Complete Revascularization of Total Obstruction of Both Subclavian Arteries and Descending Abdominal Aorta by Combined Surgery

The vast majority of symptomatic lesions of the aortic arch involve the subclavian artery.1 Since Bachman and Kim first reported a case of successful subclavian artery angioplasty in 1980,2 percutaneous transluminal angioplasty (PTA) has become a well established treatment modality for patients with atherosclerotic stenosis of subclavian artery.3 Chronic infrarenal aortic occlusion has a broad spectrum of ischemic manifestations, and aortofemoral bypass graft surgery has been considered as a gold standard in the treatment of aortoiliac artery occlusive disease. Total occlusion of both subclavi

Pulmonary Arteriovenous Fistula Discovered After Percutaneous Patent Foramen Ovale Closure in a 27-Year-Old Woman

Patent foramen ovale (PFO) is a common condition with an incidence as high as 25% in the general population.1 In some studies, young patients who present with neurological events show a higher prevalence of PFO and an association with a significant increase in recurrent events.2–4
Over the last few years, there has been a great deal of interest in the percutaneous management of PFO. Recent studies have demonstrated that percutaneous closure is both safe and successful in the treatment of PFO, as well as other intracardiac communications.5–10

Pharmacoinvasive Management of Acute Coronary Syndrome in the Setting of Percutaneous Coronary Intervention: Evidence-Based, Sit

Over the past decade, impressive reductions in mortality, reinfarction and length of hospital stay have been reported in large-scale studies of patients with acute coronary syndrome (ACS). Despite these advances, substantial challenges remain in identifying the optimal combination of therapeutic agents [e.g., low molecular weight heparins (LMWHs) or unfractionated heparin (UFH), ADP receptor antagonists and glycoprotein (GP) IIb/IIIa inhibitors] that will maximize outcomes while minimizing drug-related adverse events in patients with ACS.
As a result of clinical trials published since the Mar

Localized Bronchiectasis is a Definite Association of Coronaro-Bronchial Artery Fistula

Vascular anastomoses between the coronary arteries and the bronchial arteries were found in 22% of normal subjects and in about 48% of patients with significant coronary artery disease (CAD).1 These vascular anastomoses are congenital in origin, usually small and hemodynamically insignificant. Sizable coronaro-bronchial artery fistula (CBF) is rare. It is described in the literature as individual case reports in about a dozen cases.1–14 Because of the limited number of documented cases, the pathophysiology, natural history and clinical presentation remain unclear. The factors governing the o

Oral Rapamycin in the Treatment of Diffuse Proliferative In-Stent Restenosis in a Patient with Small Reference Vessel

Case Report. A 63-year-old man was admitted to our hospital due to recent onset chest pain with radiation to the left arm, which was precipitated by minimum efforts and relieved by rest. He was evaluated at the coronary care unit and treated with aspirin, heparin and intravenous nitroglycerin. The electrocardiogram revealed a T-wave inversion in leads V4, V5, V6, D1, and AVL. His coronary risk factors were diabetes type II treated with an oral hypoglycemic agent, and dyslipedemia treated with statins. He was also a smoker.
Physical examination in the Coronary Care Unit was remarkabl

Percutaneous Repair of Coronary Artery Bypass Graft-Related Pseudoaneurysms Using Covered JOSTENTs

Spontaneous rupture of a saphenous vein graft with pseudoaneurysm formation is a rare occurrence after coronary bypass grafting. Until now, pseudoaneurysm formation from a native coronary artery at the site of a left internal thoracic to radial artery T-graft anastomotic site has not been reported. Although the recommended treatment of vein graft or native coronary artery pseudoaneurysms remains poorly defined, open surgical ligation with placement of a new conduit, percutaneous coil embolization, and now treatment with covered stents are among the therapies reported. We hereby report the use

Benefits of Endovascular Hypothermia on Myocardial Preservation in the Setting of Cardiogenic Shock

Case Report. A 76-year-old female with carotid disease and a previous CVA presented in cardiogenic shock due to an inferior myocardial infarction (MI). Endovascular hypothermia was administered in the emergency room, reducing her body temperature from 98.6 ºF to 91.4 ºF. Attempted percutaneous revasculaization failed secondary to inability to pass a guidewire due to vessel tortuosity. Hypothermic conditions were maintained for three hours following transfer to the ICU. Following extubation on day three she had no residual neurologic deficits, despite protracted hypotension necessit

Anomalous Coronary Artery Arising From the Opposite Sinus: Descriptive Features and Pathophysiologic Mechanisms, as Documented

Coronary anomalies continue to present an arcane puzzle to most cardiologists. We wish to focus on one particularly fascinating type of defect, in which both coronary arteries arise from the same aortic sinus, or an Anomalous Coronary Artery originates from the Opposite (than normal) Sinus (ACAOS). First reported in 1966 by Jokl and associates1 and more extensively discussed in 1974 by Cheitlin2 and Liberthson3 and their colleagues, anomalous origination of the left coronary artery (LCA) from the right aortic sinus is associated with a high risk of sudden death, usually related to strenuous ex
