Voka Children Cardiac Surgery

A unique comprehensive database of highly accurate 3D models featuring congenital heart defects (CHD) of all types has been created. We are engaged in the work on Mixed Reality/HoloLens training tool to provide training in the surgeries conducted to correct children congenital heart defects (CHD).

3D Catalog WEB

Database of 3D models of congenital heart diseases with all their anatomical variations.

3D HoloLens Trainer

Mixed Reality / HoloLens Training tool to study and perform training of all types of children cardiac surgeries.

Surgery Assistant

Applying Mixed Reality technologies to resolve most complex congenital heart diseases.

3D Catalog Mobile

Is in development mode, coming soon.

Cardiac

VOKA children cardiac surgery

3D Catalog

Contains 3D models featuring congenital heart diseases with all their anatomical variations as well as concise description of each of them. Such arrangement facilitates study and training processes. 3D catalog is a unique one.

The catalog is being developed for:

Microsoft HoloLens

IOS/Android Mobile

3D Catalog

Watch catalog

3D catalog provides for 26 nosological units being in their turn further split into particular types. All in all the catalog counts more than 100 3D models

Except for regular 3D models of heart diseases the catalog has simplified heart models lacking some outer linings. These models are designed to facilitate the understanding of heart anatomy.

Hemodynamics 3D models are being designed as hemodynamics is central to the natural blood circulation and it dominates in the process of selecting most suitable surgical treatment plan.

Education HoloLens Trainer

VR training tool to study and perform training of all types of children cardiac surgeries.

It features any scenario of a surgery performed to correct a particular heart disorder. User can stop and concentrate at any stage of a surgery, get better understanding of gross anatomy as well as different types of surgeries performed to correct a congenital heart disorder.

Mixed Reality / HoloLens VOKA training tool is being developed for Microsoft HoloLens.

Currently the most popular ways to acquire surgical skills are assisted surgery, being not always possible, text-based information and 2D visualizing. None of them provides a full idea of surgery procedures, and there is no way one can assist during all types of surgeries within a short period of time.

Our solution is the best option developed currently.

Surgery Assistant

Augmented Reality system to visualize CT/MRI data in 3D and to position obtained 3D models on patient's organs thus facilitating the way of surgery conducting.

Hybrid closure of VSD is a procedure implicating both endovascular and traditional surgical treatment performed simultaneously with artificial blood circulation involved. 3D visualization technology is speeding the hybrid closure up making it more precise with less surgical injury as we avoid using X-ray radiation and appearing of pathophysiological aspects.

Hybrid VSD Closure

Procedure that includes simultaneous endovascular and standard intervention in conditions of artificial blood circulation. 3D imaging technology will allow hybrid interventions to be carried out faster, with greater accuracy and less trauma, by eliminating x-rays, and pathophysiological aspects of cardiopulmonary bypass.

Traditional VSD closure procedure using cardiopulmonary bypass

Cannulating aorta, superior vena cava and inferior vena cava

Connecting a patient to artificial blood circulation

Performing cardiac arrest based on cardioplegia

Right atriotomy (atrium exposure)

Visualizing VSD through a tricuspid valve

VSD patching

Stitching of the atrium

Hemostasis

Starting the heart

Decannulating

VSD closure procedure

  • CT examination
  • Processing obtained data
  • Creating animated 3D model
  • Median sternotomy, pericardiotomy
  • Positioning of a 3D model on the patient's heart using AR technology, synchronizing animation with R wave peak (Electrocardiography)
  • Purse-string suturing of the right ventricle
  • Ventricle puncturing with introducer needle
  • Inserting occluder into VSD, its closing
  • Transesophageal echocardiogram to check the autonomy of both tricuspid valve

Method of pulmonary aftery unifocalization

  • CT examination
  • Data processing
  • Creating animated 3D model
  • Median sternotomy, pericardiotomy
