Causes of intracerebral hemorrhage are mostly attributed to vascular anomalies or hypertension. It causes significant morbidity and mortality worldwide. This illustrative case report presents an interesting computed tomography image of hyperacute basal ganglia hemorrhage with intraventricular extension artistically casting the ventricular system. The intraventricular hemorrhage was moderate upon presentation; the blood had delineated the anatomic details of the ventricular system. It closely resembles a Crax rubra's head in the sagittal view. We believe that this radiographic finding is not seen frequently, especially early in the course of the condition. However, it could serve as an intriguing and reproducible sign of the radiographic anatomy of the ventricular system.

Purpose: This literature review aims to synthesise current research on the application of artificial intelligence (AI) for the segmentation of brain neuroanatomical structures in magnetic resonance imaging (MRI).
Methods: A literature search was conducted using the databases Embase, Medline, Scopus, and Web of Science, and captured articles were assessed for inclusion in the review. Data extraction was performed for the summary of the AI model used, and key findings of each article, advantages and disadvantages were identified.

Cardiovascular disease (CVD) is the leading cause of death in the United States. Damage in the cardiovascular system can be due to environmental exposure, trauma, drug toxicity, or numerous other factors. As a result, cardiac tissue and vasculature undergo structural changes and display diminished function.

The next step in the evolution of static 3-dimensionally (3D) printed models may be the creation of "smart" models, where subcomponents can be seamlessly interacted with through a feedback mechanism, with potential applications in trainee education and patient counseling. Considering the complexity of the ventricular and cisternal systems, they were chosen for segmentation, using Materialize InPrint with outward hollowing using 2.5-mm wall thickness.

Introduction: The role of the sympathetic nervous system in the initiation and continuation of ventricular tachyarrhythmias (VTA) is well established. However, whether CSD reduces implantable cardioverter-defibrillator (ICD) shocks and recurrent VTA is still uncertain.
Methods: A comprehensive literature search was performed at Medline and Embase until March 2023.

Aims: This study evaluates whether multi-chamber myocardial deformation analysis using speckle tracking echocardiography (STE) can enhance validated current staging systems and improve risk stratification for patients with moderate-to-severe aortic stenosis (AS).
Methods And Results: We reanalyzed 2D, Doppler, and STE data obtained from two cohorts: derivation (654 patients, median age: 82 years; 51% men) and validation (237 patients, median age: 77 years; 55% men) with at least moderate AS (aortic valve area<1.5 cm2).
