Abstract Funding Acknowledgements Type of funding sources: None. Introduction Mitral annular disjunction (MAD) was first described more than 3 decades ago as an abnormal atrial displacement the hinge point mitral valve away from ventricular myocardium. MAD associated with arrythmias and sudden cardiac death, yet some studies suggested that presence can be potentially normal physiological function . (1) Purpose Our primary end assessment incidence among cohort prolapse at our center secondary predictors arrythmias(VAs) in cohort. Methods It is observational cross section study where we recruited all patients who were diagnosed to have representing area Upper Egypt, defined distinct separation annulus left wall myocardial continuum, it initially by means transthoracic echocardiography. All patients’ demographics family history (FH) death (SCD) collected,symptoms assessed regard palpitations, shortness breathing, chest pain, pre syncope syncope, data echocardiography including LV internal dimensions, leaflets affection, degree regurgitation, careful ECG analysis done extracting for PR interval, corrected QTc, T wave inversion, PVCs surface 24 hours Holter, MRI parameters late gadolinium enhancement, its distribution systolic curling. Results We analyzed 300 prolapse, 7 % them showed disjunction, 33 female patients, mean age 34 years old, follow up period years, main presenting complain palpitations 66 %, FH SCD noticed 9 cohort, Mean QRS width 81 mseconds, QTc 423 EF 60 distance mm, while LA volume 36 cm3, 80 bileaflet only 19 had 50 fibrosis papillary muscles, curling %.VAs having premature complexes or documented monomorphic tachycardia average burden 10 during a Holter.There positive correlation between Prescence significant P value 0.02, there no arrythmias. Conclusions Incidence MVP population center. Only predictor VAs, ECG, echo couldn`t proved positively correlated VAs.

Mitral Annular Dynamics and Left Ventricular Diastole
Background Though diastolic interrogation of the mitral annulus (MA) using tissue Doppler imaging (TDI) has been quite useful in assessing left ventricular (LV) diastolic function, the relative contribution of the previous cycle MA systolic displacement or velocity components to subsequent LV diastole has not been previously investigated. We therefore sought to determine the association between...
متن کاملMitral annular disjunction in myxomatous mitral valve disease: a relevant abnormality recognizable by transthoracic echocardiography
BACKGROUND Mitral annular disjunction (MAD) consists of an altered spatial relation between the left atrial wall, the attachment of the mitral leaflets, and the top of the left ventricular (LV) free wall, manifested as a wide separation between the atrial wall-mitral valve junction and the top of the LV free wall. Originally described in association with myxomatous mitral valve disease, this ab...
متن کاملMitral annular subvalvular left ventricular aneurysm.
Annular subvalvular left ventricular aneurysm was first reported in 1962. This type of aneurysm usually arises from the annular subaortic or submitral region of the left ventricle. It should be differentiated from the left ventricular false aneurysm, which was caused by myocardial necrosis. The etiology of subvalvular aneurysm remains unclear. We have presented a case of annular submitral left ...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
