Kurzfassung:
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.
