Introduction: The most frequent surgical procedure of severe left ventricular outflow tract obstruction due to severe aortic stenosis is aortic valve replacement, but there is an alternative and less conventional method described by Cooley used in patients with previous aortic valve replacement and severe aortic wall calcification that bypasses the left ventricular outflow tract through the implant of an apicoaortic valved conduit. Clinical case: We describe the case of 42 years old patient with severe aortic stenosis due to mismatched valve prosthesis previously installed treated by of apicoaortic conduit implanted through left posterolateral thoracotomy.
