The document discusses the views and measurements obtained from a two-dimensional echocardiography exam. It describes the four main transducer windows used: parasternal, apical, subcostal, and suprasternal. From these windows, standard views are obtained including PLAX, RVIT, various short axis views of valves and structures. Measurements of chambers, walls, valves and other cardiac structures are made in these views. Assessment of systolic function includes linear and volumetric measurements to calculate ejection fraction and wall motion analysis.
42. This is done by tracing the epicardial to calculate
the total ventricular volume and the endocardial
border to calculate chamber volume.
LV mass = 1.05 (total volume – chamber volume)
Evaluation of LV Mass
43. Evaluation of LV Mass
Total volume= Total area x length
Chamber volume = Chamber area x Length
Myocardial volume = Total volume – Chamber volume
LV mass = Myocardial volume x density
LV mass = Myocardial volume x 1.05
50. For this method, endocardial borders are traced in apical four-chamber
and two-chamber views and are used to define a series of orthogonal
diameters (a and b) as follows:
V = (p ) S ai bi x (L)
4 20
Using 20 disk for i = 1 to i = 20
This calculation is done by computer software.
Simpson’s Rule
62. In the short axis view at the base
(MV), the LV is divided into:
1. Anterior wall
2. Lateral wall
3. Posterior wall
4. Inferior wall
5. Interior septal wall
6. Anterior septal wall
Wall Segments
63. In the short axis view at the mid-left
ventricle (the papillary muscle level),
the LV is divided into:
1. Anterior wall
2. Lateral wall
3. Posterior wall
4. Inferior wall
5. Interior septal wall
6. Anterior septal wall
Wall Segments
64. In the short axis view at the apex
the LV is divided into:
1. Anterior wall
2. Postero-lateral wall
3. Inferior wall
Wall Segments
