ASD: Improvement in Balloon

Sizing

Pitfalls of Balloon Sizing:

Oversizing of ASD (?aortic erosion)

iatrogenic enlargement of the ASD

thoracic pain

rupture of interatrial septum

ICE

Echo in Septal Closure

Transcatheter device closure has become an established treatment option for patients with ASDs.

(Chan KC, et al. Heart 1999;82:300)

TEE provides information that makes this interventional catheterization procedure easier, safer and more effective than using fluoroscopic guidance alone.

Application of real-time 3D TEE is feasible for the guidance of percutaneous transcatheter ASD and PFO

closures. During PFO closure, 3D TEE offers better spatial orientation of left atrial structures

(Balzer J, et al. Eur Heart J 2008;29:2226)

Transcatheter Closure of

Post-infarct VSD

Devices:

Amplatzer Muscular VSD occluder: waist 7 mm

Amplatzer Muscular VSD occluder post-infarction (PI): waist 10 mm (not available in US)

Patient Selection:

Exact localization of the VSD within the septum is of

paramount importance of the subsequent stability of the device

Echocardiography prior to device implantation is crucial for optimal patient selection

Kaulfersch C et al Minerva Cardioangiologica 2007;55(5):693-701

Echo in VSD closure

In initial clinical experiences using the Amplatzer Membranous VSD Occluder device to close membranous VSDs, 2D-TEE was effectively used to guide the safe and

successful performance of these complex procedures.

(Hijazi ZM, et al. Catheter Cardiovasc Interv. 2002;56:508)

In larger studies of VSD closure, 2D-TEE has been the main imaging modality used with optimal imaging for

device positioning and only limited use of ICE guidance.

LAA Thrombus

Kleeman et al. Eur J Echocardiogr 2009;10:383-8

295 pts with CHADS2 score 0 or 1, had LAA thrombus by TEE of 3% and dense smoke of 8%

11% of pts with low score had an indication for anticoagulation by TEE

Chronic Afib prevalence = 27%

Acute (<3 d) Afib prevalence = 14%
