It is important to have a good alignment when doing the measurement of the SBD, because misalignment will produce incorrect measurements. Initial results and value of two- and three-dimensional transoesophageal echocardiography. The device and adjacent structures are evaluated 8 to rule out device 14 mal-positioning, interference with aortic, mitral, or tricuspid valvular function, caval, CS, or pulmonary venous return obstruction, and pericardial effusion.
The purpose of this paper is to review the usefulness of multiplanar transesophageal echocardiography before, during and after percutaneous transcatheter closure of secundum atrial septal defects. Catheter closure of atrial septal defects with deficient inferior vena cava rim under transesophageal echo guidance. The role of echocardiography during interventional procedures is well documented 3,4 and several techniques have been described for the guidance of PTC of ASD.
After this maneuver, the device is released.

J Am Coll Cardiol ; 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. Cathet Cardiovasc Diagn ; Transvenous closure of moderate and large secundum atrial septal defects in adults using the Amplatzer septal occluder. Transcatheter closure of multiple atrial septal defects. The presence of residual shunts should be reassessed; this could be achieved with contrast echocardiography with agitated normal saline, which opacifies the right sided cardiac chambers and may demonstrate the un-opacified jet of the left to right shunt.
Given the fragility of interaurkcular 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.
If such a mechanism is suspected, temporary balloon occlusion of the defect should permit its unmasking. 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 interauriculzr septum or vomunicacion the presence of multiple defects.
After device deployment, the echocardiographer must assess the device integrity, position and stabilityresidual shunt, atrio-ventricular adultps regurgitation, obstruction to systemic or venous return and pericardial effusion, in order to determine procedural success and diagnose immediate complications.
Device preparation for delivery is an important process of PTC and requires a meticulous approach on behalf of the interventional cardiologist Figure J Invasive Cardiol ; The defect must have a favorable anatomy, with adequate rims of at least 5 mm to anchor the prosthesis. TEE is the ideal imaging and assessment tool to evaluate and guide procedures and determine immediate procedural success, while ruling out complications.
Multiplanar transesophageal echocardiography for the evaluation and percutaneous management of ostium secundum atrial septal defects in the adult. The use of aspirin 48 hours prior the procedure and for at least six months after adultoz procedure is recommended, as well as antibiotic prophylaxis 7 for six months after the procedure.
It is critical to recognize the nomenclature and understand the anatomical disposition of the rims or edges bordering the ASD Figure 2. Failure to achieve this “Y” pattern of both disks requires device repositioning before release because this could lead to laceration of the aortic wall. Follow up The presence of residual qdultos should be reassessed; this could be achieved with contrast echocardiography with agitated normal saline, which ingerauricular the right sided cardiac chambers and may demonstrate the un-opacified jet of the left to right shunt.
Transcatheter occlusion of complex atrial septal defects. The size of the ASD changes during the cardiac cycle; the maximal ASD diameter must be measured at the end of ventricular systole. Arch Inst Cardiol Mex ; Abnormal septal motion of the inter-ventricular septum is expected to normalize shortly after the procedure.
Canadian Cardiovascular Society Consensus Conference on the management of adults with interauricu,ar heart disease: Aneurysm of the inter-atrial septum is defined as: Congenit Heart Dis ;5: The presence of multiple defects of the inter-atrial septum have been reported in 7. It is important to ensure that the tip of the delivery sheath is located in the left atrium, before deploying interauricularr left atrial disk of the closure device, in order to avoid deployment in the LUPV, the left ventricle or the left atrial appendage as this could cause deformation of the device, device entrapment or perforation of the atrial wall.
Transesophageal echocardiography plays a critical role before the procedure intdrauricular identifying potential candidates for percutaneous closure and to exclude those with unfavorable anatomy or associated lesions, which could not be addressed percutaneously. Percutaneous transcatheter closure is indicated for ostium secundum atrial septal comunicacio of less than 40 mm in maximal diameter.
For reasons of clarity, anatomic connotations comunicacioj used herein. Diagnosis and classification of atrial septal aneurysm by two-dimensional echocardiography: A thorough evaluation for presence of residual shunts is performed for future correlation. It is important to be aware of the potential long term complications such as encroachment of mitral or aortic valve leafets, impairment of fow from the pulmonary veins, reactive or hemorrhagic pericarditis, and migration or dislodgement of the device.
Sometimes the Ao is very small, or even absent Comunicxcion 7this finding makes the procedure more challenging but does not, preclude PTC of the defect.
Implications for surgical treatment. Defects up to 40 mm in diameter with firm and adequate rims have been closed successfully via PTC, avultos have multiple ASDs and those associated with atrial septal aneurysms. Measurement of atrial septal defect size: In most centers, the static balloon measurement technique is used. Afterwards, it is re-infated to the SBD volume and measured against a sizing plate.
Masked left ventricular restriction in elderly patients with atrial septal defects: Echocardiologists’ role in the deployment of the Amplatzer atrial septal occluder device in adults.
Eur Heart J ; 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 encroaches the base of the aortic root. Nearby structures might be compromised after positioning of the occluder device. A major concern in the presence of two separate septal defects Figure 10 is the possibility of missing other supplementary defects.
In these cases, it has been suggested to adulto two balloons simultaneously under TEE guidance and to exclude a possible third atrial septal defect with CD assessment. Quantitative analysis of the morphology of secundum-type atrial septal defects and their dynamic change using comunicaclon three-dimensional echocardiography.
