Complex Angioplasty & Stenting
Reopening arteries others call untreatable
Medically reviewed by Dr Kunal Ajay Patankar, DrNB (Cardiology)
What it is
Angioplasty (PCI) reopens narrowed or blocked coronary arteries using a balloon, and usually a drug-coated stent to keep the artery open. 'Complex' angioplasty refers to the most challenging cases — total blockages (CTOs), heavily calcified vessels, left main disease, and bifurcation lesions.
These procedures demand advanced techniques — rotational atherectomy or intravascular lithotripsy for calcium, specialised wires and imaging guidance — and the experience to use them judiciously.
Who needs it
- Significant blockages found on angiography
- Ongoing angina despite optimal medications
- Heart attack — as emergency (primary) angioplasty
- Chronic total occlusions previously deemed untreatable
- Patients declined for or unwilling to undergo bypass surgery
How it happens, step by step
1
Access & imaging
Like angiography, the procedure is done through the wrist under local anaesthesia. Intravascular imaging (OCT/IVUS) frequently guides sizing and strategy.
2
Lesion preparation
Calcified or resistant plaque is prepared using specialised balloons, rotational atherectomy, or intravascular lithotripsy so the stent can expand fully.
3
Stent deployment
A drug-eluting stent is positioned precisely and expanded. Imaging confirms full expansion and perfect apposition to the vessel wall.
4
Final assessment
Flow, stent expansion and edges are verified — often with a final imaging run — before the catheter is removed.
Recovery, honestly
- Typically 1–2 days in hospital for planned procedures
- Walking within hours; most desk work within a week
- Dual antiplatelet medication is critical — never stop it without cardiology advice
- Cardiac rehabilitation is strongly recommended after stenting
Common questions
How long does a stent last?
Modern drug-eluting stents become part of the artery wall and are designed to last a lifetime. Keeping risk factors controlled protects both the stent and the rest of your arteries.
Will I feel the stent?
No. The stent is a few millimetres of fine metal mesh — you cannot feel it, and it does not set off airport metal detectors.
Angioplasty or bypass — which is better?
It depends on the pattern of disease, diabetes status, heart function and your preferences. I discuss every complex case against current guidelines — and refer for surgery when that genuinely serves you better.
What is a CTO?
A chronic total occlusion — an artery that has been fully blocked for months. Dedicated techniques now allow us to reopen many CTOs through the wrist, relieving angina that medications couldn't.
