Vascular complications after balloon and new device angioplasty.
BACKGROUND Despite their potential advantages, new coronary angioplasty devices may be associated with more frequent vascular complications than noted after standard balloon angioplasty, theoretically due to the larger sheaths and prolonged periods of anticoagulation required by some of these devices. This study sought to identify the incidence, predictors, and clinical outcome of vascular comp...
متن کاملHeme oxygenase-1 genotype and restenosis after balloon angioplasty: a novel vascular protective factor.
OBJECTIVES We investigated the association of the heme oxygenase-1 (HO-1) promoter genotype with the inflammatory response and restenosis after balloon angioplasty. BACKGROUND Heme oxygenase-1, which is induced by balloon angioplasty, can inhibit neointima formation and vascular remodeling. A dinucleotide repeat in the HO-1 gene promoter shows a length polymorphism that modulates HO-1 gene tr...
متن کاملGeometric vascular remodeling after balloon angioplasty and beta-radiation therapy: A three-dimensional intravascular ultrasound study.
BACKGROUND Endovascular radiation appears to inhibit intimal thickening after overstretching balloon injury in animal models. The effect of brachytherapy on vascular remodeling is unknown. The aim of the study was to determine the evolution of coronary vessel dimensions after intracoronary irradiation after successful balloon angioplasty in humans. METHODS AND RESULTS Twenty-one consecutive p...
متن کاملLinkage analysis of neointimal hyperplasia and vascular wall transformation after balloon angioplasty.
Neointimal hyperplasia (NIH), a result of vascular injury, is due to the migration and proliferation of smooth muscle cells through the media and internal elastic lamina leading to vascular occlusion. We used a rat model to find the genetic regions controlling NIH after endothelial denudation in two divergent inbred strains of rats. The Brown Norway (BN) and spontaneously hypertensive rat (SHR)...
متن کاملBalloon-Based Distal Protection Device Improves the Recovery of Left Ventricular Function after Primary Coronary Angioplasty
Background and Objectives:Despite the high success rate of primary angioplasty in cases of acute myocardial infarction (AMI), myocardial reperfusion can frequently be compromised, mainly due to distal embolization, which can be effectively prevented with the use of distal protection devices. The goal of this study was to see whether PercuSurge, a balloon-based distal protection device, could im...
