Regional myocardial perfusions obtained by myocardial contrast echocardiography were compared with wall motion abnormalities evaluated by two-dimensional echocardiography in 26 patients with old myocardial infarction (12 with a QS pattern and 14 with a non-QS pattern on electrocardiograms). Myocardial contrast echocardiography was performed by the intracoronary injection of 2 ml of hand-agitated Urografin-76, and short-axis views of the left ventricle were recorded on VTR. Regional myocardial perfusion was categorized using a three-point scale based on the gray levels, and was compared with wall motion abnormalities of the corresponding region as assessed by two-dimensional echocardiography.

Implications of a new clinical classification of acute myocardial infarction.
Eur Heart J Acute Cardiovasc Care

BHF/University Centre for Cardiovascular Science, University of Edinburgh, Edinburgh, UK.
Aim: The diagnostic criteria for type 2 myocardial infarction identify a heterogenous group of patients with variable outcomes and no clear treatment implications. We aimed to determine the implications of a new clinical classification for myocardial infarction with more objective diagnostic criteria using cardiac imaging.
Methods: In a prospective cohort study, patients with type 2 myocardial infarction underwent coronary angiography and cardiac magnetic resonance imaging or echocardiography.
Myocarditis as a Possible Underlying Cause for Mid-Ventricular Takotsubo Cardiomyopathy: A Case Report.
Cureus

Medicine, Florida International University, Herbert Wertheim College of Medicine, Miami, USA.
Our case report characterizes a rare presentation of mid-ventricular Takotsubo cardiomyopathy (TTC) in a patient with suspected myocarditis as an underlying cause. Mid-ventricular TTC is a rare variant of TTC presenting with overlapping symptoms and physical exam findings of acute coronary syndrome, which often leads to misdiagnosis as myocardial infarction. Our case is of a 77-year-old female patient with a history of hyperlipidemia, right breast ductal carcinoma in situ, and diverticular disease who presented to the emergency department for evaluation of chest pain radiating to the jaw with associated nausea and vomiting.

Department of Orthopaedic Surgery, Washington University School of Medicine, Saint Louis, MO. Electronic address:
Purpose: Isolated coronal shear fractures of the distal humerus in adolescents are rare injuries with unique surgical challenges. Respect for the posterior blood supply, open physes, and need for direct visualization to achieve anatomic reduction are critical considerations in surgical fixation. This study presents a case series and a surgical approach used in treating these patients.

The implementation of collective motion, traditionally, disregard the limited sensing capabilities of an individual, to instead assuming an omniscient perception of the environment. This study implements a visual flocking model in a ``robot-in-the-loop'' approach to reproduce these behaviors with a flock composed of 10 independent spherical robots. The model achieves robotic collective motion by only using panoramic visual information of each robot, such as retinal position, optical size and optic flow of the neighboring robots.

Aims: Aortic wall stiffening in ascending thoracic aortic aneurysm (aTAA) is common. However, the spatial and temporal relationships between stiffness, aortic size, and growth in aTAA remain unclear.
Methods And Results: In this single-centre retrospective study, we utilized vascular deformation mapping to extract multi-directional aortic motion, aortic distensibility, and aortic growth in a multi-planar fashion from multi-phasic ECG-gated computed tomography angiograms.
