Classification of left ventricular size: diameter or volume with contrast echocardiography?

Background Left ventricular (LV) size is an important clinical variable, commonly assessed at echocardiography by measurement of the internal diameter in diastole (IDD). However, this has recognised limitations and volumetric measurement from apical views is considered superior, particularly with the use of echocardiographic contrast. We sought to determine the agreement in classification of LV size by different measures in a large population of patients undergoing echocardiography. Methods and results Data were analysed retrospectively from consecutive patients (n=2008, 61% male, median 62 years) who received echocardiographic contrast for LV opacification over 3 years in a single institution. Repeat studies were not included. LVIDD was measured, and LV end-diastolic volume (LVEDV) calculated using Simpson's biplane method. Both measures were indexed (i) to body surface area and categorised according to the American Society of Echocardiography (ASE) guidelines as normal, mild, moderate or severely dilated. Of 320 patients with a severely dilated LVEDVi, only 95 (30%) were similarly classified by LVIDD, with 86 patients (27%) measuring in the normal range. LVIDDi agreement was poorer, with only 43 patients (13%) classified as being severely dilated, and 173 (54%) measuring in the normal range. Conclusions Currently recommended echocardiographic measures of LV size show limited agreement when classified according to currently recommended cut-offs. LV diameter should have a ...

How To Calculate Stroke Volume

This number sometimes varies since stroke volume factors include preload, afterload, contractility, and heart rate. Moreover, these factors can be affected by other diseases. For example, patients with hypertension will have increased afterload and patients with heart failure will have increased preload. Don’t be afraid of these terms; all of them will be simplified in this article. In this article, we will go through what is stroke volume, how to calculate stroke volume, and what are the different diseases and factors that affect stroke volume. And once you deeply understand it, you will love it! Stroke volume equation, Many formulas can be used to calculate the stroke volume. The most common stroke volume equation is: Stroke volume = end-diastolic volume – End-systolic volume. Where: Stroke volume = Volume ejected on one beat (mL) End-diastolic volume = volume in the ventricle before ejection (mL) End-systolic volume = volume in the ventricle after ejection (mL) Calculation Step by Step • Determine the end-diastolic volume by knowing how much blood is present in the ventricle before it contracts (can be done by another equation: Ejection fraction=SV/EDV) • Determine the end-systolic volume by knowing how much blood is present in the ventricle after it contracted. Here is how to calculate stroke volume. Example: An echocardiography of A 44-year-old woman shows that the amount of blood in her ventricles before it contracts is 140ml. The amount of blood in the ventricle aft...
