Speckle myocardial imaging modalities for early detection of myocardial impairment in isolated left ventricular non-compaction

Abstract

LV SMI values are reduced in patients with iLVNC, even those with normal EF and PWTDI. The most accurate SMI modalities to discriminate between patients and controls are longitudinal sS mean of the six apical segments, LV apical rotation or LV torsion rate.
