WebAn 8.5-F sheath was advanced into the coronary sinus under fluoro- scopic guidance, and a coronary sinus contrast venogram was obtained by occluding its ostium with a balloon catheter. Initial studies were used to develop a reliable technique of VOM cannulation. WebA sample venogram from an isolated heart preparation can be seen to the right. The green sheath contains a venogram balloon catheter. The balloon is inflated to block off antegrade flow and then contrast is injected retrograde, such that the coronary venous system (branching) is visible.
