Pump Controlled Retrograde Trial Off (PCRTO) For Weaning From VA-ECMO

Pump controlled retrograde trial off (PCRTO) is a weaning technique for venoarterial ECMO (VA-ECMO) in which pump speed is gradually decreased until net retrograde flow develops from the arterial to the venous limb of the circuit. This maneuver suspends mechanical circulatory support without decannulation, offering a real-time, physiologic test of native cardiac function while preserving circuit…
