Magnetocardiography detects left atrial dysfunction in paroxysmal atrial fibrillation.

Background: Magnetocardiography (MCG) is a non-invasive technique and to characterize the magnetic field, a pseudo-current conversion was used. The role of MCG in detecting left atrial (LA) dysfunction in patients with paroxysmal atrial fibrillation (PAF) is unknown.

Objective: The aim of this study was to evaluate LA function using MCG in patients with PAF and healthy subjects, to identify possible indices to diagnose PAF.

Validation of magnetocardiography versus fractional flow reserve for detection of coronary artery disease.

Background: Although magnetocardiography (MCG) has been proposed as a non-invasive technique with high accuracy for functional diagnosis of myocardial injury, the validation of MCG against fractional flow reserve FFR in diagnosing coronary artery disease (CAD) has not yet been established. The goal of the study was to determine the diagnostic accuracy of MCG versus invasively determined FFR in patients with suspected or known CAD.

Methods: Forty seven patients with suspected CAD (35 men; mean age 69 years) who underwent coronary angiography and FFR measurement were enrolled.
