Regional wall motion abnormalities in coronary artery disease
Posted by: Johnson Francis on: 27 Sep, 2009
Echocardiography is one of the simplest investigations to assess the myocardial regional wall motion abnormalities in coronary artery disease. Regional wall motion abnormalities can also be assessed by nuclear imaging and cine CT (computerised tomography) scan / MRI (magnetic resonance imaging). The wall motion is scored from 1 to 4 depending on whether it is [...]
Tags: a dyskinetic segment can become akinetic causing improvement in the wall motion score, akinesia means absence of contration and dyskinesia means bulging out in systole. In order to standardise the reporting of wall motion abnormalities, akinesia of apical septal segment, akinesia or dyskinesia. Hyokinesia means reduced contraction, American Society of Echocardiography has brought out a 17 segment model for left ventricular wall motion abnormalities. The segments are analysed from 6 views, apcial segment at the apex, Apex, apical 2C view shows seven segments, apical 4C view, apical anterior, apical anterior could be either by the RCA or LAD, apical anterior segments, apical four chamber, apical four chamber view, apical inferior segment, apical lateral, apical lateral and apical inferior, apical level, apical segment can be supplied either by the LAD or LCX, apical septal, Apical septal and mid septal segments are supplied by the LAD, apical septal segment appears thin, apical two chamber and parasternal short axis view at the levels of mitral valve, Apical two chamber view, basal anterior, basal anteroseptal, basal anteroseptal and mid anteroseptal on the septum, basal inferior, basal inferior. Mid inferior segment is supplied by the RCA, basal lateral, basal posterior, basal posterior and mid posterior in the posterior wall, basal septal, Basal septal segment belongs to the RCA territory, Both basal anteroseptal and mid anteroseptal territories are supplied by the left anterior descending coronary artery, cine CT, computerised tomographic scan, coronary artery disease, dyskinesia of apex and apical lateral segments, echo video at the end of the post, echocardiogram video, Echocardiogram video in multiple projections, Echocardiography is one of the simplest investigations to assess the myocardial regional wall motion abnormalities, four segments and two coronary territories, hypokinesia, hypokinesia of the mid anteroseptal region in the parasternal long axis view, information about 7 segments, LAD. Basal posterior and mid posterior segments can be supplied either by the right coronary artery, LCX, Left circumflex coronary artery, magnetic resonance imaging, mid anterior, mid anterior could be in the LAD or LCX territory, mid anteroseptal, mid inferior, mid inferior segments, mid lateral, mid lateral and basal lateral segments are in the LCX territory, Mid lateral segment is in the LCX territory, mid posterior and mid inferior, mid posterior segment could be either by the RCA or the LCX. Mid septal and mid anteroseptal segements are in the LAD territory, mid septal, mid septal and mid anteroseptal hypokinesia, mitral valve level, MRI, papillary muscle level, papillary muscles and apex, parasternal long axis, parasternal long axis view, parasternal short axis view, PSAX, PSAX view, PSAX view at the papillary muscle level, RCA, recovery can also occur after revascularisation of hibernating myocardium, Regional wall motion abnormalities, Regional wall motion abnormalities can be assessed by nuclear imaging, segments at the apical level are apical septal, segments at the mitral valve level, Segments in parasternal long axis view, segments in the LAD territory, sements at papillary muscle level are mid septal, sements belong to the LAD territory, supplied by the right coronary artery, three levels for assessing wall motion scores, wall motion abnormalities in LAD territory., wall motion is scored from 1 to 4 depending on whether it is normal wall motion, Wall motion score can improve when areas of stunned myocardium regain contractility, Wall motion scores assigned to all the segments are added to get the total wall motion score
