Impact of Ozaki procedure in a patient with severe aortic stenosis and critically low left ventricular ejection fraction

A clinical case of successful surgical treatment in a patient with severe New York Heart Association (NYHA) functional class IIIIV heart failure, critical aortic stenosis, and extremely low left ventricular (LV) ejection fraction (EF) (16%) is presented. Aortic valve leaflet replacement was performed according to the Ozaki technique. The postoperative course was uneventful and the patient was discharged from hospital on day 11 after the operation. Clinical status and echocardiographic data were assessed at six months and one year after surgery. The results of follow-up showed clinical improvement, a decrease in the functional class of heart failure to NYHA I, restoration of global contractility of the right and left ventricles, a decrease in the severity of myocardial hypertrophy, and normal functioning of the autopericardial valve.
