosuppression, toxicities related to chemotherapy exposure, and infection risks, both patients are currently alive and well. There is a paucity of such successful cases documented in the literature, and these cases highlight the critical importance of an experienced, multidisciplinary team when caring for this patient population.

RESUMO

HUS is a well-known entity primarily associated with bacterial infection and is characterized by a classic triad of anemia, thrombocytopenia, and kidney injury. Its atypical form has been associated with calcineurin inhibitors and has been extensively discussed in renal transplantation. We present a case of tacrolimus-associated HUS in a pediatric heart transplant recipient, which we believe to be previously unreported in the literature.

RESUMO

BACKGROUND: With congenital heart disease patients increasingly living into adulthood, there is a growing population of adult congenital heart disease (ACHD) patients suffering from heart failure. Limited data exist evaluating heart transplant in this population. METHODS: Retrospective review was performed of ACHD patients undergoing heart transplantation 11/1990-1/2023. Kaplan-Meier, cumulative incidence accounting for competing risk of death, and subgroup analyses comparing those with biventricular (BiV) and univentricular (UniV) physiology were performed. Data are presented as median (interquartile range) or counts (%). RESULTS: 77 patients with a median age of 36 years (27, 45) were identified, including 57 (74%) BiV and 20 (26%) UniV. Preoperatively, UniV patients were more likely to have cirrhosis (9/20 [45.0%] vs 4/57 [7.0%], p<0.001) and protein losing enteropathy (4/20 [20.0%] vs 1/57 [1.8%], p=0.015). Multiorgan transplantation was performed in 23 patients (30%) and more frequently in UniV patients (10 [50%] vs. 13[23%], p=0.04). Operative mortality was 6.5%, 2/20 (10%) among UniV and 2/57 (4%) among BiV patients, p=0.276. Median clinical follow-up was 6.0 (1.4, 13.1) years. Survival tended to be lower among UniV patients compared to BiV patients, particularly within the first year (p=0.09), but was similar for survivors beyond one year. At 5 years, incidence of rejection was 28% (17%, 38%) and coronary allograft vasculopathy was 16% (7%, 24%). CONCLUSIONS: Underlying liver disease and need for heart/liver transplantation were significantly higher among UniV patients. Survival tended to be lower among UniV, particularly within the first year, but was similar for survivors beyond one year.

RESUMO

HTx in neonates is mainstay therapy for those with severe cardiomyopathies and congenital heart disease. Fetal listing for HTx has been proposed as a way to increase the potential window for a donor with outcomes predicted to be similar to the neonatal population. Data from the PHTS, a prospective multicenter study, were used to examine the outcomes of fetuses listed between 1993 and 2009. Four thousand three hundred and sixty-five children were listed for HTx during this period. Fetuses comprised 1% and neonates 19.8% of listed patients. In those patients listed as fetus and transplanted, the median wait time from listing to HTx was 55 days (range 4-255), with a median of 25 days (range 0-233) after birth. By six months post-listing, a higher proportion of fetal listed patients had undergone HTx with a lower waitlist mortality when compared with neonate. There was no significant difference in survival following HTx between the two group (p = 0.4). While the results of this study may be less applicable to current practice due to changes in referrals for fetal listing, they do indicate that fetal listing can be a reasonable option. These results are of particular interest at the present time given the ongoing public discourse on the proposed elimination of fetal listing within UNOS.

RESUMO

BACKGROUND: Cardiac allograft vasculopathy (CAV) remains a leading cause of graft loss in pediatric heart transplant (HTx) recipients. Adult literature suggests that aspirin (ASA) use in the early post-HTx period may reduce the risk of CAV. This study aimed to determine the impact of early ASA use on the development of CAV in pediatric HTx recipients. METHODS: All subjects <17 years of age at time of primary HTx who survived ≥3 years without evidence of CAV were identified for inclusion from the Pediatric Heart Transplant Society database (1996-2019). Early ASA use was defined as ASA started within the first 3 years post-HTx and was classified as continuous or intermittent. Frequency of ASA use was described across centers. Kaplan-Meier method assessed freedom from CAV and overall graft survival. Multiphase parametric hazard analyses and propensity score matched analysis were used to identify independent risk factors. RESULTS: 3,011 patients were included with 387 (13%) receiving continuous ASA, 676 (22%) receiving intermittent ASA, and 1,948 (65%) receiving no ASA. ASA use was highly variable across centers (0%-100%). At baseline patients receiving continuous ASA therapy demonstrated inferior graft survival (p < 0.001) and worse freedom from CAV (p = 0.002), but with lower CAV grades (p = 0.05). In multiphase parametric hazard modeling continuous ASA use was not independently associated with CAV, but remained associated with inferior graft survival. Propensity-matched sub-analysis between continuous and no ASA groups demonstrated no difference in freedom from CAV or overall graft loss. CONCLUSIONS: ASA use varies widely across pediatric HTx centers. Early ASA use did not reduce the risk of CAV or graft loss in pediatric heart transplant recipients.

