Handheld echocardiography in patients with cardiovascular disease: to use or not to use, that is the question.

The physical examination is one of the most important diagnostic tools for physicians. Traditionally, a physical examination consists of inspection (looking), palpation (feeling), percussion (reflection of sound) and auscultation (listening). Handheld echography devices could become the new fifth element of a physical examination. The use of handheld echocardiography has recently increased because the devices have become smaller, easier to handle and more affordable. Handheld echocardiography is used by many specialists involved in acute cardiovascular care. In this narrative review we give a summary of the diagnostic accuracy and limitations of cardiovascular physical examination combined with handheld echocardiography. In patients with cardiovascular disease, adding handheld echocardiography to physical examination increases the sensitivity for detecting valvular heart disease (71% vs 46%) and left ventricular dysfunction with an ejection fraction < 50% (84% vs 43%). Handheld echocardiography might be better for ruling out diseases with a low pre-test probability than in confirming diseases with a high pre-test probability.

Adapting the role of handheld echocardiography during the COVID-19 pandemic: A practical guide.

The COVID-19 pandemic has altered our approach to inpatient echocardiography delivery. There is now a greater focus to address key clinical questions likely to make an immediate impact in management, particularly during the period of widespread infection. Handheld echocardiography (HHE) can be used as a first-line assessment tool, limiting scanning time and exposure to high viral load. This article describes a potential role for HHE during a pandemic. We propose a protocol with a reporting template for a focused core dataset necessary in delivering an acute echocardiography service in the setting of a highly contagious disease, minimising risk to the operator. We cover the scenarios typically encountered in the acute cardiology setting and how an expert trained echocardiography team can identify such pathologies using a limited imaging format and include cardiac presentations encountered in those patients acutely unwell with COVID-19.

A tricky case of cardiogenic shock: Diagnostic challenges in the COVID-19 era.

Myocardial wall rupture should be considered in patients presenting with hypotension and STEMI especially of delayed onset. Diagnosing this entity in the COVID-19 era can be challenging-handheld echocardiography may aid toward this end.

Tablet-Based Limited Echocardiography to Reduce Sonographer Scan and Decontamination Time during the COVID-19 Pandemic.

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/m2). 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.
