IVUS Test in Hyderabad — Intravascular Ultrasound at Yashoda Hospitals, Hitech City

IVUS (Intravascular Ultrasound) is an advanced cardiac imaging technique that places a miniaturised ultrasound probe inside a coronary artery — providing real-time cross-sectional images of the vessel wall from the inside. Unlike a standard coronary angiogram that shows only the silhouette of the artery, IVUS reveals the exact composition, thickness, and distribution of plaque within the wall — and crucially, confirms whether a placed stent is fully expanded and correctly positioned. Dr. Bhishma Chowdary performs IVUS-guided angioplasty at Yashoda Hospitals, Hitech City, Hyderabad for patients across Hitech City, Hitech City, Manikonda, Kondapur, and the wider Hyderabad region.

At a glance

What it is Miniaturised ultrasound imaging performed from inside the coronary artery, providing detailed cross-sectional images of the vessel wall and plaque.
Also known as Intravascular Ultrasound (IVUS), Coronary Ultrasound, Endovascular Ultrasound.
Compared with Optical Coherence Tomography (OCT), which offers higher image resolution but less tissue penetration than IVUS.
Used during Coronary angioplasty procedures before, during, and after stent placement to optimise treatment outcomes.
What it shows Plaque burden, calcium distribution, vessel dimensions, stent expansion, stent apposition, and overall coronary artery anatomy.
Why it matters Under-expanded stents are associated with a significantly higher risk of stent thrombosis and restenosis. IVUS helps ensure optimal stent sizing and deployment.
Available at Yashoda Hospitals, Hitech City, serving patients from Hitech City, Manikonda, Kondapur, Madhapur, and surrounding areas.
Performed by Dr. Bhishma Chowdary, DM Cardiology, Interventional Cardiologist.

What is IVUS and why is it used during angioplasty?

During a standard coronary angiogram, contrast dye fills the inside of the artery and X-ray shows its silhouette — like a shadow. This tells us how narrow the artery is but nothing about what is inside the wall. IVUS changes this fundamentally. A catheter with a rotating ultrasound transducer at its tip is advanced into the coronary artery. Sound waves emitted by the transducer bounce off the artery wall and surrounding structures — generating a 360-degree cross-sectional image of the vessel at every point along its length as the catheter is slowly pulled back.

This reveals the true picture: how thick the plaque is, whether calcium is present and how deep it extends, what the vessel's actual diameter is — not just the lumen diameter visible on angiography — and after stent deployment, whether the stent is fully expanded against the wall or has gaps (malapposition). Each of these factors directly influences whether a stent will remain patent long-term or develop complications.

Why IVUS changes outcomes

Multiple large studies — including the ADAPT-DES registry (8,500 patients) and the ULTIMATE trial — have shown that IVUS-guided stenting reduces the risk of stent thrombosis and target vessel failure by 30 to 60% compared to angiography-guided stenting alone. The benefit is greatest in complex lesions — long stents, calcified vessels, left main stenting, CTO-PCI, and bifurcation lesions.

What IVUS shows that angiography cannot

True Vessel Diameter Angiography measures only the lumen (inside channel) of the artery. IVUS visualises the entire vessel wall, including the external elastic membrane, allowing accurate stent sizing based on the true vessel diameter rather than the visible lumen alone.
Plaque Burden and Composition IVUS differentiates between lipid-rich plaque, fibrous plaque, and calcified plaque. Extensive circumferential calcium, which can prevent adequate stent expansion, is identified before intervention.
Calcium Distribution IVUS distinguishes superficial (intimal) calcium from deep (medial) calcium. Understanding the calcium pattern helps determine whether plaque-modification techniques such as rotational atherectomy or laser therapy may be required before stenting.
Stent Expansion Following stent deployment, IVUS measures the Minimum Stent Area (MSA), one of the most important predictors of long-term stent success. Inadequate stent expansion is associated with a substantially increased risk of restenosis and adverse outcomes.
Stent Apposition IVUS identifies malapposed stent struts that are not fully in contact with the vessel wall. Such findings may not be visible on angiography and can increase the risk of stent thrombosis if left untreated.
Edge Dissections Small dissections at the edges of a stent may be missed on conventional angiography. IVUS can detect these abnormalities early, allowing prompt treatment to reduce the risk of acute stent complications.
Left Main Disease Assessment Angiographic assessment of the left main coronary artery can be challenging because of vessel overlap and foreshortening. IVUS is widely regarded as the reference imaging modality for evaluating left main coronary artery disease and guiding treatment decisions.

