Brief Summary

Hypertrophic Obstructive cardiomyopathy (HOCM) is the most common genetic cardiomyopathy, heterogeneous in phenotype and clinical course. The genotype-phenotype relationship and associated molecular mechanisms are still incompletely understood. In the HOCM milieu, increased energy cost of force production, impairing performance and mitochondrial function, may be associated to patients' genotype and/or phenotype

Conditions

Outcome Measures

Primary Outcomes (2)

  • LVOT obstruction degree in cm by Echocardiography

    The degree of the LVOT obstruction as measured in cm by echocardiography .

    3 months

  • Systolic anterior motion of mitral valve

    The presence of systolic anterior motion of mitral valve as assessed by post-operative echocardiography.

    3 months

Secondary Outcomes (3)

  • Post-Operative complictions

    3 months

  • post-operative general condition

    3 Months

  • Post-operative mortality

    3 months

Study Arms (1)

septal myectomy alone versus septal myectomy

EXPERIMENTAL

The aims of the present study is to: 1. Compare the results of adequate septal myectomy alone versus septal myectomy + mitral repair in patients with HOCM. 2. Effect of mitral repair on outcome of patients with systolic anterior motion that accompanies HOCM.

Other: The Septal myectom

Interventions

The Septal myectomy is the preferred treatment of most patients with HOCM, and many studies have documented relief of symptoms and satisfactory late patient survival after relief of outflow tract gradients. valve repair or replacement may be necessary

septal myectomy alone versus septal myectomy

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • All patients that present with hypertrophic obstructive cardiomyopathy (HOCM) with mean pressure gradient\>50 mm Hg at rest or on provocation
  • HOCM patients with severe mitral regurgitation.
  • HOCM patients with New York Heart Association (NYHA) functional class II to IV despite optimal medical treatment consisting of -blocking agents, calcium channel blockers, or both.

You may not qualify if:

  • Non-obstructive physiological characteristics.
  • Previous MV surgery.
  • Patient with intrinsic pathology of the mitral valve.
  • Patients \<18 years.
