BACKGROUND: Limited assessments with handheld ultrasound have found meaningful
clinical use in the care of acutely ill patients. However, there are limited data
on incorporating handheld-based limited echocardiography into the
echocardiography laboratory. The purpose of this study was to assess the efficacy
of limited handheld tablet echocardiography as an alternative to traditional
echocardiography during the coronavirus disease 2019 (COVID-19) pandemic as a
means to limit exposure while providing essential clinical information. METHODS:
Ninety consecutive inpatients with known or suspected COVID-19 were scanned
according to laboratory COVID-19 guidelines using a limited 11- to 20-clip
protocol on a tablet sonograph. The primary assessment was length of study time.
Comparison data were drawn from comprehensive echocardiographic examinations
ordered on intensive care patients not under COVID-19 precautions. RESULTS: Over
a 36-day time period, a total of 91 requests were deemed to be appropriate for
echocardiography on patients with suspected or confirmed COVID-19 (average age,
67 years; 64% men; mean body mass index, 32 kg/m(2)). Of these, 90 (99%)
examinations were performed using a handheld device, and all were deemed
diagnostic and provided sufficient information for the clinical care team.
Sonographer scan time decreased from an average of 24 ± 6.8 min on a traditional
platform to 5.4 ± 1.9 min on a tablet. CONCLUSIONS: Limited handheld
echocardiography can be successfully implemented in the echocardiography
laboratory for screening of COVID-19-related cardiac conditions. The protocol
performed with handheld tablet ultrasound provides adequate diagnostic
information of major cardiac complications of COVID-19 while decreasing
sonographer contact and simplifying decontamination.
