Domain 1: Mitral valve and systolic anterior motion | |
---|---|
Score | Observation |
2 | Able to determine SAM – septal contact point with precision such that images could allow determination of the length of AMVL in contact with septum at maximum excursion (or if no contact – ability to measure with precision the distance from AMVL tip to septum (Analogous to parasternal long axis m-mode measurement of E-point septal separation [EPSS] distance)) |
1 | Able to localise approximate SAM – septal contact point (or, if there is no contact with the septum, able to localise approximate anterior leaflet tip position at point of maximum excursion) |
0 | Unable to determine tip position of the anterior leaflet in relation to the interventricular septum |
Domain 2: Target septum | |
Score | Observation |
2 | Able to define endocardial border of basal ventricular septum in both RV and LV with visualisation of central intra-septal ‘fusion line’ between RV and LV. On-axis images |
1 | Able to define endocardial border of proximal ventricular septum in both RV and LV but no visualisation of central intra-septal ‘fusion line’ between RV and LV |
0 | Unable to clearly define endocardial border of one or both sides of the ventricular septum. |
Domain 3: Adjacent structures;
Mid septum, Right ventricular cavity, anterior papillary muscle | |
Score | Observation |
2 | 3 key structures |
1 | 2 key structures |
0 | 0 or 1 key structure |
