Question: What Is Sam In Echocardiography?

What is Sam in medical terms?

Systolic anterior motion (SAM) describes the dynamic movement of the mitral valve (MV) during systole anteriorly towards the left ventricular outflow tract (LVOT)..

What does Lvot mean?

What is Sam in heart disease?

Systolic anterior motion (SAM) is defined as displacement of the distal portion of the anterior leaflet of the mitral valve toward the left ventricular outflow tract obstruction.

What is chordal Sam?

Chordal SAM was defined as systolic anterior motion involving only the chordae tendineae (Fig. 2) [31]. The LVOT area was calculated from the length of the LOVT in the parasternal long- axis view at early systole.

What causes left ventricular outflow obstruction?

Left ventricular outflow tract obstruction Left ventricular outflow tract (LVOT) obstruction in HCM is caused by contact between the anterior leaflet of the mitral valve and the interventricular septum during systole.

What is SAM and MAM in nutrition?

Globally, approximately 33 million children under five years of age are affected by moderate acute malnutrition (MAM), defined as a weight-for-height z-score (WHZ) between -2 and -3, and at least 19 million children under five by severe acute malnutrition (SAM), defined as a WHZ of <-3.

What causes Sam?

Predisposing factors that cause SAM are (1) excessive anterior or posterior leaflet tissue; (2) any anatomical or surgical translocation of the mitral valve anteriorly; (3) aortomitral angle <120° (Figure 1; Supplementary Clip 1); (4) pathological or post-surgical correction elongation of the anterior leaflet; (5) ...
