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.

Objective Aortic valve replacement in minimally invasive approach has shown to improve clinical outcomes even with a prolonged cardiopulmonary bypass and aortic cross-clamp (ACC) time. Sutureless aortic valve implantation may ideally shorten operative time. We describe our initial experience with the sutureless 3f Enable (Medtronic, Inc, ATS Medical, Minneapolis, MN USA) aortic bioprosthesis implanted in minimally invasive approach in high-risk patients. Methods Between May 2010 and May 2011, thirteen patients with severe aortic stenosis underwent aortic valve replacement with the 3f Enable bioprosthesis through an upper V-type ministernotomy interrupted at the second intercostal space. The mean ± SD age was 77 ± 3.9 years (range, 72–83 years), 10 patients were women, and the mean ± SD logistic EuroSCORE was 15% ± 13.5%. Echocardiography was performed preoperatively, at postoperative day 1, at discharge, and at follow-up. Clinical data, adverse events, and patient outcomes were recorded retrospectively. The median follow-up time was 4 months (interquartile range, 2–10 months). Results Most of the implanted valves were 21 mm in diameter (19–25 mm). The CPB and ACC times were 100.2 ± 25.3 and 66.4 ± 18.6 minutes. At short-term follow-up, the mean ± SD pressure gradient was 14 ± 4.9 mm Hg; one patient showed trivial paravalvular leakage. No patients died during hospital stay or at follow-up. Conclusions The 3f Enable sutureless bioprosthesis implanted in minimally invasive approach through an upper V-type ministernotomy is a feasible, safe, and reproducible procedure. Hemodynamic and clinical data are promising. This innovative approach might be considered as an alternative in high-risk patients. Reduction of CPB and ACC time is possible with increasing of experience and sutureless evolution of actual technology.

Objective The Ozaki procedure for aortic valve reconstruction was reported in 2014 with low mortality, a highly reproducible rate and a good midterm result. However, the procedure still requires conventional sternotomy to be accomplished. The aim of the study was to start an initial evaluation for the feasibility of the minimally invasive approach in combination with the Ozaki technique. Methods From January 06, 2017, to January 12, 2017, nine patients with severe aortic valve diseases underwent minimally invasive Ozaki procedure through an upper ministernotomy. The pericardium was harvested endoscopically using three trocars in different intercostal spaces. Then, a ministernotomy was performed and the Ozaki procedure was accomplished in a similar manner to the conventional technique. We analyzed the in-hospital mortality and complications of this group. Results The mean age was 47.4 years and 55.6% patients were female. The predominant pathology was chronic rheumatic valve disease (66.7%) and other patients were diagnosed with a bicuspid aortic valve. The mean aortic cross-clamp time was 106.8 minutes, the mean cardiopulmonary bypass time was 153.6 minutes, the mean ventilation time was 8.4 hours, and the mean intensive care unit time was 1.6 days. No mortality was recorded in our series, no conversion to full sternotomy was required, one patient experienced right hemothorax requiring drainage, and one patient required valve replacement. Intraoperative transesophageal echocardiography and predischarge transthoracic echocardiography showed five competent valves and three valves with trivial regurgitation, and no stenosis was detected. Conclusions Ministernotomy combined with Ozaki procedure might be feasible, as well as an alternative to conventional sternotomy. This approach is associated with low mortality and morbidity and may be beneficial in younger populations.
