This video demonstrates a redo operation in a patient in their 60s who had a previous biological aortic valve replacement and required an aortic root replacement with the Konect valved conduit. The patient had undergone a biological aortic valve replacement 10 years prior, which now exhibited a severely stenotic gradient across it. Additionally, the aortic root had become enlarged.
Femoral venous cannulation was first performed, followed by a redo sternotomy. The aortic cannula was placed high up in the ascending aorta. The surgeon then cross-clamped the aorta and retrograde cardioplegia was given. The aorta was excised, with particular attention paid to safely separating the right atrium from the previous aortic suture line.
Left and right coronary buttons were formed, and a 4.0 Prolene suture was used to mark the top of each button to prevent rotation. The previous aortic valve was removed, and pannus was seen under the valve, which was the reason for the stenosis. A Konect Resilia aortic valved conduit was used and was sutured to the annulus with horizontal mattress sutures without pledgets. The coronary buttons were then sutured to the conduit using continuous 5.0 Prolene, again without any pledgets.
Finally, the conduit was sutured to the distal ascending aorta, and the operation was concluded.
