Procedures, performed by the cardiologist you see in clinic

Dr Ramzy performs coronary and structural heart procedures himself, so the doctor who assesses you is the doctor who treats you.

Procedures and tests

Coronary stenting

Measured, not estimated

Before placing a stent, Dr Ramzy measures how much a narrowing affects blood flow and looks inside the artery to size the stent. Step through how it works.

How a coronary stent is placed

Step 1 of 4

  1. A pressure wire confirms the narrowing is reducing blood flow, so a stent is only placed where it helps.

  2. An ultrasound (IVUS) or light-based (OCT) catheter maps the plaque and the artery’s true size.

  3. A balloon carrying the stent is inflated, pressing the stent into the artery wall.

  4. The balloon is removed and imaging confirms the stent is fully expanded and well positioned.
