Aero Deliverability, Calcium Fracture, and Real-World Cases

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 toolThis 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.🔔 Subscribe for more insights from interventional experts and real-world program builders.📱 Download the app: https://apps.apple.com/app/apple-store/id1586692687📺 Follow us on YouTube: https://www.youtube.com/channel/UCfrLYhAhliQ2ZvXinkDCZvAChapters: 00:00 – Introduction: coronary IVL case and mechanism discussion00:17 – High-risk calcified coronary case presentation01:47 – Minimal lesion prep and Aero IVL deliverability02:34 – Moving, re-advancing, and reusing the IVL balloon04:41 – Why rewrap performance changes workflow06:04 – Final treatment strategy and angiographic result07:06 – When IVL may replace default atherectomy08:33 – Aero design changes: tip, coating, balloon material, and rewrap09:08 – Practical caution: shorter pauses and ischemic time10:45 – How IVL changes multivessel calcium treatment11:32 – Mechanism of action: pressure waves and calcium fracture12:32 – Consistent energy delivery and 120 pulses13:31 – Circumferential 360-degree energy delivery14:06 – Deep calcium penetration and broader treatment effect15:13 – Why IVL is simple to use but complex underneath16:01 – Closing thoughts#CoronaryIVL #IntravascularLithotripsy #Aero#CoronaryCalcium #CalcifiedLesions#CalciumModification #ComplexCoronary#InterventionalCardiology #MurmurMD
