Redo aortic root - complexity vs simplicity with choice of device selected

The field of cardiac surgery continues to evolve significantly and one such example of advancement is aortic root replacement. In the setting of prior cardiac surgery, operative complexity increases due to adhesions, surgically-altered anatomy, and previously implanted prosthetic graft material. Device choice plays a significant role in balancing operative complexity with achieving simplicity and optimal clinical outcomes.

This review explores the critical considerations necessary in performing redo aortic root surgery and the impact that device selection can have on the procedural complexity and clinical outcomes. This review was formulated by a systematic identification of published and unpublished laboratory and clinical studies evaluating these technologies.

Redo aortic root surgery represents one of the most challenging procedures in cardiac surgery, and the choice of both surgical technique and prosthetic device used are critical factors which influence the clinical success of the operation and the long-term outcomes for patients. By understanding the unique challenges of root replacement in a reoperative setting and the characteristics of different prosthetic devices, a tailored approach must be employed toward the best possible outcomes.
