Laboratory of intraoperative diagnostics and treatment of arrhythmias

Lab was founded in the beginning of 2012 by the decision of the director of Bakoulev Scientific center Leo Bockeria. 

Interventional procedures – 1600 per year
Radiofrequency ablations – 600 per year
Atrial flutter and atrial fibrillation ablationn – 300 per year
Device implantation- pacemaker, ICD, CRT – 240 per year 

Surgical Services:

  • Corridor" and "Cox Maze
  • Cox Maze IIIB procedure
  • Open heart electrophysiology and mapping

The main aim of the Lab was to support all open-heart surgery of arrhythmias, mostly Cox-Maze procedures. Since that time we perform about 100 open-heart EPs and mapping procedures annually. Our research workers designed and developed special epicardial patch-electrodes and full algorithm of epi-endocardial mapping in patients with different forms of idiopathic and concomitant atrial fibrillation. We also had a national license on this invention. Catheter ablations and device implantations are another important sides of our work. We perform about 1600+ interventional procedures per year including almost 600 radiofrequency ablations and 240 device (pacemakers, ICD and CRT) implantations. The most frequent arrhythmias in our schedule are atrial fibrillation and flutter. We perform 300+ procedures annually about this heart rhythm disorders.

Our scientific and research work is associated with study of mechanisms of AFib, methods of preoperative, intraoperative and postoperative assessment of atrial function and electrophysiological characteristics of the myocardium and determination of treatment strategies of its various forms.

The most valuable results:

  • We have found, that dominant frequencies and complex fractionated atrial electrograms are more specific to evaluate the epicardial and endocardial substrate of AFib
  • We proved the impact of the degree of fibrotic degeneration of outcome of RFA in AFib patients
  • We designed the method of prediction of AFib in young ATachy patients with catheter ablation of focal impulse areas that are more common to those in AFib
  • We are developing the most adequate and simple stage and hybrid treatment strategy of patients with different atrial tachycardias and AFib

The results of our work were presented via articles in different national and international journals, abstracts, poster and oral presentations in different congresses.
