THE EFFECTIVENESS OF EXCIMER LASER ANGIOPLASTY TO TREAT CORONARY IN-STENT RESTENOSIS WITH PERI-STENT CALCIUM AS ASSESSED BY OPTICAL COHERENCE TOMOGRAPHY

Background: We used optical coherence tomography to evaluate excimer laser coronary angioplasty (ELCA) to treat in-stent restenosis (ISR) due to peri-stent calcium (Ca) related stent underexpansion. Methods: We studied 53 ISR lesions with >90° peri-stent Ca and compared ECLA (n=21) vs no-ELCA (n=

COMPARISON OF OPTICAL COHERENCE TOMOGRAPHY VERSUS INTRAVASCULAR ULTRASOUND DETECTION OF TISSUE PROTRUSION AND ACUTE STENT-VESSEL WALL MALAPPOSITION IN 498 PATIENTS AFTER DRUG-ELUTING STENT IMPLANTATION

Background: Optical coherence tomography (OCT) has higher resolution and improved tissue characterization compared to intravascular ultrasound (IVUS). Methods: We retrospectively analyzed 498 pts (44.1% acute coronary syndrome) who underwent stent implantation with final IVUS and OCT. Tissue

TCT-562 Impact of Serum LDL and Statin Therapy on Coronary Plaque Morphology: An OCT and IVUS Co-registered Study

We sought to investigate the association between serum LDL cholesterol, statin use, plaque vulnerability, and lipid composition using both optical coherence tomography (OCT) and intravascular ultrasound (IVUS). We retrospectively analyzed 805 pts with CAD (38.9% acute coronary syndromes [ACS]) who

TCT-576 Clinical Determinants of Plaque Morphology in Coronary Artery Disease: An OCT and IVUS Co-Registered Study

We sought to investigate clinical determinants of overall disease burden and plaque vulnerability using both optical coherence tomography (OCT) and intravascular ultrasound (IVUS) in a large cohort of patients with coronary artery disease (CAD). We retrospectively analyzed a total of 811 patients

TCT-566 Association Between Lesion Remodeling and Plaque Morphology Assessed By Intravascular Ultrasound and Optical Coherence Tomography

We evaluated the association between intravascular ultrasound (IVUS)-defined remodeling and optical coherence tomography (OCT)-defined plaque morphology. Overall, 277 pts with acute coronary syndromes (ACS) and 421 pts with stable angina underwent IVUS and OCT pre-PCI. IVUS remodeling index (RI)

TCT-587 Can OCT-Detected Healed Plaque Rupture or Erosion Predict Side Branch Occlusion?

Healed asymptomatic plaque rupture/erosion can be detected by optical coherence tomography (OCT). We hypothesized that healed plaque (HP) is relatively soft and easily shifts into a side branch (SB) during bifurcation stenting. We studied 195 pts with 207 bifurcation lesions (SB diameter >1.5 mm)
