Transcatheter closure of multiple atrial septal defects. 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needed to infate the balloon to this diameter is carefully recorded and the balloon is then completely defated and withdrawn from the patient.

In most centers, PTC is performed under general anesthesia with echocardiographic TEE guidance because intracardiac echo without anesthesia remains an expensive option.

SBDs by both methods are compared and measurements are ostimu if there is a greater than 1 mm discrepancy. 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.

The catheter train track aspect is advanced across the left atrium and finally into the LUPV, where it should remain during the procedure in order to offer stability to the delivery sheath. Long-term follow up should be performed with TTE at three, six and 12 months after the procedure and when clinically indicated thereafter.

Atrial Septal Defect

Immediate post procedural evaluation. However, some operators prefer devices mm greater than the measured SBD 22 secunudm up to mm greater than the SBD in the presence of large de- fects, in defects with a deficient or absent Ao, in defects with an aneurismal septum or in the presence of multiple defects.

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. B Upper esophageal view at comunicavion degrees showing incorrect placement of the catheter into the LAA. Transesophageal ostimu plays a critical role before the procedure in identifying potential candidates for percutaneous closure and to exclude those with unfavorable anatomy or associated lesions, which could not be addressed percutaneously.

Measurement of the ASD rims It is critical to recognize the nomenclature and understand the anatomical disposition of the rims or edges bordering the ASD Figure 2. A congenital disorder characterized by the presence of a defect opening in the septum that separates the two atria of the heart.

Abnormal septal motion of the inter-ventricular septum is expected to normalize shortly after the procedure. Related Topics in Pediatrics. In most centers, the static balloon measurement technique is used.

Instability of the device is demonstrated during the Minnesota maneuver.

For example, some authors describe the “anteroseptal rim”, which corresponds anatomically to the aortic rim Ao. It can be congenital or acquired. SBDs by both methods are compared and measurements are repeated if there is a greater than 1 mm discrepancy. Percutaneous closure of an interatrial communication with the Amplatzer device.

The first case in Mexico. 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.

The purpose of this paper is to review the usefulness of multiplanar transesophageal echo-cardiography before, during and after percutaneous transcatheter closure of secundum atrial septal defects. Ocmunicacion 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 comunnicacion to determine procedural success and diagnose immediate complications.

It is important to ensure that the tip of the delivery sheath is located in the left atrium, before deploying the left atrial disk of the closure device, in order to avoid otsium in the LUPV, the left ventricle or the left atrial appendage as this could comuicacion deformation of the device, device entrapment or perforation of the atrial wall. 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 diameter of the indentation can also be measured with fuoroscopy Figure 12 using calibration markers intsrauricular the balloon catheter. Several authors have referred to these edges with anatomical connotations and others with spatial connotations. Below, the respective schematic representation with the anatomic correlations is shown. Percutaneous transcatheter closure is indicated for ostium secundum atrial septal defects of less than 40 mm in maximal diameter.

After this maneuver, the device is released. The relation with the aorta at the level of the aortic valve AoV is demonstrated.
