Objective. Studying of the morphometry indices and contractility of the heart left compartments in the left atrium reduction after prosthesis of a mitral valve.
Materials and methods. Into the investigation 634 consequently operated patients with isolated mitral failure were included, who were surgically treated in Amosov National Institute of Cardiovascular Surgery from the 1st of January to the 1st of January 2007 yr. In all the patients the mitral valve prosthesis was performed. In the left atrium dilatation in 49 (7.7%) patients additionally its reduction was done, using paraanular plication of posterior wall of left atrium with the aim to achieve its size lesser than 5,0 cm.
Results. Of 49 patients, suffering constant form of atrial fibrillation, thromboembolic complications have occurred in 3 (6.1%) while performance of paraanular plasty of left atrium with simultaneous elimination of its auricle. All thromboembolic complications were nonsevere, and a left atrium size did not exceeded 5.5 sm.
Conclusion. The left atrium reduction and elimination of its auricle in the left-sided atriomegaly constitutes a significant element of the result improvement in the mitral valve prosthesis in late period of follow-up.
