Percutaneous transluminal balloon angioplasty was performed in five children with coarctation restenosis. After angioplasty the pressure gradient had decreased considerably in four patients. In all patients aortography showed an increase in the diameter of the lumen at the site of the restenosis. All patients were normotensive the day after angioplasty. There were no complications during or aft...

OBJECTIVES The aim of this study was to investigate the relation between coronary atherosclerotic plaque injury and activation of the coagulation cascade. BACKGROUND Thrombus formation after atherosclerotic plaque disruption has been implicated in the pathogenesis of atherosclerosis, unstable angina and myocardial infarction. METHODS Biochemical markers of thrombin generation (prothrombin f...

OBJECTIVES The Asymptomatic Cardiac Ischemia Pilot (ACIP) study showed that revascularization is more effective than medical therapy in suppressing cardiac ischemia at 12 weeks. This report compares the relative efficacy of coronary angioplasty or coronary artery bypass graft surgery in suppressing ambulatory electrocardiographic (ECG) and treadmill exercise cardiac ischemia between 2 and 3 mon...

AIMS Angioplasty of lesions in small coronary arteries remains a significant problem because of the increased risk of restenosis. The aim of this study was to compare the efficacy of elective coronary stent placement and optimal balloon angioplasty in small vessel disease. METHODS One hundred and twenty patients with lesions in small coronary arteries (de novo, non-ostial lesion and reference...

Balloon angioplasty of a severe recurrent coarctation was performed in a 4-month-old injant using an anterograde approach not previously described for this lesion. The entire procedure was performed transvenously. After transseptal entry into the left atrium, the transseptal sheath was placed across the mitral valve and the angioplasty catheter advanced across the recurrent coarctation. Angiopl...

OBJECTIVES We sought to determine the effectiveness of primary angioplasty compared with thrombolysis in clinical practice. BACKGROUND In clinical practice, primary angioplasty for the treatment of acute myocardial infarction (AMI) has not yet been proven more effective than intravenous thrombolysis, nor have subgroups of patients been identified who would perhaps benefit from primary angiopl...

OBJECTIVE To assess the direct and follow up results of balloon angioplasty for aortic recoarctation with respect to the type of initial operation and to determine the midterm effect on systolic blood pressure. DESIGN Prospective study of invasive haemodynamic and angiographic data and non-invasive data on upper body blood pressure. SETTING Tertiary referral centre for paediatric cardiology...

Seventy-four consecutive patients with angina undergoing single-lesion percutaneous transluminal coronary angioplasty were evaluated with high-dose (up to 0.84 mg/kg during 10 minutes) dipyridamole echocardiography test (DET) before angioplasty and when possible, afterward. Angioplasty was clinically or angiographically successful in 63 patients and unsuccessful in 11. Before the procedure, 69 ...

OBJECTIVE To compare patient selection and outcome of coronary angioplasty procedures before and after the widespread availability and use of stents. SUBJECTS AND METHODS Group 1 consisted of 252 consecutive patients and group 2 comprised 389 patients who underwent angioplasty between April 1993 and March 1994, and April 1995 and March 1996, respectively, in a tertiary cardiothoracic centre. ...

Abstract: Angioplasty (Versus Non-surgical distances did not show a greater improvement m the Management) for Intermittent Claudication angioplasty group. At 2 years of follow-up in one trial F.G.R. Fowkes and I.N. Gillespie the angioplasty group were more likely to have a Angioplasty (Versus Non-surgical distances did not show a greater improvement m the Management) for Intermittent Claudicati...
