Key result
Shockwave intravascular lithotripsy successfully treats calcified coronary lesions in 3 STEMI cases including bail-out use.
Why the study?
The use of Shockwave intravascular lithotripsy for coronary calcium modification in STEMI patients undergoing PCI had not been previously reported.
Case Report (n=3)
This case series provides the first reported experience of using intravascular lithotripsy for calcium modification during percutaneous coronary intervention in the setting of STEMI.
May support intravascular lithotripsy in select calcified STEMI cases; leaves open safety and efficacy pending prospective trials.
We present the first cases of Shockwave intravascular lithotripsy (S-IVL; Shockwave Medical), a novel coronary calcium modification device, being used in patients undergoing percutaneous coronary intervention for ST-elevation myocardial infarction (STEMI). The 3 presented cases include an upfront use of S-IVL in a right coronary artery, an in-stent restenosis, and a community cardiac arrest/STEMI equivalent where S-IVL was used as a bail-out technique to facilitate stent delivery in a tortuous calcified vessel.

Wong et al. (2019) conducted a case report in ST-elevation myocardial infarction (STEMI) with calcified coronary lesions (n=3). Shockwave intravascular lithotripsy (S-IVL) was evaluated. Shockwave intravascular lithotripsy was successfully used in 3 cases of STEMI with calcified coronary lesions, including upfront use, in-stent restenosis, and as a bail-out technique.
