Restenosis After Coronary Balloon Angioplasty

Annual Review of Medicine, 1991
A recurrence of stenosis (restenosis) following successful coronary angioplasty continues to be a frequent problem limiting the long-term efficacy of the procedure. An overexuberant reparative response to the arterial injury induced by balloon dilatation leads to intimal hyperplasia, the major mechanism responsible for restenosis. Although none has yet

Balloon Rupture During Coronary Angioplasty

Angiology, 1986
Out of a total of 1,500 percutaneous coronary angioplasties (PTCA), 55 (3.6%) were associated with balloon rupture. Lesion calcification was noticed in 7 of these 55 patients (12.7%). Balloon rupture occurred at a mean pressure of 10.7 atmospheres. All balloons were retrieved without difficulty. Intimal tears were noted in 18 (32.7%) cases.

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,

Coronary balloon angioplasty, stents, and scaffolds

The Lancet, 2017
Since the first coronary angioplasty on Sept 16, 1977, the field of percutaneous coronary intervention has evolved rapidly. Now marking its 40th anniversary, percutaneous coronary intervention has become one of the most common medical procedures worldwide.

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
