Surgical Standby for Coronary Balloon Angioplasty

JAMA: The Journal of the American Medical Association, 1992
Objective. —To assess the predictability of need for emergency surgery after coronary balloon angioplasty. Design. —Nonrandomized intervention study. Setting. —Nonprofit university hospital. Patients. —Prior to balloon angioplasty, 1000 consecutive patients were assigned to either the "standby" group (189 patients [19%]) or the "no-standby ...

Significance of balloon imprint during coronary angioplasty

Catheterization and Cardiovascular Interventions, 2001
AbstractBalloon imprint during angioplasty is often seen, but not at all inflations. We prospectively studied 235 consecutive patients undergoing 282 PTCAs during a 4‐month period, who were divided into two groups: those with balloon imprint during inflation (159 patients, 190 lesions; 67%) and those without (76 patients, 92 lesions; 33%). Clinical and

Effect of inflation pressures on coronary angioplasty balloons

The American Journal of Cardiology, 1986
It is a common conception that the balloons used in percutaneous transluminal coronary angioplasty will inflate to a certain designated diameter and maintain this diameter over the wide range of inflation pressures. With use of an optical magnification system, the diameters of multiple angioplasty dilating catheters made of polyvinyl chloride (USCI ...

Loss and retrieval of a coronary angioplasty stent balloon

Cardiovascular Revascularization Medicine, 2013
A case is presented in which a breakage of the coronary stent delivery catheter occurred as retrieval of the stent balloon was attempted after stent implantation. The broken distal balloon shaft with its stuck balloon was retrieved by controlled pulling on the guiding catheter in which a new balloon was inflated, thus trapping the distal shaft.

Rotational coronary atherectomy after unsuccessful coronary balloon angioplasty

The American Journal of Cardiology, 1993
The clinical and angiographic outcome of patients undergoing rotational coronary atherectomy after unsuccessful balloon angioplasty was evaluated using quantitative angiographic methods to provide insight into this procedure's mechanism of benefit. During the study period, 41 patients (50 lesions) were referred for rotational atherectomy after standard

Comparison of coronary angioplasty with compliant and noncompliant balloons (the angioplasty compliance trial)

The American Journal of Cardiology, 1995
Abstract In conclusion, for conventional balloon angioplasty with compliant and noncompliant balloons, quantitative angiographic results, angiographic and clinical complications, and overall procedural outcome are similar.

Cutting balloon angioplasty is superior to balloon angioplasty or stent implantation for small coronary artery disease

Coronary Artery Disease, 2004
The aim of this study is to demonstrate initial results and long-term outcomes of patients after receiving cutting balloon angioplasty (CBA), balloon angioplasty (BA), or stenting for small vessel diseases. We studied a total of 327 lesions of small coronary disease treated either by CBA (n=87), BA (n=130), or stenting (n=110) in two affiliated ...

Hugging balloons: Coronary angioplasty of oversized vessels with side‐by‐side balloons

Catheterization and Cardiovascular Diagnosis, 1988
AbstractAngioplasty of large (<4.0‐mm) saphenous vein grafts using the largest available (4.0‐mm) balloon catheters may result in inadequate graft dilatation. To avoid leaving a significant residual stenosis, two balloon catheters can be inflated side by side across the stenosis. Herein, we report two cases where this “hugging balloon” technique was

[Value of the calibration of coronary angioplasty balloons].

Archives des maladies du coeur et des vaisseaux, 1990
A total of 197 polyethylene balloons of 2 to 4 mm diameter were inflated to 1 to 10 atmospheres to determine the variations of size with respect to pressure of inflation. A linear relationship was observed between diameter and pressure of inflation. The slope of this relationship represents the compliance.

[Histopathological features of balloon coronary angioplasty].

Cardiologia (Rome, Italy), 1995
Balloon coronary angioplasty revascularization is accomplished through a remodelling of the atherosclerotic stenotic wall. Increase in lumen diameter is achieved by plaque cracking with intimal dissection, plaque compression and medial stretching.
