Intracardiac and vascular cannulae utilized during cardiopulmonary bypass

* Left ventricular vent enters right upper pulmonary vein then passes into left ventricle through mitral valve.
• Retrograde cardioplegia cannula enters right atrium and passes into coronary sinus.
Δ Aortic root vent allows suction to be applied to the aortic root, thereby indirectly emptying the left ventricle.
