Once the correct distal sheath position and the partially re left disc position are confirmed by TEE, the left disk can be completely deployed Figure When a large Eustachian valve EV or Chiari network is present, it should be mentioned to the operator because it can cause device entrapment during deployment of the right atrial disk. Long-term follow up of secundum atrial septal defect closure with the amplatzer septal occluder.

Hoffman JI, Christianson R. Device preparation for delivery is an important process of PTC and requires a meticulous approach on behalf of the interventional cardiologist Figure Percutaneous closure of an interatrial communication with the Amplatzer device. Multiplanar transesophageal echocardiography for the evaluation and percutaneous management of ostium secundum atrial septal defects in the adult.

The main advantage of this technique is its short inflation-deflation cycle, making the procedure much simpler. The presence of multiple defects of the inter-atrial septum have been reported in 7.

Catheter closure of atrial septal defects with deficient inferior vena cava rim under transesophageal echo guidance.

When resistance of the septum is encountered and TEE confirms good apposition of the LA disk with the rims of the ASD, the right atrial disk of the prosthesis is opened inside the RA, allowing the prosthesis to grasp the rims of the ASD between its two disks Figure 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.

It is important to recognize that only when the largest diameter is strictly craneo-caudal in direction, will it truly estimate the full size of the defect, achieving a figure “8” pattern view. 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. Eur Heart J ; 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.

TEE is the ideal imaging and assessment tool to evaluate and guide procedures and determine immediate procedural success, while ruling out innterauricular. 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. Br Heart J ; J Am Coll Cardiol ; Long-term follow up should be comunicadion with TTE at three, six and 12 months after the procedure and when clinically indicated thereafter.

Special considerations In older patients, left diastolic ventricular dysfunction associated with elevated flling pressures is observed and may lead to secondary pulmonary hypertension. 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 comunicacuon upper-esophageal level Figure 5.

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.

Familiarization with TEE in this context is essential for the echocardiographer involved in the modern care of patients with ASD.

For example, some authors describe the “antero-septal rim”, which corresponds anatomically to the aortic rim Ao. Transesophageal echocardiography multimedia manual: J Invasive Cardiol ; Nearby structures might be compromised after positioning of the occluder device.

Transcatheter closure of secundum atrial septal defects using the new self-centering amplatzer septal occluder: 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. Follow up should include transthoracic echocardiography TTE the day following device deployment.

The ideal scenario for PTC is a single ASD with a maximal diameter of less than 20 mm, 8 with firm and adequately sized rims. Arch Inst Cardiol Mex ; 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.

Percutaneous transcatheter closure is indicated for ostium secundum atrial septal defects of less than 40 mm in maximal diameter.

The echocardiographer must confirm that both disks are fattened with good apposition, and assess residual shunting.
