[Approximation of mathematical scanning simulation data and clinical results f radiofrequency ablation of perimitral atrial flutter. Condition of existence of perimitral atrial flutter].

Aim: 1) to create Perimitral Atrial Flutter (PMAFL) model and estimate theoretical probability of elimination of perimital reetntry using left atrial geometry two-dimensional mathematical modeling and ablative formatting; 2) to compare clinical results of PMAFL ablation by means of mitral vs inferioseptal isthmus ablation and mathematical modeling data.

Material And Methods: Clinical phase. Study was conducted on 24 pts (6 women, 57.

[Successful restoration by radiofrequency ablation and maintenance of sinus rhythm in a patient with longstanding (for 21 years) persistent atrial fibrillation].

Clinical observation of a patient with atrial fibrillation persisting throughout 21 years is presented with discussion of results of radiofrequency catheter ablation.

[Long-term results of radiofrequency catheter ablation of long-lasting persistent atrial fibrillation: five years of follow-up].

Aim: To evaluate long-term results of radiofrequency catheter ablation (RFA) vs. rate-control strategy in patients with long-lasting persistent atrial fibrillation (AF) METHODS: We assessed 5-years results in 66 patients (53.3+/-12.

[Comparison of the effectiveness of pulmonary veins isolation vs linear radiofrequency ablation in paroxysmal atrial fibrillation patients using either mathematical scanning or clinical approach].

Aim: to compare clinical results of linear ablation vs. PVI approach in patients with paroxysmal AF and to estimate theoretical probability of 4-waves re-entry to eliminate as a results of the both ablative techniques formatting by means left atrial geometry two-dimensional mathematical modeling.

Material And Methods: Clinical phase.
