Tandem balloon catheter for coronary angioplasty

Catheterization and Cardiovascular Diagnosis, 1986
AbstractThe Tandem balloon catheter is a triple lumen steerable catheter for coronary angloplasty with two separately inflatable balloons of different diameters. Indications and results of 26 consecutive patients treated with a Tandem balloon catheter are reviewed. Adequate distal pressure measurements were obtained in 71% of the cases. In ten patients,

Effect of balloon material on coronary angioplasty

The American Journal of Cardiology, 1992
Abstract Myocardial ischemia occurs in the absence of symptoms in a proportion of patients with coronary artery disease, a phenomenon that may reflect disturbed pain responsiveness. 1 Episodes of painless (“silent”) ischemia are frequent even in patients who have angina at other times, 2 suggesting that some features of the ischemic event, rather ...

Kissing balloon coronary angioplasty

The American Journal of Cardiology, 1984
Balloon angioplasty of stenoses involving a bifurcation of coronary arteries carries a significant risk of permanent occlusion of I of the branches. 1 Kissing balloon angioplasty was first described for aortoplasty in the Leriche syndrome. 2 In 1981, Gruentzig introduced it into coronary angioplasty.

Higher balloon dilatation pressure in coronary angioplasty

American Heart Journal, 1984
The advent of improved balloon catheters for percutaneous transluminal coronary angioplasty (PTCA) in 1981 extended the theoretic pressure range available for dilatation from 7 atm to 13 atm. The impact of higher dilatation pressure on results of PTCA was studied.

Hugging balloon angioplasty of right coronary artery

Catheterization and Cardiovascular Diagnosis, 1995
AbstractWe report a case of “hugging balloon” dilatation of a giant right coronary artery using two dilatation catheters, a balloon “on a wire” and a balloon “rapid exchange” systems via a single guiding catheter. The necessity of larger PTCA balloon catheter (>4.0 mm) was stressed.

Balloon Angioplasty in Multivessel Coronary Artery Disease

Mayo Clinic Proceedings, 1983
Coronary angioplasty with use of the balloon catheter was initially performed only in patients with single-vessel coronary artery disease. Most symptomatic patients with coronary artery disease who require revascularization for control of their symptoms, however, have stenoses in more than one major coronary artery.

Applicability of laser to assist coronary balloon angioplasty

American Heart Journal, 1985
Severe atherosclerotic obstructed coronary artery disease (CAD) may preclude passage of a balloon catheter for transluminal coronary angioplasty (TCA). Since lasers have been shown to effectively vaporize CAD plaque, the initial application of laser to effect a lumen large enough to accommodate the angioplasty catheter for further dilatation was ...

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 ...

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 ...

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.
