ABSTRACT
Aortic valve-sparing surgery is a delicate procedure that requires specialized skills to control aortic valve regurgitation. Therefore, simulating the surgery before performing it on a patient is good practice for inexperienced surgeons. Herein, we present our experience of a simulation surgery using a three-dimensionally printed aortic root model of a 60-year-old man with severe aortic regurgitation and aortic root enlargement. We fabricated the model using multi-slice computed tomography data. The model revealed the two pitfallsunbalanced commissure position and lower coaptation height of the right coronary cusp. We completed the simulation surgery from the proximal suture and valve reimplantation to coronary ostial reconstructions during approximately three hours with medical staffs. In the actual operation, the aortic valve regurgitation completely disappeared by accurately reconstructing the commissure in the Valsalva graft and adjusting the height of the right coronary cusp using central plication procedure. We believe that carrying out simulations before the actual surgery improves the surgeon's confidence and the patient's outcomes.
