Higher balloon dilatation pressure in coronary angioplasty
American Heart Journal, 1984The 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.

Applicability of laser to assist coronary balloon angioplasty
American Heart Journal, 1985Severe 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 ...

Significance of balloon imprint during coronary angioplasty
Catheterization and Cardiovascular Interventions, 2001AbstractBalloon 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

Hugging balloon angioplasty of right coronary artery
Catheterization and Cardiovascular Diagnosis, 1995AbstractWe 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.

Effect of inflation pressures on coronary angioplasty balloons
The American Journal of Cardiology, 1986It 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 ...

Balloon angioplasty of coronary bifurcation lesions: The kissing balloon technique
Catheterization and Cardiovascular Diagnosis, 1986AbstractInitial experience with the technique of “kissing balloon” angioplasty is described in 52 patients undergoing coronary angioplasty. Guiding catheters employing both the femoral and brachial approach were used in all but two of the coronary angioplasties and, in addition, the bilateral femoral approach was used in the renal and peripheral ...

Long-Term Results of Coronary Balloon Angioplasty
Annual Review of Medicine, 1991Long-term results after coronary balloon angioplasty are characterized by an eventful early period up to six months, with about a 30% recurrence rate per lesion, and by a stable situation thereafter. Myocardial infarction due to the dilated site is extremely rare during follow-up because the smooth, elastic, inner lining of a restenosis is much less ...

Survey of Anesthesiology, 1998
Intracoronary stenting reduces the rate of restenosis after angioplasty in patients with new coronary lesions. We conducted a prospective, randomized, multicenter study to determine whether intracoronary stenting, as compared with standard balloon angioplasty, reduces the recurrence of luminal narrowing in restenotic lesions.A total of 383 patients who

Rotational coronary atherectomy after unsuccessful coronary balloon angioplasty
The American Journal of Cardiology, 1993The 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

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.
