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...

PURPOSE To assess the extent of early recoil in patients with critical limb ischemia (CLI) undergoing conventional tibial balloon angioplasty. METHODS Our hypothesis was that early recoil, defined as lumen compromise >10%, is frequent and accounts for considerable luminal narrowing after tibial angioplasty, promoting restenosis. To test this theory, 30 consecutive CLI patients (18 men; mean a...

In 1974, at the Medical Policlinic of the University of Zürich, German-born physician-scientist Andreas Grüntzig (1939-1985) for the first time applied a balloon-tipped catheter to re-open a severely stenosed femoral artery, a procedure, which he initially called "percutaneous transluminal dilatation". Balloon angioplasty as a therapy of atherosclerotic vascular disease, for which Grüntzig and ...

Objectives. We hypothesized that atherectomy would be superior to balloon angioplasty for ostial and nonostial left anterior descending coronary artery lesions. Background. Balloon angioplasty of ostial coronary artery lesions has been associated with a lower procedural success rate and a higher rate of complications and of restenosis than angioplasty of nonostial stenoses. Directional coronary...

Angioplasty is a safe and effective way to unblock coronary arteries. During this procedure, a catheter is inserted into the groin or arm of the patient and guided forward through the aorta and into the coronary arteries of the heart. There, blocked arteries can be opened with a balloon positioned at the tip of the catheter. Initially, angioplasty was performed only with balloon catheters, but ...

a. At 5 years (median 34 months), correction of renal artery stenosis (RAS), by balloon angioplasty with or without stenting (no distal protection) has no beneficial effect on blood pressure (BP) compared with medical therapy and is associated with an adverse event rate of 10–25%. (Level I Evidence) b. At 5 years (median 34 months), correction of RAS, by balloon angioplasty with or without sten...

Reperfusion after acute ST-segment elevation myocardial infarction (AMI) remains the cornerstone of the initial therapy. Although reperfusion can be accomplished with either primary angioplasty or fibrinolytic therapy, clinical trial data reveal improved outcome with primary angioplasty. Furthermore, primary angioplasty with coronary stenting results in less repeat revascularization than balloo...

AIM Leukocytes have been implicated in restenosis following percutaneous transluminal coronary angioplasty. We investigated the link between the activated status of circulating neutrophils and restenosis after angioplasty. METHODS AND RESULTS The population of 108 patients with single, de novo lesions located in native coronary arteries were treated with elective balloon angioplasty (n=44) or...

OBJECTIVE To assess the efficacy of arterial duct angioplasty in maintaining adequate ductal patency in neonates with critical pulmonary valve stenosis. PATIENTS Two neonates presenting with cyanosis due to critical pulmonary valve stenosis with severe right ventricular hypoplasia underwent percutaneous balloon dilatation of the pulmonary valve. Despite successful dilatation, both remained cy...
