The final diagnosis:
An open oval window. Acute violation of cerebral circulation in the right hemisphere of the ischemic type in the basin of the right middle cerebral artery from 07.03.2018. Operation of endovascular closure of an open oval window with implantation of a FigullaFlex II ASD 23/25 mm occluder from 16.05.2018.

At receipt

  • The condition is satisfactory
  • General and biochemical blood analysis, General urine analysis-without features
  • Smad: indicators of the daily blood pressure profile within normal values
  • USDG of brachiocephalic arteries: 25% stenosis at the mouth of the right subclavian artery
  • Consultation with an endocrinologist: it is possible to perform an intervention against the background of taking tyrosol
  • Consultation of a neurologist: Taking into account the ischemic type of onsc against the background of LLC, it is recommended to conduct endovascular closure of LLC to prevent repeated onsc
  • Therapy: acetylsalicylic acid, enteric form 75 mg/day, clopidogrel 75 mg/day, tyrosol 30 mg/day


  • the heart cavities are not enlarged, the walls are not thickened, and the contractility of the myocardium is satisfactory. No areas of violation of local contractility were found. Diastolic function of the LV myocardium is not impaired. There are no signs of pulmonary hypertension. Hemodynamically insignificant valvular regurgitations
  • The MPP swells out into the right atrium cavity up to 0.5 mm, and a bypass blood flow from left to right cannot be excluded.
Open oval window measuring 2 mm.
MPP aneurysm 2.1×0.7 cm.
Resting blood discharge from left to right

Justification for endovascular closure of an LLC

  • It is characterized by ischemic type
  • LLC in combination with aneurysm MPP
  • LLC size 2 mm
  • Whether there is a left-to-right reset at rest
