      Predictive value of plaque morphology assessed by frequency-domain optical coherence tomography for impaired microvascular perfusion after elective stent implantation: the intracoronary electrocardiogram study

      Aims This study was undertaken to assess the association between plaque features at culprit lesions assessed by frequency-domain optical coherence tomography (FD-OCT) and impaired microvascular perfusion estimated by intracoronary electrocardiogram (IcECG) after elective percutaneous coronary intervention (PCI). Furthermore, we investigated whether IcECG could predict future cardiac events. Methods and results This study consisted of 84 patients who underwent both FD-OCT and IcECG during PCI. Patients were classified into two groups based on ST-segment elevation (ST-E) on IcECG after the procedure; ST-E (−) group ( n  = 53) and ST-E (+) group ( n  = 31). Minimum fibrous cap thickness was significantly thinner in the ST-E (+) group ...

    2. Slow-Flow Phenomenon After Paclitaxel-Coated Balloon Angioplasty: Findings From Optical Coherence Tomography and Coronary Angioscopy

      Slow-Flow Phenomenon After Paclitaxel-Coated Balloon Angioplasty: Findings From Optical Coherence Tomography and Coronary Angioscopy

      In case 1, a 60-year-old man underwent a 4.0-mm × 12-mm bare-metal stent (BMS) implantation in the proximal left anterior descending coronary artery. Six months after BMS implantation, a coronary angiogram demonstrated in-stent restenosis (ISR) at the proximal portion of the stent (Figure 1 ). Frequency-domain optical coherence tomography (FD-OCT) revealed homogeneous neointima (Figure 1 ) and coronary angioscopy (CAS) revealed white neointimal coverage at the ISR site (Figure 1 ). The lesion was dilated using a 3.5 × 13-mm conventional balloon catheter at 16 atm. After balloon angioplasty, Thrombolysis In Myocardial Infarction (TIMI) flow grade 3 was achieved, and intracoronary electrocardiography did ...
