At the end of a ventricular tachycardia ablation, there was a pericardial effusion in the right ventricle.It is alleged that the cause of the perforation was the inquiry steerable diagnostic catheter.Transseptal puncture was performed and then mapping of the ventricular tachycardia was completed in the left ventricle.Once ablation was completed another ventricular tachycardia was then mapped.It was attempted to stimulate the right ventricle and push the inquiry steerable diagnostic catheter at the apex, but there was not a good localization.The inquiry steerable diagnostic catheter was repositioned and then it was noted on the screen of the x-ray that the inquiry steerable diagnostic catheter was out of the shadow of the heart.The patient was experiencing painful, tachycardia, and low blood pressure.The pericardial effusion was confirmed by an echocardiogram at the apex of the right ventricle.A pericardiocentesis was performed, 2 units of packed red blood cells, inotropes medications, and protamine was administered to stabilize the patient.There were no alleged performance issues with the inquiry steerable diagnostic catheter.
