Introduction Figure 1. Open irrigated catheter, with pores for flow of heparinised saline seen on the tip Susceptibility to stroke is increased around the time of catheter ablation; with ablation of atrial fibrillation (AF) being the most prevalent electrophysiological procedure and, thus, the most studied. Pre-ablation of AF, there is an increased risk of thrombus formation in the left atrial appendage; with potential for embolisation during restoration of normal sinus rhythm.1 During ablation, the risk of thromboembolism is accounted for by endothelial injury, hypercoagulability due to contact of blood with foreign surfaces and altered blo
