Left Ventriculogram Quality Grades

Following are the explanations for the different grades of LV gram quality:

Uninterpretable

LV gram quality is uninterpretable, if it is impossible to analyze heart-beat type, ventricular wall motion, mitral valve regurgitation, and left ventricular ejection fraction because of insufficient filling of the LV cavity, poor panning, and short film duration. So all the fields for analysis are marked as CNA (can not assess).

Poor

LV gram quality is poor, if it is difficult to analyze heart-beat type, ventricular wall motion, and mitral valve regurgitation and impossible to analyze left ventricular ejection fraction because of poor panning and short film duration. So only ejection fraction is marked as CNA (can not assess).

Fair

LV gram quality is fair, if it is difficult to analyze heart-beat type, ventricular wall motion, mitral valve regurgitation, and left ventricular ejection fraction with proper panning and enough film duration which covers at least three heart-beats. So nothing is marked as CNA (can not assess).

Good

LV gram quality is good, if it is easy to analyze heart-beat type, ventricular wall motion, mitral valve regurgitation, and left ventricular ejection fraction with good filling of the LV cavity, proper panning, and enough film duration which covers at least three heart-beats. So nothing is marked as CNA (can not assess).

Excellent

LV gram quality is excellent, if it is very easy to analyze heart-beat type, ventricular wall motion, mitral valve regurgitation, and left ventricular ejection fraction with perfect filling of the LV cavity, proper panning, and enough film duration which covers at least three heart-beats. So nothing is marked as CNA (can not assess).
