In the COVID-19 pandemic, we performed a series of echocardiograms using
subcostal views. After placing a patient in prone position during
invasive mechanical ventilation, the echocardiogram transducer was
placed under the patient in the left subcostal position. This
performance allowed us to evaluate the function of the pulmonary valve
and estimate pulmonary pressure. This is a complement to the monitoring
with transthoracic echocardiogram in prone position.
