Bentall procedure is a cardiac surgery operation involving composite graft replacement of the aortic valve, aortic root and ascending aorta, with re-implantation of the coronary arteries into the graft. This operation is used to treat combined aortic valve and ascending aorta disease, including lesions associated with genetic disorder of connective tissue.
The aorta is the largest artery that stems from the heart and branches into smaller arteries to distribute oxygenated blood to all parts of the body. It can be divided into ascending aorta, aortic arch, descending throacic aorta and abdominal aorta. It is perform to correct defects of the aorta.
This surgery is performed under general anaesthesia. During the surgery, an incision is made along the middle of the chest to expose the heart. The heart’s activity is temporarily stopped so your surgeon can perform the operation, and blood flow is redirected to a bypass machine.
The diseased part of your aorta is excised and the valve is inspected. The diseased aortic valves are removed. The coronary arteries, along with a large button of the surrounding wall of the aorta are dissected. An artificial graft that has a mechanical or bioprosthetic valve is sutured to the ends of the aorta. Two holes are created in the graft, into which the coronary artery buttons are sewn. The valve replacement may be tested by your surgeon by streaming some blood into the area and checking for any kind of leakage. Once the repair is complete, the incision is sutured and bandaged. The entire procedure is normally completed in less than 5 hours.
After the surgery, you will be taken to the post anaesthesia care unit and connected to a ventilator where your vitals will be monitored. Before discharge, your doctor will give you a set of instructions to be followed such as:
