Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Atrial fibrillation (AF) is the most common cardiac rhythm disorder in clinical practice. In the last two decades the number of hospitalizations for AF has increased two- to three-fold. More than 6 million people worldwide suffer from atrial fibrillation (AF), a cardiac disorder that results in systemic emboli. Patients with AF are 5 times more likely to have a stroke compared with those without AF.

This registry will collection information on two devices that are used to treat AF. The WATCHMAN and LARIAT. The differences in techniques and subsequent effects of the two devices on outcomes related to AF has not been studied. This study will look to compare the two devices to see how the outcomes may vary.

WATCHMAN

Patients that had the WATCHMAN device implanted

WATCHMAN

Intervention Type DEVICE

The WATCHMAN is an expandable device deployed in the LAA via a trans-septal catheter. The implanted device has a self-expanding nitinol frame to secure it in the LAA. The fabric of the WATCHMAN device is permeable to blood.

LARIAT LAA Device

patients that had LARIAT LAA device implanted

LARIAT LAA

Intervention Type DEVICE

The LARIAT snare device is an over-the-wire device guided over the LAA to enable ligation of the LAA. The LARIAT can be opened and closed as desired for ideal positioning without risk of suture deployment.
