Abstract
Life expectancy of patients with a durable, continuous-flow left ventricular assist device (CF-LVAD) continues to increase. Despite significant improvements in the delivery of care for patients with these devices, hemocompatability-related adverse events (HRAEs) are still a concern and contribute to significant morbility and mortality when they occur. As such, dissemination of current best evidence and practices is of critical importance. This ISHLT Consensus Statement is a summative assessment of the current literature on prevention and management of HRAEs through optimal management of oral anticoagulant and antiplatelet medications, parenteral anticoagulant medications, management of patients at high risk for HRAEs and those experiencing thrombotic or bleeding events, and device management outside of antithrombotic medications. This document is intended to assist clinicians caring for patients with a CF-LVAD provide the best care possible with respect to prevention and management of these events.

Abstract
Heart failure remains a major global burden regarding patients' morbidity and mortality and health system organization, logistics, and costs. Despite continual advances in pharmacological and resynchronization device therapy, it is currently well accepted that heart transplantation and mechanical circulatory support represent a cornerstone in the management of advanced forms of this disease, with the latter becoming an increasingly accepted treatment modality due to the ongoing shortage of available donor hearts in an ever-increasing pool of patients. Mechanical circulatory support strategies have seen tremendous advances in recent years, especially in terms of pump technology improvements, indication for use, surgical techniques for device implantation, exchange and explantation, and postoperative patient management, but not in the field of treatment of critically ill patients and those undergoing cardiac arrest. This contemporary review aims to summarize the collected knowledge of this topic with an emphasis on complications in patients with left ventricular assist devices, their treatment, and establishing a clear-cut algorithm and the latest recommendations regarding out-of-hospital or emergency department management of cardiac arrest in this patient population.

[PMID: 35098565 DOI: 10.1111/bcp.15251] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Revised: 11/20/2021] [Accepted: 01/14/2022] [Indexed: 12/01/2022] Open
Abstract
AIMS Unfractionated heparin (UFH) has been the primary anticoagulant of choice on extracorporeal membrane oxygenation (ECMO). However, it is debatable whether bivalirudin (BIV), a direct thrombin inhibitor, may be considered a better alternative anticoagulant option. METHODS We searched Embase, Pubmed, Cochrane library, Clinicaltrials.gov, CNKI, and Wanfang databases up to June 15, 2021. Randomized controlled trials (RCTs) and observational studies were considered eligible for inclusion. Random-effects meta-analyses, including subgroup analyses, were conducted. RESULTS A total of 9 studies containing 994 patients were enrolled. All articles were retrospective cohort studies. Compared with UFH, BIV was associated with lower risks of major bleeding (risk ratio [RR]: 0.32, 95% confidence interval [CI] 0.22-0.49), ECMO in-circuit thrombosis (RR: 0.57, 95% CI 0.43-0.74), stroke (RR: 0.52, 95% CI 0.29-0.95), in-hospital mortality (RR: 0.82, 95% CI 0.69-0.99) and higher rates of survival to ECMO decannulation (RR: 1.18, 95% CI 1.03-1.34). Pooled risk estimates did not show a significant association with clinical thrombotic events (RR: 0.69, 95% CI 0.45-1.07). Moreover, BIV was associated with a lower risk of ECMO in-circuit thrombosis and in-hospital mortality in the adult subgroup but not in the pediatric subgroup. However, leave-one-out sensitivity analyses indicated that the results of stroke, survival to ECMO decannulation and in-hospital mortality should be interpreted with caution. CONCLUSIONS BIV appears to be a potential alternative to UFH in pediatric and adult patients requiring ECMO.

Abstract
A 55-year-old woman who had received an implantable left ventricular assist device 3 months earlier presented with dyspnea and a low-flow alarm of the device. Computed tomography and log-file analysis of the device system suggested inflow cannula obstruction. Since the patient had cardiogenic shock due to pump failure, venoarterial extracorporeal membrane oxygenation (ECMO) was initiated. With ECMO, surgical exchange of the pump was considered. However, the obstruction spontaneously resolved without surgical intervention. It turned out that an obstructive thrombus was washed out by rebooting the pump. Moreover, the thrombus was embolized in the patient’s left subclavian artery. The patient underwent heart transplantation 4 months after the pump obstruction accident and continued to do well.

Abstract
Encountering a child with congenital heart disease after surgical palliation in the emergency department, specifically the single-ventricle or ventricular assist device, without a basic familiarity of these surgeries can be extremely anxiety provoking. Knowing what common conditions or complications may cause these children to visit the emergency department and how to stabilize will improve the chance for survival and is the premise for this article, regardless of practice setting.

Using existing technology better: Improving outcomes with the HeartWare left ventricular assist device. Int J Cardiol 2021; 331:35-39. [PMID: 33529660 DOI: 10.1016/j.ijcard.2021.01.039] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 01/20/2021] [Accepted: 01/22/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND The HeartWare left ventricular assist device has been in use for over 12 years. We sought to determine how outcomes at our centre have improved over time. METHODS Review of electronic hospital records at the Freeman Hospital, Newcastle upon Tyne, United Kingdom. RESULTS A total of 255 first time adult implants were divided into 2 eras: Era 1: 2009-2015 (N = 154) and Era 2: 2016-2020 (N = 101). We prospectively aimed to avoid higher risk Intermacs Classifications in Era 2, which resulted in significant changes in Intermacs class to lower risk in Era 2 (P < 0.001). There was a significant improvement in survival in Era 2, with 1 year survival increasing from 70 to 80% (P < 0.05). This was particularly associated with lower 30 day mortality in Era 2 (1.7 ± 2.3 vs 15.5 ± 7%, P < 0.005). This was associated with better right ventricular function in Era 2, and there was a trend to more temporary right ventricular assist devices used in Era 2 (28 ± 13 vs 12 ± 14%, P = 0.06). Deaths from intracranial haemorrhage, sepsis and right heart failure were unchanged between eras, though there was a trend towards less deaths in Era 2 from combined thromboses deaths (stroke and device thrombosis; 3.3 ± 5.4 vs 11.1 ± 7.4%, P = 0.07). CONCLUSIONS Better patient selection in association with more use of temporary right ventricular assist support has resulted in a significant improvement in survival. Intracranial haemorrhage, sepsis and right heart failure remain significant problems.
