Summary

Atrial fibrillation (AF) is a condition detected as an irregular heartbeat. It is the most common rhythm disturbance worldwide which can lead to significant symptoms and serious health problems (stroke and heart failure). The longer a person has AF, the more difficult it is to restore a normal heart rhythm. Those with continuous AF for longer than a year are described as having longstanding persistent AF (LSPAF). This is the most challenging type of AF to treat and medications are often not effective. Apart from medications patients with LSPAF may be offered a medical procedure to help improve their symptoms. It involves putting a flexible thin tube (catheter) into a blood vessel in the groin and up into the heart to destroy the tissue causing irregular heart beat. This procedure has modest success in improving symptoms in the long term. Recently, keyhole surgery has been used for these patients and evidence shows that it is better than the catheter procedure. However, we do not know how well people are doing beyond one year. Feedback from a patient focus group suggested that knowing the long-term results of these two procedures is important to help them make an informed choice when it comes to treatment. In this study we propose to continue monitoring patients from a randomised clinical trial (CASA AF RCT) who have already had one of the procedures. They have a small heartbeat monitor implanted under the skin with a battery life of around 3 years. We will be able to look at their heart rhythm data for the duration of this period and detect the return of the fibrillation if it happens.
