Objective: The Ozaki procedure for aortic valve reconstruction (AVr) has been approached by standard sternotomy with a very low mortality, highly reproducible rate and a good midterm result. We described a technique of AVr where the aortic valve is exposed through a hemi-sternotomy. Minimally invasive AVr can be safely performed via hemi-sternotomy with standard equipment. Less surgical trauma to the sternum has the potential benefit of less pain and shorter intensive care and hospital stay. We have successfully employed this procedure in two cases of Avr. Patient: From 01/02/2018 to 01/06/2018, 2 patients with severe aortic valve regurgitation underwent minimally invasive Ozaki procedure through via an upper hemi-sternotomy at the Cardiovascular Center, E - Hospital, Vietnam. The pericardium was harvested upper ministernotomy and the Ozaki procedure was accomplished similarly to the conventional technique. We demonstrate the harvesting of the pericardium and Ozaki aortic valve repair technique via an upper hemi-sternotomy. Good exposure is obtained for aortic valve surgery with standard aortic and the femoral vein cannulation to establish cardiopulmonary bypass (CPB). Results: The mean operation time was 120 minutes, and mean skin incision length was 65 mm. There were no intraoperative or postoperative complications. Intraoperative TEE showed all competent valves no stenosis was detected. The results was reconfirmed by transthoracic echocardiography before discharge Conclusion We successfully performed Minimally invasive Ozaki procedure for two patient Medium-term results for our original AVR were excellent. The lack of long-term data will be addressed and resolved in the future. Further assessment and bigger data are needed.
