Endovascular prosthetic replacement and correction of heart valves

The minimally invasive endovascular surgical intervention is performed in an operating room under local anesthesia and intravenous anesthesia.

By a surgical team (surgeon, assistant, surgical nurse), for the treatment in case of valvular defects (aortic, mitral, tricuspid, pulmonary artery valve) that require a surgical correction. A representative of the manufacturing company performs the preparation of the valve endoprosthesis on the delivery system in the operating room. A surgeon performs the puncture of the radial artery or the common femoral artery and vein transcutaneously (or a vascular surgeon provides for the arterial access) and injects a contrast agent selectively for the angiographic recording of a valvular pathology and anatomical contours with a PigTail catheter. A lead for the temporary cardiac stimulation is implanted into the right ventricle cavity. The surgery is performed under the constant invasive arterial and venous blood pressure control only. A surgeon introduces an intravascular hydrophilic conductor with the diameter of 0.035’’ through a body opening of the valve and performs the replacement of the conductor using a diagnostic catheter on the stiff guide wire to deliver the valvular endoprosthesis according to the “monorail” system. Balloon valvuloplasty and the use of the devices for protection against distal embolization are applied if there are indications. The valvular endoprosthesis is implanted with cardiac stimulation if needed (heart rate is 120 to 180 beats per minute). Angiography and ultrasound heart monitoring are performed to determine the correctness of the valvular implantation and the necessity of further manipulations. Balloon valvuloplasty of the endoprosthesis is performed if indicated. A surgeon records the end result on the angiograph in various projections and with the ultrasound heart monitoring. After the examination the surgical instruments are removed, except for the temporary pacing lead and the hemostasis of the vascular accesses is performed.

Indications for the procedure: data of the clinical picture, ultrasound of the target organ or CT angiography.

Service duration: 20 to 60 minutes.

Special aspects of service provision

The procedure has age restrictions: over 75 years of age.

Contraindications for the procedure: allergic reaction to contrast agents.

Appointment for the surgical intervention is carried out only after a check-up by a specialist cardiac surgeon of Dobrobut clinic chain.
