Angioplasty with or without stenting can be indicated if there
is insufficient symptom control after cardiovascular risk prevention methods have been implemented. Angioplasty is now
minimally invasive, but is limited in that in may cause insufficient vessel dilatation or it may lead to complications such
as dissection or embolisation. Angioplasty is recommended
only after the benefits of modifying risk factors has been
reinforced, supervised exercise has not led to satisfactory
improvement, and imaging has confirmed that angioplasty is
a suitable option for revascularisation.
