The first case in Mexico. Transcatheter closure of multiple atrial septal defects. Congenital heart disease among liveborn children in Liverpool to A Before the release of the device. Below, the schematic representation of the same view is shown.

Morphologic, mechanical, conductive, and hemodynamic changes following transcatheter closure of atrial septal defect. The comuniacion must have a favorable anatomy, with adequate rims of at least 5 mm to anchor the prosthesis.

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. The Minnesota maneuver or wiggle is performed prior to release, to ensure stability of the occluder device. Back Links pages that link to this page. Mid-esophageal short axis view.

References Saenz Am Fam Physician 59 7: Below, the schematic representation of the same view. 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.

Percutaneous transcatheter closure is indicated for ostium secundum atrial septal defects of less than 40 mm in maximal diameter. CD is used to image flow through the ASD and the balloon is then gently pulled back, at which stage color flow interaudicular the TEE will disappear when balloon occlusion is complete.

Overstretching of the ASD should be avoided to prevent erosion related to the utilization of oversized devices. Device preparation for delivery is an important process of PTC and requires a meticulous approach on behalf of the interventional cardiologist Figure Eur Heart J ; Long-term follow up should be performed with TTE at three, six and 12 months after the procedure and when clinically indicated thereafter.


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 communicacion the device.

Thereafter the device is pulled toward secumdum RA, so that its superior portion catches the superior aspect of the ASD 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 Figure The main advantage of this technique is its short inflation-deflation cycle, making the procedure much simpler.

It is important to have a good alignment when doing the measurement of the SBD, because misalignment will produce incorrect measurements.

Comparison of intracardiac echocardiography versus transesophageal echocardiography guidance for percutaneous transcatheter closure of atrial septal defect. If such a mechanism is suspected, temporary balloon occlusion of the defect should permit its unmasking.

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

To improve our services and products, we use “cookies” own or third parties authorized to show advertising related to client preferences through the analyses of navigation customer behavior. Quantitative analysis of the morphology of secundum-type atrial septal defects and their dynamic change using transesophageal three-dimensional echocardiography. SBDs by both methods are compared and measurements are repeated if there is a greater than 1 mm discrepancy.

The SBD is represented by the white doubleheaded arrow. Transesophageal echocardiography; Percutaneous closure; Atrial septal defect; Canada. The size of the ASD changes during the cardiac cycle; the maximal ASD diameter must be measured at the end of ventricular systole.

The potential of paradoxical embolus may be assessed by increasing right sided pressures with the Valsalva maneuver. Familiarization with TEE in this context is essential for the echocardiographer involved in the modern care of ostiu, with ASD. A thorough evaluation for presence of residual shunts is performed for future correlation.


Current indications for ASD closure are out ostihm the scope of this paper and can be reviewed elsewhere. Frequency of atrial septal aneurysms in patients with cerebral ischemic events.

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. This serious complication can be prevented by pushing back the structure using a second catheter. The main advantage of this technique is integauricular short inflation-deflation cycle, making the procedure much simpler.

Atrial Septal Defect

Diagnosis and classification of atrial septal aneurysm by two-dimensional echocardiography: Once the correct distal sheath position and the partially interauricu,ar left disc position are confirmed by TEE, the left disk can be completely deployed Figure A major concern in the presence of two separate septal defects Figure 10 is the possibility of missing other supplementary defects.

Received on February 1, ; accepted on October 3, 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 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 a defcient SVC rim.

After having loaded the device in the delivery sheath, its insertion must be performed under TEE guidance. The left atrial disk of the device LAD is pulled towards the RA white arrow so that it encroaches comunicacin on the aortic rim.

The amount of contrast needed to inflate the balloon to this diameter is comuniaccion recorded and the balloon is then completely deflated and withdrawn from comnuicacion patient.
