Stenting in acute myocardial infarction (AMI) has the benefits of achieving acute optimal angiographic results and correcting residual dissection to decrease the incidence of restenosis and reocclusion. Studies have shown that percutaneous transluminal coronary angioplasty for primary treatment after AMI is superior to thrombolytic therapy regarding the restoration of normal coronary blood flow...

Background Previous studies have shown the feasibility of peripheral arterial ultrasound angioplasty. Methods and Results In this report, we describe the use of percutaneous therapeutic ultrasound for coronary angioplasty. In vitro, 11 postmortem, atherosclerotically occluded coronary arteries were obtained to assess catheter-delivered ultrasound for arterial recanalization as well as for asses...

Diabetes mellitus, a major determinant of cardiovascular events, portends an adverse prognosis in patients with coronary artery disease regardless of treatment strategy. Among patients undergoing coronary revascularization procedures, the Bypass Angioplasty Revascularization Investigation (BARI) trial (1) demonstrated an unfavorable interaction between diabetes and an initial strategy of percut...

Long coronary lesions are associated with adverse outcomes after percutaneous coronary intervention since the era of plain balloon angioplasty. Long lesion and long stent length are considered as important predictors of restenosis after percutaneous coronary intervention. With the advent of newer generation drug eluting stents, there has been dramatic reduction in the rates of restenosis and re...

PURPOSE The paper presents the process of numerical modeling and simulation of balloon angioplasty of the coronary artery using Finite Element Method. METHODS The authors focused on the issue of applying adequate pressure in an arterial tissue during the post-dilatation process in the "kissing balloon" stenting technique applied to patients with bifurcation stenosis. Despite great progress in...

Although it is commonly believed that ischemia does not develop during coronary intervention in patients with rich collateral circulation to the target vessel, ST changes are often observed, the study group comprised 40 consecutive patients who underwent elective percutaneous coronary angioplasty and who had rich collateral vessels to the target lesions. None had side branches in the target ves...

Background Platelet glycoprotein IIb/IIIa inhibitors are administered during percutaneous coronary intervention as a bolus followed by infusion. The need for an infusion was established by the Evaluation of 7E3 for the Prevention of Ischemic Complications (EPIC) trial conducted during the percutaneous transluminal coronary balloon angioplasty (PTCA) era, when the threat of acute thrombotic comp...

Retrograde dissection of the aorta is a rare but potentially life threatening complication of percutaneous coronary intervention. We describe a case of retrograde aortic dissection, which occurred during attempted percutaneous transluminal coroanary angioplasty (PTCA) of chronically occluded left anterior descending artery (LAD). Emergency coronary artery bypass grafting (CABG) was performed to...

The incidence of coronary artery spasm at the site of previous successful angioplasty and its importance in leading to subsequent restenosis or recurrence of symptoms are unknown. Fourteen consecutive patients with single vessel coronary artery disease who had undergone successful percutaneous transluminal angioplasty were studied. All patients were given ergometrine maleate (ergonovine maleate...
