Treatment of chronic total occlusions (CTO) produces more difficulties, angst and trepidation than any other lesion subset in interventional cardiology. Many of the difficulties stem from: difficulty engaging the occlusion, chronicity of the occlusio…
Clopidogrel bisulfate is a thienopyridine oral antiplatelet agent that acts via irreversible inhibition of adenosine diphosphate-mediated platelet activation and aggregation.1 It is widely used in the treatment and secondary prevention of a variety o…
A 66-year-old male presented with exertional dyspnea and palpitations. The electrocardiogram showed atrial fibrillation and episodes of atrial flutter. Subsequent echocardiography revealed signs of right-sided heart failure with dilatation of the rig…
To the Editor: Percutaneous coronary interventions of thrombotic or friable lesions, such as in acute myocardial infarctions, can often result in distal embolization. To circumvent this problem, modern techniques frequently involve pretreatment with…
Dear Readers, This issue of the Journal of Invasive Cardiology includes several interesting articles selected for their importance to the care of cardiac patients. The first research article, submitted by Dr. Ilias Mylonas and collea…
Percutaneous treatment of coronary chronic total occlusions (CTOs) remains one of the major challenges in interventional cardiology. Recent data have shown that successful percutaneous recanalization of coronary CTOs results in improved survival as w…
Interatrial transseptal catheterization is a technique commonly used in the electrophysiology laboratory to access the left atrium. The procedure is being used more commonly as ablation of atrial fibrillation is more widely applied. Traditionally, tr…
Pericardial effusions can result from various clinical entities. Occasionally, pericardial effusion may result in cardiac tamponade requiring immediate drainage. In some patients, especially those with malignant pericardial effusions, the effusions m…
Stent thrombosis is defined as acute thrombotic occlusion in the stented segment of a coronary artery, usually presenting as ST-segment elevation myocardial infarction,1 and typically occurs within the first several weeks after stent placement. Stent…
Case Report. A 59-year-old male with exertional angina pectoris had undergone coronary angiography in 1998. Selective left coronary angiography showed that his left anterior descending artery (LAD) was totally occluded at the proximal site without an…