When does Dr. Bhishma Chowdary use IVUS in Hyderabad?

  • Left main coronary artery stenting — IVUS is mandatory, not optional, for left main PCI given the high-risk nature of the procedure.
  • Heavily calcified lesions — used to assess calcium depth and distribution, helping guide plaque modification strategies before stent implantation.
  • CTO-PCI (chronic total occlusion angioplasty) — confirms true lumen wire position and guides accurate stent sizing in vessels with uncertain calibre.
  • Long stent segments — ensures uniform stent expansion and optimal apposition throughout the entire treated vessel length.
  • In-stent restenosis — identifies the underlying mechanism such as underexpansion, neoatherosclerosis, or malapposition to guide appropriate retreatment.
  • Bifurcation lesions — complex coronary anatomy requiring precise stent positioning and confirmation of side branch ostium preservation.
  • Any case with a suboptimal angiographic result — IVUS can reveal the underlying cause and provide guidance for corrective treatment.

IVUS vs OCT — which is better?

IVUS Penetrates deeply into the vessel wall, allowing visualisation of the full plaque burden and external elastic membrane. Particularly useful in large vessels, heavily calcified arteries, left main disease, and chronic total occlusions. It offers greater tissue penetration than OCT and does not require blood clearance, making it effective in a wide range of flow conditions.
OCT Provides approximately 10 times higher image resolution than IVUS, enabling detailed visualisation of individual stent struts, stent apposition gaps, thin-cap fibroatheromas, and neointimal tissue. OCT requires temporary blood clearance using a contrast flush during image acquisition and is particularly valuable for detailed stent assessment.
When to Use IVUS Preferred for large-vessel PCI, left main coronary interventions, heavily calcified lesions, chronic total occlusions (CTO), cases requiring deep tissue penetration, and situations where adequate blood clearance for OCT is difficult to achieve.
When to Use OCT Preferred for high-resolution assessment of stent deployment, evaluation of thin-cap plaques, investigation of in-stent restenosis mechanisms, and interventions involving smaller coronary vessels.
Combined Use In highly complex coronary interventions, IVUS and OCT may be used together. IVUS assists with pre-stent vessel sizing, plaque characterisation, and calcium assessment, while OCT provides detailed post-stent evaluation of expansion, apposition, and edge integrity.

Frequently asked questions

Is IVUS painful?

No. IVUS is performed through the same catheter system as your angioplasty — you will not feel the ultrasound probe inside the artery. The probe is smaller than the stent delivery catheter and causes no additional discomfort. You remain comfortable with local anaesthesia at the wrist entry site and conscious sedation throughout.

Does IVUS add time to the procedure?

A single-vessel IVUS pullback adds approximately 5 to 10 minutes to the procedure. For complex cases with multiple IVUS runs before and after stenting, the total additional time is 15 to 25 minutes. This is a worthwhile investment — the IVUS data directly determines stent size selection and post-dilatation decisions that affect your long-term outcome.

Why is IVUS not done at every hospital in Hyderabad?

IVUS requires specific catheter equipment, console technology, and operator training to interpret the images accurately. Not all cath labs in Hyderabad are equipped with IVUS consoles, and not all interventional cardiologists have the training to use IVUS routinely. At Yashoda Hospitals, Hitech City, IVUS is integrated into Dr. Bhishma Chowdary's complex PCI programme as a standard tool.

Can IVUS prevent my stent from blocking again?

IVUS-guided stenting has been shown to reduce in-stent restenosis and stent thrombosis rates compared to angiography-guided stenting — particularly for complex lesions. By ensuring the stent is fully expanded, correctly sized, and well-apposed to the vessel wall, IVUS addresses the most common mechanical causes of stent failure. Restenosis from biological neointimal growth is reduced but not eliminated — dual antiplatelet therapy and risk factor control remain essential.

My previous angioplasty was done without IVUS — is that a problem?

Not necessarily. Many strYashodahtforward single-vessel angioplasties in uncomplicated lesions achieve excellent results without IVUS. However, if you had a complex procedure — long stent, calcified artery, left main, or CTO — and are now experiencing recurrent symptoms or in-stent restenosis, IVUS assessment of the stented segment can identify whether underexpansion or malapposition was a contributing factor and guide retreatment.
