Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This study is a single-center, prospective cohort study to investigate non-invasive method to assess left ventricular diastolic function using echocardiography. Patients with AF who are referred radiofrequency catheter ablation (RFA) will be included prospectively. Transthoracic echocardiography will be performed during, immediately before RFA and with no cardiovascular medication taken between the exams so that the loading conditions during catheterization and echocardiography are as similar as possible. We will validate previously proposed echocardiographic parameters and creat an algorithm to identify the relationship between echocardiographic parameters of diastolic function and invasively measured LA pressure in patients with atrial fibrillation.
