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.

Excimer Laser Coronary Angioplasty (ELCA): Fundamentals, Mechanism of Action, and Clinical Applications.

The Journal of invasive cardiology, 2020
Laser coronary angioplasty was developed to modify atherosclerotic plaque and help with the acute and longer-term limitations of balloon angioplasty, namely, intimal dissection and restenosis, respectively.

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 ...

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,

Primary percutaneous coronary intervention by drug‐eluting balloon angioplasty: The nonrandomized fourth arm of the DEB‐AMI (drug‐eluting balloon in ST‐segment elevation myocardial infarction) trial

Catheterization and cardiovascular interventions, 2015
To evaluate a paclitaxel drug‐eluting balloon (DEB) only strategy in primary percutaneous coronary intervention (PPCI), aiming at a comparison with bare metal stent (BMS) alone, DEB followed by BMS, and paclitaxel eluting stent (PES), as assessed in the ...

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.

Safety and feasibility of a PAclitaxel-eluting balloon angioplasty in Primary Percutaneous coronary intervention in Amsterdam (PAPPA): one-year clinical outcome of a pilot study.

EuroIntervention, 2014
AIMS In primary percutaneous coronary intervention (PPCI), stenting has been shown to reduce the need for repeat target lesion revascularisation (TLR) compared to balloon angioplasty alone, but did not result in a reduction of recurrent myocardial ...

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.
