Background: Studies suggest percutaneous coronary intervention (PCI) guided by intracoronary imaging (ICI) results in larger balloon/stent diameters and longer stents. Whether this occurs in real-world PCI is poorly understood.
Methods: De novo PCIs performed at 48 nonfederal Michigan hospitals between July 2019 and June 2022 were evaluated with regression modeling to evaluate associations between ICI-guided PCI and balloon/stent dimensions.

Innovation has been the cornerstone of progress in the field of percutaneous coronary intervention (PCI) since its inception. Refinements in procedural technique and interventional tools have improved patient outcomes and overall safety. Despite this progress, however, the health risks posed to operators and staff remain undeniably high.

The use of ionizing radiation during cardiac catheterization procedures poses risks to patients and medical staff, both directly and indirectly through orthopedic injuries caused by lead aprons. In this review, we summarize recent advances in radiation protection in the cardiac catheterization laboratory and discuss the effectiveness of traditional and novel radiation protection strategies and equipment.

Telesurgery has the potential to overcome geographical barriers in surgical care, encouraging its deployment in areas with sparse surgical expertise. Despite successful in-human experiments and substantial technological progress, the adoption of telesurgery remains slow. In this Review, we analyze the reasons for this slow adoption.

Objectives: This preclinical study explored the feasibility of telerobotic ICA between separate continents.
Methods: Using a novel robotic system, attempts were made to navigate a magnetic guidewire and diagnostic catheter from the aortic arch into a target coronary artery ostium in a fluid-filled cardiac model.
Background: Interventional echocardiography (IE) plays a critical role in guiding structural heart interventions. IE specialists face challenges including high radiation exposure and unfavorable ergonomics. To address these issues, a novel remote-control robotic (RCR) system for transesophageal echocardiography (TEE) control has been developed.

Background: Little is known about institutional radiation doses during transcatheter valve interventions.
Objectives: The authors sought to evaluate institutional variability in radiation doses during transcatheter valve interventions.
Methods: Using a large statewide registry, transcatheter edge-to-edge mitral valve repair, transcatheter mitral valve replacement, and transcatheter aortic valve replacement procedures between January 1, 2020, and December 31, 2022, with an air kerma (AK) recorded were analyzed.
Aims: Healed plaque (HP) is associated with rapid plaque growth and luminal narrowing. Thin-cap fibroatheroma (TCFA) is recognized as a precursor lesion to plaque rupture. The aim of the present study was to compare the lipid size among optical coherence tomography (OCT)-derived HP, TCFA, and thick-cap fibroatheroma (ThCFA) using near-infrared spectroscopy-intravascular ultrasound (NIRS-IVUS).

Background: A novel radiation protection system has recently been shown to shield the primary operator from scatter radiation, but whether it shields other members of the catheterization laboratory team remains unknown.
Methods: Radiation exposure data were collected prospectively in 50 coronary angiography cases, in which 25 were completed using standard radiation protection and 25 with a novel system consisting of a series of rigid shields and flexible radiation-resistant drapes. Radiation doses, measured with real-time dosimeters, were compared between the 2 groups.

Background: A multidisciplinary heart team (HT) approach to patients with complex coronary artery disease has a class IB recommendation, yet there are limited data on adherence to HT treatment recommendations and long-term clinical follow-up. The objective of this study was to assess adherence rates to HT recommendations and assess long-term mortality rates among patients with complex CAD.
Methods And Results: Six hundred eighty-four sequential HT cases for complex coronary artery disease from January 2015 to May 2017 were reviewed.

Background: With an aging population and an increase in the comorbidity burden of patients undergoing percutaneous coronary intervention (PCI), the management of coronary calcification for optimal PCI is critical in contemporary practice.
Objectives: This study sought to examine the trends and outcomes of coronary intravascular lithotripsy (IVL), rotational/orbital atherectomy, or both among patients who underwent PCI in Michigan.
Methods: We included all PCIs between January 1, 2021, and June 30, 2022, performed at 48 Michigan hospitals.

Background: Preprocedural anxiety may have detrimental effects both cognitively and physiologically.
Objectives: The objective of this study was to determine the association between state (situational) and trait (persistent in everyday life) anxiety and differences between the adult congenital heart disease (ACHD) and acquired heart disease populations.
Methods: The State-Trait Anxiety Inventory and financial stress scale were administered to adults with acquired and CHD at 4 tertiary referral centers in the United States prior to cardiac catheterization.

Background: Improved radiation safety practices are needed across hospitals performing percutaneous coronary intervention (PCI). This study was performed to assess the temporal trend in PCI radiation doses concurrent with the conduct of a statewide radiation safety initiative.
Methods: A statewide initiative to reduce PCI radiation doses was conducted in Michigan between 2017 and 2021 and included focused radiation safety education, reporting of institutional radiation doses, and implementation of radiation performance metrics for hospitals.
Acute myocardial infarction (AMI) can rarely arise from non-lipid-rich coronary plaques. This study sought to compare the clinical outcomes after percutaneous coronary intervention (PCI) between AMI showing maximum lipid-core burden index in 4 mm (maxLCBI) < 400 and ≥ 400 in the infarct-related lesions assessed by near-infrared spectroscopy-intravascular ultrasound (NIRS-IVUS). We investigated 426 AMI patients who underwent NIRS-IVUS in the infarct-related lesions before PCI.
View Article and Find Full Text PDFIntracoronary near-infrared spectroscopy (NIRS) has been extensively validated against the gold standard of histopathology to identify lipid-rich plaque. NIRS is currently in clinical use as a combined multimodality imaging catheter with intravascular ultrasonography. When used before PCI, NIRS has clinical utility in determining the mechanism underlying acute coronary syndromes and can be used to guide stent length selection and identify the risk of periprocedural myocardial infarction.

Background: Intracoronary imaging (ICI) during percutaneous coronary intervention (PCI) improves outcomes, yet hospital- and physician-level variabilities in ICI and its impact on ICI use in contemporary PCI remain unknown. This study was performed to evaluate hospital- and physician-level use of ICI to optimize PCI.
Methods: Using data from a large statewide registry, patients undergoing PCI between July 2019 and March 2021 were studied.
Background: Cardiologists performing coronary angiography (CA) and percutaneous coronary intervention (PCI) are at risk of health problems related to chronic occupational radiation exposure. Unlike during CA and PCI, physician radiation exposure during right heart catheterization (RHC) and endomyocardial biopsy (EMB) has not been adequately studied. The objective of this study was to assess physicians' radiation doses during RHC with and without EMB and compare them to those of CA and PCI.

Importance: Transesophageal echocardiography during percutaneous left atrial appendage closure (LAAO) and transcatheter edge-to-edge mitral valve repair (TEER) require an interventional echocardiographer to stand near the radiation source and patient, the primary source of scatter radiation. Despite previous work demonstrating high radiation exposure for interventional cardiologists performing percutaneous coronary and structural heart interventions, similar data for interventional echocardiographers are lacking.
Objective: To assess whether interventional echocardiographers are exposed to greater radiation doses than interventional cardiologists and sonographers during structural heart procedures.
