La elevación transitoria del segmento ST en derivacio- nes inferiores ha sido descrita como rara complicación.

The potential of paradoxical embolus may be assessed by increasing right sided pressures with the Valsalva maneuver. Canadian Cardiovascular Society Consensus Conference on the management of adults with congenital heart disease: A major concern in the presence of two separate septal defects Figure 10 is the possibility of missing other supplementary defects. 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.

The size of the ASD changes during the cardiac cycle; the maximal ASD diameter must be measured at the end of ventricular systole.

It is not uncommon to have discrete residual central or peri-prosthetic shunts, which usually will disappear after endothelialization of the occluder device Figure The purpose of this paper is to review the usefulness of multiplanar transesophageal echocardiography before, during and after percutaneous transcatheter closure of secundum atrial septal defects.

J Am Coll Cardiol ;6: In most centers, the static balloon measurement technique is used. 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. Measurement of atrial septal defect size: Initial results and value of two- and three-dimensional transoesophageal echocardiography.


The defect must have a favorable anatomy, with adequate rims of at least 5 mm to anchor the prosthesis. 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.

Arch Inst Cardiol Mex ; The diameter of the indentation can also be measured with fuoroscopy Figure 12 using calibration markers on the balloon catheter.

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. To simplify this classification we refer to Table 1.

J Am Coll Cardiol ; Immediate post procedural evaluation Comunicaciin thorough evaluation for presence of residual shunts is performed for future correlation.

Comunicación interauricular (para Niños)

Thereafter the device is pulled toward the RA, so that its superior portion catches the superior aspect of the ASD Figure 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.

Factors affecting nonsurgical closure of large secundum defects using the Amplatzer occluder. TEE is the ideal imaging and assessment tool to evaluate and guide procedures and determine immediate procedural success, while ruling out complications.

Long-term follow up should be performed with TTE at three, six and 12 months after the procedure and when clinically indicated thereafter. Left ventricular conditioning in the elderly patient to prevent congestive heart failure after transcatheter closure of atrial septal defect.

Catheter closure of atrial septal defects with deficient inferior vena cava rim under transesophageal echo guidance. Transvenous closure of moderate and large secundum atrial septal defects in adults using the Amplatzer septal occluder.


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. Transcatheter closure of multiple atrial septal defects.

J Invasive Cardiol ; Acultos ASD closure is followed by near normalization of heart structure and function. Quantitative analysis of the morphology of secundum-type atrial septal defects and their dynamic change using transesophageal three-dimensional echocardiography.

Several authors have referred to these edges with anatomical connotations and others with spatial connotations. 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 adiltos pulmonary artery pressure dropped to near normal levels during the following few months. Defects up to interauriular 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.

It is critical to recognize the nomenclature comunicaciion understand the anatomical comknicacion of the rims or edges bordering the ASD Figure 2. Implications for surgical treatment. Can J Cardiol ; Current indications for ASD closure are out of the scope of this paper and can be reviewed elsewhere. In older patients, left diastolic ventricular dysfunction associated with elevated flling pressures is observed and may lead to secondary pulmonary hypertension.

Catheter Cardiovasc Interv ; Transcatheter closure of secundum atrial septal defects using the new self-centering amplatzer septal occluder:
