Safety and Efficacy of Periprocedural Apixaban Use for Reduction of the Risk of Cerebrovascular Events in Patients Undergoing Ventricular Tachycardia Radiofrequency Catheter Ablation

Ventricular tachycardia (VT) or fast heart rhythm is a condition where the lower chambers
(ventricles) of the heart beat too fast. This condition can be life threatening because these
ventricles are the main pumping chambers of the heart. The fast heartbeat is caused by
electrical impulses that travel incorrectly in your heart.

One way to treat VT is to have a catheter ablation procedure. A catheter ablation is a
procedure that creates scar tissue in the heart to interrupt the electrical impulses that
create irregular heart rhythms.

It is possible that the ablation procedure might cause a blood clot to form. The blood clot
can stop blood flow to the brain and cause a stroke. When blood flow is interrupted to a
certain part of the brain, that part does not receive enough oxygen. As a result of the
stroke the affected areas of the brain are unable to function normally.

Apixaban (also known as Eliquis) is a blood thinning drug, also called an anticoagulant. It
interferes with the body's natural blood clotting ability by inactivating a specific enzyme
that the body needs to form blood clots.

Participation in this study will last about 30 days.

Inclusion Criteria:

duration of treatment with Apixaban plus 33 days post-treatment completion

- Males who are sexually active with WOCBP must agree to follow instructions for
method(s) of contraception for the duration of treatment and for a total of 93 days
post-treatment completion
