Transthoracic (TTE) and transesophageal (TEE) echocardiography represent the basic imaging tools for interatrial septum examination. Three dimensional (3D) TEE provides incremental information in the assessment of the interatrial septum. Further advanced echocardiography techniques using speckle tracking echocardiography are applied for sensitive volumetric and functional assessment of the heart...

FAQs
The clip applies force across the arteriotomy, bringing the vessel edges together so the opening can seal while blood continues through the vessel lumen. This balance is central to the technique: insufficient closure may allow persistent bleeding, whereas inaccurate placement or excessive interference with the vessel can contribute to vascular complications. Deployment therefore depends on controlled positioning.
Accurate positioning places the clip across the intended arteriotomy rather than an unsuitable portion of the vessel. Correct placement allows the closing force to act on the vessel edges and supports access-site hemostasis while preserving blood flow. Positioning errors can reduce sealing effectiveness or increase the likelihood of complications such as bleeding or thrombosis.
The main outcome-related considerations identified for this technique are the access vessel, the location of the arteriotomy, clip positioning, and the vessel’s response after deployment. Assessing the vessel before application helps determine whether closure can be performed appropriately. Post-deployment monitoring then helps identify persistent bleeding, thrombosis, or other vascular problems.
After arterial access has supported diagnostic angiography or an endovascular intervention, the access site may require prompt management. The delivery system is positioned at the arteriotomy, the clip is deployed to approximate the vessel edges, and the site is monitored afterward. This approach is particularly relevant when rapid restoration of access-site integrity and bleeding control is important.
The procedure begins with assessment of the access vessel and the arteriotomy created during catheter-based treatment. A delivery system then guides the clip to the intended location, where deployment brings the vessel edges together. After application, clinicians monitor the access site and vascular status for bleeding, thrombosis, or other complications.
Post-application monitoring focuses on whether the access site remains sealed and whether blood flow through the vessel is preserved. Persistent or recurrent bleeding may indicate inadequate hemostasis, while thrombosis represents a different vascular complication. Continued observation is therefore important after diagnostic angiography or endovascular intervention, especially when rapid access-site management motivated clip use.
