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.
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 Comparison of intracardiac echocardiography versus transesophageal echocardiography guidance for percutaneous transcatheter closure of atrial septal defect.
Comunicación interauricular (para Niños)
To simplify this classification we refer to Table 1. Immediate post procedural evaluation A thorough evaluation for presence of residual shunts is performed for future correlation.
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.
Device preparation for delivery is an important process of PTC and requires a meticulous approach on behalf of the interventional cardiologist Figure Congenital heart disease among liveborn children in Liverpool to Masked left ventricular restriction in elderly patients with atrial septal defects: J Am Coll Cardiol ; 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.
Overstretching of adulttos ASD should be avoided to prevent erosion related to the utilization of oversized devices. The size of the ASD changes during the cardiac cycle; the maximal ASD diameter must be measured at the end of ventricular systole. Conclusions Percutaneous closure of significant shunting associated with secundum ASD represents an attractive less-invasive alternative therapy to surgery and is being increasingly performed worldwide. J Am Coll Cardiol ;6: Current indications for ASD closure are out of the scope of this paper and can be reviewed elsewhere.
Transesophageal echocardiography multimedia manual: 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 comhnicacion un-opacified jet of the left to right shunt. Multiplanar transesophageal echocardiography for the evaluation and percutaneous management of ostium secundum atrial septal defects in the adult.
interajricular Abnormal septal motion of the inter-ventricular septum is expected to normalize shortly after the procedure. The reversal of RV volume overload has been shown as early as 3 weeks post procedure in children and 9 months in adults, 28 also systolic pulmonary artery pressure dropped to near normal levels during the following few months.
Transesophageal echocardiography is also important during the procedure to guide the deployment of the device. Special considerations In older adultoe, left diastolic ventricular dysfunction associated with elevated flling pressures is observed and may lead to secondary pulmonary hypertension.
Mitral valve leafets might be encroached by the occluder device, producing mitral regurgitation in a defect with a defcient AV rim and, comunicacioj from the SVC and RUPV might be compromised in a defect with a defcient SVC rim.
Percutaneous closure of an interatrial communication with the Amplatzer device. Morphologic, mechanical, conductive, and hemodynamic changes following transcatheter closure of atrial septal defect. Under TEE guidance, the occluder device is scanned in 2-D and with CD in several views, looking for proper positioning and residual shunts. Cathet Cardiovasc Diagn ; Closure of secundum atrial septal defects with the Amplatzer septal occluder device: Transesophageal echocardiography; Percutaneous closure; Atrial septal defect; Canada.
The main advantage of this technique is its short inflation-deflation cycle, making the procedure much simpler. This serious complication can be prevented by pushing back the structure using a second catheter.

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. 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. 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.
It is critical to recognize the nomenclature and understand the anatomical disposition of the rims or edges bordering the ASD Figure 2. It is recommended to choose a device that is the same size of the SBP to prevent oversizing and erosions.
