Abstract
The aortic root replacement offers acceptable early and short-term outcome. The predictors for poor overall survival in patients undergoing ARR seems to be preoperative aortic dissection extending into the aortic arch, older age, depressed left ventricular function, associated coronary artery disease and prolonged cardiopulmonary bypass time require prolonged monitoring in the intensive care unit.
Repair of the ascending aorta can be performed with acceptable morbidity and mortality, however, emergency operations are associated with high morbidity and mortality.
We have divided our patients into 2 groups ,group A for aortic valve replacement and supra coronary conduit ,group B for Bentall’s procedure. we have detailed preoperative characteristics of patients which might affect surgical outcome.
Also we observed intraoperative surgical technique which might affect the outcome .We have analysed the postoperative outcome for all data collected within 6 months and 1 year.
We have compared operative CBP time ,cross clamp time, postoperative ICU stay, bleeding rate and aortic root diameter
we recommend doing Bentall’s procedures whenever technique mastering and availability of equipment is possible as there is a better short term outcome over AVR+supra coronary conduit.
As regard periprosthetic haematoma presented in 14 patients and need for reoperation (done in 2 patients 4%) due to dilatation of the remaining portion of the aortic root between the graft and the aortic valve (sinuses of valsalva).We recommend follow up MRI or CT scan within 6 months to 1 year as there is a high incidence of periprosthetic haematoma especially if AVR+supra coronary conduit procedure was done.
