Clinical and angiographic outcomes after coronary artery stenting for acute or threatened closure after percutaneous transluminal coronary angioplasty. Initial results with a balloon-expandable, stainless steel design.
Why the study?
Does coronary artery stenting improve clinical and angiographic outcomes in patients with acute or threatened closure after PTCA?
Population
116 patients with imminent or total acute closure after percutaneous transluminal coronary angioplasty (PTCA)
Design
Case_series
Follow-up
median 14 months (clinical), median 4 months (angiographic)

Implication
May support bailout stenting to avoid emergency CABG after PTCA closure; hypothesis-generating and requires randomized confirmation before practice change.
Structured PICO
Does coronary artery stenting improve clinical and angiographic outcomes in patients with acute or threatened closure after PTCA?
P
Population
116 patients with imminent or total acute closure after percutaneous transluminal coronary angioplasty (PTCA)
I
Intervention
Coronary artery stenting (balloon-expandable, stainless steel design)
O
Outcome
Clinical success (angiographically successful without complications of death, Q-wave myocardial infarction, or CABG) and angiographic success (final diameter stenosis < 50%)composite
Coronary artery stenting for acute closure after PTCA is a feasible alternative treatment that relieves myocardial ischemia and spares a majority of patients from emergency CABG.
Limitations
- Early learning curve experience
