Conclusion
The detection of obstruction during HCM is a major issue because it increases the risk of progression to heart failure and doubles the relative risk of cardiac death (2).
SAM is often responsible for mitral insufficiency and it is one of the essential determinants of aortic obstruction in HCM (3).
The obstruction may be associated or aggravated by abnormalities of the mitral and valvular apparatus,
requiring precise mapping of the valve apparatus,
preoperatively (3).
Knowledge of the mechanism of obstruction has therapeutic implications.
In fact,
the septal myomectomy without intervention on the mitral apparatus could lead to less successful results in intrinsic mitral abnormalities.
In our study the obstructive character was noted in 47% of the cases.
Abnormalities of the mitral and sub-valvular apparatus were significantly related to SAM.
It revealed abnormalities of the mitral and valvular apparatus in 80% of cases (3).
The obstruction during HCM is favored by abnormalities of the mitral and valvular apparatus
It is essential that MRI analysis is systematic if this is performed preoperatively because of therapeutic and prognostic involvement.
Multiplanar study allows a complete study of these abnormalities.
