A 54-year-old male was found to have neuroendocrine carcinoma with hepatic metastasis. Two-dimensional (2D) transthoracic echocardiography (TTE) demonstrated dilated right ventricle and right atrium, and severe tricuspid and pulmonary regurgitation. Three-dimensional (3D) TTE en-face views showed thickened, retracted, and fixed tricuspid valve and pulmonic valve which remained widely open throughout the cardiac cycle. 3D TTE, particularly en-face views, demonstrates incremental value over 2D TTE by providing precise valvular anatomic details comparable to surgical findings. 3D TTE also offers a unique opportunity to assess all four valves simultaneously with en-face views to delineate their relationships with surrounding structures.

Background: Balloon-assisted bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BA-BASILICA) enables valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) in patients at risk of coronary artery obstruction. However, its efficacy in patients with severely calcified leaflets remains unclear.
Case Summary: We report a 78-year-old woman with a deteriorated 21 mm Carpentier-Edwards PERIMOUNT Magna valve.
The Coraco-Gleno-Scapular Line: A Simple Novel Tool for Assessing Glenoid Bone Defects.
J ISAKOS

Vale Hospital, Madurai. Electronic address:
Background: Treatment decisions for shoulder instability often necessitate surgical intervention, with glenoid bone loss being a key factor. Currently, various techniques exist to identify glenoid bone loss, each with its own advantages and disadvantages. This study introduces the Coraco-Gleno-Scapular (CGS) line as a tool for assessing critical glenoid bone defects.

Department of Musculoskeletal Radiology, The Royal Orthopaedic Hospital, Bristol Road South, Northfield, Birmingham, UK.
Background: Evaluation of glenoid bone loss following recurrent anterior shoulder dislocations is normally performed using cross sectional imaging.
Objectives: To assess how anteroposterior (AP) and Bernageau view radiographs compare to computed tomography (CT), magnetic resonance imaging (MRI) and arthroscopy for evaluating glenoid bone loss in patients with recurrent anterior shoulder dislocation.
Materials And Methods: A prospective observational study was performed on 32 patients over two years at a tertiary orthopedic center.
Optical coherence tomography angiography in neovascular age-related macular degeneration: comprehensive review of advancements and future perspective.

Optical coherence tomography angiography (OCTA) holds promise in enhancing the care of various retinal vascular diseases, including neovascular age-related macular degeneration (nAMD). Given nAMD's vascular nature and the distinct vasculature of macular neovascularization (MNV), detailed analysis is expected to gain significance. Research in artificial intelligence (AI) indicates that en-face OCTA views may offer superior predictive capabilities than spectral domain optical coherence tomography (SD-OCT) images, highlighting the necessity to identify key vascular parameters.

Purpose: Swept-source OCT angiography (SS-OCTA) scans of eyes with age-related macular degeneration (AMD) were used to replace color, autofluorescence, infrared reflectance, and dye-based fundus angiographic imaging for the diagnosis and staging of AMD. Through the use of different algorithms with the SS-OCTA scans, both structural and angiographic information can be viewed and assessed using both cross sectional and en face imaging strategies.
