Abstract

Minimally invasive aortic valve replacement through a right thoracotomy is frequently performed in patients with aortic valve disease. The Cor-Knot Device (LSI Solutions) is an automated fastener that secures valve sutures. This case report is for a patient who developed postcardiotomy shock during a minimally invasive aortic valve surgery. The patient was found to have an aortic root dissection involving 90% of the aortic root circumference, including bilateral coronary ostia. The autopsy revealed that the aortic damage could be explained by a direct aortic intimal tear from the distal tip of the device shaft. The device was most likely not in perfect apposition to the sewing ring because of the restricted angle and space between the ribs.
