During an ablation procedure an aortic dissection occurred.During the procedure, the sheath was advanced into the superior vena cava.At this moment the dilator fell anterior, the user rotated the sheath set to be posterior however the sheath set was in contact with the anterior septum during the rotation.Contrast was injected and the wall of the aorta was tinted indicating a dissection had occurred.Transesophageal echo, transthoracic echo, and computed tomography confirmed the dissection.Patient symptoms included an increase in aortic pressure and a small aortic hematoma.The procedure was ended and prothromplex was administered to stabilize the patient.There were no performance issues with any abbott device.
