The technical failure of surgical aortic valve reconstruction using Ozaki’s procedure
We had 02 patients who required conversion to prosthetic valve replacement, and the reason was post-operative occlusion of left coronary arterial ostium caused by the cusps. Ozaki et al. conducted the study in 850 patients in which no case was converted to surgical valve replacement.11 On the other hand, Krane et al. operated on 103 patients with aortic valve reconstruction by Ozaki’s procedure showed that 01 patient suffered from left coronary arterial ostium occlusion caused by the left coronary cusp.17Coronary arterial ostium occlusion by cusps could occur as a consequence of the abnormally large cusps resulting in asymmetric condition; therefore, the precise measurement of the distance between 2 commissures plays a criterial role in achieving technical success of surgical reconstruction using the Ozaki procedure.
