Coronary stenting in small vessels

Angiographic and clinical outcome following coronary stenting of small vessels: a comparison with coronary stenting of large vessels.

OBJECTIVES Stent implantation reduces restenosis in vessels > or =3 mm compared with balloon angioplasty, but few data are available for stents implanted in vessels <3 mm. The aim of this study was to evaluate immediate and follow-up patient outcomes after stent implantation in vessels <3 mm compared to stent implantation in vessels > or =3 mm. METHODS Between March 1993 and May 1996, a total...

Stenting for small coronary vessels: a contestable winner.

Stents were initially used to manage or prevent acute vessel closure after percutaneous transluminal coronary angioplasty (PTCA). The first direct randomized comparison with respect to restenosis showed the superiority of stenting to PTCA for de novo lesions situated in native vessels 3 mm or larger (1,2). In these trials, stenting was associated with a 25% to 30% reduction of restenosis as com...

Coronary stenting versus balloon angioplasty in small vessels: a meta-analysis from 11 randomized studies.

OBJECTIVES A meta-analysis of 11 randomized trials was done to compare stenting versus balloon angioplasty (BA) in small coronary vessels. BACKGROUND Randomized studies on coronary stenting (CS) in small vessels have yielded controversial results. METHODS Eleven randomized trials on CS versus BA in small vessels, including angiographic re-evaluation at six months, were analyzed. RESULTS T...
