BACKGROUNDThe Advanced Cardiac Therapies Improving Outcomes Network (ACTION) began in 2018 as a collaborative learning health system committed to improving outcomes in pediatric heart failure, including children and adults with congenital heart disease, supported with ventricular assist devices (VADs). This report describes patient and device characteristics, and outcomes through 1-year post-implant.METHODSThe ACTION VAD registry report was created from data submitted to the ACTION learning network from April 2018-June 2023. It includes 1,430 devices implanted in 1,220 pediatric patients (<18) from 57 sites across North America.RESULTSMales comprised 55% of the registry patients. The median age was 3.7 years with a median implant weight of 13.6 kg; 36% of the cohort was <10 kg. Nearly 40% of patients had a primary diagnosis of congenital heart disease (CHD). Patients with CHD represented 26% of VAD implants in 2018 which increased to 42% in 2023 (p=0.03). At implant, 25% of patients were supported with ECMO, 4.9% with dialysis, and 54% were mechanically ventilated. Paracorporeal pulsatile pumps comprised 40.2% of implants, followed in incidence by paracorporeal continuous flow (28.5%), and implantable continuous flow (24.1%). The number of patients in the VAD Registry patients increased from 102 in 2018 to 256 in 2022, partly reflecting increased center participation in ACTION. Overall survival on support at 1 year was 79.2%, and the incidence of stroke was 13.7%. Infants demonstrated the poorest outcomes, with a 1-year survival of 72.9% and a higher incidence of stroke (20.8%).CONCLUSIONThe five-year ACTION VAD experience highlights the growing collaboration in the pediatric VAD community and changes in clinical practice. More work is needed to improve survival and limit adverse outcomes, especially in younger patients.
先进心脏治疗改善结局网络(ACTION)于2018年启动,作为一个协作学习卫生系统,致力于改善儿童心力衰竭的结局,包括患有先天性心脏病的儿童和成人,并支持心室辅助装置(vad)。本报告描述了患者和器械的特点,以及植入后1年的结果。方法根据2018年4月至2023年6月提交给ACTION学习网络的数据创建ACTION VAD注册表报告。它包括在北美57个地点的1,220名儿科患者(<18岁)中植入1,430个设备。结果男性占登记患者的55%。中位年龄为3.7岁,中位种植体重量为13.6 kg;36%的队列体重<10公斤。近40%的患者最初诊断为先天性心脏病(CHD)。2018年,冠心病患者占VAD植入物的26%,到2023年增加到42% (p=0.03)。植入时,25%的患者采用ECMO, 4.9%采用透析,54%采用机械通气。体外脉动泵占植入物的40.2%,其次是体外连续流(28.5%)和植入物连续流(24.1%)。VAD注册患者的数量从2018年的102例增加到2022年的256例,部分反映了中心参与ACTION的增加。1年的总生存率为79.2%,卒中发生率为13.7%。婴儿的预后最差,1年生存率为72.9%,卒中发生率较高(20.8%)。结论:ACTION VAD的5年经验凸显了儿科VAD社区合作的增长和临床实践的变化。需要更多的工作来提高生存率和限制不良后果,特别是在年轻患者中。

PURPOSEThe new rescue kidney policy in the United States was implemented in June 2023. To estimate its potential impact, we investigated a historic cohort of heart transplant (HT) recipients who would have been eligible for a kidney-after-heart transplant under this policy.METHODSAdult heart-only recipients from 1/1/2000 to 3/31/2023 in the United Network for Organ Sharing database were categorized by retroactively applying eligibility criteria from the new policy: eGFR≤20mL/min, CrCl≤20mL/min, or dialysis 60-365 days post-HT. We evaluated outcomes of eligible recipients.RESULTSOf 45,833 HT recipients, 840 (1.8%) were eligible for a rescue kidney. Eligible recipients had higher median age (58 vs. 56 years, p<0.001) and serum creatinine (1.4 vs. 1.2, p<0.001), and were more likely to be status 1A in the pre-2018 allocation era (63.4% vs. 51.9%, p<0.001) and status 1 in the post-2018 allocation era (13.9% vs. 9.1%, p=0.003). Survival at 1 year conditional on 60-day survival was worse for eligible recipients (50.8% vs. 96.3%; HR 17.6 [95%CI: 15.8-19.6], p<0.001). Post-HT, 607 (72.3%) eligible recipients were never listed for kidney transplant (KT), of whom 486 (80.1%) died with a median time-to-death of 8.8 months. Among the 233 (27.7%) recipients listed for KT, 65 (27.9%) died/deteriorated on the waitlist and 99 (42.5%) received a KT (median 38.4 months post-HT).CONCLUSIONSHalf of recipients eligible for a rescue kidney did not survive to 1 year post-HT, and >70% were never listed for KT. The effects of the new policy on mitigating mortality in this challenging population will be paramount.
目的:美国新的抢救肾政策于2023年6月实施。为了评估其潜在影响,我们调查了一组历史悠久的心脏移植(HT)受者,他们在该政策下有资格进行心脏后肾移植。方法:从2000年1月1日至2023年3月31日,在美国器官共享网络数据库中,通过追溯应用新政策的资格标准进行分类:eGFR≤20mL/min, CrCl≤20mL/min,或ht后60-365天透析。我们评估了符合条件的接受者的结果。结果45,833名HT受者中,840名(1.8%)符合救援肾的条件。符合条件的接受者的中位年龄较高(58岁vs 56岁),其中70%从未列入KT。新政策对降低这一具有挑战性的人口的死亡率的影响将是至关重要的。

