Minimally invasive Ozaki procedure for aortic valve disease, preliminary results

Abstract

Objective. To assess the efficiency and realizability of the surgical technique of aortic valve reconstruction using autologous pericardium treated by glutaraldehyde in different aortic valve diseases such as aortic stenosis, aortic regurgitation, rheumatic and degenerative diseases of aortic valve. In 2014, Ozaki presented the technique described.

Materials and methods. In this work we analysed 10 cases of ministernomy combined with Ozaki procedure in patients operated at “Sukhanov Federal Center for Cardiovascular Surgery”.

Results. No hospital mortality was registered in our study. Intraoperatively, transition to a full sternotomy was not required. A mean time of aortic cross-clamping was 84.6 (± 14.4) minutes, a mean value of artificial circulation was 103.1 (± 17.7) minutes, a mean time of ventilation was 8.4 hours, and a mean time of staying in intensive care unit room was 1.6 days.

Conclusions. Minimally invasive approach combined with Ozaki procedure is realizable; it is an alternative to conventional sternotomy and should be used for patients in grave condition having concomitant diseases.
