However, the prognostics for quite a few of them can still remain somewhat restrained due to the severity of the symptoms, the great number of hospitalizations and high cost of the treatment. The implants of multisite pacing for the ventricle resynchronization in patients with intra-ventricle conduct disorder represent a whole new choice. The report is on a case of 4 patients out of 6 cardiac resynchronization cases that had late evolutions towards complete normalization of the left ventricle function and the diastolic diameters. DESCRIPTORS: myocardiopathy, cardiac resyncchronization, left ventricle assynchrony, left branch block, congestive heart failure. REFERÊNCIAS BIBLIOGRÁFICAS 1 McAlister FA, et al.

Methods: A prospective non-randomized analysis of 36 patients undergoing surgery for multisite pacemaker implantation due to QRS ≥ 130 ms, severe left ventricular dysfunction, and NYHA functional class III or ambulatory class IV congestive heart failure was performed. Results: Favorable results of resynchronization were obtained with both techniques, with no significant differences in the comparison of the two groups, except for a higher QRS narrowing in the BV group, and a trend of a lower number or hospital admissions in the BV group. When the groups were analyzed separately and compared before and after the procedures, we observed that improvement was much more significant in the biventricular group, as were the more statistically relevant rates. Conclusion: Cardiac resynchronization therapy proved to be an efficient therapy in both groups analyzed, although with more significant outcomes in the biventricular group.