RESUMO

BACKGROUND: There are no criteria guiding the timing of heart transplant referral for Fontan patients, nor are there any characteristics of those deferred or declined listing reported. This study examines comprehensive transplant evaluations for Fontan patients of all ages, listing decisions, and outcomes to inform referral practices. METHODS: Retrospective review of 63 Fontan patients formally assessed by the advanced heart failure service and presented at Mayo Clinic transplant selection committee meetings (TSM) January 2006 to April 2021. The study is compliant with the Helsinki Congress and Declaration of Istanbul and included no prisoners. Statistical analysis was performed with Wilcoxon Rank Sum and Fisher's Exact tests. RESULTS: Median age at TSM was 26 years (17.5, 36.5). Most were approved (38/63 [60%]); 9 of 63 (14%) were deferred and 16 of 63 (25%) were declined. Approved patients more commonly were <18 years old at TSM (15/38 [40%] vs 1/25 [4%], P = .002) compared with those deferred/declined. Complications of Fontan circulatory failure were less common in approved vs deferred/declined patients: ascites (15/38 [40%] vs 17/25 [68%], P = .039), cirrhosis (16/38 [42%] vs 19/25 [76%], P = .01), and renal insufficiency (6/38 [16%] vs 11/25 [44%], P = .02). Ejection fraction and atrioventricular valve regurgitation did not differ between groups. Pulmonary artery wedge pressure was overall high normal (12 mm Hg [9,16]) but higher in deferred/declined vs approved patients, 14.5 (11, 19) vs 10 (8, 13.5) mm Hg, P = .015. Overall survival was significantly lower in deferred/declined patients (P = .0018). CONCLUSION: Fontan patient referral for heart transplant at younger age and before the onset of end-organ complications is associated with increased approval for transplant listing.

RESUMO

Background Children with Down syndrome (DS) have a high risk of cardiac disease that may prompt consideration for heart transplantation (HTx). However, transplantation in patients with DS is rarely reported. This project aimed to collect and describe waitlist and post- HTx outcomes in children with DS. Methods and Results This is a retrospective case series of children with DS listed for HTx. Pediatric HTx centers were identified by their participation in 2 international registries with centers reporting HTx in a patient with DS providing detailed demographic, medical, surgical, and posttransplant outcome data for analysis. A total of 26 patients with DS were listed for HTx from 1992 to 2020 (median age, 8.5 years; 46% male). High-risk or failed repair of congenital heart disease was the most common indication for transplant (N=18, 69%). A total of 23 (88%) patients survived to transplant. All transplanted patients survived to hospital discharge with a median posttransplant length of stay of 22 days. At a median posttransplant follow-up of 2.8 years, 20 (87%) patients were alive, 2 (9%) developed posttransplant lymphoproliferative disorder, and 8 (35%) were hospitalized for infection within the first year. Waitlist and posttransplant outcomes were similar in patients with and without DS (P=non-significant for all). Conclusions Waitlist and post-HTx outcomes in children with DS selected for transplant listing are comparable to pediatric HTx recipients overall. Given acceptable outcomes, the presence of DS alone should not be considered an absolute contraindication to HTx.

RESUMO

Although major breakthroughs in the field of pediatric cardiology, cardiac surgery, intervention, and overall care improved the outlook of congenital heart disease, Eisenmenger syndrome (ES) is still encountered and remains a complex clinical entity with multisystem involvement, including secondary erythrocytosis, increased thrombotic and bleeding diathesis, high arrhythmogenic risk, progressive heart failure, and premature death. Clearly, care for ES is best delivered in multidisciplinary expert centers. In this review, we discuss the considerable recent progress in understanding the complex pathophysiology of ES, means of prognostication, and improvement in clinical outcomes achieved with pulmonary arterial hypertension-targeted therapies. Additionally, we delineate areas of uncertainty in various aspects of care, discuss gaps in current evidence, and review current status in less privileged countries and propose initiatives to reduce disease burden. Finally, we propose the application of emerging technologies to enhance the delivery and quality of health care related to ES and beyond.

RESUMO

1p36 deletion is the most common terminal deletion syndrome in humans. Herein, we report two cases, a 5-month-old female and a 14.5-year-old female, both with 1p36 deletion and left ventricular non-compaction cardiomyopathy. They presented with severely depressed left ventricle function and underwent heart transplantation with excellent outcomes. Given the incidence of heart defects and cardiomyopathy in 1p36 deletion syndrome, it should be recommended that children with this genetic condition have screening for cardiac disease. These cases add to the current literature by demonstrating the potential therapeutic options for non-compaction in 1p36 deletion syndrome and showed the favorable outcomes.
