Treatment of atrial fibrillation: magnetic resonance imaging to help forecast

Researchers have developed a method based on magnetic resonance imaging of the new therapy for the detection and assessment has undergone a treatment of patients with atrial fibrillation in the left atrium wall.

Atrial fibrillation is a type of abnormal heart rhythm (arrhythmia). Currently effective in the treatment of atrial fibrillation is RF current ablation therapy: a mild painless current PLEI removed carefully selected heart muscle cells to prevent the transmission of these muscle cells stimulated additional ECG.

To date, there is no accurate non-intervention approach can be used to accurately assess the scars left atrium, in charge of research about Nassir F. Marrouche, we have developed a novel method of magnetic resonance technology to detect and assess the scope of the scars of the left atrium and potential to predict RF current ablation is successful.

The study's researchers have developed a technique without intervention, called delay increases cardiovascular magnetic resonance, the technology used by people with atrial fibrillation patients left atrial RF current ablation therapy before and after the creation of 3-dimensional image.

This harm organizations rebuild model can rebuild RF current ablation therapy in RF energy is applied to the relevant area and, therefore, can reflect on the scar tissue. The researchers also found that the left atrium wall surgery damage ratio lower patients more likely to avoid arrhythmia, and recommended that the size of the SCAR and the surgery was successful linkages between.

The new imaging technology and analysis can help physicians improve RF current ablation therapy program, so that he more readily to identify what is needed to remove the heart muscle cells.

And remove the heart muscle cells will likely reduce the recurrence of atrial fibrillation.

The 3-dimensional magnetic resonance benefit lies in the ability to render full left atrium room wall, Marrouche talked about, and he is safe and non-Interventional so it can be repeatedly used on patients without causing significant risks
