We present a case of left ventricular outflow tract (LVOT) obstruction after double valve re-replacement with bioprostheses. A 72-year-old man, who had undergone double valve replacement (DVR) with bioprosthetic valves 9 years previously, underwent re-replacement of valves because of structural valve deterioration. However, owing to LVOT obstruction related to the bioprosthesis in the mitral position, acute pulmonary edema occurred immediately after surgery. LVOT obstruction was diagnosed by emergent cardiac catheterization. So prompt re-replacement surgery using a mechanical prosthesis was performed.
