Description of Event or Problem

PATIENT WAS TAKEN TO THE OPERATING ROOM AND PLACED ON THE TABLE IN THE SUPINE POSITION. GENERAL ANESTHESIA WAS INDUCED; LINES AND MONITORING DEVICES WERE PLACED. PATIENT'S CHEST WAS PREPPED AND DRAPED IN THE USUAL STERILE FASHION. WHEN IT WAS TIME TO DO THE AVR [AORTIC VALVE REPLACEMENT], THE AORTIC VALVE WAS INSPECTED AND THERE APPEARED TO BE A CALCIFIED LESION DISTORTING THE RIGHT CORONARY LEAFLET. NEAR THE END OF THE AVR, SUTURES WERE PLACED THROUGH THE SEWING CUFF OF THE VALVE AND FASTENED IN PLACE USING COR-KNOTS. HOWEVER, THE FIRING MECHANISM STOPPED AT 8 AND IT STOPPED CUTTING WIRE. THE DEVICE WAS EXCHANGED FOR ANOTHER ONE AND THE PROCEDURE WAS COMPLETED WITHOUT ANY FURTHER INCIDENT. NO PATIENT HARM.
