Surgical Standby for Coronary Balloon Angioplasty

JAMA: The Journal of the American Medical Association, 1992
To assess the predictability of need for emergency surgery after coronary balloon angioplasty.Nonrandomized intervention study.Nonprofit university hospital.Prior to balloon angioplasty, 1000 consecutive patients were assigned to either the "standby" group (189 patients [19%]) or the "no-standby" group (811 patients [81%]).

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.

Coronary Atherectomy: An Alternative to Balloon Angioplasty

AORN Journal, 1991
To date, physicians at our hospital have performed coronary atherectomy on 15 patients. Of these patients, four needed open heart surgery. One patient needed surgery because a vessel was dissected during the procedure, and the three other patients had unsuccessful procedures.

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 ...

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.

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,

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.

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.
