      Intravascular Ultrasound–Derived Calcium Score to Predict Stent Expansion in Severely Calcified Lesions | Circulation: Cardiovascular Interventions

      Background: Coronary calcification inhibits stent expansion. We sought to establish an intravascular ultrasound–derived calcium score to predict stent underexpansion. Methods: This is a retrospective observational study including de novo lesions that underwent intravascular ultrasound–guided stenting and had maximum superficial calcium angle >270°. Lesions with angiographic calcium not treated with atherectomy or scoring/cutting balloon before stent implantation were randomly divided into derivation and validation cohorts. The end point was stent expansion (minimum stent area/average of reference lumen area) at the maximum calcium site, and stent expansion <70% was considered underexpansion. Results: The morphological characteristics associated with stent ...

      In-Stent Restenosis Lesion Morphology Related to Repeat Stenting Underexpansion as Evaluated by Optical Coherence Tomography

      Aims: To use optical coherence tomography (OCT) to predict newly implanted stent expansion for treatment of in-stent restenosis (ISR). Methods and results: With OCT-guidance, 143 ISR lesions were treated with a new stent. Stent underexpansion was defined as minimum stent area (MSA) <4.5mm 2 and MSA/average of reference lumen area <70%. New stent underexpansion was found in 33 lesions (23%), had a smaller old stent MSA (4.13 [3.32-4.62] versus 5.18 [4.01-6.38] mm 2 , p=0.001), and had a higher prevalence of multiple old stent layers (51.5% versus 10.9%, p ...

    3. Utility of intracoronary imaging in the cardiac catheterization laboratory: comprehensive evaluation with intravascular ultrasound and optical coherence tomography

      Utility of intracoronary imaging in the cardiac catheterization laboratory: comprehensive evaluation with intravascular ultrasound and optical coherence tomography

      Background Intracoronary imaging is an important tool for guiding decision making in the cardiac catheterization laboratory. Sources of data We have reviewed the latest available evidence in the field to highlight the various potential benefits of intravascular imaging. Areas of agreement Coronary angiography has been considered the gold standard test to appropriately diagnose and manage patients with coronary artery disease, but it has the inherent limitation of being a 2-dimensional x-ray lumenogram of a complex 3-dimensional vascular structure. Areas of controversy There is well-established inter- and intra-observer variability in reporting coronary angiograms leading to potential variability in various management strategies ...

    4. A Case of On-line Software-based Co-registration of Optical Coherence Tomography and Angiography Guided Percutaneous Coronary Intervention for a Patient With Angina Pectoris

      A Case of On-line Software-based Co-registration of Optical Coherence Tomography and Angiography Guided Percutaneous Coronary Intervention for a Patient With Angina Pectoris

      Recently developed imaging modalities provide precise and accurate evaluation of lesions within the coronary arteries. Among them, optical coherence tomography (OCT) provides higher resolution cross-sectional imaging than intravascular ultrasound [1]. Recently, software-based on-line co-registration of OCT and angiography has become available as a new tool in percutaneous coronary intervention. Here, we describe a case where this new modality was critical for successful percutaneous coronary intervention.
