- Abstract: Case 1: A 60-year-old female with subarachnoid hemorrhage was diagnosed with infectious endocarditis. The echocardiography showed severe aortic regurgitation due to quadricuspid valve and patent foramen ovale. We performed aortic valve reconstruction using autologous pericardium (Ozaki procedure) and patent foramen ovale direct closure. Case 2: A 54-year-old male was diagnosed with aortic regurgitation. The echocardiography showed severe aortic regurgitation due to quadricuspid valve. We performed the Ozaki procedure. The most common surgical technique for quadricuspid aortic valve is reported to be va1ve replacement. In the present study, we experienced two cases of successful aortic valve reconstruction using autologous pericardium. The Ozaki procedure is often indicated for congenital quadricuspid aortic value because of providing physiological hemodynamics without anticoagulation.
