An apico-aortic shunt enables a reduction in the aortic transvalvular pressure gradient. It is recommended for patients with symptomatic severe stenosis when anatomical constraints contra-indicate valvular replacement. The authors report the case of a patient who underwent this uncommon procedure, which was indicated due to previous coronary bypass surgery using both mammary arteries, plus massive calcification of the ascending aorta. Angio-haemodynamic investigation and MRI performed three years and five years respectively following the procedure confirmed its efficiency. An analysis of the few reported series confirms the value of this special procedure.
