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 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.

Poor

LV gram quality is poor if it is difficult to analyze 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.

Fair

LV gram quality is fair if it is difficult to analyze 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.

Good

LV gram quality is good if it is easy to analyze 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.

Excellent

LV gram quality is excellent if it is very easy to analyze 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.
