Long-term analysis of conventional coronary balloon angioplasty and an initial “stent-like” result

Long-term analysis of conventional coronary balloon angioplasty and an initial "stent-like" result. The NHLBI PTCA Registry.

OBJECTIVES We examined the influence of an initial "stent-like" result on long-term outcome in patients in the 1985-86 NHLBI PTCA Registry. BACKGROUND Stent use in selected patients is associated with improved angiographic and short-term clinical outcome; however, due to potential for in-stent restenosis and high costs of stents, there is interest in a strategy of more optimal dilatation to a...

Medium- and long-term outcome after coronary balloon angioplasty.

Cutting Balloon Angioplasty versus Conventional Balloon Angioplasty for In-Stent Restenosis Treated by Intracoronary Radiation Therapy

Background: Cutting Balloon angioplasty (CBA) may be a useful treatment modality for in-stent restenosis (ISR) as it maintains a stable position during dilatation and results in potentially less injury than plain old balloon angioplasty (POBA). The purpose of this study was to compare CBA and POBA with intracoronary radiation therapy (IRT) for in-stent restenosis (ISR). Methods: We selected 157...

Initial and long-term outcome of 354 patients after coronary balloon angioplasty of total coronary artery occlusions.

BACKGROUND Coronary balloon angioplasty of chronic total occlusions is associated with relatively low success rates and a high incidence of restenosis. Whether there is long-term benefit in performing angioplasty of these lesions is unknown. The purpose of the present report was to analyze the long-term outcome of a large series of patients undergoing this procedure. METHODS AND RESULTS A com...

Finite element analysis of balloon-expandable coronary stent deployment: influence of angioplasty balloon configuration.

Today, the majority of coronary stents are balloon-expandable and are deployed using a balloon-tipped catheter. To improve deliverability, the membrane of the angioplasty balloon is typically folded about the catheter in a pleated configuration. As such, the deployment of the angioplasty balloon is governed by the material properties of the balloon membrane, its folded configuration and its att...
