Coronary IVL has changed the way operators approach calcified coronary disease, but the mechanism is often underappreciated because the device is so simple to use.

In this MurmurMD discussion, Dr. Chris Brown and Dr. Yousif Ahmad walks through a complex calcified coronary case and then breaks down the mechanism of action behind coronary intravascular lithotripsy.

The conversation focuses on Aero: improved deliverability, rewrap, and multivessel treatment in heavily calcified anatomy.

Key topics include:

• Severe calcified coronary disease in a high-risk patient

• Using IVL with minimal lesion preparation

• Deliverability through tortuous, calcified anatomy

• Re-advancing a used IVL balloon after treatment

• Why rewrap performance matters

• Treating multivessel calcified disease more efficiently

• Practical cautions around shorter pause times

• How IVL fractures calcium while limiting vessel injury

• Circumferential 360-degree energy delivery

• Deep calcium penetration and broader energy distribution

• Why coronary IVL has become a major calcium-modification tool

This is a practical discussion for operators who want to understand not just that IVL works, but why it works, and how device iteration may change day-to-day calcium strategy.
