BACKGROUND: 2D-transesophageal echocardiography (TEE) is routinely performed to guide percutaneous ASD closure in children. We aimed to assess whether two-dimensional (2D)-transthoracic echocardiography (TTE) is a safe alternative for assessment and guidance of atrial septal defect (ASD) closure in unselected children. METHODS: We performed a retrospective single-center study including 389 consecutive children aged less than 15-year-old who underwent percutaneous ASD closure under 2D-TEE (1998-2005, n=133) or 2D-TTE (2005-2014, n=256)...

A 39-year-old woman underwent uneventful percutaneous occlusion of an ostium secundum atrial septal defect (ASD) with a 22 mm Ultrasept ASD Occluder(®). Transesophageal echocardiography (TEE) performed two years after implantation revealed a de novo residual left-to-right shunt through the correctly implanted device. Three-dimensional transesophageal echocardiography (3D TEE) further clarified this finding by showing a perforation of the device membrane coating. The patient underwent transcatheter closure of the residual shunt with a 20 mm Ultrasept PFO(®) device...

Advanced imaging modalities are becoming more widely available in veterinary cardiology, including the use of transesophageal echocardiography (TEE) during occlusion of patent ductus arteriosus (PDA) in dogs. The dog in this report had a complex history of attempted ligation and a large PDA that initially precluded device placement thereby limiting the options for PDA closure. Following a second thoracotomy and partial ligation, the morphology of the PDA was altered and device occlusion was an option. Angiographic assessment of the PDA was limited by the presence of hemoclips, and the direction of ductal flow related to the change in anatomy following ligature placement...

BACKGROUND: The anatomy of septal defects can be complex and morphologically unpredictable. Balloon sizing of such defects may not be feasible, and an appropriately sized commercial occluder may not be available. Therefore, percutaneous transcatheter closure of such defects can be challenging because of an increased risk of complications. In this study, we have described the efficacy and safety of transcatheter closure of complex septal defects using Amplatzer cribriform occluder devices, assessed by real time three-dimensional (RT 3D) color Doppler transesophageal echocardiography (TEE)...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is increasingly being performed in cardiac catheterization laboratories using transthoracic echocardiography (TTE) to guide valve deployment. The risk of paravalvular regurgitation (PVR) remains a concern. METHODS: We retrospectively reviewed 454 consecutive patients (mean age, 82 ± 8; 58% male) who underwent transfemoral TAVR at Emory Healthcare from 2007 to 2014. Two hundred thirty-four patients underwent TAVR in the cardiac catheterization laboratory with TTE guidance (TTE-TAVR; mean Society of Thoracic Surgeons score, 10%), while 220 patients underwent the procedure in the hybrid operating room with transesophageal echocardiography (TEE) guidance (TEE-TAVR; mean Society of Thoracic Surgeons score, 11%)...

A 68 year-old man with a severe ischemic cardiomyopathy underwent left ventricular assist device (LVAD) implantation (Heart Mate II device) for destination therapy. He presented 49 months following LVAD implant with worsening heart failure symptoms and new severe aortic regurgitation. Given high risk for both surgical and transcatheter aortic valve replacement, he was admitted for transcatheter closure of the aortic valve under transesophageal echocardiographic (TEE) guidance. TEE imaging revealed severe aortic regurgitation (see Figure 1A and 1B, and multimedia files 1 and 2)...

Aims: The transseptal approach is used for left atrial access during the ablation of atrial fibrillation (AF) and other left-sided arrhythmia substrates. Transseptal puncture (TP) is commonly performed with fluoroscopic guidance, contrast injection, and pressure monitoring. In many centres, additional techniques [intracardiac echocardiography (ICE), transoesophageal echocardiography (TEE), radiofrequency needle] are used to facilitate TP but its use adds costs. In this retrospective study, we studied the safety and complication rate when TP was routinely done with fluoroscopic guidance, contrast injection, and pressure monitoring using ICE or TEE only in selected cases...

Gilbert's syndrome (GS) is an autosomal inherited disorder characterized by relative deficiency of glucuronyl transferase and poor uptake of unconjugated bilirubin by hepatocytes. Cardiac surgery on cardiopulmonary bypass (CPB) in these patients triggers further hepatic dysfunction. Transesophageal echocardiography (TEE) and Doppler assessment of hepatic vein help in assessing hepatic blood flow (HBF) during cardiac surgery. Here, we discuss anesthetic management and role of TEE in maintaining HBF perioperatively in a 25-year-old male patient with GS undergoing double valve replacement with tricuspid valve plasty...

The porcine model is a commonly used animal model in cardiovascular research. Along with new innovative operative techniques, choice of the optimal imaging technique is crucial. Transesophageal echocardiography (TEE) is a reliable imaging tool is highly important in a large number of experimental evaluations. But so far, TEE data for swine are limited, and few standard values have been established for the porcine model. The experience and baseline results for TEE in 45 swine are presented in this study. A full TEE examination was conducted in 45 German landrace or German large white swine, with an average body weight of 49 ± 3 kg, before experimental off-pump mitral valved stent implantation...

BACKGROUND: Balloon aortic valvuloplasty (BAV) is resurging as a bridge treatment in patients with severe aortic stenosis (AS) with a dissemination of transcatheter aortic valve implantation. However, the significantly high periprocedural mortality and complication rates still limit the indications of BAV. Further efforts are needed to improve the safety and efficacy of BAV.Methods and Results:We retrospectively investigated the safety and efficacy of simultaneous biplane mode of 3-dimensional transesophageal echocardiography (biplane-TEE) guided antegrade transseptal multiple-inflation BAV, with gradual upsizing of the balloon, by enrolling 20 consecutive AS patients who underwent BAV...

Left atrial appendage (LAA) closure is a new treatment option for the prevention of stroke in patients with nonvalvular atrial fibrillation (AF). Conventional 2-dimensional transesophageal echocardiography (2D TEE) has some limitations in the imaging assessment of LAA closure. Real-time 3-dimensional transesophageal echocardiography (RT-3D TEE) allows for detailed morphologic assessment of the LAA. In this study, we aim to determine the clinical values of RT-3D TEE in the periprocedure of LAA closure.Thirty-eight persistent or paroxysmal AF patients with indications for LAA closure were enrolled in this study...

BACKGROUND: Computed tomography angiography (CTA) is the test of choice for pre-procedure imaging of transcatheter aortic valve replacement (TAVR) candidates. The iodinated contrast required, however, increases the risk of renal dysfunction in patients with pre-existing renal failure. Ferumoxytol is a magnetic resonance imaging (MRI) contrast agent that can be used with renal failure. Its long vascular resonance time allows gated MRA sequences that approach CTA in image quality. We present respiratory and cardiac gated MRA enabled by ferumoxytol that can be post-processed in an analogous fashion to CTA...

Transesophageal echocardiography (TEE) is a promising imaging modality used to guide cardiac interventions, such as catheter ablation for the treatment of cardiac arrhythmias. These procedures rely on good visualization of the left atrium and pulmonary veins. To visualize these structures in a single volume, the acquisition, registration and fusion of multiple TEE views of the left atrium are required. We introduce atlas-based mosaicing as a method for the registration of images that are acquired according to a standardized protocol...
