Transesophageal echocardiography multimedia manual: In these cases, it has been suggested to infate two balloons simultaneously under TEE guidance and to exclude a possible third atrial septal defect with CD assessment. The first case in Mexico.
Frequency of atrial septal aneurysms in patients with cerebral ischemic events. In summary, the baseline TEE must meet the criteria described in Table 2 in order for the patient to be eligible for percutaneous closure.
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. Implications for surgical treatment. J Invasive Cardiol ; Percutaneous closure of secundum atrial septal defect in adults a single center experience with the amplatzer septal occluder. 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 The potential of paradoxical embolus may be assessed by increasing right sided pressures with the Valsalva maneuver.
For reasons of clarity, anatomic connotations are used herein. Quantitative analysis of the morphology of secundum-type atrial septal defects and their dynamic change using transesophageal three-dimensional echocardiography.
Device preparation for delivery is an important process of PTC and requires a meticulous approach on behalf of the interventional cardiologist Figure Transcatheter occlusion of complex atrial septal defects.
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. Diagnosis and classification of atrial septal aneurysm by two-dimensional echocardiography: The size of the ASD changes during the cardiac cycle; the maximal ASD diameter must be measured at the end of ventricular systole.
Familiarization with TEE in this context is essential for the echocardiographer involved in the modern care of patients with ASD.
Abnormal septal motion of the inter-ventricular septum is expected to normalize shortly after the procedure. 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 Afterwards, it is re-infated to the SBD volume and measured against a sizing plate.
TEE assessment of ASD includes evaluation of the number and localization of the defect scominicacion and adequacy of the rims, direction and severity of the shunt, and the presence of possible associated defects.
TEE is the ideal imaging and assessment tool to se and guide procedures and determine counicacion procedural success, while ruling out complications. 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 and diagnose immediate complications. This serious complication can be prevented by pushing back the structure using a second catheter.

Initial results and value of two- and three-dimensional transoesophageal echocardiography. Transesophageal echocardiography is also important during the procedure to guide the deployment of the device. Overstretching of the ASD should be avoided to prevent erosion related to the utilization of oversized devices.
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 diffcult to visualize and measure, and retrofexion of cmunicacion probe may help when it is not visible in the standard bi-caval view.
Eur Heart J ; Morphologic, mechanical, conductive, and hemodynamic changes following transcatheter closure of atrial septal defect.
The use of aspirin 48 hours prior the procedure and for at least six months after the procedure is recommended, as well as antibiotic cietre 7 for six months after the procedure. The amount of contrast needed to infate the balloon to this diameter is carefully recorded and the balloon is then completely defated and withdrawn from the patient. Current indications for ASD closure are out of the scope of this paper and can be reviewed elsewhere.
The presence of multiple defects of the inter-atrial septum have been reported in 7. It is important to be aware of the potential long term complications such as encroachment of onterauricular or aortic valve leafets, impairment of fow from the pulmonary veins, reactive or hemorrhagic pericarditis, and migration or dislodgement of the device.
It is important to have a good alignment when doing the measurement of the SBD, because misalignment will produce incorrect measurements. The echocardiographer must confirm that both disks are fattened with good apposition, and assess residual shunting.

Long-term follow up of secundum atrial septal defect closure with the amplatzer septal occluder. After this ee, the device is released. SBDs by both methods are compared and measurements are repeated if there is a greater than 1 mm discrepancy. Follow up should include transthoracic echocardiography TTE the day clmunicacion device deployment.
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.
