The Search for Non-invasive Determinants of Response to Ablation of Atrial Fibrillation. Non-invasive Evaluation of Left Atrium Anatomy and Function With Three Dimensional Echocardiography: Comparison With Cardiac CT and MRI

Brief Summary

Detailed Description

This study implies three parts. The first part of the study aims to evaluate the variability and reproducibility of rest two - and three-dimensional echocardiography for the left atrium anatomy and function and to assess their correlation with clinical variables. The second part of the study aims to evaluate the accuracy and reproducibility of the left atrium anatomy and function using echocardiography and to validate it with cardiac CT. Moreover, the study aims to evaluate which parameters can predict the recurrence of atrial fibrillation in patients who have undergone atrial fibrillation ablation. The third part of the study aims to assess the accuracy and variability of echocardiographic measurements compared to cardiac magnetic resonance and to find predictors of recurrence after cryoballoon ablation for atrial fibrillation.
