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.

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).

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.

Utility of real-time three-dimensional transesophageal echocardiography in evaluating the success of percutaneous transcatheter closure of mitral paravalvular leaks. [PDF]

, 2010
Background: The percutaneous closure of mitral paravalvular leaks has been reported in patients who are poor operative candidates. Unsuccessful percutaneous closure of leaks may be related to morphologic characteristics of the defects.

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.

Transthoracic three-dimensional echocardiography for the assessment of straddling tricuspid or mitral valves [PDF]

, 2000
Background The advent of 3D echocardiography has provided a technique which, potentially, could afford significant additional information over conventional cross-sectional echocardiography in the assessment of patients with straddling atrioventricular ...

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.

Effects of anesthesia on conventional and speckle tracking echocardiographic parameters in a mouse model of pressure overload [PDF]

, 2015
Genetically‑modified mice are widely applied in cardiovascular studies as model organisms. Echocardiography is a key tool for evaluating cardiac and hemodynamic functions in mice.

A Pathology‐Instructed Theranostic Platform with Mechanoadaptive and ROS‐Powered Nanobreathing Functions for Precision Myocardial Repair

Advanced Science, EarlyView.
We developed a pH responsive theranostic serum albumin hydrogel named BST, functionalized with MRI and CT probes and loaded with mitochondria targeted CAT‐SOD nanogels, that rapidly self repairs and mechanically stabilizes the infarcted myocardium, releases therapeutic nanogels and albumin under hypoxia induced acidosis to clear mitochondrial ROS ...
