Evaluation of Treatment Response of Calcified Nodules and Nodular Calcified Lesions Using Mean Density on Coronary Computed Tomography Angiography

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified nodules (CN) and nodular calcifications (NC) present significant challenges during percutaneous coronary intervention (PCI) because of their protruding morphology and high rigidity, which often result in inadequate stent expansion and suboptimal procedural outcomes.

Hospital‐Level Variations in Outcomes and Readmissions Among Patients With STEMI and Cardiogenic Shock Receiving Mechanical Circulatory Support: Insights From a National Cohort

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The utilization of mechanical circulatory support (MCS) in patients presenting with ST‐elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS) has increased substantially in recent years. However, it remains unclear whether the spectrum of MCS devices available and the type of hospital in which patients are ...

Enhanced Method for Localization of Partial Discharges in Oil-Filled Transformers Using Acoustic Emission Signals

International Journal of Prognostics and Health Management
Accurate measurement of partial discharges (PD) in power transformers is crucial for fault identification and effective maintenance planning. Acoustic emission (AE) sensing, less susceptible to external electromagnetic interference, offers non-invasive ...

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...

Interaction of Operator−Patient Sex on Peri‐Procedural Treatments and Major Coronary Outcomes After Percutaneous Coronary Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background There are limited data evaluating the association between operator−patient sex, and outcomes in patients undergoing percutaneous coronary intervention (PCI). Methods We included 138,112 consecutive PCI procedures in patients presenting with acute coronary syndrome (ACS) in England and Wales, 2017−2020.

Interventional Mitral Valve Edge‐to‐Edge Repair in Patients Above 85 Years of Age

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Mitral valve transcatheter‐edge‐to‐edge repair (M‐TEER) is routinely performed in patients with severe mitral regurgitation (MR) at high operative risk, frequently including elderly patients. Patients ≥ 85 years, however, are frequently excluded in clinical studies.

Clinical Outcomes of the Allegra Transcatheter System in Bioprosthetic Aortic Valve Failure: A Multicentre Valve‐in‐Valve Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Introduction The prevalence of bioprosthetic aortic valve failure is increasing due to the broader use of bioprosthetic valves, both surgical and transcatheter, and an ageing population. Registry data indicate a higher risk of coronary obstruction and elevated gradients following valve‐in‐valve transcatheter aortic valve implantation (TAVI ...
