Impaired relaxation on echocardiogram

• What should be included in an Echocardiographic study in patients with diastolic dysfunction?

  Thus, when perform- ing an echocardiographic study in patients with potential dia- stolic dysfunction, one should search for signs of impaired LV relaxation, reduced restoring forces and increased diastolic stiffness.

• What happens if myocardial relaxation is delayed?

  When myocardial relaxation is markedly delayed, there is a reduction in the E/A ratio (,1) and a prolongation of DT (.220 ms). In addition, in the presence of bradycardia, a characteristic low middiastolic (after early filling) mitral inflow velocity may be seen, due to a progressive fall in LV diastolic pressure related to slow LV relaxation.

• Can echocardiography predict LV stiffness and filling pressure?

  Myocardial relaxation, LV stiffness, and filling pressures can only be assessed indirectly in the echocardiography labora- tory, because the prediction of hemodynamic data with echocardiography often implies simplifying assumptions, which may be valid in a given patient population but are not necessarily applicable to all patients.

• Can stress echocardiography cause wall MO- TION abnormalities?

  With any form of stress echocardiography, wall mo- tion abnormalities are sometimes more apparent in immediate or early recovery. Therefore, it is recommended that all imaging views are repeated at that time. Table 1 Optimal machine settings and UEA administration techniques for LVO during stress echocardiography

  relaxation is nearly complete at minimal LV pressure. Con-traction and relaxation belong to the same molecular pro-cesses of transient activation of the myocyte and are closely intertwined.3 Relaxation is subjected to control by load, inactivation, and asynchrony.2 Increased afterload or late systolic load will delay myo-

  diastolic heart failure (i.e. impaired relaxation of the ventricle in diastole) and is becoming increasingly apparent as a common and significant predictor of adverse outcomes [12]. In one study, around 60% of surgical patients over the age of 65 had evidence of diastolic dysfunction on TTE despite a normal

  Abnormal LV relaxation is one of the first manifestation of diastolic dysfunction. Mitral annulus e’ velocity is a clinically reliable parameter for LV relaxation. Diastolic function and filling pressure can be assessed by simple Echo-Doppler parameters at rest and with exercise.

Thus, when perform-ing an echocardiographic study in patients with potential dia-stolic dysfunction, one should search for signs of impaired LV

This latter grade may be reversible with reduction of preload or irreversible with no benefit from
