¿Qué es una comunicación interauricular?
The evaluation of the IVC rim is fundamental Figure 8B , because PTC would be very challenging in its absence,14 it is, however, usually the most diffcult to visualize and measure, and retrofexion of the probe may help when it is not visible in the standard bi-caval view.
It is necessary to perform a slight retroflexion of the probe to obtain a view of both the lower end of the ASD and the CS. The presence of multiple defects of the inter-atrial septum have been reported in 7.
In such cases, the device should be implanted in the largest defect, with the smaller adjacent septal defect being enclosed in the area covered by the two disks, hence being occluded by the same device. A major concern in the presence of two separate septal defects Figure 10 is the possibility of missing other supplementary defects.
In these cases, it has been suggested to infate two balloons simultaneously under TEE guidance and to exclude a possible third atrial septal defect with CD assessment. CD is used to image fow through the ASD and the balloon is then gently pulled back, at which stage color fow on the TEE will disappear when balloon occlusion is complete.
While maintaining firm but not undue pressure on the septum and under continuous TEE guidance, the balloon is slowly defated until it pops through the defect into the right atrium. The amount of contrast needed to infate the balloon to this diameter is carefully recorded and the balloon is then completely defated and withdrawn from the patient.
Afterwards, it is re-infated to the SBD volume and measured against a sizing plate. It is important to have a good alignment when doing the measurement of the SBD, because misalignment will produce incorrect measurements.
The ideal image is that of a figure "8" see below. In most centers, the static balloon measurement technique is used. This typically creates an indentation sometimes minimal on the balloon Figure Overstretching of the ASD should be avoided to prevent erosion related to the utilization of oversized devices.
The main advantage of this technique is its short inflation-deflation cycle, making the procedure much simpler. It is important to recognize that only when the largest diameter is strictly craneo-caudal in direction, will it truly estimate the full size of the defect, achieving a figure "8" pattern view. The diameter of the indentation can also be measured with fuoroscopy Figure 12 using calibration markers on the balloon catheter.
SBDs by both methods are compared and measurements are repeated if there is a greater than 1 mm discrepancy. However, some operators prefer devices mm greater than the measured SBD22 and up to mm greater than the SBD in the presence of large defects, in defects with a deficient or absent Ao, in defects with an aneurismal septum or in the presence of multiple defects.

Special considerations In older patients, left diastolic ventricular dysfunction associated with elevated flling pressures is observed and may lead to secondary pulmonary hypertension. In these cases, the atrial septal defect, functioning as an over-fow, may mask the presence of left ventricular diastolic dysfunction by an enhanced left-to-right shunt.
If such a mechanism is suspected, temporary balloon occlusion of the defect should permit its unmasking. In order to ensure stability during device delivery, the interventional cardiologist will position a supportive guidewire, through the ASD and left atrium, most often into the left upper pulmonary vein LUPV.
Given the fragility of the left atrial appendage, it is essential to avoid entering this thin-walled structure with catheters or the stiff guidewire, because this could cause perforation and lead to pericardial effusion. After having loaded the device in the delivery sheath, its insertion must be performed under TEE guidance.
It is important to ensure that the tip of the delivery sheath is located in the left atrium, before deploying the left atrial disk of the closure device, in order to avoid deployment in the LUPV, the left ventricle or the left atrial appendage as this could cause deformation of the device, device entrapment or perforation of the atrial wall. Once the correct distal sheath position and the partially opened left disc position are confirmed by TEE, the left disk can be completely deployed Figure The device is then pulled back under TEE guidance toward the IAS so that the lower portion of the device catches the Ao or, in its absence, it encroaches the base of the aortic root.
Thereafter the device is pulled toward the RA, so that its superior portion catches the superior aspect of the ASD Figure When resistance of the septum is encountered and TEE confirms good apposition of the LA disk with the rims of the ASD, the right atrial disk of the prosthesis is opened inside the RA, allowing the prosthesis to grasp the rims of the ASD between its two disks Figure Under TEE guidance, the occluder device is scanned in 2-D and with CD in several views, looking for proper positioning and residual shunts.
The echocardiographer must confirm that both disks are fattened with good apposition, and assess residual shunting. It is not uncommon to have discrete residual central or peri-prosthetic shunts, which usually will disappear after endothelialization of the occluder device Figure When the Ao is absent, a typical "Y" pattern of the device being sandwiched around the AA should be seen Figure Failure to achieve this "Y" pattern of both disks requires device repositioning before release because this could lead to laceration of the aortic wall.
When a large Eustachian valve EV or Chiari network is present, it should be mentioned to the operator because it can cause device entrapment during deployment of the right atrial disk.
This serious complication can be prevented by pushing back the structure using a second catheter. Nearby structures might be compromised after positioning of the occluder device. Mitral valve leafets might be encroached by the occluder device, producing mitral regurgitation in a defect with a defcient AV rim and, infow from the SVC and RUPV might be compromised in a defect with a defcient SVC rim.
The Minnesota maneuver or wiggle is performed prior to release, to ensure stability of the occluder device. After this maneuver, the device is released. A number of different configurations of the magnet were assembled and tested in an effort to minimize the undesired leakage field in the stored-beam region.
We found, in particular, that for nm irradiation s equals 37,6 plus or minus 3. The variant of DORV with intact ventricular septum is very uncommon and may be associated with fetal demise or death immediately after birth.

We have found that there is still small leakage field in the upstream line of the new injection septum. The comunidacion estimate is based on detailed simulations that analyze the beam-matter interaction and provide a determination of the shadowing effect of the dummy septum. Report of a unique case. There were no signs and symptoms of recurrence after a year of followup.
Results Among the analyzed patients, presented congenital heart disease High signal intensity of the septum pellucidum on proton density- weighted image may be caused by transependymal CSF migration in the patients with hydrocephalus, and considered as an additional finding of hydrocephalus in the cases of ventriculomegaly. The interventricular septum has often been found to display dyskinetic, or paradoxical motion by echocardiographic studies.
She was treated with lateral rhinotomy and wide excision followed by lnterauricular.Figure 2. Can J Cardiol ;e A comparison of the right and left auricular, capillary and pulmonary artery pressures in nine patients with auricular septal defect.
With slight probe rotation to the right clockwise rotation of the shaft of the probe , the IVC and the superior vena cava SVC are seen. It is not uncommon to observe a change of position of the device en bloc with the inter-atrial septum, as tension is relaxed Figure The defect must have a favorable anatomy, with adequate rims of at least 5 mm to anchor the prosthesis.
