POBA
Pronunciation: POH-bah
Also written as: POBA — Plain Old Balloon Angioplasty
Basic balloon angioplasty procedure without stent implantation or adjunctive devices.
Full Definition
Plain Old Balloon Angioplasty represents the original percutaneous coronary intervention technique, involving only balloon inflation to dilate stenotic coronary arteries without stent placement or other adjunctive devices. While largely superseded by drug-eluting stents for most applications, POBA remains relevant in specific clinical scenarios such as small vessel disease, in-stent restenosis treatment, or when anticoagulation is contraindicated. The procedure carries higher rates of acute closure and restenosis compared to stent-based interventions, but offers advantages in certain anatomical or clinical situations where stent implantation may be inappropriate.
Usage
Usage note: Specify when no stent is placed to distinguish from routine balloon pre-dilatation.
