Aortic root reconstruction is a demanding surgical procedure still associated with a significant morbidity. Arguably, the most demanding aspect of the operation is reestablishing continuity between the prosthetic graft replacing the aortic root and the coronary arteries. With the objective of simplifying the possible challenges of coronary reimplantation, we designed a new model of aortic root graft with prefabricated coronary branches. We used this technique in 8 patients (6 males, 2 females; mean age, 54 years). There were 6 modified Bentall procedures and 2 valve-sparing root replacements with the “reimplantation” technique. There was no mortality or morbidity related to the use of this new prosthetic graft. Our purpose was to report in detail the technique of aortic root reconstruction using this new graft with prefabricated coronary branches. The use of this graft may simplify the procedure and offer a valuable tool for aortic root reconstruction in cases where the reimplantation of the coronary buttons may represent a technical challenge.

Background: Coronary button reimplantation can represent a technical challenge of aortic root reconstruction that can be associated with significant morbidity and mortality. With the goal of simplifying coronary reimplantation and reducing the incidence of related complications, we designed a new Dacron graft with prefabricated coronary branches to minimize coronary artery mobilization and prevent the potential mechanical complications of reattachment to the body of the graft. Methods: Between June 2010 and May 2012, we implanted the graft in eight patients (six males, two females) ranging in age from 42-68 years (mean, 54 years). Six procedures were modified Bentall reconstructions, and two procedures were valve-sparing root replacements using the reimplantation technique. Results: There were no complications and no morbidity or mortality related to coronary reattachment. All patients were alive and doing well at a mean follow-up of 26 months (range, 17-38 months). At an extended mean follow-up of 42 months (range, 25-56 months), one patient died of stroke-related complications. No radiologic or clinical evidence of impairment of coronary perfusion was identified in any patient. Conclusions: The use of this new graft model may simplify the technique of root reconstruction and potentially lower the incidence of mechanical complications related to coronary button reimplantation.

A bicuspid aortic valve sometimes coincides with a sinus of Valsalva aneurysm having a coronary artery anomaly. A meticulous aortic root replacement strategy is needed in these cases. In a 64-year-old man, the left coronary arteries (LCA) with an aberrant origin were excised together and reattached to the side hole of a valved conduit via a short Dacron graft. To prevent the formation of an aneurysm at the site, a strip of Dacron graft was sutured from outside between the LCA. The procedure for aortic root replacement with a coronary anomaly needs a case-by-case surgical strategy.
