Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

13N-Ammonia PET Can Visualize Improvement of the Left Ventricular MFR by Transcatheter Pulmonary Valve Implantation

open access: yesJACC: Case Reports
The patient was a woman with repaired tetralogy of Fallot. Cardiac magnetic resonance revealed right ventricular enlargement and severe pulmonary regurgitation, and we performed a transcatheter pulmonary valve implantation.

Fetal Diagnosis of Hypoplastic Left Heart Syndrome With Restrictive Atrial Septum—Atrial Septal Morphology, Associated Lung Disease and Outcomes

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective Fetuses with hypoplastic left heart syndrome (HLHS) and restrictive/intact atrial septum (RAS) have high mortality, partly due to pulmonary lymphangiectasia (PL). This study aimed to characterize atrial septal morphology in fetuses with HLHS and RAS and evaluate the impact of fetal intervention on PL and outcomes.

Quadruple valve replacement in a patient with severe rheumatic heart disease

open access: yesEcho Research and Practice, 2018
We present a patient with rheumatic heart disease involving all the heart valves. An intraoperative transoesophageal echocardiography confirmed severe mitral stenosis, severe aortic regurgitation, severe tricuspid regurgitation and stenosis, and severe ...

Evolving Features of RASopathies Among Pregnancies With Abnormal Fetal Fluid Collections

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective We aimed to characterize the fetal features across gestation and describe genotype‐phenotype correlations for pregnancies with fetal RASopathies that were more severely affected as they presented with at least one abnormal fluid collection.

Handmade Trileaflet Valve Design and Validation for Pulmonary Valved Conduit Reconstruction Using Taguchi Method and Cascade Correlation Machine Learning Model

open access: yesIEEE Access, 2018
Pulmonary valve diseases in children and adults include different degrees of stenosis, regurgitation, or congenital defects. Valve repair or replacement surgery is used to treat valvular dysfunction and to improve regurgitations flow for pulmonary valve ...

CRPPA exon 6–9 deletion as a founder mutation in Chinese patients with dystroglycanopathy

open access: yesPediatric Investigation, EarlyView.
Analysis of sixteen Chinese dystroglycanopathy patients reveals a founder mutation (CRPPA exon 6–9 deletion) in 25% of cases and expands the phenotypic spectrum from severe muscle‐eye‐brain disease to limb‐girdle muscular dystrophy. ABSTRACT Importance Dystroglycanopathies (DGPs) are a group of muscular dystrophies with abnormal glycosylation of ...

Right ventricular Hemodynamic Alteration after Pulmonary Valve Replacement in Children with Congenital Heart Disease [PDF]

open access: yesJournal of Cardio-Thoracic Medicine, 2015
Introduction:  In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest.

The effects of breath-holding on pulmonary regurgitation measured by cardiovascular magnetic resonance velocity mapping

open access: yesJournal of Cardiovascular Magnetic Resonance, 2009
Background Pulmonary regurgitation is a common and clinically important residual lesion after repair of tetralogy of Fallot. Cardiovascular magnetic resonance (CMR) phase contrast velocity mapping is widely used for measurement of pulmonary regurgitant ...
