The optimal management of patients with ST-elevation myocardial infarction (STEMI) has been the subject of ongoing clinical investigations for the past several decades. When it became apparent that primary angioplasty was not only feasible, but superior, to thrombolytic therapy in randomized clinical trials,1 there was universal adoption of primary percutaneous coronary intervention (PCI) for those centers that perform PCI. The belief that primary PCI was superior to thrombolytic therapy as the initial treatment of STEMI is so strong that many centers that previously administered thrombolytic

X-Ray Angiography and Magnetic Resonance Imaging to Distinguish Interarterial from Septal Courses of Anomalous Left Coronary Artery: An Ex Vivo Heart Model
ABSTRACT: Objective. We sought to demonstrate the distinguishing features between interarterial and intraseptal courses of an anomalous left coronary artery from the right sinus of Valsalva (RSV) on X-ray angiography, using an ex vivo model. Background. An anomalous left main coronary artery (LMCA) arising from the RSV can take prepulmonary, retro-aortic, interarterial (IA) or intraseptal (IS) courses, of which only the IA cours

Avoiding Intelligence Failures in the Cardiac Catheterization Laboratory: Strategies for the Safe and Rational Use of Dalteparin or Enoxaparin during Percutaneous Coronary Intervention
ABSTRACT: Low-molecular-weight heparin (LMWH) has been a mainstay for the management of acute coronary syndromes (ACS) for almost a decade. However, several recent developments have seriously threatened the prominence of this drug class: (i) the adoption of an early invasive strategy, frequently leading to percutaneous coronary intervention (PCI) where the dosing and monitoring of LMWH is unfamiliar

Late-Acquired Stent Malapposition after Sirolimus-Eluting Stent Implantation following Acute Coronary Syndrome: Angiographic, IVUS, OCT and Coronary Angioscopic Observation
ABSTRACT: Drug-eluting stents (DES) have been shown to significantly reduce the incidence of restenosis and target lesion revascularization in a wide variety of clinical situations. DES have also been shown to significantly reduce neointimal hyperplasia as compared to bare-metal stents. However, the antiproliferative properties of DES also delay vascular healing and have been associated with stent malapposition,

Case Description. A 24-year-old male without coronary risk factors came to our office for recent-onset exertional angina associated with shortness of breath. His medical history was notable for Kawasaki’s disease at the age of two. A stress test showed anterior ischemia. Subsequently, he underwent computed tomography (Figure 1) and coronary angiography, which revealed a calcified tubular narrowing of the proximal left anterior descending (LAD) and chronic total occlusion in the proximal right coronary artery (RCA), with bridge collaterals (Figures 2A and B). Optical coherence tomography (OCT
