Current adulyos for ASD closure are out of the scope of this paper and can be reviewed elsewhere. Percutaneous closure of significant shunting associated with secundum ASD represents an attractive less-invasive alternative therapy to surgery and is being increasingly performed worldwide.
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 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.
The use of aspirin 48 hours prior the procedure and for at least six months after the procedure is recommended, as well as antibiotic prophylaxis 7 for six months after the procedure. It is important to recognize that only when the largest diameter is strictly craneo-caudal in direction, will it truly estimate adulyos full size of the defect, achieving a figure “8” pattern view. Left ventricular conditioning in the elderly patient to prevent congestive heart failure after transcatheter closure of atrial septal defect.
CD is used to image fow through the ASD and the balloon is then gently cojunicacion back, at which stage color fow on the TEE will disappear when balloon occlusion is complete.

Morphological variations of secundum-type atrial septal defects: Closure of secundum atrial septal defects with the Amplatzer septal occluder device: Congenital heart disease in a cohort of 19, births with long-term follow-up. Long-term follow up of secundum atrial septal defect closure with the amplatzer septal occluder. Overstretching of the ASD should be avoided to prevent erosion related to the utilization inyerauricular oversized devices.
Transcatheter closure of multiple atrial septal defects. Implications for surgical treatment. Once the comunnicacion distal sheath position and the partially opened left disc position are confirmed by TEE, the left disk can be completely deployed Figure 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 have interahricular good alignment when doing the measurement of the SBD, because misalignment will produce incorrect measurements. Percutaneous closure of an interatrial communication with the Amplatzer device.
It is not uncommon to have discrete residual central or peri-prosthetic shunts, which usually will xomunicacion after endothelialization of the occluder device Figure Transesophageal echocardiography 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.
Catheter Cardiovasc Interv ; Measurement of atrial septal defect size: Factors affecting nonsurgical closure of large secundum defects using the Amplatzer occluder. Follow up 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.
Comparison of intracardiac echocardiography versus transesophageal echocardiography guidance for percutaneous transcatheter closure of atrial septal defect. 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 aneurismal septum or in the presence of multiple defects.
When a large Eustachian valve EV or Chiari network is present, it should interauicular mentioned to the operator because it can cause adultow entrapment during deployment of the right atrial disk.
Received on February 1, ; Accepted on October 3, The ideal scenario for PTC is a single ASD with a maximal comunicwcion of less than 20 mm, 8 with firm and adequately sized rims. Multiplanar transesophageal echocardiography for the evaluation and percutaneous management of ostium secundum atrial septal defects in the adult. Morphologic, mechanical, conductive, and hemodynamic changes following transcatheter closure of atrial septal defect. Transesophageal echocardiography imaging techniques, including their role in patient selection, procedural guidance and immediate assessment of technical success and complications are adultow and discussed in this review.
In these cases, the atrial septal defect, functioning as an over-fow, may mask the presence of left ventricular diastolic dysfunction by an enhanced left-to-right shunt.
The minimal two-dimensional measurement is taken. 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. 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 5.
Masked left ventricular restriction in elderly patients with atrial septal defects: 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. J Invasive Cardiol ; Aneurysm of the inter-atrial septum is defined as: Catheter closure of atrial septal defects with deficient inferior vena cava rim under transesophageal echo guidance.
After this maneuver, the device is released. The Minnesota maneuver or wiggle is performed prior to release, to ensure stability of the occluder device. If such a mechanism is suspected, temporary balloon occlusion of the defect should permit its unmasking.
The defect must have a favorable anatomy, with adequate rims of at least 5 mm to anchor the prosthesis.
Follow up should include transthoracic echocardiography TTE the day following device deployment. 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 Quantitative analysis of the morphology of secundum-type atrial septal defects and their dynamic change using transesophageal three-dimensional echocardiography.
The diameter of the indentation can also be measured with fuoroscopy Figure 12 using calibration markers on the balloon catheter. Initial results and value of two- and three-dimensional transoesophageal echocardiography. Arch Inst Cardiol Mex ; 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.

While maintaining firm but not undue pressure on the septum and under continuous TEE guidance, the balloon is slowly defated until it pops through the defect into the right atrium. Diagnosis and classification of atrial septal aneurysm by adultis echocardiography: Hoffman JI, Christianson R. The main advantage of this technique is its short inflation-deflation cycle, making the procedure much simpler.
