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,...

Late Sequela of Kawasaki’s Disease: Optical Coherence Tomographic Finding

Jin-Man Cho, MD, Il-Suk Sohn, MD, †Ik-Kyung Jang, MD, PhD

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...

ABSTRACT: Background. Preprocedual C-reactive protein (CRP) has been reported to correlate with in-stent restenosis following bare-metal stent implantation. The aim of this study was to investigate the impact of preprocedural inflammation on neointimal hyperplasia assessed by intravascular ultrasound (IVUS) following everolimus-eluting stent (EES) implantation. Methods. We identified 134 patients meeting the following criteria: 1) patients treated with EES; 2) those with stable or unstable angina; and 3) patients available for high-sensitivity (hs)-CRP before the procedure and volumetric IVUS ...

ABSTRACT: Objective. Our aim was to validate a risk score for new target vessel revascularization (TVR) after bare-metal stent (BMS) implantation. Methods. The risk score was developed in a cohort of patients previously treated with BMS at our institution. This risk score ranges from 0 to 5 points, according to the presence of diabetes mellitus (1 point), reference vessel diameter (> 3.5 mm = 0 points; 3–3.5 mm = 1; 20 mm = 2). Patients included in the validation cohort were treated between January and December 2005. Pati...
