Dr. Mansour's area of research is catheter ablation for atrial fibrillation. He is participating in numerous studies with the objective of finding safer and more effective ways to treat this arrhythmia. Some of the tools he is investigating are the cryoballoon and the LASER balloon for pulmonary vein isolation. Dr Mansour is also involved in NIH-sponsored research aiming at defining the indications for atrial fibrillation ablation and identifying patients groups who will benefit from the procedure and comparing it to pharmacological treatment. Another area of research that Dr Mansour is involved in is stroke prevention for atrial fibrillation using non-pharmacological tools such as the left atrial appendage occlusion device, which may have significant value for patients taking warfarin.
