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.
Transesophageal echocardiography is also ijterauricular during the procedure to guide the deployment of the device.
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. 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 Mid-esophageal short axis view of the aortic rim at 56 degrees with an adequate aortic rim 11 mm for percutaneous closure ingerauricular arrow head.
The first case in Mexico.
Percutaneous transcatheter closure is indicated for ostium secundum atrial intefauricular defects of less than 40 mm in maximal diameter. Given the fragility of the left atrial appendage, it is essential to avoid entering this thin-walled structure with catheters or the stiff guidewire, because this could cause perforation and lead to pericardial effusion.
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 the probe may help when it is not visible in the standard bi-caval view.
Quantitative analysis of the morphology of secundum-type atrial septal defects and their dynamic change using transesophageal three-dimensional echocardiography.
Failure to achieve this “Y” pattern of both disks requires device repositioning before release because this could lead to laceration of the aortic wall. TEE during device positioning, deployment, and release.

A major concern in the presence of two separate septal defects Figure 10 is the possibility of missing other supplementary defects. Mid-esophageal short axis view at 59 degrees with color Doppler ostimu the right panel demonstrating the absence of an aortic rim. In most centers, PTC is performed under general anesthesia with echocardiographic TEE guidance because intra-cardiac echo without anesthesia remains an expensive option.
A congenital disorder characterized by the presence of a defect opening in the septum that separates the two atria of the heart. Patients should address specific medical concerns with their physicians.
The relation of the device with the aorta at the level of the AoV is depicted. The size of the ASD changes during the cardiac cycle; the maximal ASD diameter must be measured at the end of ventricular systole.
Factors affecting nonsurgical closure of large secundum defects using the Amplatzer occluder. The presence of a defect opening in the septum that separates the two atria of the heart. CD is used to image fow through the ASD and the balloon is then gently pulled back, at which stage color fow on the TEE will disappear when balloon occlusion is complete.
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. 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.
Atrial Septal Defect
Comparison of intracardiac echocardiography versus transesophageal echocardiography guidance for percutaneous transcatheter closure of atrial septal defect. The Amplatzer septal occluder device is “encroaching” the aorta at the level of the aortic valve AoV. Nearby structures might be compromised after positioning of the occluder device. The presence of multiple defects of the inter-atrial septum have been reported in 7.
Mitral valve leafets might be encroached by the occluder device, producing mitral regurgitation in a defect with a defcient AV rim and, infow from interakricular SVC and RUPV might be compromised in a defect with a defcient SVC rim. Note the “Y” pattern “pacman effect”.
The comunicaciom of the indentation can also be measured with fluoroscopy Figure 12 using calibration markers on the balloon catheter. Morphologic, mechanical, sfcundum, and hemodynamic changes following transcatheter closure of atrial septal defect. Absent posteroinferior and anterosuperior atrial septal defect rims: Masked left ventricular restriction in elderly patients with atrial septal defects: Measurement of atrial septal defect size: C If during the delivery a thinner section becomes visible between these two thick regions, the device is unscrewing from the cable and is at risk of premature release Ostlum.
