a
High quality: Well defined endo‐ and epicardial borders at end‐systole. No ghosting due to patient breathing. No flow artifact.
b
Adequate quality: One or more of the following were present: Slight blurring of endo‐ and epicardial borders at end‐systole. Slight artifact due to flow within blood pool but not affecting myocardium. Slight ghosting due to patient breathing.
c
Nondiagnostic: One or more of the following are present: Loss of endo‐ and epicardial borders at end‐systole; ghosting due to respiration.
