      Optical coherence tomography-based machine learning for predicting fractional flow reserve in intermediate coronary stenosis: a feasibility study
      Machine learning approaches using intravascular optical coherence tomography (OCT) to predict fractional flow reserve (FFR) have not been investigated. Both OCT and FFR data were obtained for left anterior descending artery lesions in 125 patients. Training and testing groups were partitioned in the ratio of 5:1. The OCT-based machine learning-FFR was derived for the testing group and compared with wire-based FFR in terms of ischemia diagnosis (FFR 0.8 ...

      Neointima characteristics as a prognostic marker for drug-coated balloon angioplasty in patients with in-stent restenosis: an optical coherence tomography study
      Background Research has shown that the prognosis of in-stent restenosis (ISR) lesions after drug-coated balloon (DCB) angioplasty can differ in relation to in-stent neointimal characteristics. However, changes in neointima characteristics after DCB have not been studied. This study sought to investigate changes in neointima characteristics after DCB for ISR. Methods From the Yonsei Optical Coherence Tomography (OCT) registry, data on DCBs performed in patients with ISR were collected. Neointima characteristics ...

      Silent plaque rupture in the left main stem assessed by optical coherence tomography
      A 59-year-old man underwent primary percutaneous coronary intervention (PCI) for thrombotic total occlusion of his distal right coronary artery. Bystander disease was limited to an ambiguous lesion in the distal left main stem (LMS) with an intraluminal filling defect suggestive of a ruptured plaque. A staged inpatient assessment of the LMS was undertaken utilizing invasive physiologic and intravascular imaging assessments as distal flow in the left coronary system was preserved ...

      Optical Coherence Tomography for Coronary Bioresorbable Vascular Scaffold Implantation: A Randomized Controlled Trial
      Background: We investigated whether optical coherence tomography (OCT) guidance would reduce nonoptimal bioresorbable vascular scaffold (BVS) deployment. Methods: This was a randomized controlled trial. Patients who required percutaneous coronary intervention for ischemic heart disease were recruited from 2 centers in Korea. The enrolled patients were randomly assigned to receive either OCT-guided BVS (Absorb; Abbott Vascular) implantation or angiography-guided BVS implantation using an optimized technique. The primary outcome was nonoptimal deployment ...

      Successful Culotte Stenting for Unprotected Left Main Trifurcation Disease: Insights from Optical Coherence Tomography
      A 41-year-old man presenting with new-onset effort angina was referred to our clinic. Angiography revealed a left main trifurcation lesion including significant stenosis in the unprotected left main coronary artery (ULMCA), ostial left anterior descending artery (LAD), ostial left circumflex artery (LCX) with grade 3 collateral flow from the right coronary artery, and diffuse ramus intermedius artery (RI) ( Supplementary Video 1 ).

      Impact of late stent malapposition after drug-eluting stent implantation on long-term clinical outcomes
      Background and aims The impact of late drug-eluting stent (DES) malapposition detected by optical coherence tomography (OCT) on long-term clinical outcomes has not been clearly established. We evaluated long-term clinical outcomes of late stent malapposition (LSM) detected by OCT in a qualified study population. Methods A total of 428 patients were selected from previous randomized OCT studies that evaluated the degree of strut coverage of different DESs at a 312-month ...

      Severe acute stent malapposition follow-up: 3-month and 12-month serial quantitative analyses by optical coherence tomography
      Background Optical coherence tomography (OCT) was used to assess serial changes in severe acute stent malapposition (ASM) after drug-eluting stent (DES) implantation. Methods The maximal depth and axial lengths of ASM after DES implantation were serially quantified at percutaneous coronary intervention (PCI), and at 3 and 12-month follow-up, for 100 lesions in 96 patients. Severe ASM was defined as a maximal malapposed depth 400 m or maximal malapposed axial length ...
