The vessel takes more than 3 heartbeats to fill, but still fills completely. The vessel never fills beyond a trickle. The Ventriculogram Many coronary angiograms include a left ventriculogram, a dye injection into the left ventricle. The RAO ventriculogram is the view used to assess left ventricular ejection fraction. Both views can be used to see if some part of the wall of the left ventricle is infarcted - that area will not move normally.
Mitral regurgitation is assessed with the ventriculo- gram.
Dye regurgitating through the mitral valve during systole will look like a puff of smoke. The layout of the vessels of the heart is ord- erly and simple. These 2 grooves are perpendicular to each other. In a right dominant coronary circulation, the right coronary artery gives off the posterior descending coronary artery. In a left dominant coronary circulation, the left circumflex coronary artery gives off the posterior descend- ing coronary artery.
