Absent posteroinferior and anterosuperior atrial septal defect rims: Implications for surgical treatment.

Comunicación interauricular

Br Heart J ; Hoffman JI, Christianson R. 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.

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 Received on February 1, ; Accepted on October 3, Congenital heart disease among liveborn children in Liverpool to Transcatheter closure of secundum atrial septal defects using the new self-centering amplatzer septal occluder: Measurement of atrial septal defect size: 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.

Follow up should include transthoracic echocardiography TTE the day following device deployment. The mid-esophageal bi-caval view provides an excellent view of the inter-atrial septum, allowing interrogation of the septum with CD.

The echocardiographer must confirm that both disks are fattened with good apposition, and assess residual shunting. In order to ensure stability during device delivery, the interventional cardiologist will position a supportive guidewire, through the ASD and left atrium, most often into the left upper pulmonary vein LUPV.

The potential of paradoxical embolus may be assessed by increasing right sided pressures with the Valsalva maneuver. SBDs by both methods are compared and measurements are repeated if there is a greater than 1 mm discrepancy.

Nearby structures might be compromised after positioning of the occluder device. Immediate post procedural evaluation A thorough evaluation for presence of residual shunts is performed for comunicacin correlation. Long-term follow up should be performed with TTE at three, six and 12 months after the procedure and when clinically indicated thereafter.

The first case in Mexico. Transcatheter closure of multiple atrial septal defects. Transcatheter occlusion of complex atrial septal defects. 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.

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.

J Am Soc Echocardiogr ; 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.

This serious complication can be prevented by pushing back the structure using a second catheter. 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.

When the Ao is absent, a typical “Y” pattern of the device being sandwiched around the AA should be seen Figure Frequency of atrial septal aneurysms in patients with cerebral ischemic events.

Can J Cardiol ; Special considerations In older patients, left diastolic ventricular dysfunction associated with elevated flling pressures is observed and may lead to secondary pulmonary hypertension. Multiplanar transesophageal echocardiography for the evaluation and percutaneous management of ostium secundum atrial septal defects in the adult.

For reasons of clarity, anatomic connotations are used herein. After having loaded the device in the delivery sheath, its insertion must be performed under TEE guidance.

Under TEE guidance, the occluder device is scanned in 2-D and with CD in several views, looking for proper positioning and residual shunts. TEE assessment of ASD includes evaluation of the number and localization of the defect sdimensions and adequacy of the rims, direction and severity of the shunt, and the presence of possible associated defects.

Pitfalls in diagnosing PFO: 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 cierde with an aneurismal septum or in the presence of multiple defects.

For example, some authors describe the “antero-septal rim”, which corresponds anatomically to the aortic rim Ao. Current indications for ASD closure are out of the scope of this paper and can be reviewed elsewhere. Arch Inst Cardiol Mex ; Familiarization with TEE in this context is essential for the echocardiographer involved in the modern care of patients with ASD.

Interauricullar 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.
