Venting of the left ventricle helps in decompressing the heart and improves visibility during surgery. Venting may be performed by direct cannulation of the left ventricle or the pulmonary veins. It may also be performed indirectly from the aortic root or pulmonary artery. We describe a method of left ventricular venting, by gravity, using the venous return of the heart
