Shunt in critically ill Covid-19 ARDS patients: Prevalence and impact on outcome (cross-sectional study)

PURPOSE: To examine critical Covid-19-acute respiratory distress syndrome (C-ARDS) patients requiring mechanical ventilation (MV), using transthoracic echocardiography (TTE) coupled with bubble test (BT), in order to search a right/left shunt. METHODS: A Cross-sectional and comparative study compari...

Sumario:PURPOSE: To examine critical Covid-19-acute respiratory distress syndrome (C-ARDS) patients requiring mechanical ventilation (MV), using transthoracic echocardiography (TTE) coupled with bubble test (BT), in order to search a right/left shunt. METHODS: A Cross-sectional and comparative study comparing several parameters according to the presence or not of shunt. RESULTS: 75 patients were included. Twenty-three shunts (31%) were detected: patent foramen oval (PFO) type [n=11 (15%)] and trans-pulmonary transit of bubbles (TPBT) [n = 12 (16%)]. The shunt did not affect P/F ratio (P/F=77 vs 81, p=0.97), nor mortality. CONCLUSION: A right/left shunt was detected in a third of studied patients similarly between PFO and TPBT without significant impact on P/F ratio or outcome.
