Abstract

Back ground Ascending aortic diseases are life-threatening conditions that have an increasing incidence. The modified Bentall procedure has become the technique of choice used to treat such diseases. Objectives This study evaluates early outcomes of patients who underwent modified Bentall procedure as a treatment of ascending aortic diseases. Patients and methods A total of 75 patients who underwent modified Bentall operation for ascending aortic diseases at the National Heart Institute during a 3-years period (July 2015 to August 2018) were studied prospectively. The included patients were divided according to the type of aortic disease into two groups: group A included 50 patients with aortic root aneurysm with no dissection, and group B included 25 patients with type A aortic dissection. Short-term outcomes of the two groups were collected and compared with each other. Results The mean age was 44.72±12.89 years in group A and 49.77±13.45 years in group B. Male sex represented 76% (38 patients) in group A and 68% (17 patients) in group B. BMI was similar between the two groups. Group A had a statistically significantly lower mean values of operative time (P<0.001), cardiopulmonary bypass time (P=0.024), and cross-clamp time (P=0.007). However, group B had a statistically significant higher mean values of circulatory arrest time (P<0.001). There was no statistically significant difference between the two groups regarding the early postoperative period. Early mortality was 5/50 (10%) patients in group A and 5/25 (20%) patients in group B, with no significant difference between the two groups. Conclusion Despite higher mortality rates being noticed in type A dissection group, our results are still comparable to the internationally published results. Modified Bentall operation is reliable and considered the standard practice for surgical treatment of ascending aortic diseases.
