Localized arterial wall drug delivery from a polymer-coated removable metallic stent. Kinetics, distribution, and bioactivity of forskolin

Autor: Frank Litvack, Eldad Rechavia, Vishva Dev, Thomas L. Dr. Lambert, N L Eigler, James S. Forrester

Publikováno v: Circulation. 90:1003-1011

BACKGROUND Coronary stenting is associated with two major complications: subacute thrombosis and neointimal proliferation resulting in restenosis. Our hypothesis is that the biocompatibility of metallic stents can be improved by coating with a polyme

Improving detection of coronary morphological features from digital angiograms. Effect of stenosis-stabilized display

Autor: M P Eckstein, N L Eigler, James S. Whiting, K N Mahrer

Publikováno v: Circulation. 89:2700-2709

BACKGROUND We have developed a digital display method that stabilizes the motion of a stenosis in sequential frames of a coronary angiogram, allowing it to be scrutinized at high display frame rates. The purpose of this study was to determine whether

967-20 Reduced Thrombogenicity of Nitinol vs Stainless Steel Slotted-Tube Stents in Rabbit Carotid Arteries

Autor: Frank Litvack, Michael C. Fishbein, James S. Forrester, Vishva Dev, Sushil Sheth, N L Eigler

Publikováno v: Journal of the American College of Cardiology. 25(2)

The thrombogenicity of slotted-tube stents made of nitinol or stainless steel (Palmaz Schatz) was assessed in a rabbit carotid artery model. Fourteen nitinol and 8 stainless steel stents (7 mm long single segment stents) were deployed in a carotid ar

Digital angiographic assessment of the physiological changes to the regional microcirculation induced by successful coronary angioplasty

Autor: N L Eigler, Helmut Schühlen, James S. Whiting, A Zeiher, M M Rombach

Publikováno v: Circulation. 90(1)

BACKGROUND Impulse response analysis of digital coronary angiographic images calculates a parameter known as the mean transit time of the microcirculation (Tmicro). This has been shown to accurately assess the regional microcirculatory response to pr

Digital angiographic impulse response analysis of regional myocardial perfusion. Detection of autoregulatory changes in nonstenotic coronary arteries induced by collateral flow to adjacent stenotic arteries

Autor: N L Eigler, James S. Whiting, H Schühlen

Publikováno v: Circulation. 89(3)

BACKGROUND Our study compares the effect of acute proximal stenosis of a coronary artery supplying a myocardial perfusion bed with that of stenosis of an adjacent artery resulting in collateral flow diversion supplied by the same perfusion bed. These

Excimer laser coronary angioplasty of aorto-ostial stenoses. Results of the excimer laser coronary angioplasty (ELCA) registry in the first 200 patients

Autor: B Weinstock, G. O. Hartzler, M Nobuyoshi, W O'Neill, N L Eigler, M Leon, Tsvi Goldenberg, Jr Js Douglas, J Margolis, D Holmes

Publikováno v: Circulation. 88(5 Pt 1)

BACKGROUND Percutaneous transluminal coronary angioplasty (PTCA) of aorto-ostial stenosis has been associated with a lower rate of acute success, a high risk of vessel closure, and late restenosis. The purpose of this report is to document a prospect

Digital angiographic impulse response analysis of regional myocardial perfusion. Estimation of coronary flow, flow reserve, and distribution volume by compartmental transit time measurement in a canine model

Autor: S Gu, A Zeiher, N L Eigler, J M Pfaff, H Schühlen, James S. Whiting

Publikováno v: Circulation research. 68(3)

A system impulse response function that describes the kinetics of radiographic contrast material transit through the coronary circulation was calculated from 175 selective digital angiograms of normal and stenotic arteries in 10 dogs during rest and
