Dilatation and percutaneous coronary intervention in the presence of calcified lesions is particularly demanding and presents a challenge in the daily work of an interventional cardiologist. Coronary calcification is a marker of the progress of the atherosclerotic process. The existence of calcifying lesions predicts a poorer clinical outcome and is associated with increased mortality and the occurrence of postprocedural major adverse cardiovascular events (MACEs). A male patient who was 61 years old was admitted as a result of ST-elevation myocardial infarction (STEMI) complicated by cardiac arrest caused by in-stent thrombosis of a previously suboptimally expanded stent. The lesion did not respond to a dilation attempt with a noncompliant (NC) balloon; however, an optimal result was obtained with inflation from a super-high-pressure NC balloon (OPN NC) for ultra-high-pressure inflations. Resistant, calcified lesions require a careful and comprehensive approach. The OPN NC balloon has a place in the treatment of this type of lesion. An optimized therapeutic modality after the procedure is imperative to prevent a MACE.
