When applying the stopcock/luer lock of the inlet line of the right ventricular assist device (rvad) to inflow cannula, there was an audible cracking sound and air was being entrained creating and airlock which stopped the rvad from circulating.The patient quickly became bradycardic and hypotensive.We were unsuccessful in removing the air from the circuit, requiring a new rvad circuit with oxygenator.Despite now being able to flow nearly 3l/min, patient's pulmonary artery (pa) pressures equaled systemic.On transesophageal echocardiogram (tee), her right ventricle (rv) was severely dilated and she was converted to venous arterial extracorporeal membrane oxygenation (va ecmo) and right femoral artery was accessed using a 17fr cannula over the wire.The pulmonary artery (pa) and right atrium (ra) cannula were y-d together as the outflow cannula.Next, the right superficial femoral artery (sfa) was accessed with a micropuncture kit using ultrasound guidance, and a 7fr cannula was inserted over the wire and connected to the inflow cannula for distal perfusion.The doctor removed the device.
