Abstract: An apparatus for performing myocardial revascularization in a beating heart and left ventricular assistance condition comprises an arterial cannula, of a per se known type, arranged in the descending aorta, a novel arterial draining cannula, of a two cannula stage type, so arranged that the draining occurs from the left auricle and left ventricle, and a centrifugal pump allowing blood flow from the left ventricle to the aorta. The apparatus allow the patients to be operated on with the safety of a conventional extra-corporeal circulation and with a risk and cost reduction due to the off-pump technique.

Abstract: An apparatus for performing an aortal valvular surgery intervention on a beating heart comprises an outer mechanical circuit including a biopump and an infusion aortal cannula and being characterized in that it further comprises a left atrial cannula adapted to occlude the mitral valve so as to directly convey oxygened blood through a raising aorta by the outer mechanical circuit, thereby allowing to perform a cross aortotomy for exposing the aortic valve to operate thereon in an “open sky” manner.
