- Aims Patients with advanced heart failure (AdHF) who are ineligible for heart transplantation (HTx) can become candidates for treatment with a left ventricular assist device (LVAD) in some countries, but not others. This reflects the lack of a systematic analysis of the usefulness of LVAD systems in this context, and of their benefits, limitations and cost-effectiveness. The SWEdish evaluation of left Ventricular Assist Device (SweVAD) study is a Phase IV, prospective, 1:1 randomized, non-blinded, multicentre trial that will examine the impact of assignment to mechanical circulatory support with guideline-directed LVAD destination therapy (GD-LVAD-DT) using the HeartMate 3 (HM3) continuous flow pump vs. guideline-directed medical therapy (GDMT) on survival in a population of AdHF patients ineligible for HTx. Methods A total of 80 patients will be recruited to SweVAD at the seven university hospitals in Sweden. The study population will comprise patients with AdHF (New York Heart Association class IIIB-IV, INTERMACS profile 2-6) who display signs of poor prognosis despite GDMT and who are not considered eligible for HTx. Participants will be followed for 2 years or until death occurs. Other endpoints will be determined by blinded adjudication. Patients who remain on study-assigned interventions beyond 2 years will be asked to continue follow-up for outcomes and adverse events for up to 5 years. Conclusion The SweVAD study will compare survival, medium-term benefits, costs and potential hazards between GD-LVAD-DT and GDMT and will provide a valuable reference point to guide destination therapy strategies for patients with AdHF ineligible for HTx.

- Background Coronavirus disease 2019 (COVID-19) spreading from Wuhan, Hubei province in China, is an expanding global pandemic with significant morbidity and mortality. Even though respiratory failure is the cardinal form of severe COVID-19, concomitant cardiac involvement is common. Myocarditis is a challenging diagnosis due to heterogeneity of clinical presentation, ranging from mild symptoms to fatal arrhythmia and cardiogenic shock (CS). The aetiology is often viral and endomyocardial biopsy (EMB) is the gold standard for definite myocarditis. However, the diagnosis is often made on medical history, clinical presentation, magnetic resonance imaging, and blood tests. Case summary We present a 43-year-old man with mixed connective tissue disease treated with hydroxychloroquine who rapidly developed CS 4 days from symptom onset with fever and cough, showing positive polymerase chain reaction nasopharyngeal swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA. While computed tomography of the thorax was normal, high-sensitivity troponin T was elevated and electrocardiogram showed diffuse ST elevation and low voltage as signs of myocardial oedema. Echocardiography showed severe depression of left ventricular function. The myocardium recovered completely after a week with mechanical circulatory support (MCS). EMB was performed but could neither identify the virus in the cardiomyocytes, nor signs of inflammation. Still the most probable aetiology of CS in this case is myocarditis as a sole symptom of COVID-19. Discussion COVID-19 patients in need of hospitalization present commonly with respiratory manifestations. We present the first case of fulminant myocarditis rapidly progressing to CS in a COVID-19 patient without respiratory failure, successfully treated with inotropes and MCS.
