Recurrent Coronary Artery Thrombus Formation in the Setting of Diabetic Ketoacidosis
ABSTRACT: A 34-year-old male with insulin-dependent type II diabetes mellitus developed recurrent ST-elevation myocardial infarction in the setting of diabetic ketoacidosis. In both circumstances, coronary angiography revealed a large thrombus withou…
Coronary Acute Syndrome Due to a Large Occlusive Thrombus in an Aortosaphenous Vein Graft
A 74-year-old male was admitted for acute coronary syndrome. Seven years earlier he had undergone surgery for an abdominal aortic aneurysm and a venous graft bypass to the right coronary artery. At the present admission, the electrocardiogram showed…
Successful Fenestration Using a Chronic Total Occlusion-Dedicated Guidewire in a Patient with Catheter-Induced Dissection of the Right Coronary Artery
ABSTRACT: Guiding catheter-induced coronary artery dissection is a rare, but hazardous complication of percutaneous coronary intervention (PCI) and is associated with the potential risk of impairment of coronary blood flow. Therefore, occurrence of t…
Percutaneous Site-Specific Pharmacomechanical Thrombolysis-Thrombectomy System for Bilateral Acute Limb Ischemia
ABSTRACT: Acute limb ischemia (ALI) remains a life-threatening condition. Studies with catheter-directed thrombolysis and percutaneous mechanical thrombectomy systems show modest improvements in mortality compared to surgery but with pitfalls of majo…
Spontaneous Coronary Artery Dissection: Case Series with Extended Follow Up
ABSTRACT: Spontaneous coronary artery dissection (SCAD) is atherosclerotic or non-atherosclerotic in origin. Eosinophilic infiltrate is identified in coronary artery adventitia in non-atherosclerotic SCAD. We postulate that a systemic inflammatory st…
Effect of Chronic Angiotensin Converting Enzyme Inhibitor Therapy on Myocardial Injury in Patients Undergoing Percutaneous Coronary Interventions
ABSTRACT: Background. Procedural MI is a frequent complication of percutaneous coronary intervention (PCI). Angiotensin converting enzyme inhibitors (ACE-I) have been shown to reduce ischemic events in the setting of acute myocardial infarction (MI)…
Risk Scoring Systems for PCI: Does One Size Fit All?
Predicting outcomes in patients undergoing coronary revascularization has been a topic of long-standing interest. The ACC/AHA (American College of Cardiology/American Heart Association) lesion classification system devised in 1986 and revised in 1990…
Relationship Between the Angiographically Derived SYNTAX Score and Outcomes in High-Risk Patients Undergoing Percutaneous Coronary Intervention
ABSTRACT: Numerous risk scores have been designed to predict the outcome of percutaneous coronary intervention (PCI). The Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score has been shown to predict outco…
Angiographic and Clinical Characteristics of Patients with Acetylcholine-Induced Coronary Vasospasm on Follow-up Coronary Angiography Following Drug-Eluting Stent Implantation
ABSTRACT: Recent studies have shown that drug-eluting stents (DES) induce vascular endothelial dysfunction in both Cypher and Taxus stents. These studies evaluated coronary vasomotion in the peri-stent coronary segment for 1 lesion with 1 DES. The an…
Resolute‚Ñ¢ Drug-Eluting Stent: A Resolution for Bifurcation Lesions?
The treatment of coronary artery bifurcation lesions remains one of the most challenging lesion subsets in interventional cardiology because of a low success rate, a relatively high incidence of procedural complications, greater restenosis rates and…
