Übersetzung für "Linke atrium" in Englisch

The-the left atrium's too small.

Moreover, FIG. 1 shows the left atrium LA and the mitral valve MK.

The condition in which blood flows in the wrong direction inside the heart, past the mitral valve, and leaks back into the left atrium.

SafeSept provides a precise perforation of the interatrial septum and a safe guidance of the standard transseptal needle into the left atrium.

The foramen ovale opens like a valve and can direct the blood stream that comes from below directly into the left atrium.

It is noted that the invention can also be used with a line and/or line configuration provided for use in the left atrium if the line is passed through the septum into the left atrium.

The triple-chamber pacemaker shown in FIG. 1 further entails the possibility of also stimulating the left atrium.

In cardioversion, the largest possible atrial muscle mass, in particular including the left atrium, is covered by the electric field.

In either case, with the further development of the heart, more and more of the pulmonary veins are incorporated into the left atrium, so that at the end of the embryonic period 4 independent pulmonary veins empty into the atrium.

The individual pulmonary veins that have been engendered become incorporated into the left atrium and finally 4 independent pulmonary veins empty into the heart.

Due to the higher pressure of the blood in the inferior vena cava, more blood flows from it directly into the left atrium via the foramen ovale.

Due to the higher pressure of the blood in the inferior vena cava, more blood flows from it directly into the left atrium via the foramen ovale.

Thus all of the blood regurgitates into the left atrium via the foramen ovale and the lungs get perfused retrogradely via a very wide ductus arteriosus.

Showed a mass in the left atrium.

This is why SAM also leads to an enlarged left atrium.

The second half of the signal values of the comparison pattern which contain the second maximum thereof are then calculated with signal values which originate from the left atrium.

For special applications, such as so-called bi-atrial or multi-site stimulation, it can be useful to position pacemaker stimulation or sensing electrodes in a vessel near the heart, particularly in the coronary sinus, because an electrode implantation in the left atrium is particularly problematic.

The auxotonically measured contractility (maximum contractile force) was also followed (papillary muscle, left atrium).

One aspect of signal analysis is analysis of the time relationships between the left and right atria or the left and right ventricles of a heart.

If two separate channels are available for the two heart chambers, the conduction time for example from the right to the left atrium can be implemented by processing a signal value sequence which is composed of values of both signal pick-ups and which begins with the signal values of the right atrium and continues with those of the left atrium.

Either direct methods of pressure measurement in the pulmonary vein, left atrium, or ventricle are studied here, or indirect methods of impedance cardiography are being pursued.

For example, if blood in the right atrium contains more oxygen than it should, this means that blood has shunted from the left atrium, probably through an atrial septal defect.

First there is a direct connection between the right and left atria in that the blood from the right atrium flows directly into the left via the foramen ovale and thus goes around the pulmonary circulation system.

However, the mitral valve of the heart, which is the valve between the left atrium and the left ventricle, is not very suitable for a replacement prosthesis anchored mainly by a radial expansion force of a stent positively (by friction) anchored on the spot, since a widening of the annulus is to be avoided.

The annular body 12 is positioned with its central portion, that is the portion of reduced diameter D3, in the annulus of the mitral valve 18 . FIG. 2 thus illustrates the use of the valve prosthesis between the left atrium and left ventricle.

For example, the method is suitable for recognizing at least one pulmonary vein ostium (e.g., all four or five or six pulmonary vein ostia) in a left atrium.

The method referring to a left atrium is shown as an example for a hollow organ, where the aim is to recognize pulmonary vein ostia (e.g., five: two left and three right).

A suitable method is described, for example, in the article by Telea et al. (see further above), where a two-stage approach has been selected: a surface skeleton of the left atrium (LA) is computed, and subsequently, a curve skeleton is formed from the surface skeleton.

One example from electrophysiology (EP) is the position of the pulmonary vein (PV) ostia and of the left atrial appendage (LAA) in a left atrium.

Thus, for example, live fluoroscopy images through the triangle mesh and the anatomical landmarks (e.g., left atrium with pulmonary vein ostia) may be displayed overlaid.
