      COMPARISON OF POST STENT OPTICAL COHERENCE TOMOGRAPHY FINDINGS AMONG THREE SUBTYPES OF CALCIFIED CULPRIT PLAQUES IN PATIENTS WITH ACUTE CORONARY SYNDROME
      Background Recently, three subtypes of calcified plaques at the culprit lesion were reported in patients with acute coronary syndrome (ACS): eruptive calcified nodule, superficial calcific sheet, and calcified protrusion. Methods A total of 157 patients with ACS and calcified plaque at the culprit lesion were selected from our database. Optical coherence tomography (OCT) findings at index procedure and after stent implantation were compared among the three subgroups. Results In the ...

      Comprehensive In Vivo Coronary Plaque Mapping: A 3-Vessel Optical Coherence Tomography Study
      Background Previous pathology studies demonstrated that thin-cap fibroatheroma (TCFA) is localized in specific segments of the epicardial coronary arteries. A detailed description of in vivo coronary plaques of various phenotypes has not been reported. Objectives We performed a comprehensive analysis on the distribution of coronary plaques with different phenotypes from our 3-vessel optical coherence tomography (OCT) database.

    5. Characteristics of non-culprit plaques in acute coronary syndrome patients with layered culprit plaque

      Characteristics of non-culprit plaques in acute coronary syndrome patients with layered culprit plaque
      Aims Layered plaques represent signs of previous plaque destabilization. A recent study showed that acute coronary syndrome (ACS) patients with layered culprit plaque have more vulnerability at the culprit lesion and systemic inflammation. We aimed to compare the characteristics of non-culprit plaques between patients with or without layered plaque at the culprit lesion. We also evaluated the characteristics of layered non-culprit plaques, irrespective of culprit plaque phenotype. Methods and results ...

    6. Usefulness of longitudinal reconstructed optical coherence tomography images for predicting the need for the reverse wire technique during coronary bifurcation interventions

      Usefulness of longitudinal reconstructed optical coherence tomography images for predicting the need for the reverse wire technique during coronary bifurcation interventions
      Objectives The aim is to investigate the usefulness of longitudinal reconstructed optical coherence tomography (OCT) images in selecting the reverse wire (RW) technique for inserting a guidewire into a side branch (SB). Background It is sometimes necessary to protect the SB with a guidewire to prevent SB complications in PCI for bifurcation lesions. The RW is a novel method for guidewire insertion into an extremely angulated SB when the standard ...

    7. Plaque modification of severely calcified coronary lesions by scoring balloon angioplasty using Lacrosse non-slip element: insights from an optical coherence tomography evaluation

      Plaque modification of severely calcified coronary lesions by scoring balloon angioplasty using Lacrosse non-slip element: insights from an optical coherence tomography evaluation
      Percutaneous coronary intervention (PCI) for heavily calcified lesions is challenging because these lesions are resistant to balloon dilatation and stenting. Lacrosse non-slip element (NSE) may have the potential to dilate heavily calcified lesions. We aimed to investigate predictors of successful lesion modification using Lacrosse NSE angioplasty via optical coherence tomography (OCT)-guided PCI. We investigated 32 patients with severe target lesion calcification treated with OCT-guided PCI. Successful lesion modification was ...

    8. Clinical Predictors for Lack of Favorable Vascular Response to Statin Therapy in Patients With Coronary Artery Disease: A Serial Optical Coherence Tomography Study

      Clinical Predictors for Lack of Favorable Vascular Response to Statin Therapy in Patients With Coronary Artery Disease: A Serial Optical Coherence Tomography Study
      Background Previous studies have demonstrated that statin therapy improves cardiac outcomes, probably by stabilizing thin‐cap fibroatheroma in patients with coronary artery disease. However, major adverse cardiac events still occur in some patients, despite statin therapy. The aim of this study is to identify clinical predictors for the lack of a favorable vascular response to statin therapy in patients with coronary artery disease. Methods and Results A total of 140 ...

    9. SYNTAX Score, and Pre- and Post-Stent Optical Coherence Tomography Findings in the Left Anterior Descending Coronary Artery in Patients with Stable Angina Pectoris

      SYNTAX Score, and Pre- and Post-Stent Optical Coherence Tomography Findings in the Left Anterior Descending Coronary Artery in Patients with Stable Angina Pectoris
      SYNTAX score (SS) has been reported to be an independent predictor of future cardiac events including target lesion revascularization (TLR). The aim of this study was to assess the relationship between SS and plaque characteristics and post-stent vascular response using optical coherence tomography (OCT) in coronary artery tree and left anterior descending artery (LAD) in patients with stable angina. A total of 179 lesions among 165 patients, including 100 lesions ...

    11. Management and Outcome of Patients With Acute Coronary Syndrome Caused by Plaque Rupture Versus Plaque Erosion: An Intravascular Optical Coherence Tomography Study

      Management and Outcome of Patients With Acute Coronary Syndrome Caused by Plaque Rupture Versus Plaque Erosion: An Intravascular Optical Coherence Tomography Study
      Background Plaque rupture and erosion are the 2 most common mechanisms for acute coronary syndromes. However, the outcome of these 2 distinct pathologies in patients with acute coronary syndromes has never been studied. Methods and Results We retrospectively studied 141 patients with acute coronary syndromes who underwent optical coherence tomography ( OCT ) imaging of the culprit lesion prior to stenting from the Massachusetts General Hospital OCT Registry. Management (stent versus no ...

    12. Is age an important factor for vascular response to statin therapy? A serial optical coherence tomography and intravascular ultrasound study

      Is age an important factor for vascular response to statin therapy? A serial optical coherence tomography and intravascular ultrasound study
      Objective: Age-related structural and functional changes in vessel wall may affect the time course of vascular response to statin therapy. In this study, we sought to compare the response of lipid-rich plaque to statin therapy in elderly versus younger patients using optical coherence tomography and intravascular ultrasound. Patients and methods: Sixty-nine patients who underwent serial optical coherence tomography and intravascular ultrasound at the time point of baseline, 6, and 12 ...

    13. Impact of branching angle on neointimal coverage of drug-eluting stents implanted in bifurcation lesions

      Impact of branching angle on neointimal coverage of drug-eluting stents implanted in bifurcation lesions
      Objectives: To investigate the impact of branching angle (BA) on neointimal coverage of drug-eluting stents (DESs) in bifurcation lesions. Background: Previous experimental studies indicated that BA influences the local flow turbulence and wall shear stress, which are associated with neointimal coverage of DESs. Methods: Fifty-five bifurcation lesions in 47 patients were evaluated by serial optical coherence tomography (OCT) before DES implantation and at follow-up. Neointimal coverage was assessed in cross-sectional ...

      Prevalence and Predictors of Multiple Coronary Plaque Ruptures In Vivo 3-Vessel Optical Coherence Tomography Imaging Study
      Objective Plaque rupture may be the local expression of a widespread coronary instability. This study aimed to investigate: (1) the prevalence and characteristics of nonculprit plaque rupture; (2) the pancoronary atherosclerotic phenotype in patients with and without nonculprit plaque rupture; and (3) the prevalence and predictors of multiple plaque ruptures. Approach and Results Six hundred and seventy-five nonculprit plaques from 261 patients (34 acute myocardial infarction, 73 unstable angina pectoris ...
