In most centers, the static balloon measurement technique is used.

SBDs by both methods are compared and measurements are repeated if there is a greater than 1 mm discrepancy. Transvenous closure of moderate and large secundum atrial septal defects in adults using the Amplatzer septal occluder.

Congenit Heart Dis ;5: The presence of a defect opening in the septum that separates the two atria of the heart. TEE during device positioning, deployment, and release. Definition NCI The presence of a defect opening in the septum that separates seucndum two atria of the heart.

Congenital heart disease in a cohort of 19, births with long-term follow-up. A ASD closed with Amplatzer device D in a patient with an adequate aortic rim B Amplatzer septal occluder “encroaching” the aorta at the level of the aortic valve AoV in a patient with absence of an aortic rim. Transesophageal echocardiography imaging techniques,including their role in patient selection, procedural guidance and immediate assessment of technical success and complications are described and discussed in this review.

TEE is the ideal imaging and assessment tool to evaluate and guide procedures and determine immediate procedural success, while comunicadion out complications.

Left ventricular conditioning in the elderly patient to prevent congestive heart failure after transcatheter closure of atrial septal defect. The Amplatzer septal occluder device is “encroaching” the aorta at the level of the aortic valve AoV.

The indentation caused by the defect is also measured by fluoroscopy. Under TEE guidance, the occluder device is scanned in 2-D and with CD in several views, looking for proper positioning and residual shunts. Percutaneous closure of significant shunting associated with secundum ASD represents an attractive less-invasive alternative therapy to surgery and is being increasingly performed worldwide.

It is critical to recognize the nomenclature and understand the anatomical disposition of the rims or edges bordering the ASD Figure 2. Once the device is well aligned, it is pulled toward the RA allowing correct apposition of the device on all the rims of the defect. After having loaded the device in the delivery sheath, its insertion must be performed under TEE guidance. Special considerations In older patients, left diastolic ventricular dysfunction associated with elevated flling pressures is observed and may lead to secondary pulmonary hypertension.


Factors affecting nonsurgical closure of large secundum defects using the Amplatzer occluder. 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 Related links to external sites from Bing.

The relation with the aorta at the level of the aortic valve AoV is demonstrated. Transcatheter closure of multiple atrial septal defects. With slight probe rotation to the right clockwise rotation of the shaft of the probethe IVC and the superior vena cava SVC are seen. 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.

Transesophageal echocardiography; Percutaneous closure; Atrial septal defect; Canada. The evaluation of the IVC rim is fundamental Figure 8Bbecause PTC would be very challenging in its absence, 14 it is, however, usually the most difficult to visualize and measure, and retroflexion of the probe may help when it is not visible in the standard bi-caval view.

For example, some authors describe communicacion “antero-septal rim”, which corresponds anatomically to the aortic rim Ao. In most centers, PTC is performed under general anesthesia with echocardiographic TEE guidance because intra-cardiac echo without anesthesia remains an expensive option.

Respective schematic representations, with the anatomic correlations are also shown. 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 comuniacion defect with a defcient SVC rim.

Atrial Septal Defect

The schematic representations, with anatomic correlations are shown under the respective potos black double arrowhead representing the sizing balloon diameter. It is important to be aware of the potential long term complications such as encroachment of mitral or aortic valve leaflets, impairment of flow from the pulmonary veins, reactive or hemorrhagic pericarditis, and migration or dislodgement of the comynicacion.


Am J Cardiol ; 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. A Mid-esophageal TEE in the short-axis AV view depicting a secundum ASD of 20 mm diameter, the correct alignment with the sizing balloon is demonstrated, achieving a waist in the middle white double arrowheadresulting in a figure “8” pattern.

In these cases, it has been suggested to inflate two balloons simultaneously under TEE guidance and to exclude a possible third atrial septal defect with CD assessment. When a large Eustachian valve EV or Chiari network is interaurkcular, it should be mentioned to the operator because it can cause device entrapment during deployment of the right atrial disk.

TEE upper-esophageal 4-chamber view with rightward clockwise rotation of the probe revealing an adequate right upper pulmonary vein RUPV rim of 15 mm green line. Transesophageal echocardiography plays a critical role before the procedure in identifying potential candidates for percutaneous closure and to ocmunicacion those with unfavorable anatomy or associated lesions, which could not be addressed percutaneously. A Mid-esophageal bi-caval view at 97 degrees, an adequate SVC rim is noted, measuring 13 mm green line.

The relation of the device with the aorta at the level of the AoV is depicted Abbreviations as follows: The schematic representations, with anatomic correlations are shown under the respective photos.

In summary, the baseline TEE must meet the criteria described in Table 2 in order for the patient to be eligible for percutaneous closure. They include ostium primum, ostium secundum, sinus venosus, and coronary sinus defects. Quantitative analysis of the morphology of secundum-type atrial septal defects and their dynamic change secudum transesophageal three-dimensional echocardiography.
