Echo Registry 2024 EXAMINATION

mid systolic closure of the pulmonic valve seen on M-mode associated with PHTN - What is the flying W sign? Isovolumetric Contraction Time - What happens after the MV closes and before the Aortic Valve opens? MV opens - Which valve event ends isovolumetric relaxation? Early diastole (LV is not filled with blood) - When is LV pressure the lowest? MV closure - Which valve event starts isovolumetric contraction? Bradycardia - What increases the iso volumetric relaxation time? Chest X-rays. It is a still image - What study does not allow for the calculation of ejection fraction? Why? VTI = velocity time integral (how far blood travels in cm/s) CSA = cross sectional area - What is VTI and CSA? -patients with poor LVF -patients with moderate to severe AI - When does velocity time integral (VTI) work better?
