  • _____ ______ ______ is a 2D-based strain imaging modality used to calculate strain rate. .
    Speckle Tracking Echocardiography (STE)
  • Regional dilation in area of the scar can result in _________ _________.
    ventricular aneurysm. ( is defined as regional area of akinesis or dyskinesis and scar that has abnormal geometry in both diastole and systole)
  • Most commonly used assessment of LV systolic function is ______. Most commonly used method for quantitation of LV volume is ______.
    *EF *Simpson rule
  • Before acute reperfusion strategies for MI, ventricular thrombus was reported in 25-40% of patients with ________ MI.
    Anterior
  • what is shown in the image
    LV Pseudoaneursym
  • Typically with brief occlusion of 5 minutes- restores _______ seconds Occlusion of 30-60 minutes- restoring function may take ______ hours
    *6-120s *24-72hrs
  • What is shown in the image
    papillary muscle rupture
  • What is Chronic thrombus formation is most common after large anterior myocardial infarction, especially with involvement of the apex.
    Mural Thrombus
  • What is Kawasaki Disease.
    Is an infectious/inflammatory disease found in childhood. Major manifestation are rash and fever and associated with aneurysms of coronary arteries.
  • Clinical presentation of CAD includes:
    Stable angina, Unstable angina, MI, Ischemic cardiomyopathy, CHF, SCD
  • what are the Global parameters of LV function>
    Ventricular geometry Ejection fraction LV Volumes Diastole and systole
  • _________ is defined as a distinct break in the geometry of the left ventricular contour that is present in both diastole and systole with replacement of myocardium by fibrous scar tissue.
    Aneurysm
  • Delayed pericarditis aka ______________ can also occur after MI, Less prevalent, Consists of recurrent pain with pericardial fluid, Typically occurs around 6 weeks to 3 months post MI.
    Dressler syndrome
  • Post-infarction ______ ______ is reported in 30–40% in patients with STEMI.
    pericardial effusion
  • Write down from normal to aneurysmal wall motion.
    1 for normal contraction or hyperkinesia, *2 for hypokinesis 3 for akinesia, *4 for dyskinesia. *5 for aneurysmal segments
  • Surgical approaches to control heart failure in patients with ventricular aneurysm have included reduction ______ and ___ ______.
    myoplasty and Dor myoplasty.
  • Although the location of the WMA is an accurate marker for the site of ischemia or infarctions, the size of the WMA may be over or underestimated due to __________.
    tethering (Tethering refers to the impact that an abnormal segment has on normal adjacent segments, a WMA will be overestimated by ~ 15% due to this)
  • what is shown in the image
    myocardial diverticulum.
  • If coronary obstruction persists for a threshold period of time _______myocardial necrosis and persistent wall motion abnormalities develop. (irreversible myocardial necrosis).
    (>4 hours)
  • true/ false: aneurysm does not occur after non-transmural infarction
    True. (its a a dead space reservoir with no ability to eject blood from its diastolic volume and thus compromises stroke volume.)
  • _______ Myocardium occurs with transient occlusion of ____-____ minutes
    Stunned myocardium, 20-60 mins
  • Severity of WMA depends on if _____ vs _______ infarction
    transmural vs non-transmural infarction
  • True/ False: A free wall rupture is the most catastrophic complication of STEMI
    True. Involves the tearing or rupture of the acutely infarcted tissue
  • Most commonly identified CAD abnormality identified is
    Abnormal MV inflow
  • Larger effusion one should always considered a _____ _____.
    myocardial rupture
  • Right Ventricular Infarction Occurs in conjunction with________ MI (>90%)
    Inferior. (occluded RCA)
  • An infrequently encountered abnormality which may be confused for an infarct-related aneurysm is a ______ _________.
    myocardial diverticulum.
  • What are the Some major complications of Acute MI.
    ventricular free wall rupture ventricular septal rupture papillary muscle rupture (severe acute mitral regurgitation)
  • What is the normal strain rate?
    -20%
  • _______ is gold standard to assess origin and course of coronary arteries
    CTA
  • Whats shown in the image
    LV Aneurysm
  • What MI is shown in this image?
