Brief Summary

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

The WATCHMAN FLX Pro European registry is intended to gather real world clinical data for patients undergoing left atrial appendage closure (LAAC) with the WATCHMAN FLX™ Pro device. In a subregistry with approximately 300 patients, it is intended to use the VersaCross Connect™ LAAC Access Solution.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

WATCHMAN FLX Pro

This arm is intended to gather real world clinical data for patients undergoing left atrial appendage closure (LAAC) with the WATCHMAN FLX™ Pro device.

Approximately 300 patients undergo the LAAC procedure in conjunction with the use of the VersaCross Connect™ LAAC Access Solution.

Group Type OTHER

Left atrial appendage closure

Intervention Type DEVICE

The WATCHMAN FLX Pro LAAC Technology is intended to prevent thrombus embolization from the left atrial appendage and reduce the risk of life-threatening bleeding events in adult patients with non-valvular atrial fibrillation who are eligible for anticoagulation therapy or who have a contraindication to anticoagulation therapy.

The VersaCross Connect™ LAAC Access Solution is indicated for the percutaneous introduction of various types of cardiovascular catheters and guidewires to all heart chambers, including the left atrium via transseptal perforation / puncture.
