Current clinical guidelines recommend dual antiplatelet agents namely aspirin and clopidogrel for the treatment of patients suffering from acute coronary syndrome (ACS). But the efficacy of clopidogrel is variable as it is a pro-drug, which has to be metabolized to become an active drug thus exhibiting variable platelet inhibition, increases risk of bleeding, stent thrombosis, and ischemia. ⋯ Finally, a novel reversible and direct-acting oral adenosine diphosphate (ADP) receptor antagonist, ticagrelor was developed that showed consistent and increased P2Y12 inhibition with similar incidence of bleeding but greater reduction in cardiac events compared to clopidogrel. The focus of this article is to review ticagrelor as a new class of P2Y12 inhibitor.

Comparative Study
Percutaneous patent foramen ovale closure using Helex and Amplatzer devices without intraprocedural echocardiographic guidance.
We compared procedural outcomes of patients undergoing patent foramen ovale (PFO) closure using Helex (W.L. Gore & Assoc., Flagstaff, AZ, USA) and Amplatzer (AGA Medical Corp., Plymouth, MN, USA) devices using intracardiac echocardiographic (ICE) versus fluoroscopic-only guidance. ⋯ Use of right atrial angiography and fluoroscopic-only guidance for PFO closure using Helex and Amplatzer devices provides an efficient alternative to ICE guidance. While procedure and fluoroscopy times were significantly shorter for Amplatzer versus Helex cases, these times were similar for Helex comparing fluoroscopy versus ICE guidance.
