Conclusions Percutaneous closure of significant shunting associated with secundum ASD represents an attractive less-invasive alternative therapy to surgery and is being increasingly performed worldwide. The ideal scenario for PTC is a comunicaicon ASD with a maximal diameter of less than 20 mm, 8 with firm and adequately sized rims.
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.
Measurement of atrial septal defect size: 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. It is not uncommon to have discrete residual central or peri-prosthetic shunts, which usually will disappear after endothelialization of the occluder device Figure Cathet Cardiovasc Diagn ; Failure to achieve this “Y” pattern of both disks requires intetauricular repositioning before release because this could lead to cuerre of the aortic wall.
The mid-esophageal bi-caval interaurivular provides an excellent view of the inter-atrial septum, allowing interrogation of the septum with CD. To simplify this classification we refer to Table 1. It is recommended to choose a device that is the same size of the SBP to prevent oversizing and erosions. Nearby structures might be compromised after positioning of the occluder device.
J Am Coll Cardiol ; Given the fragility of the left atrial appendage, it is essential to avoid entering this interrauricular structure with catheters or the stiff guidewire, because this could cause perforation and lead to pericardial effusion. TEE assessment of ASD includes evaluation of the number and localization of the defect sdimensions and adequacy of the rims, direction and severity of the shunt, and the presence of possible associated defects. Percutaneous closure of an interatrial communication interauricuoar the Amplatzer device.
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 Percutaneous closure of secundum atrial septal defect in adults a single center experience with the amplatzer septal occluder.
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. 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.
Transesophageal echocardiography plays a critical role before the procedure in identifying potential candidates for percutaneous closure and to exclude those with unfavorable anatomy or associated lesions, which could not be addressed percutaneously. SBDs by both methods are compared and measurements are repeated if there is a greater than 1 mm discrepancy.
Long-term follow up of secundum atrial septal defect closure with the amplatzer septal occluder. 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.

Closure of secundum atrial septal defects with the Amplatzer septal occluder device: The diameter of the indentation can also be measured with fuoroscopy Figure 12 using calibration markers on the balloon catheter. In these comuniaccion, it has been suggested to infate two balloons simultaneously under TEE guidance and to exclude a possible third atrial septal defect with CD assessment.

Masked left ventricular restriction in elderly patients inteeauricular atrial septal defects: Abstract The purpose of this paper interauriuclar to review the usefulness of multiplanar transesophageal echocardiography before, during and after percutaneous transcatheter closure of secundum atrial septal defects.
Follow up The presence of residual shunts should be reassessed; this could be achieved with contrast echocardiography with agitated normal saline, which opacifies df right sided cardiac chambers and may demonstrate the un-opacified jet of the left to right shunt.
A thorough evaluation for presence of residual shunts is performed for future correlation. Comparison niterauricular intracardiac echocardiography versus transesophageal cmounicacion guidance for percutaneous transcatheter closure of atrial septal defect. Arch Inst Cardiol Mex ; For example, some authors describe the “antero-septal rim”, which corresponds anatomically to the aortic rim Ao.
When the Ao is absent, a typical “Y” pattern of the device being sandwiched around the AA should be seen Figure Transesophageal echocardiography is also important during the procedure to guide the deployment of the device.
The Minnesota maneuver or wiggle is performed prior to release, to ensure stability of the occluder device. However, some operators prefer devices mm greater than the measured SBD 22 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.
It is important to recognize that only when comunicacipn largest diameter is strictly craneo-caudal in direction, will it truly estimate the full size of the defect, achieving a figure “8” pattern view. Percutaneous transcatheter closure is indicated for ostium secundum atrial septal defects of less than 40 mm in maximal diameter. The reversal of RV volume overload has been shown as early as 3 weeks post procedure in children and 9 months in adults, 28 also systolic pulmonary artery pressure dropped to near normal levels during the following few months.
Canadian Cardiovascular Society Consensus Conference on the management of adults with congenital heart disease: Br Heart J ; 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.
Morphological variations of secundum-type atrial septal defects: J Am Soc Echocardiogr ; Diagnosis and classification of atrial septal aneurysm by two-dimensional echocardiography: Device preparation for delivery is an important process of PTC and requires a meticulous approach on behalf of the interventional cardiologist Figure The defect must have a favorable anatomy, with adequate interaurkcular of at least 5 mm to anchor the prosthesis.

The presence of multiple defects of the inter-atrial septum have been reported in 7. Percutaneous closure of significant shunting interaurixular with secundum ASD represents an attractive less-invasive alternative therapy to surgery and is being increasingly performed worldwide.
Special considerations In older patients, left diastolic ventricular dysfunction associated with elevated flling pressures is observed and may lead to secondary pulmonary hypertension.
