Event Description

It was reported that immediately following a cryo ablation procedure, the patient went into left atrial flutter and tachycardia.Mapping the flutter was attempted with the mapping catheter but the image was not clear.The balloon catheter and mapping catheter were then removed from the patient and another manufacturer's mapping catheter was inserted into the sheath which resolved the issue.The atrial flutter was ablated with another manufacturer's radiofrequency (rf) catheter and the right inferior pulmonary vein (ripv) ostium was touched-up.The rf catheter and sheath were removed from the left atrium and placed in the right atrium.Intracardiac echocardiography (ice) was placed back into the patient's heart to determine if there was any effusion following the ablation.The patient's blood pressure began to drop and an effusion was seen on ice.Effusion had not been seen at the beginning of the case and the patient had previously remained stable throughout the case.An anticoagulant antagonist medication was administered and a drain was p laced.Blood was drained and minimal blood pressure support was given.Once the effusion was drained, the patient's blood pressure normalized and the patient became hemodynamically stable.After ten minutes, more blood was drained and then no more effusion was seen on ice.The patient was admitted to the intensive care unit (icu) for two nights for observation.Additional, but minimal, drainage was performed again.The drain was removed and the patient was discharged.No further patient complications have been reported as a result of this event.
