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) ....

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).

left ventricular outflow tractMorgan ◉ et al. The left ventricular outflow tract (LVOT) view (or five chamber view) is one of the standard views in a fetal echocardiogram. It is a long axis view of the heart, highlighting the path from the left ventricle into the ascending aorta (left ventricle outflow tract).

What does chordal Sam mean?

systolic anterior motionChordal 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?

In most patients, LV outflow obstruction occurs via systolic anterior motion (SAM) of the mitral valve in which the elongated leaflets contact the septum in mid-systole due to the high-velocity flow of blood directly on the leaflets.

What is left ventricular outflow tract?

The left ventricular outflow tract (LVOT) is considered represent the region of the left ventricle that lies between the anterior cusp of the mitral valve and the ventricular septum. Its dimensions are often recorded in TAVI work up studies.
