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.
