Balloon angioplasty of the coronary arteries was first developed in the 1970s as an alternative means of revascularization to coronary artery bypass surgery. A major drawback with balloon angioplasty alone was the high rate of abrupt vessel closure resulting from acute arterial recoil and coronary artery dissection. The introduction of bare metal stents (BMS) in the early 1990s revolutionized p...

Coronary collaterals may not be apparent during routine coronary angiography or during coronary angioplasty as a result of a variety of physiologic and anatomic factors.‘-” The dynamic nature of the collateral circulation has been demonstrated by newly appearing angiographic collaterals during contralateral vessel occlusion.3 An elevated coronary occlusion wedge pressure during angioplasty ball...

Coronary heart disease leads to myocardial infarction and is a major cause of death in the United States. Myocardial infarctions result from atherosclerotic plaque deposits inthecoronary atiefies, ‘educing blood flow through these arteries which supply oxygen and nutrients to the heart muscle. The two major approaches for restoring adequate blood flow are “coronary bypass graft surgery” md “cor...

Periprocedural thrombus formation is not only responsible for one of the most serious complications of percutaneous transluminal coronary angioplasty, acute thrombotic occlusion of the coronary artery, but has also been postulated as the initial trigger of pathophysiological mechanisms leading to restenosis. The latter hypothesis is based on experimental findings showing that thrombin activatio...

There has been a growing trend toward percutaneous coronary angioplasty for complex coronary artery lesions. Stent or guidewire break off or trapping within the coronary artery lumen is a rare complication, but it may have fatal consequences. In such cases, the entrapped device may be removed by either percutaneous route or surgical exploration. Here, we report a patient with guidewire entrapme...

background: combination antiplatelet therapy is a classic treatment for percutaneous coronary intervention (pci) but this therapy increases gastrointestinal bleeding (gib). this study highlights the incidence of related risk factors of gib and endoscopic findings in patients with gib after pci and combination antiplatelet therapy. materials and methods: a standard check list was used to evaluat...

During the past 15 years, clinical experience with catheter interventional treatment in patients with Kawasaki disease, including balloon angioplasty, stent implantation, rotational ablation, and transluminal coronary revascularization, has been gradually increasing. Because the coronary artery lesions in Kawasaki disease involve severe calcifications, the indications or catheter intervention t...

BACKGROUND It has been shown recently that postangioplasty coronary flow reserve and the degree of residual stenosis have a modest predictive value for short- and long-term clinical outcomes after coronary angioplasty. Corrected TIMI frame count (CTFC) is a simple quantitative index of coronary blood flow. Its relationship with Doppler coronary flow velocity and clinical outcome after coronary ...

PURPOSE To compare the cost-effectiveness of surgical and angioplasty-based coronary artery revascularization techniques, in particular, angioplasty with primary stenting. METHODS We used data from the Study of Economics and Quality of Life, a substudy of the Bypass Angioplasty Revascularization Investigation (BARI), to measure the outcomes and costs of angioplasty and bypass surgery in patie...

BACKGROUND Although paclitaxel-coated balloon (PCB) angioplasty is an effective procedure for in-stent restenosis (ISR) after coronary stenting, recurrent ISR after PCB angioplasty still occurs. The aim of this study was to evaluate the predictors of recurrent ISR after PCB angioplasty for ISR.Methods and Results:A total of 157 ISR lesions treated with PCB angioplasty from January 2014 to May 2...
