Retrograde balloon dilatation of the aortic bileaflet ATSAP360mechanical valve with cerebral embolic protection. (A1) Incomplete closure of the anterior leaflet (38°) and normal closure of the posterior leaflet (25°) in diastole. (A2) Incomplete opening of both anterior (45°) and posterior (55°) leaflets in systole. (B) Manufacturer-provided range of movements for the ATS AP360 valve. (C) Quantitative analysis of the central and lateral orifices; insert, in vitro image of the ATS AP360 valve in the open position. (D) Carotid filters in both internal carotid arteries are shown with blue arrows. (E) Balloon dilatation through the central orifice opened the leaflets up to 85°. (F) Balloon dilatation through the lateral orifice opened the leaflets up to 85°. (G) Histopathology revealed scattered lymphocytes in fibrinous proteinaceous material; insert, debris found in the right-sided filter. (H1) Normalization of the closing angle after the procedure. (H2) Improvements in the opening angles after the procedure. (I) Preprocedural continuous wave Doppler ultrasound revealed a mean gradient of 91 mm Hg with a grade 2 valvular leak, whereas postprocedural continuous wave Doppler ultrasound showed a mean gradient of 36 mm Hg and no valvular leak.
