BACKGROUND The Cutting Balloon is a novel dilatation catheter for coronary angioplasty (InterVentional Technologies Inc). It produces longitudinal, microsurgical incisions in the vessel wall before the actual dilatation. It is assumed that these controlled surgical incisions relieve hoop stress and reduce vessel wall injury and eventually restenosis. However, no clinical indicator to support th...

OBJECTIVE To investigate the long term clinical outcome and cost-effectiveness of stenting compared with balloon angioplasty in patients with acute myocardial infarction. METHODS Patients with acute myocardial infarction were randomly allocated to primary stenting (112) or balloon angioplasty (115). The primary end point was the cumulative first event rate of death, non-fatal reinfarction, or...

PURPOSE This two-part prospective investigation was designed to determine the balloon inflation pressures required to dilate stenoses associated with hemodialysis grafts and evaluate the burst pressures of five different angioplasty balloons. MATERIALS AND METHODS Eighty-nine patients with dysfunctional hemodialysis grafts were enrolled and underwent fistulography. The diagnostic studies reve...

BACKGROUND According to early clinical trials, vascular brachytherapy performed prior to or shortly after angioplasty is very effective in reducing restenosis rates. The purpose of this study was to investigate the effects of a novel radioactive catheter that allows simultaneous balloon angioplasty and beta-particle irradiation in the prevention of restenosis. MATERIAL AND METHODS The balloon...

Geometric remodeling in de novo atherosclerosis and in restenosis after balloon angioplasty constitutes a change in total arterial circumference that, together with plaque growth or neointima formation, determines the lumen of the artery. The heterogeneous nature of arterial obstructions raises the question of whether early and late outcomes (restenosis) of angioplasty are affected by the degre...

n engl j med 373;18 nejm.org october 29, 2015 1786 was a similar trend favoring patency in patients who received statins. Also, treatment with a drugcoated balloon was associated with improved patency over a conventional balloon in both patients receiving statins and those not receiving statins. The beneficial effects of statins may be additive to those of drug-coated balloons. In summary, our ...

an 80-year-old diabetic man with severe aortic stenosis was admitted to our hospital for cardiogenic shock complicating non-st-elevation myocardial infarction. echocardiographic evaluation showed also a severe degree of both left ventricular dysfunction and mitral regurgitation. the patient was initially stabilized with inotropes and mechanical ventilation was necessary because of concurrent pu...

The angiographic and histologic consequences of laser thermal angioplasty were examined and compared with those of conventional balloon angioplasty in an atherosclerotic rabbit iliac artery preparation immediately and 4 weeks after the procedure. Nineteen vessels in 13 rabbits underwent either laser thermal or balloon angioplasty in random order. Laser thermal angioplasty was performed in a tot...
