(A) Comparison of the number of high-intensity transient signals (HITS) and their liberation timing throughout the subsequent percutaneous coronary intervention (PCI) procedures: first balloon angioplasty (BA), second BA, stenting, and post-dilation. (B) Correlation between the number of HITS after first BA and that after stenting.
