      Coronary Artery Occlusion Caused by Intramural Hematoma Due to In-Stent Dissection
      A 54-year-old man developed ST-segment elevation myocardial infarction 1 week after percutaneous coronary intervention of the left anterior descending artery. Optical coherence tomography at the emergent percutaneous coronary intervention revealed an intramural hematoma extending from the in-stent dissection. We highlight that in-stent dissection, although generally considered a benign finding, can extend and cause intramural hematoma, resulting in coronary artery occlusion.

      Utility of Multimodality Intravascular Imaging and the Local Hemodynamic Forces to Predict Atherosclerotic Disease Progression
      Objectives This study sought to examine the utility of multimodality intravascular imaging and of the endothelial shear stress (ESS) distribution to predict atherosclerotic evolution. Background There is robust evidence that intravascular ultrasound (IVUS)-derived plaque characteristics and ESS distribution can predict, with however limited accuracy, atherosclerotic evolution; nevertheless, it is yet unclear whether multimodality imaging and ESS mapping enable more accurate prediction of coronary plaque progression. Methods A total of ...

      Mechanism of Drug-Eluting Absorbable Metal Scaffold Restenosis: A Serial Optical Coherence Tomography Study
      Background: The pathomechanisms underlying restenosis of the bioabsorbable sirolimus-eluting metallic scaffold (Magmaris) remain unknown. Using serial optical coherence tomography, we investigated causes of restenosis, including the contribution of late scaffold recoil versus neointimal hyperplasia. Methods: Patients enrolled in BIOSOLVE-II undergoing serial angiography and optical coherence tomography (post-intervention and follow-up: 6 months and/or 1 year) were analyzed. Patients were divided into 2 groups according to angiographic in-scaffold late lumen loss ...
