Abstract Background The use of mechanical circulatory support (MCS) has markedly increased over the last decade, so have the inter-hospital transfers, with the aim of being able to offer advanced heart failure (AHF) therapies and centralizing patients to tertiary centres. Case summary In this article, we present the first in Europe long-distance air transfer of a patient supported by veno-arterial extracorporeal membrane oxygenator and Impella (ECPELLA), as a bridge to successful heart transplant. In our case report, a foreign young patient with AHF due to familiar cardiomyopathy required multiple MCS devices to achieve cardiovascular stability. After appropriate planning and multidisciplinary discussion, the patient was transferred on MCS to his country of origin via a fixed-wing airplane, in order to be assessed for heart transplantation. During take-off, the Impella flows temporarily dropped and a suction alarm was displayed; however, this rectified without intervention, and the rest of the flight was uneventful. One month after transfer, the patient underwent successful heart transplantation and remained clinically stable during the 12-month follow-up. Discussion Our experience links together the current challenges in the evolving AHF strategies and the increased need for inter-facility cooperation. Both these clinical and logistic challenges appear to lead to possible improved outcomes, after appropriate assessment, training, and accurate planning. Our experience provides useful information on feasibility of long-distance transport of patients supported by ECPELLA in Europe.

Aims We present a single‐centre retrospective experience using oral milrinone in patients with a left ventricular assist device (LVAD) and concurrent refractory right ventricular failure. Methods and results All patients implanted with LVAD between January 2013 and July 2021 from a high‐volume advanced heart failure service were reviewed. Eight patients were initiated on oral milrinone during this period. Oral milrinone was started 1.5 [inter‐quartile range (IQR) 1–2.3] years after LVAD implantation and continued for 1.2 (IQR 0.5–2.8) years. Therapeutic milrinone levels were achieved (232.2 ± 153.4 ng/mL) with 62.4 ± 18% of time within the therapeutic range. Two patients had adverse events (non‐sustained ventricular tachycardia and ventricular fibrillation effectively treated by internal cardioverter defibrillator) but did not require milrinone discontinuation. Four deaths occurred, one after transplant and three from disease progression determined to be unrelated to oral milrinone use. Three patients continue oral milrinone therapy in the community. There was no significant difference found after the initiation of oral milrinone on any of the physiological measures; however, there were trends in reduction of New York Heart Association class from 3.4 ± 0.5 to 3.0 ± 0.8 (P = 0.08), reduction of right atrial/wedge pressure from 0.9 ± 0.3 to 0.5 ± 0.2 (P = 0.08), and improvement of right ventricular stroke work index from 3.8 ± 2 to 5.8 ± 2.7 (P = 0.16). Conclusions Oral milrinone appears safe for long‐term use in the outpatient setting when combined with therapeutic monitoring in this complex medical cohort with limited management options. Further study is needed to ascertain whether this treatment is effective in reducing heart failure symptoms and admissions.

[...]reversing the flow comes with potential risks, particularly in relation to thrombosis and embolization [2,3,4]. [...]a prerequisite in our study was to maintain UFH at a stable level for at least 12 h, with an anti-Xa activity above 0.3 IU/ml. PCRTO allows physicians to provide a steady and well controlled retrograde flow, challenging the RV whilst reducing the LV afterload. [...]during PCRTO the blood is oxygenated solely by the patient’s native lung enabling true assessment of pulmonary function. [...]this study highlights PCRTO as a feasible, safe, and informative complement to conventional V-A ECMO weaning.

An implantable left ventricular assist device (LVAD) is indicated as a bridge to transplantation or recovery in the United Kingdom (UK). The mechanism of action of the LVAD results in a unique state of haemodynamic stability with diminished arterial pulsatility. The clinical assessment of an LVAD recipient can be challenging because non-invasive blood pressure, pulse and oxygen saturation measurements may be hard to obtain. As a result of this unusual situation and complex interplay between the device and the native circulation, resuscitation of LVAD recipients requires bespoke guidelines. Through collaboration with key UK stakeholders, we assessed the current evidence base and developed guidelines for the recognition of clinical deterioration, inadequate circulation and time-critical interventions. Such guidelines, intended for use in transplant centres, are designed to be deployed by those providing immediate care of LVAD patients under conditions of precipitous clinical deterioration. In summary, the Joint British Societies and Transplant Centres LVAD Working Group present the UK guideline on management of emergencies in implantable LVAD recipients for use in advanced heart failure centres. These recommendations have been made with a UK resuscitation focus but are widely applicable to professionals regularly managing patients with implantable LVADs.

Background Rejection is a major cause of mortality and morbidity in heart transplant (HTx) recipients. Current methods for diagnosing rejection have limitations. Imaging methods to map the entire left ventricle and reliably identify potential sites of rejection is lacking. Animal studies suggest FDG PET-CT (FDG PET) could have potential application in human HTx recipients. Methods Between December 2020 and February 2022, all HTx recipients at Harefield Hospital, London, with definite or suspected rejection underwent FDG PET in addition to routine work-up. Results Thirty HTx recipients (12 with definite and 18 with suspected rejection) underwent FDG PET scans. Overall, 12 of the 30 patients had FDG PET with increased myocardial avidity, of whom 2 died (17%). Eighteen patients of the 30 patients had FDG PET with no myocardial avidity and all are alive (100%, p  = 0.15). All patients with definite rejection, scanned within 2 weeks of starting anti-rejection treatment, showed increased myocardial avidity. In 5 cases, FDG PET showed myocardial avidity beyond 6 weeks despite pulsed steroid treatment, suggesting unresolved myocardial rejection. Conclusion Preliminary findings suggest FDG PET may have a role in diagnosing cardiac transplant rejection. Future blinded studies are needed to help further validate this.
