Comunicación interauricular

Long-term follow up of secundum atrial septal defect closure with the amplatzer septal occluder. 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needed to infate the balloon to this diameter is carefully recorded and the balloon is then completely defated and withdrawn from the patient. 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 ingerauricular “8” pattern view.

Hoffman JI, Christianson R. Transesophageal echocardiography multimedia manual: Fierre Am Coll Cardiol ;6: For reasons of clarity, anatomic connotations are used herein.

Diagnosis and classification of atrial septal aneurysm by two-dimensional echocardiography: This serious complication can be prevented by pushing back the structure using a second catheter. Factors affecting nonsurgical closure of large secundum defects using the Amplatzer occluder.

Morphologic, mechanical, conductive, and hemodynamic changes following transcatheter closure of atrial septal defect. From the mid-esophageal 4-chamber view, the probe should be pulled out with a slight right rotation to permit the localization of the right upper pulmonary vein RUPV rim at comunicaicon upper-esophageal level Figure 5.

This typically creates an indentation sometimes minimal on comunicavion balloon Figure Transcatheter closure of secundum atrial septal defects using the new self-centering amplatzer septal occluder: The main advantage of this technique is its short inflation-deflation cycle, making the procedure much simpler.

Sometimes the Ao is very small, or even absent Figure 7this finding makes the procedure more challenging but does not, preclude PTC intetauricular the defect. Percutaneous closure of an interatrial communication with the Amplatzer device. Nearby structures might be compromised after positioning of the occluder device.


To simplify this classification we refer to Table 1. The ideal image is that of a figure “8” see below. Measurement of atrial septal defect size: Transcatheter occlusion of complex atrial septal defects. Br Heart J ; 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.

The device is then interauircular 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. Congenit Heart Dis ;5: A major concern in the presence of two separate septal defects Figure 10 is the possibility of missing other supplementary defects.

J Am Soc Echocardiogr intersuricular For example, some authors describe the “antero-septal comunicacoin, which corresponds anatomically to the aortic rim Ao.

Quantitative analysis of the morphology of secundum-type atrial septal defects and their dynamic change using transesophageal three-dimensional echocardiography. It interauricylar not uncommon to have discrete residual central or peri-prosthetic shunts, which usually will disappear after endothelialization of the occluder device Figure Defects up to 40 mm in diameter with firm and adequate rims have been closed successfully via PTC, as have multiple ASDs and those associated with atrial septal aneurysms.

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.

Long-term follow up should be performed with TTE at three, six and 12 months after the procedure and when clinically indicated thereafter. Follow up should include transthoracic echocardiography TTE the day following device deployment.

In most centers, the static balloon measurement technique is interauriular. The role of echocardiography during interventional procedures is well documented 3,4 and several techniques have been described co,unicacion the guidance of PTC of ASD.

Can J Cardiol ; Transesophageal echocardiography is also important during the procedure to guide the deployment of the device. Device preparation for delivery is an important process of PTC and requires a meticulous approach on behalf of the interventional cardiologist Figure Follow up The presence of residual shunts should be reassessed; this could be achieved with contrast echocardiography with agitated normal saline, which opacifies the right sided cardiac chambers and may demonstrate the un-opacified jet of the left to right shunt.


It is important to have a good alignment when doing the measurement of the SBD, because misalignment will produce incorrect measurements. After having loaded the device in the delivery sheath, its insertion must be performed under TEE guidance. Arch Inst Cardiol Mex ; Absent posteroinferior and anterosuperior atrial septal defect rims: The minimal two-dimensional measurement is taken. Transcatheter closure of multiple atrial septal defects.

The device and adjacent structures are evaluated 8 to rule out device 14 mal-positioning, interference with aortic, mitral, or tricuspid valvular function, caval, CS, or pulmonary venous return obstruction, and pericardial effusion. Initial results and value of two- dd three-dimensional transoesophageal echocardiography.

Comparison of intracardiac echocardiography versus transesophageal echocardiography guidance for percutaneous transcatheter closure of atrial septal defect. Failure to achieve this “Y” pattern of both disks requires device repositioning before release because this could lead to laceration of the aortic wall.

It is important to ensure that the tip of the delivery sheath is located in the inteeauricular 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.

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. The presence of multiple defects of the inter-atrial septum have been reported in 7.
