Wall motion analysis using SSFP sequences. Wall motion analysis using SSFP sequences involves division of the left ventricular myocardium into slices and segments (a). The latter extend clockwise from the junction between the interventricular septum and the right ventricular free wall (beginning of segment 1 and end of segment 6) (b). As shown in (c), the concordance of radial wall motion observed in healthy control subjects is highly disrupted in patients with heart failure and a left bundle branch block (LBBB).
