French term or phrase: SAM cordages
Hello,

This is from a Canadian echocardiography report. The patient has moderate mitral regurgitation and the report reads:

"Feuillets mitraux légèrement redondants avec SAM cordages. IM centrale modérée."

SAM should be systolic anterior motion, but this finding relates to the mitral valve, not to the mitral chords. Well, I must be missing something.

Any input is appreciated.

systolic anterior movement of the chordae tendinae
Explanation:
heart.bmj.com/cgi/content/abstract/49/3/234

The mechanism of systolic anterior motion of the mitral valve and the localisation of the intraventricular pressure gradient were determined in 15 cases of hypertrophic obstructive cardiomyopathy by the combined use of real time two dimensional echocardiography and intracardiac manometry. We arrived at the following conclusions. The systolic anterior motion of the mitral echo in the M-mode echocardiogram can be classified into two types, I and II, based on two dimensional echocardiographic findings. In type I, the echo sources of systolic anterior motion are the anteriorly shifted mitral chordae and, in part, the papillary muscles.

Systolic anterior motion of the mitral chordae tendineae: prevalence and clinical and Doppler-echocardiographic features.

The objective of this investigation was to determine the prevalence and clinical associations of systolic anterior motion (SAM) of the mitral chordae (chordal SAM) in patients without evidence of hypertrophic cardiomyopathy. Although SAM of the mitral valve is thought to be a specific marker of hypertrophic obstructive cardiomyopathy, little is known about the clinical significance of chordal SAM either as an isolated echocardiographic finding (ICSAM) or in patients with mitral valve prolapse (MVP).

Le soulèvement antérieur de la valve mitrale(SAM):
En mode TM (Figure 3 ) : le segment d'affrontement systolique des valves est déformé en dôme, il a
été retrouvé dans 61 % des observations étudiées et il existe une relation entre l'amplitude du
gradient de pression intraVG et la durée du contact entre la valve mitrale et le septum
interventriculaire.
Le mécanisme exacte du SAM est inconnu. Certains auteurs supposent qu'un simple effet Venturi est
responsable du SAM tandis que d'autres prétendent que l'effet Venturi n'est qu'en partie responsable
du SAM.
Pourraient jouer un rôle : la malposition de l'appareil mitrale très fréquente dans cette affection un
déplacement des piliers ou un allongement des feuillets mitraux.
La fermeture méso-systolique des sigmoïdes aortiques:
Elle s'observe dans 80 % des cas de CMH avec obstacle à l'éjection.
Dans la CMH avec obstruction, la vitesse maximale du flux d'éjection sous- aortique est augmentée
atteignant 4,1 m/sec (normale<1,5m/s.
Le flux d'éjection est étroit et sa morphologie est caractéristique, à déformation concave vers la
gauche.
Lorsqu'il n'existe pas d'obstacle, on peut faire apparaître cette accélération de la vitesse sous-
aortique par les tests de provocation habituels. Ces tests objectivent le caractère dynamique du
gradient mais ne fournissent aucun élément pronostique.
L'examen transoesophagien (ETO) figure 5 peut faciliter la distinction entre une CMH avec obstacle et
une sténose sous-valvulaire. Il permet aussi d'étudier l'appareil sous-valvulaire mitral, la longueur des
cordages et la partie de la valve mitrale participant au SAM, la chronologie de l'IM. Le Doppler à
codage couleur est aussi une méthode utile pour analyser la répartition spatiale des hautes vélocités
et permet aussi de différencier facilement le flux d'accélération sous-aortique de celui d'une
régurgitation mitrale. Le flux aortique est difficilement accessible par voie apicale du fait de
l'hypertrophie septale et de la désaxation de la cavité VG et ne peut être étudié dans la plupart des
cas que par l'incidence suprasternale.
Le pic de vitesse aortique (figure 6) est moins élevé que celui de la vitesse sous-aortique : 1,4 m/sec
vs 4,1 m/sec. en moyenne. En l'absence d'obstruction, le temps d'éjection est normal(277 + 21 vs
270 + 25ms) mais en sa présence il est prolongé (321 + 26ms).

So

It would appear that "SAM" can = anterior motion of the mitral valve OR "systolic anterior motion" of the mitral valve. So they must be one and the same thing...
