A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

Advanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Neural Fields for Highly Accelerated 2D Cine Phase Contrast MRI

Advanced Science, EarlyView.
ABSTRACT 2D cine phase contrast (CPC) MRI provides quantitative information on blood velocity and flow within the human vasculature. However, data acquisition is time‐consuming, motivating the reconstruction of the velocity field from undersampled measurements to reduce scan times. In this work, neural fields are proposed as a continuous spatiotemporal

Acute Aortic Regurgitation [PDF]

Circulation, 2012
Aortic regurgitation (AR) is characterized by regurgitation of blood from the aorta to the left ventricle (LV) during diastole and is attributable to diverse congenital and acquired abnormalities of the aortic valve or the wall of the aortic root. AR can be either chronic or acute.

Clinical utility of pharyngeal high‐resolution manometry with impedance for upper esophageal sphincter dysfunction in gastroenterology

Advances in Digestive Medicine, EarlyView.
Abstract Pharyngeal high‐resolution manometry with impedance (P‐HRM‐I) is an established assessment method used to evaluate pharyngeal swallowing. It provides precise quantification of swallowing biomechanics that enable the detection of alterations in swallowing physiology.

Integrating Diagnostic Tools for Early Recognition of Rumenitis in a Neonatal Calf

Animals
Rumenitis is an inflammatory condition of the rumen, typically seen in adult cattle managed on high-energy diets. In calves, it is uncommon and often linked to ruminal drinking due to esophageal groove dysfunction.

Gastrointestinal Manifestations in Rubinstein‐Taybi Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Rubinstein–Taybi syndrome is a rare genetic condition associated with a wide range of physical, cognitive, and developmental impairments, yet its gastrointestinal manifestations remain poorly characterized. Case reports and small series suggest a high prevalence of gastroesophageal reflux, constipation, dysphagia, and nutritional compromise ...

Acute Valvular Regurgitation [PDF]

Circulation, 2009
Acute severe valvular regurgitation is a surgical emergency, but accurate and timely diagnosis can be difficult. Although cardiovascular collapse is a common presentation, examination findings to suggest acute regurgitation may be subtle, and the clinical presentation may be nonspecific.

The Novel ACTC1 p.Gly50Ser Variant Is Associated With Arrhythmia and Secondary Features of HCM Without Hypertrophy

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The key diagnostic criterion for hypertrophic cardiomyopathy is the presence of otherwise unexplained hypertrophy. Current definitions of HCM rely on specific thresholds to establish a diagnosis, while guideline directed risk stratification algorithms take its magnitude into consideration.