BACKGROUNDRV reserve has been linked to exercise capacity and prognosis in cardiopulmonary diseases. However, evidence in this setting is limited, due to the complex shape and load dependency of the RV. We sought to study right ventricular (RV) adaptation to exercise by simultaneous three-dimensional echocardiography (3DE) and right heart catheterization (RHC).METHODSPatients with heart failure with preserved ejection fraction (HFpEF) or pulmonary vascular disease (PVD) underwent simultaneous supine rest/exercise RHC-3DE. They were subdivided based on RV ejection fraction (EF) changes: 1)exhausted RV reserve, RVEF-; 2)preserved RV reserve, RVEF+.RESULTSSixty percent of patients were RVEF-. Distribution of HFpEF/PVD, as well as RV volumes and RVEF at rest were similar in the two groups. Hemodynamic metrics of RV afterload, as well as their exercise-induced changes, were similar in the two groups. During exercise, RV end-diastolic volume increased more in RVEF- than in RVEF+ (29±29 vs 7±25 mL,p<0.05). RV end-systolic volume increased by 21[12;31]mL in RVEF- and decreased by 8[-15;1]mL in RVEF+ (p<0.001). RV-pulmonary artery coupling was lower in RVEF- at peak exercise(p<0.05). Peak RVEF was associated with left ventricular preload (R2=0.14,p=0.011). Cardiac output increased less in RVEF- than in RVEF+ (+2.3±2.0 vs +4.0±2.4 L/min,p<0.05). Peak RVEF was associated with oxygen consumption(p<0.01).CONCLUSIONSExhausted RV reserve, as evaluated by 3DE, was frequent in HFpEF and PVD, was relatively independent from classical afterload parameters, was associated with RV-pulmonary artery decoupling, RV dilation, enhanced ventricular interdependence, and cardiac limitation to exercise. Intrinsic RV dysfunction may contribute to exhausted RV reserve.
背景:drv储备与心肺疾病患者的运动能力和预后有关。然而,由于RV复杂的形状和载荷依赖性,在这种情况下的证据是有限的。我们试图通过三维超声心动图(3DE)和右心导管(RHC)同时研究右心室(RV)对运动的适应性。方法心力衰竭伴保射血分数(HFpEF)或肺血管疾病(PVD)患者同时进行仰卧休息/运动RHC-3DE。根据右心室射血分数(EF)的变化将其细分为:1)用尽右心室储备,RVEF-;2)保留的RV储备,RVEF+。结果60%的患者为RVEF-。两组患者的HFpEF/PVD分布、静息时RV体积和RVEF相似。两组右心室后负荷的血流动力学指标及其运动引起的变化相似。运动时,RVEF-组右心室舒张末期容积比RVEF+组增大(29±29 vs 7±25 mL,p<0.05)。RVEF-组右心室收缩末容积增加21[12;31]mL, RVEF+组右心室收缩末容积减少8[-15;1]mL (p<0.001)。运动高峰时RVEF-组rv -肺动脉耦合较低(p<0.05)。RVEF峰值与左心室预负荷相关(R2=0.14,p=0.011)。RVEF-组心输出量的增加小于RVEF+组(+2.3±2.0 vs +4.0±2.4 L/min,p<0.05)。RVEF峰值与耗氧量相关(p<0.01)。结论3DE评价的右心室储备衰竭在HFpEF和PVD中较为常见,与经典后负荷参数相对独立,与右心室-肺动脉解耦、右心室扩张、心室相互依赖性增强和心脏对运动的限制有关。内源性右心室功能障碍可能导致右心室储备衰竭。

Peak RVEF was associated with left ventricular preload (R2=0.14,p=0.011). Cardiac output increased less in RVEF- than in RVEF+ (+2.3±2.0 vs +4.0±2.4 L/min,p<0.05). Peak RVEF was associated with oxygen consumption(p<0.01).CONCLUSIONSExhausted RV reserve, as evaluated by 3DE, was frequent in HFpEF and PVD, was relatively independent from classical afterload parameters, was associated with RV-pulmonary artery decoupling, RV dilation, enhanced ventricular interdependence, and cardiac limitation to exercise. Intrinsic RV dysfunction may contribute to exhausted RV reserve.","PeriodicalId":22654,"journal":{"name":"The Journal of Heart and Lung Transplantation","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142887603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heart transplantation remains a critical therapy for patients with end-stage heart failure, offering incremental survival and improved quality of life. One of the key components behind the success of heart transplantation is the condition and preservation of the donor heart. In this review, we provide a comprehensive overview of ischemic reperfusion injury, risk factors associated with primary graft dysfunction, current use of various preservation solutions for organ procurement and recent advancements in donor heart procurement technologies. This State-of-the-Art review will explore factors associated with bringing the "ideal" donor heart to the operating room in the contemporary era.
心脏移植仍然是终末期心力衰竭患者的关键治疗方法,可以增加生存时间并改善生活质量。心脏移植成功的关键因素之一是供体心脏的状况和保存。在这篇综述中,我们提供了缺血性再灌注损伤的全面概述,与原发性移植物功能障碍相关的危险因素,目前各种器官获取保存解决方案的使用以及供体心脏获取技术的最新进展。这篇最新的综述将探讨在当代将“理想”供体心脏带到手术室的相关因素。
