Shockwave Intravascular Lithotripsy – “Shockwave Balloon” to Break Artery Calcium During Angioplasty

This video presents a technical overview of Shockwave Intravascular Lithotripsy (IVL), a catheter-based calcium modification technology used during PCI and peripheral interventions to treat severely calcified arterial lesions. The system is examined from an engineering and interventional cardiology perspective, focusing on the IVL balloon catheter that integrates lithotripsy emitters, a generator/connector console, and standard guidewire-based delivery. The video explains how short acoustic pressure pulses are delivered inside an inflated balloon to create microfractures in intimal and medial calcium, improving vessel compliance and enabling safer, more predictable stent expansion or balloon dilation at relatively low balloon pressures. Key topics include device components, procedural workflow (wire crossing, IVL balloon positioning, pulse delivery cycles, post-dilation, stent deployment when applicable), and the physics of acoustic energy transmission through fluid to target calcified plaque. The presentation also discusses practical considerations such as lesion selection (coronary vs peripheral), imaging guidance with IVUS/OCT where available, compatibility with standard cath lab equipment, and safety concepts such as controlled energy delivery and reduced barotrauma compared with high-pressure dilation alone.
