Stroke volume
The stroke volume (SV) is referred to as the volume of blood ejected into the aorta or main pulmonary artery during each cardiac cycle. The stroke volume index (SVI) is the stroke volume corrected for the body surface area (BSA).
Usage
The stroke volume is another integral parameter used for t...

Retroaortic coronary course
A retroaortic course refers to a coronary artery taking its route posteriorly between the non-coronary sinus and the interatrial septum and is considered a ‘benign anomalous course’.
Epidemiology

Echocardiography
Echocardiography refers broadly to the use of diagnostic ultrasound as it pertains to the heart and cardiovascular system. The features of the imaging equipment used, as well as the principles underlying image generation, are analogous to other sonographic applications. It is primarily used to n...

Heart failure with reduced ejection fraction
Heart failure with reduced ejection fraction (HFrEF) is a type of heart failure due to left ventricular dysfunction (left heart failure) classified by a left ventricular ejection fraction of 40% or less. Heart failure with reduced ejection fraction occurs when the left ventricle is unable to con...

Retroaortic anomalous coronary sign (echocardiography)
The retroaortic anomalous coronary (RAC) sign describes the sonographic appearance of an anomalous left coronary artery traveling posteriorly to the aortic root. It is most commonly observed with anomalous origin of the left circumflex artery from the right sinus of Valsalva, but is also describ...

Myocardial performance index
Myocardial performance index, also known as Tei index was introduced in 1995 by Tei et al 1. It gives information about global ventricular function 2.
It is calculated by dividing sum of isovolumetric contraction time (IVCT) and isovolumetric relaxation time (IVRT) with ejection time (ET), i.e....
