After unsuccessful percutaneous coronary interventions (PCI) with high-pressure balloons (40 atm) and rotational atherectomy (1.5 mm burr), a 70-year-old woman was re-admitted for lithoplasty-assisted PCI. Lithoplasty balloons (Shockwave Medical, Freemont, California) were developed based on the principles of kidney stone treatment. With an array of emitters they generate pulsatile, circumferential sonic pressure waves to selectively disrupt intimal and medial calcifications, usually resulting in calcium tears and focal dissections [ 1, 2].
In this patient with Canadian Cardiovascular Society Class II angina, the 6 Fr compatible device effectively modified the extremely resistant lesion (Fig.  1a). Optical coherence tomography (OCT) showed typical calcium tears and a large dissection (Fig.  1b; [ 24]). To cover the lesion, a drug-eluting stent (4.5 mm) was implanted and post-dilated with a non-compliant balloon. Proper stent expansion and apposition were confirmed with OCT.
In conclusion, lithoplasty may become an essential and safe plaque modification tool, especially in coronary arteries with large inner diameters and subintimal calcifications [ 2].
