Ep. 25 IVL & Atherectomy: Techniques for Complex PCI with Dr. Yousif Ahmad
How do imaging, intravascular lithotripsy, and equipment selection come together to effectively target coronary calcium? In this episode of BackTable, interventional cardiologists Dr. Robert Riley (Overlake Medical Center in Bellevue, Washington) and Dr. Yousif Ahmad (UCSF) trade techniques and discuss various aspects of calcium modification in complex percutaneous coronary intervention (PCI).

SYNPOSIS
The discussion begins with an overview of intravascular lithotripsy (IVL), including its mechanism of action, ideal lesion characteristics, and performance across varying calcium morphologies. The conversation then expands to comparative decision-making among atherectomy, specialty balloons, and IVL, emphasizing how intravascular imaging informs procedural planning and real-time optimization. Key clinical data are reviewed, including the Disrupt CAD I-IV series as well as findings from the Short-Cut and VICTORY trials. The episode concludes with a forward-looking discussion on emerging technologies and the ongoing challenge of treating calcified nodules, one of the most demanding substrates in coronary intervention.
