  • IVUS Guided Angioplasty in Kolkata: 5 Vital Secrets for Safety

    Introduction

    You are getting a stent placed in your heart. You want it to last forever. But did you know that standard angiography (X-ray) is just a “Shadow”? It only shows 2 dimensions of your 3D artery. Because of this, many stents are placed “undersized” or “under-expanded,” which leads to failure later. IVUS Guided Angioplasty in Kolkata

    Dr. Avishek Saha, a certified imaging specialist, explains IVUS Guided Angioplasty in Kolkata—using sound waves to see inside the wall of your artery, ensuring your stent is perfect.

    1. X-Ray vs. Ultrasound (The Blind Spot) IVUS Guided Angioplasty in Kolkata

    Imagine trying to park a car in a tight spot with one eye closed. That is Angiography.

    • The Limit: X-ray shows the lumen (the tunnel), but not the wall or the plaque.
    • The IVUS Solution: Dr. Saha inserts a tiny ultrasound probe into the artery. It spins and sends sound waves (like a submarine sonar).
    • The Vision: It shows the true size of the vessel, the hardness of the plaque, and exactly where the healthy tissue begins.

    2. Prevents “Under-Expansion” (The #1 Killer) IVUS Guided Angioplasty in Kolkata

    The main reason stents fail (restenosis) is that they were not opened fully during the first surgery.

    • The Risk: If a 3.0mm stent is only opened to 2.5mm, it creates turbulence and clots.
    • The IVUS Check: Dr. Saha measures the stent area after deployment. If IVUS shows it is not circular or fully touching the wall, he uses a high-pressure balloon to expand it further until it is perfect.

    3. Choosing the Exact Stent Size

    “Eyeballing” the size on an X-ray is often wrong.

    • The Precision: IVUS measures the vessel diameter to 0.1mm accuracy.
    • The Outcome: Dr. Saha picks a stent that matches your artery 1:1. Not too small (which floats), and not too big (which tears the vessel).

    4. Cost-Effective Precision IVUS Guided Angioplasty in Kolkata

    Patients often ask: “How is it different from OCT?”

    • OCT: Uses Light. Higher resolution (HD), but more expensive and requires more dye.
    • IVUS: Uses Sound. Great resolution (SD), but cheaper and requires less dye.
    • The Verdict: IVUS is the perfect balance of high-tech safety and affordability for most complex cases.

    5. Essential for “Left Main” Disease IVUS Guided Angioplasty in Kolkata

    The “Left Main” artery is the widow-maker. Stenting it is high-risk. International guidelines say IVUS is Mandatory for Left Main stenting. Dr. Saha strictly follows this protocol. He never stents a Left Main artery blindly.

  • OCT Guided Angioplasty in Kolkata: 5 Vital Secrets for Precision

    Introduction OCT Guided Angioplasty in Kolkata

    You want the best for your heart. You’ve heard of Angiography and maybe even IVUS. But have you heard of the technology that allows doctors to see inside your artery with microscopic clarity? OCT Guided Angioplasty in Kolkata

    It is called OCT (Optical Coherence Tomography). While IVUS uses sound waves (like a bat), OCT uses Infrared Light (like a telescope).

    Dr. Avishek Saha, a certified expert in intravascular imaging, explains OCT Guided Angioplasty in Kolkata—the highest-resolution imaging available on the planet to ensure your stent is placed perfectly.

    1. 10x Sharper Than IVUS OCT Guided Angioplasty in Kolkata

    IVUS is great, but OCT is in a league of its own.

    • The Resolution: IVUS has a resolution of about 100 microns. OCT has a resolution of 10 microns.
    • The Visual: Imagine the difference between a fuzzy old TV and a crystal-clear 4K Screen.
    • The Benefit: Dr. Saha can see the individual layers of your artery wall, tiny blood clots, and even the thickness of the plaque cap that caused your heart attack.

    2. Perfect Stent Sizing (Down to the Millimeter) OCT Guided Angioplasty in Kolkata

    Guesswork has no place in heart surgery.

    • The Scan: The OCT probe scans the artery in seconds.
    • The AI: Advanced software automatically measures the exact diameter of the vessel at the landing zone.
    • The Fit: This ensures Dr. Saha chooses a stent that fits you like a custom-made suit—not too loose (which causes clots) and not too tight (which damages the wall).

    3. It Detects “Edge Dissections”

    Sometimes, when a stent is placed, the edge of the artery tears slightly (Dissection).

    • The Danger: On a normal X-ray, this is invisible. If left untreated, it can cause a sudden heart attack later.
    • The OCT Safety: OCT picks up these tiny tears instantly. Dr. Saha can fix them right there on the table, preventing a future emergency.

    4. Checking for “Malapposition”

    A stent must hug the artery wall tightly.

    • The Problem: Sometimes, a stent strut hangs loose in the bloodstream (Malapposition). This is a magnet for blood clots.
    • The Solution: OCT allows Dr. Saha to “fly through” the stent in 3D. He can see if every single strut is touching the wall. If not, he uses a balloon to fix it immediately.

    5. Available Only at Premium Centers OCT Guided Angioplasty in Kolkata

    OCT is expensive, cutting-edge technology. It is not available in every nursing home. Dr. Saha performs OCT-guided procedures at Kolkata’s most advanced cardiac institutes.
