COVID-19 in a patient implanted with a total artificial heart: a case report

Background

The coronavirus disease 2019 (COVID-19) was first identified in December 2019 and is currently still a public health issue affecting millions of people worldwide. Heart failure patients are known to be at higher risk of morbidity and mortality in this case. Yet, few data exist concerning COVID-19 among patients with a left ventricular assistance device, and even less among those with a total artificial heart (TAH).

Case summary

A 27-year-old man with Marfan syndrome underwent prophylactic ascending aorta replacement. Shortly after surgery completion, he developed refractory cardiogenic shock with biventricular dysfunction leading to veno-arterial extracorporeal membrane oxygenation (VA-ECMO) implantation. In the context of no appropriate eligible donor during the following 10 days while waiting on the heart transplantation list, the patient was scheduled for a TAH as a bridge to transplantation. Meanwhile, he developed an acute respiratory distress syndrome secondary to SARS-CoV-2. The patient was successfully treated with corticosteroids, prone positioning and mechanical ventilation, and heart transplantation occurred 5 weeks after COVID-19 onset.

Discussion

Here, we report the first case of a patient presenting with COVID-19 infection following TAH implantation in a bridge to transplantation. We highlight that (i) cardiogenic shock patients simultaneously infected by COVID-19 should be treated instantly with all-time available technology to ensure best outcomes, including TAH and prone positioning, (ii) heart transplantation safety 5 weeks after COVID-19 onset.
