Cardiac anatomy relevant to persufflation. Sketch illustrating the cardiac anatomy that has been historically relevant to the development of persufflation; Anterograde persufflation has been performed via the aorta or direct cannulation of coronary ostia, whereas retrograde persufflation has been performed by cannulation of coronary sinus with or without cannulation of the anterior cardiac veins.
