Abstract

The modified Bentall procedure remains a gold standard of aortic root surgery. [1]. In 1968, Bentall and De Bono were the first to describe the surgical procedure for the reconstruction of the aortic root with a valved composite graft [2]. For years, this technique became the practice standard for surgical treatment of dysfunctions of the aortic valve, root, and ascending aorta [3– 5]. In the original method, late intra-operative bleeding was controlled using circumferential suture lines on the coronary peri-ostium areas and an overall aortic wraparound [2]. In the initial series, the postoperative complications like coronary detachment, formation of a false aneurysm, and need for reoperation in the Bentall operation were very high [2]. Since then, with increased experience of the surgeon and technical improvements such as pre-clotting of grafts with albumin, enhancements in pump oxygenator systems, and accurate heparin adjustments the rate of complications has significantly dropped [6]. Several modified techniques have also been developed to further reduce the rate of complications and improve patient outcomes [4, 7,8,9]. Currently, the modified Bentall techniques that incorporate coronary button mobilization have become the procedure of choice in many centers around the world [10,11,12]. Despite significant improvements with modified techniques, intraoperative blood loss and postoperative complications remain a major cause of morbidity and mortality. Therefore, the present study aims to evaluate this technique of modified Bentall's procedure for various conditions of ascending Aorta and evaluate the outcomes in southern Indian population.
