We report a 64-year-old Turkish man who presented with unstable angina pectoris. Coronary angiography revealed massive intracoronary thrombus, which completely occluded the distal part of the left circumflex coronary artery. The thrombotic segment and the rest of the coronary tree were free of atherosclerosis. The patient was treated with intravenous tirofiban, a glycoprotein IIb/IIIa inhibitor...
OBJECTIVES In the absence of effective clinical pharmacotherapy for prevention of reperfusion-mediated injury, this study re-evaluated the effects of intracoronary adenosine on infarct size and no-reflow in a porcine model of acute myocardial infarction using clinical bolus and experimental high-dose infusion regimens. BACKGROUND Despite the clear cardioprotective effects of adenosine, when a...
BACKGROUND Intracoronary delivery of cardiosphere-derived cells (CDCs) has been demonstrated to be safe and effective in porcine and human chronic myocardial infarction. However, intracoronary delivery of CDCs after reperfusion in acute myocardial infarction has never been assessed in a clinically-relevant large animal model. We tested CDCs as adjunctive therapy to reperfusion in a porcine mode...
Correspondence to: Dr J RT C Roelandt, Division of Cardiology, Thoraxcenter BD 408, University Hospital Dijkzigt, PO Box 1738 DR Rotterdam, The Netherlands. In a recent survey conducted in 30 centres with large experience in intracoronary ultrasound, three dimensional reconstruction of intracoronary ultrasound was ranked as the technical development with the lowest priority,' suggesting that it...
BACKGROUND AND OBJECTIVES Life-threatening hypotension during percutaneous coronary interventions (PCI) is devastating for the patient and is associated with fatal adverse outcomes. The aim of our study was to assess the usefulness of intracoronary epinephrine in severe hypotension unresponsive to other measures during PCI. SUBJECTS AND METHODS We analyzed the Pusan National University Yangsa...
To enhance detection of ischemia during percutaneous transluminal coronary angioplasty (PICA), unipolar intracoronary electrocardiograms (ECGs) were recorded during PTCA in 25 patients from the tips of guidewires positioned distal to stenoses being dilated. Surface electrocardiographic leads chosen to reflect likely areas of reversible ischemia during PTCA were recorded simultaneously. In 21 of...
Background. Experimental studies have demonstrated that intracoronary platelet aggregation and thrombus formation may induce marked vasoconstriction of epicardial arteries with endothelial injury. Methods and Results. To examine the effects of intracoronary thrombus formation on coronary vasomotor tone of human epicardial arteries in vivo, we studied 15 patients who developed intracoronary thro...
