Event Description

It was reported that a patient underwent an atrial fibrillation (afib) ablation procedure with a lassostar nav circular mapping catheter and the lasso was caught and could not be released from the valve with several maneuver attempts.During an afib procedure, after inserting the lasso, they began mapping the veins.After which the lasso approached to the mitral valve.The medical professional wanted to return the lasso back into the helios balloon and felt that the lasso was caught and could not be released from the valve.Several maneuver attempts were made to release but without success.It was decided to insert a transesophageal echocardiography (tee) in order to see what is happening inside the left atrium and with the help of the tee and another maneuver with the helios balloon and the sheath, the lasso catheter was released from the leaflet of the mitral valve and the operation ended successfully.There was no patient consequence and no damage to the catheter.The catheter did not go into the ventricles.
