CRT-708 Development and Evaluation of a Smartphone Application for the Perioperative Care of Patients Undergoing Routine Cardiology Procedures.

Abstract

when enhanced motion occurred in mid or apical segments than when they did not (p¼0.01, 0.005, respectively). d-IVV correlated with d-WMSI of the mid and apical levels (r¼0.48, 0.42, p¼0.01, 0.03), while it did not for the basal level (r¼0.21, p¼0.3). ROC-curve showed that d-IVV detects global viability effectively (AUC¼0.761), however, sensitivity and specificity increased for mid and apical levels (AUC¼0.790, 0.868).CONCLUSION Mitral annular longitudinal motion during isovolumic contraction, represented by IVV and d-IVV, increase after LDDE in the presence of viable myocardium. Changes that occur in the mid and apical segments of the LV seem to contribute more to this effect than the basal segments.
