Background: The benefits of early abciximab administration and thrombus aspiration in ST elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PPCI) have previously been elaborated. However, whether there is an adjunctive effect of thrombus aspiration among STEMI patients, with angiographic evidence of thrombus, receiving early prehospital abciximab remains unclear.

CLINICAL CARDIOLOGY. Electromagnetic Interference and Implanted Cardiac Devices: The Nonmedical Environment (Part I)

Juna Misiri MD, Fred Kusumoto MD and Nora Goldschlager MD

The number of patients with cardiovascular implantable electronic devices (CIEDs), such as permanent pacemakers and implantable cardioverter-defibrillators, is dramatically rising due to an aging population and recent clinical trials showing benefits in mortality and morbidity. Coupled with this increase in the number of patients with CIEDs is the proliferation of technology that emits electromagnetic signals, which can potentially interfere with CIED function through electromagnetic interference (EMI). Despite continuous efforts of manufacturers to create “EMI-proof” CIEDs, adverse events from EMI still occur. Physicians caring for patients with CIEDs should be aware of potential sources of EMI and appropriate management options. This 2-part review aims to provide a contemporary overview of the current knowledge regarding risks attributable to EMI interactions from the most common nonmedical (Part I) and medical (Part II) Clinical Cardiology Volume 35, Issue 5, pages 276–280, May 2012.

CLINICAL CARDIOLOGY. Electromagnetic Interference and Implanted Cardiac Devices: The Medical Environment (Part II)

Juna Misiri MD, Fred Kusumoto MD and Nora Goldschlager MD

Electromagnetic interference produced by medical equipment can interact with implanted cardiac devices such as pacemakers and implantable cardioverter-defibrillators. The most commonly observed interaction is in the operating room with electrosurgery. The risk of interactions can often be mitigated by close communication between the cardiac-device specialist and the anesthesiology/surgical team to develop a patient-specific strategy that accounts for factors such as type of device, type of surgery, and whether the patient is pacemaker dependent. Although magnetic resonance imaging should generally not be used in patients with implanted cardiac devices, several published guidelines provide strategies and recommendations for managing risks if magnetic resonance imaging is required with no suitable diagnostic alternatives. Other common sources of electromagnetic interference in the medical environment are ionizing radiation and left ventricular assist devices. Volume 35, Issue 6, pages 321–328, June 2012.

Objectives: This study sought to develop a 2-dimensional (2D) intravascular near-infrared fluorescence (NIRF) imaging strategy for investigation of arterial inflammation in coronary-sized vessels. Background: Molecular imaging of arterial inflammation could provide new insights into the pathogenesis of acute myocardial infarction stemming from coronary atheromata and implanted stents. Presently, few high-resolution approaches can image inflammation in coronary-sized arteries in vivo. Journal of the American College of Cardiology Vol. 57, No. 25, 2011.

EUROPEAN HEART JOURNAL. Endothelial-dependent vasomotion in a coronary segment treated by ABSORB everolimus-eluting bioresorbable vascular scaffold system is related to plaque composition at the time of bioresorption of the polymer

Aims To analyse the vasoreactivity of a coronary segment, previously scaffolded by the ABSORB bioresorbable vascular scaffold (BVS) device, in relationship to its intravascular ultrasound–virtual histology (IVUS–VH) composition and reduction in greyscale echogenicity of the struts. Coronary segments, transiently scaffolded by a polymeric device, may in the long-term recover a normal vasomotor tone. Recovery of a normal endothelial-dependent vasomotion may be enabled by scaffold bioresorption, composition of the underlying tissue, or a combination of both mechanisms.

NEUROSURGERY. Application of the RELY Study to Lifetime Risks of Atrial Fibrillation: Implications for Spontaneous Intracranial Hemorrhage

Parry, Phillip V.; Engh, Johnathan A.

Atrial fibrillation (AF) is a common arrhythmia that can be found in normal individuals or reflect an underlying structural, metabolic, or infectious abnormality. Medical comorbidities associated with an increased risk for stroke in AF include age > 65 years, hypertension, rheumatic heart disease, prior stroke or transient ischemic attack, diabetes mellitus, congestive heart failure, or an abnormal transesophageal echocardiogram. In addition to beta blockade and cardioversion, formal anticoagulation with vitamin K antagonists, such as warfarin, remains the mainstay of therapy for AF in order to reduce the risk of systemic embolization.1 Drawbacks of warfarin therapy include a substantially increased risk of spontaneous intracranial hemorrhage, an entity all too familiar to most neurosurgeons.

Objectives: This study sought to assess the impact of the SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score (SXscore) on clinical outcomes in patients undergoing percutaneous coronary intervention. Background: The SXscore has been demonstrated to have an ability to predict clinical outcomes in patients undergoing percutaneous revascularization.
