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. Arch Inst Cardiol Mex ; 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 not uncommon to observe a change of position of the device en bloc with the inter-atrial septum, as tension is relaxed Figure Transesophageal echocardiography multimedia manual: 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.
Left ventricular conditioning in the elderly patient to prevent congestive heart failure after transcatheter closure of atrial septal defect. Current indications for ASD closure are out of the scope of this paper and can be reviewed elsewhere. The ideal scenario for PTC is a single ASD with a maximal diameter of less than 20 mm, 8 with firm and adequately sized rims. Transvenous closure of moderate and large secundum atrial septal defects in adults using the Amplatzer septal occluder.

Percutaneous transcatheter closure is indicated for ostium secundum atrial septal defects of less than 40 mm in maximal diameter. Abnormal septal motion of the inter-ventricular septum is expected to normalize shortly after the procedure. Can J Cardiol ; Diagnosis and classification of atrial septal aneurysm by two-dimensional echocardiography: 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 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.
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 comuniacion Percutaneous closure of secundum atrial septal defect in adults a single center experience with the amplatzer septal occluder. SBDs by both methods are compared and measurements are repeated if there is a greater than 1 mm discrepancy.
It is critical to recognize the nomenclature and understand the anatomical disposition of the rims or edges bordering the ASD Figure 2.
Comunicación interauricular (para Niños)
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. 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.
Overstretching of the ASD should be aultos to prevent erosion related to the utilization of oversized devices. A major concern in the presence of two separate septal defects Figure 10 is the possibility of interaurifular other supplementary defects.
Percutaneous closure of significant shunting associated with secundum ASD represents an attractive less-invasive alternative therapy to surgery and is being increasingly performed worldwide. In these cases, it has been suggested to interaurocular two balloons simultaneously under TEE guidance and to exclude a possible third atrial septal defect with CD assessment.
The Minnesota maneuver or wiggle is performed prior to release, to ensure stability of the occluder device. A thorough evaluation for presence of residual shunts is performed for future correlation. The potential of paradoxical embolus may be assessed by increasing right sided pressures with the Valsalva maneuver.
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 ideal image is that of a figure “8” see below.
It is not uncommon to have discrete residual central or peri-prosthetic shunts, which usually will disappear after endothelialization of the occluder device Figure Afterwards, it is re-infated to the SBD volume and measured against a sizing plate.
Comuniccion of secundum atrial septal defects with the Amplatzer septal occluder device: The main advantage of this technique is its short inflation-deflation cycle, making the procedure much simpler. The defect must have a favorable anatomy, with adequate rims of at least 5 mm to anchor the prosthesis.
Cathet Cardiovasc Diagn ; Percutaneous closure of an interatrial communication with the Amplatzer device. This serious complication can be prevented by pushing interwuricular the structure using a second catheter. To simplify this classification we refer to Table 1. In older patients, left diastolic ventricular dysfunction associated with elevated flling pressures is observed and may lead to secondary pulmonary hypertension.
Morphologic, mechanical, conductive, and hemodynamic changes following transcatheter closure of atrial septal defect. Eur Heart J ;
