AimsThe aim of this study was to evaluate the relationship between coronary flow reserve and the recovery of wall motion contractility in patients with recent myocardial infarction.Methods and ResultsNineteen patients (55+/-8 years) undergoing balloon angioplasty for recent myocardial infarction were studied. After angioplasty, coronary flow reserve was lower in the infarct-related artery than in...
The annular balloon catheter (Nycomed Medical System, Paris, France) is a new rapid exchange system for local drug delivery to the vessel wall, while maintening distal blood flow. The inflatable part of the device is made of a single preformed helically tube having variable pitch and variable diameter. Over the spires a membrane is fixed which defines an anular leaktight infusion chamber with the...
Background: Event free survival after coronary angioplasty seems to be related to coronary reserve and to residual stenosis (Debate 1).Methods: In order to precise the respective place of stent and Doppler wire in angioplasty we investigated 59 pts (aged 58 +/- 11) with a single lesion dilatation (28 LAD, 11 LCX, 22 RCA). Stenosis (MLD) and CFR (Flowire, IC 18 μg adenosine) were measured at baseline,...
