It is important to have a good alignment when doing the measurement of the SBD, because misalignment will produce incorrect measurements. The purpose of this paper cirere to review the usefulness of multiplanar transesophageal echocardiography before, during and after percutaneous transcatheter closure of secundum atrial septal defects. This typically creates an indentation sometimes minimal on the balloon Figure Quantitative analysis of the morphology of secundum-type atrial septal defects and their dynamic change using transesophageal three-dimensional echocardiography.
The echocardiographer must confirm that both disks are fattened with good apposition, and assess residual shunting.
J Am Soc Echocardiogr ; 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 dierre disks Figure 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 the upper-esophageal level Ee 5.
Long-term follow up of secundum atrial septal defect closure with the amplatzer septal occluder. Comuincacion role of echocardiography during interventional procedures is well documented 3,4 and several techniques have been described for the guidance of PTC of ASD.
In most centers, PTC is performed under general anesthesia with echocardiographic TEE guidance because intracardiac echo without anesthesia remains an expensive option. The ideal scenario for PTC is a single ASD with a maximal diameter of less than 20 intrrauricular, 8 with firm and adequately sized rims.
Special considerations In older patients, left diastolic ventricular dysfunction associated with elevated flling pressures is observed and may lead to secondary pulmonary hypertension. It is critical to recognize the nomenclature and understand the anatomical disposition of the rims or edges bordering the ASD Figure 2.
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 intrrauricular defcient SVC rim.
After having loaded the device in the delivery sheath, its insertion must be performed under TEE guidance. Sometimes the Ao is very small, or even absent Figure 7this finding makes the procedure more challenging but does not, preclude PTC of the defect. Ijterauricular a large Eustachian valve EV or Chiari network is present, interaurocular should be mentioned to the operator because it can cause device entrapment during deployment of the right atrial disk.
Initial results and value of two- and three-dimensional transoesophageal echocardiography. Catheter closure of atrial septal defects with deficient inferior vena cava cojunicacion under transesophageal echo guidance.
Several authors have referred to these edges with anatomical connotations and others with spatial connotations. Implications for surgical treatment.
Frequency of atrial septal aneurysms in patients with cerebral ischemic events. 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. If such a mechanism is suspected, temporary balloon occlusion of the defect should permit its unmasking.
The defect must have a favorable anatomy, with adequate rims of at least 5 mm to anchor the prosthesis. After device deployment, the echocardiographer must assess the device integrity, position and stabilityresidual shunt, atrio-ventricular valve regurgitation, obstruction to systemic or venous return and pericardial effusion, in order to determine procedural success comunivacion diagnose immediate complications.
Follow up should include transthoracic echocardiography TTE the day following device deployment. 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 interauuricular the base of the aortic root.

In older patients, left diastolic ventricular dysfunction associated with elevated flling pressures is observed and may lead to secondary pulmonary hypertension.
Comparison of intracardiac echocardiography versus transesophageal echocardiography guidance for percutaneous transcatheter closure of atrial septal inetrauricular.
J Am Coll Cardiol ;6: Hoffman JI, Christianson R. 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. The diameter of the indentation can also be measured with fuoroscopy Figure 12 using calibration markers on the balloon catheter.
Canadian Cardiovascular Society Consensus Conference on the management of adults with congenital heart disease: Am J Cardiol ; Transesophageal echocardiography is also important during the procedure to guide the deployment comuncacion the device.
Nearby structures might be compromised after positioning of the occluder device.
Comunicación interauricular (para Niños)
The main advantage of this technique is its short inflation-deflation cycle, comunicacio the procedure much simpler. In most centers, the static balloon measurement technique is used. To simplify this classification we refer to Table 1.
Cathet Cardiovasc Diagn ; TEE assessment of ASD includes evaluation of the number and localization of the defect sdimensions and interajricular of the rims, direction and severity of the shunt, and the presence of possible associated defects.
