Toward optimal inline respiratory motion correction for in vivo cardiac diffusion tensor MRI using symmetric and inverse‐consistent deformable image registration

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose This study aims to develop a free‐breathing cardiac DTI method with fast and robust motion correction. Methods Two proposed image registration‐based motion correction (MOCO) strategies, MOCONaive and MOCOAvg, were applied to diffusion‐weighted images acquired with M2 diffusion gradients under free‐breathing.

Contactless cardiac gating at 0.55T using high‐amplitude pilot tone with interference cancellation (HAPTIC)

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To enable contactless cardiac gating at 0.55T using pilot tone (PT). Current PT methods are unable to extract weak motions, including cardiac motion, at lower B0 field strengths (<1.5T). Methods We utilize high‐amplitude pilot tone with interference cancellation, termed HAPTIC.

Myocardial Perfusion Defects in Hypertrophic Cardiomyopathy Mutation Carriers

Journal of the American Heart Association, EarlyView., 2021
Background Impaired myocardial blood flow (MBF) in the absence of epicardial coronary disease is a feature of hypertrophic cardiomyopathy (HCM). Although most evident in hypertrophied or scarred segments, reduced MBF can occur in apparently normal segments.

Prenatal Predictors of Early Intervention in Simple Tetralogy of Fallot: A Retrospective Multi‐Centre Study

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Prenatal predictors of early postnatal intervention in tetralogy of Fallot (ToF) remain uncertain. This study aimed to identify prenatal cardiac and non‐cardiac predictors of disease severity associated with early intervention in ToF.

Age‐Dependent Correlation of Pulmonary Function Impairment and Aortic Arch Stiffness in Mice

Pediatric Discovery, EarlyView.
This study examined the relationship between aortic arch stiffness and lung function in aging mice. Multiple linear regression modeling showed moderate to strong correlations between the rise in aortic arch stiffness and changes in lung function as the mice progressively aged.

Nonlinear control of a hybrid pneumo‐hydraulic mock circuit of the cardiovascular system

International Journal of Robust and Nonlinear Control, EarlyView.
Abstract Hybrid cardiovascular mock circuits (HMC), designed for dynamic testing of Ventricular Assist Devices (VAD), offer physiologic accuracy by sequestering model complexity in silico and ease of construction by reducing number of model elements in vitro.

Treatment of focal junctional tachycardia using ivabradine in a dog

Veterinary Record Case Reports, EarlyView.
Abstract A 10‐year‐old labrador retriever was referred as an emergency due to ascites and lethargy. Physical examination revealed a regular tachycardia at 160 beats per minute with a Grade 3/6, left apical systolic heart murmur. The dog was diagnosed with severe myxomatous mitral valve disease with biventricular congestive heart failure (mild pulmonary

Elevated Serum Immunoglobulin G1 Levels and Left Ventricular Diastolic Dysfunction in Anti‐Centromere Antibody–Positive Patients With Lower Extremity Arterial Disease: A Cross‐Sectional Study

The Journal of Dermatology, EarlyView.
ABSTRACT This cross‐sectional pilot study investigated the clinical characteristics of anti‐centromere antibody (ACA)–positive patients with below‐the‐knee arterial disease. Sixteen ACA‐positive patients (mean age 69 ± 10 years; 94% women) underwent contrast‐enhanced computed tomography evaluation, with arterial damage scored using the Global Limb ...
