Three- and Four-Dimensional Fetal Echocardiography [PDF]

Fetal Diagnosis and Therapy, 2009
The rapid continuing development of 3-dimensional ultrasound imaging technologies has extended capabilities of fetal cardiac scanning beyond 2-dimensional imaging technologies and now provides a wide array of analytic possibilities. The acquisition of the 3D volume information is based on initial application of 2-dimensional imaging techniques ...

Real-time three-dimensional ultrasound : a valuable new tool in preoperative assessment of complex congenital cardiac disease [PDF]

, 2003
Evaluating complex cardiac defects in small children preoperatively requires multiple diagnostic procedures including echocardiography, and also invasive methods such as cardiac catheterisation, computer-tomography and magnetic resonance imaging.

An Implantable Phototriggered Prodrug Depot Patch Enables Actively Programmable Drug Release for Post‐Myocardial Infarction Therapy

Advanced Science, EarlyView.
An implantable phototriggered prodrug depot patch (iPDP) is presented that enables actively programmable drug release post‐implantation. Covalently conjugated prodrug ensures minimal leakage; illumination parameters serve as a code to precisely control dose per release.

Three-dimensional fetal echocardiography

Progress in Biophysics and Molecular Biology, 1998
The complex anatomy and dynamics of the heart make it a challenging organ to image. The fetal heart is particularly difficult because it is located deep within the mother's abdomen and direct access to electrocardiographic information is difficult.

Assessments of Right Ventricular Volume and Function Using Three-Dimensional Echocardiography in Older Children and Adults With Congenital Heart Disease: Comparison With Cardiac Magnetic Resonance Imaging

, 2009
Background The utility of three-dimensional echocardiography (3DE) for right ventricular (RV) assessment is uncertain in older children and adults with congenital heart disease (CHD), in whom the right ventricle is often dilated and dysfunction is common.

ZER1 Restrains Pressure Overload‐Induced Cardiac Remodeling by Targeting DVL2 for Gly/N‐Degron‐Dependent Degradation

Advanced Science, EarlyView.
Pressure overload suppresses cardiomyocyte ZER1, weakening CRL2Zer1‐mediated DVL2 degradation and allowing DVL2 accumulation. Elevated DVL2 activates CaMKII‐HDAC4‐MEF2C signaling, drives fetal gene reactivation, and promotes pathological remodeling.

Three-dimensional echocardiography of the thoracic aorta [PDF]

European Heart Journal, 1996
The feasibility and diagnostic potential of three-dimensional echocardiography, using transoesophageal multiplane echocardiography for the assessment of thoracic aortic pathology, has not been evaluated.We studied 21 patients (10 women, 11 men), mean age 52.1 years (range 20-78).
