DVT After Cardiac Procedure

Patients undergoing electrophysiology studies (EPS) and cardiac ablation procedure for the treatment of cardiac arrhythmias may be at increased risk of deep vein thrombosis (DVT) during or after the procedure, which may lead to pulmonary embolus which can be life threatening. The study will use Doppler ultrasound scanning at 24h and between 10-14 days post EPS and cardiac ablation to assess the incidence of undiagnosed DVT. A positive finding may provide support for a larger clinical trial to assess the benefit of prophylactic anticoagulation post EPS procedure.
