Background The internal diameter of the patent ductus arteriosus (PDA) measured on transthoracic echocardiography (TTE) is commonly used in determining the need for treatment in clinical practice and ...

Functional echocardiography permits bedside assessment of a patent ductus arteriosus (PDA) in the newborn infant. Both ductal diameter and flow pattern are used to assess PDA clinical significance.

Accurate diagnosis of a PDA requires echocardiography. Echocardiography together with Doppler and color Doppler allows assessment of patency, diameter of the DA (using color Doppler), and ...

Colour Doppler echocardiography, on the other hand, is a useful tool to assess the patency of ductus arteriosus and the direction of PDA shunt flow. Actual size of shunt flow and haemodynamic changes ...

Tiles that fill two- and three-dimensional spaces with no gaps—including triangles, squares, hexagons, cubes, and other ...

Abnormal septal motion on M mode echocardiography was seen in eight of 16 patients soon after non-surgical closure of the ductus arteriosus ... The left ventricular end diastolic diameter before ...

The BIB balloon was used with a diameter = the size of the isthmus. In 1 pt (PDA ligation) the st did not expand ... with free pulmonary insufficiency and a gradient <30mmHg on echocardiography. PVP ...

Compared to the 5th-generation Echo Dot, the Echo Pop features a smaller, more compact size, making it a perfect speaker for a small space. The Echo Pop also comes with a larger speaker driver and ...

10 Prepregnancy echocardiography should be performed in every woman ... 3 Class I consists of mild congenital heart disease such as a small patent ductus arteriosus or mitral valve prolapse, and ...

Objective The mean closure time of the ductus arteriosus (DA) in full-term neonates is presumed ... the clinical determinants that influence DA closure remain unknown. Methods Echocardiography was ...

The use of serial echocardiography has dramatically enhanced the understanding of the natural history of the PDA, and it is clear that, in most situations, the diameter or degree of constriction ...
