![]() Left atrium can be assessed by linear measurement, area measurement and volume measurement. There are indirect signs of pulmonary hypertension, which are sometimes referred to in the report. RV free wall strain - uses strain analysis to look at right ventricular free wall contractility directlyĪssessing pulmonary pressures mainly relies on the presence of the tricuspid regurgitation jet, allowing us to calculate the pressure difference between the right ventricle (hence pulmonary artery) and the right atrium (which we estimates clinically via the jugular venous pressure, or with echocardiographic clues). S’ - describes velocity of tricuspid annulus movement towards the ultrasound probe TAPSE (Tricuspid annular plane systolic exclusion) - describe the extent of movement of the tricuspid annulus towards the ultrasound probe Normal ranges for parameters are therefore not important for this discussion. Right ventricular systolic function assessment is also subjective. Right ventricular end diastolic diameter (RVEDD) is sometimes quoted. Right ventricular size assessment is difficult and therefore largely subjective. “Elevated filling pressures” may call for escalating diuresis, but one needs to be cautious about potential inadequacy of the parameters and therefore one should not rely on this alone to make clinical decisions. “Restrictive diastolic filling” or “severe diastolic dysfunction” in the context of both ischaemic heart disease and congestive heart failure is very poor prognostic sign. Details of the parameters are therefore not important in this.Ĭlinically, the presence of significant diastolic dysfunction may tell us the possibility of diastolic heart failure as the cause of the patient’s shortness of breath, although the diagnosis remains one of exclusion and therefore relies on careful clinical assessment. Left ventricular diastolic function assessment is incredibly complex. However, in general, volume measurements are more accurate, reliable and reproducible than linear measurements.Ĭlinically, the use of linear measurements remains important for valvular heart disease follow-up, as surgical thresholds remain firmly defined by linear measurements, namely end diastolic diameter (LVEDD) and end systolic diameter (LVESD). In some ways, understanding the exact methods for deriving these measurements may not be as important. Left ventricular size could be assessed by linear measurements (LVEDD/LVESD), volume measurements (LVEDV, LVESV) using 2D images, or 3D volume measurements. Practically, assessment of function is limited to the ventricles. Cardiac chambersĪssessment of cardiac chambers basically entails their size and function. However, if we concentrate on the main themes, we can definitely decipher the main messages. Complexity of the echocardiogram report lies in the inclusion of clinically useful parameters that justify the conclusion about the various structures. Almost all abnormalities are graded mild, moderate, or severe.
