Postoperative pericardial effusion is frequent and can be complicated by cardiac tamponade. Although the different drainage techniques are well described in the setting of medical effusion, there is not a standard postoperative effusion treatment. The aim of this work was to assess the feasibility and effectiveness of the percutaneous pericardial drainage. ⋯ Percutaneous pericardial drainage is effective to treat postoperative pericardial effusion. When the effusion is thicker than 10 mm and accessible, it can be the initial strategy and surgical drainage can serve as an alternate strategy in case of failure and complications of this procedure.

Higher rates of adverse cardiac events have been observed in patients with small vessel disease. Therefore, we compared an everolimus-eluting stent (EES) to a paclitaxel-eluting stent (PES) for treatment of small (reference vessel diameter: RVD <2.5 mm) and larger vessels (≥2.5 mm) in a pooled analysis from the SPIRIT III (n = 1,002) and SPIRIT IV (n = 3,687) trials (randomized 2:1, EES vs. PES). ⋯ In high-risk patients requiring percutaneous coronary intervention in small coronary arteries, EES results in significantly improved 1-year rates of event-free survival compared to PES, with evidence present for both enhanced safety and efficacy.

We describe a case of acute left main stem occlusion complicating a transcatheter transfemoral aortic valve implantation. We treated this emergency using the balloon anchoring technique to insert and implant a stent in the left main stem. Transcatheter transfemoral or transapical aortic valve implantation (TAVI) is a promising treatment in patients with severe, symptomatic surgically nonamenable patients. ⋯ However, TAVI has also been associated with new types of procedure-related complications such as valve embolization and cardiac perforation. Here, we describe a case of acute occlusion of the left coronary main stem following transfemoral TAVI. We treated this emergency using the balloon anchoring technique to insert and implant a stent in the left main stem.

Primary percutaneous coronary intervention (PPCI) is the choice reperfusion strategy for acute ST-segment elevation myocardial infarction (STEMI). However, data on PPCI in elderly patients are sparse. This study determined clinical outcome post-PPCI in elderly versus younger patients with STEMI. ⋯ In a contemporary population of STEMI patients treated with PPCI, overall in-hospital MACE and mortality remain higher in elderly compared to younger patients. Although partly due to higher burden of preexisting comorbidities, a higher DBT may also be responsible. (J Interven Cardiol 2011;24:357-365).

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.
