Bail-out therapy in ST-segment elevation myocardial infarction due to calcified lesion causing stent underexpansion: Intravascular lithotripsy is in the lead.

ABSTRACT: A 52-year-old male was referred for an acute anterior ST-segment elevation myocardial infarction (STEMI). Coronary angiography revealed an acute left anterior descending artery occlusion. The patient was treated with a drug-eluting stent (DES). Despite long and repeated high-pressure inflations (>20 atm) of non-compliant balloons, OPN NC^Ⓡ high-pressure balloon (SIS Medical AG; Frauenfeld, Switzerland), rotational atherectomy, and cutting balloon, there was a severe hourglass stent underexpansion caused by coronary calcification. Thus, intravascular lithotripsy (IVL) (Shockwave Medical, Fremont, CA, USA) was attempted to re-dilate this calcified lesion. Underexpansion was successfully treated after delivering 70 shockwaves to the narrowest segment. IVL delivers localized pulsatil
