Transcatheter aortic valve implantation (TAVI) is an effective and less invasive treatment for the increasing population of individuals with severe aortic stenosis (AS). Echocardiography is crucial in the assessment of AS patients from pre- to post-procedure. Transthoracic echocardiography (TTE) may be used to assess patient suitability for TAVI, as well as evaluate the severity of AS, the aortic valve complex, aortic valve morphology, mitral regurgitation (MR), and left ventricular function. Transesophageal echocardiography (TEE) is usually used as an intra-procedural monitoring tool to provide feedback during the procedure, to assess prosthetic valve function, and to detect complications rapidly before and after balloon aortic valvuloplasty (BAV) or transcatheter heart valve (THV) deployment...

We report the case of a 56-year-old man showing numerous cardiovascular manifestations of Listeria infection (myo-pericarditis, coronary vasospasm, intracavitary vegetations/thrombus, sinoatrial blocks). Cardiac magnetic resonance and echocardiography images provided an unexpected picture of this infection, and were relevant for the appropriate clinical management. Transthoracic and transesophageal echocardiography were useful for assessing the presence of an endocavitary mass. Tissue characterization by cardiac magnetic resonance confirmed the presence of a thrombus and revealed signs of active inflammation in the myocardial wall, pericardium and vascular pedicle...

A 70-years-old male with a history of hypertension and drug resistant paroxysmal atrial fibrillation (AF) presented to our hospital for catheter ablation to his symptomatic AF. He had no prior surgical or percutaneous procedure to close or exclude the left atrial appendage (LAA). A transesophageal echocardiography (TEE) was performed to rule out intra-cardiac thrombus prior to the ablation procedure. Although the TEE imaging at multiple acquisition angles was obtained, the LAA could not be visualized and an absence of the LAA was suspected...

Transcatheter left atrial appendage occlusion is increasingly used for stroke prevention in atrial fibrillation. The technique has proven effective and safe in randomized trials and multiple observational studies. The procedure is challenging due to the complex anatomy of the left atrial appendage; accurate cardiac imaging is essential for procedural guidance. Transesophageal echocardiography is the gold standard, but cardiac computed tomography (CT) has gained increasing interest within recent years. Cardiac CT offers high-resolution imaging allowing for preprocedural anatomic evaluation and device sizing, but may also be useful for exclusion of left atrial appendage thrombus, and follow-up assessment of residual peri-device leaks...

Left atrial appendage occlusion (LAAO) is a rapidly evolving technology. Multi-modality imaging and understanding of left atrial appendage anatomy are sure to advance. Two-dimensional and 3-dimensional transesophageal echocardiography with fluoroscopy are the mainstay for LAAO image-guided therapy. Key to successful LAAO is an understanding of the transseptal puncture, LAAO size selection for the device-specific landing zone, and postdeployment evaluation for leak and complications. With advancements in computed tomography, there may be a greater role for intracardiac echocardiographic imaging in specific types of LAAO anatomy and devices...

OBJECTIVE: Blood flow across the mitral valve during early left ventricular (LV) filling produces a 3-dimensional rotational fluid body, known as a vortex ring, that enhances LV filling efficiency. Diastolic dysfunction is common in elderly patients, but the influence of advanced age on vortex formation is unknown. The authors tested the hypothesis that advanced age is associated with a reduction in LV filling efficiency quantified using vortex formation time (VFT) in octogenarians undergoing coronary artery bypass graft (CABG) surgery...

Prosthetic valve thrombosis (PVT) is a potentially life-threatening complication associated with high morbidity and mortality. The CHA2DS2-VASc is a clinical score used to determine thromboembolism risk in non-valvular atrial fibrillation patients. Therefore; in this study, we aimed to determine predictive value of the CHA2DS2-VASc score for development of PVT in patients with mechanical prosthetic valve. This was a retrospective study included 417 consecutive patients with mechanic prosthetic valve in whom transesophageal echocardiography (TEE) was performed due to different clinical indications from January 2004 to June 2016...

AIM: Two-dimensional, transthoracic echocardiography does not account for the noncircular anatomy of the left ventricular outflow tract (LVOT) and may therefore underestimate LVOT area. Fusion of computed tomography (CT)-derived LVOT area and Doppler-derived flow data has been proposed to improve assessment of aortic valve area (AVA) and classification of aortic stenosis severity. For hemodynamic reasons, effective AVA has to be smaller than anatomic AVA. The aim of the study was to test the "fusion approach" by comparing effective CT-derived AVA with anatomic AVA from CT planimetry...

BACKGROUND: Real-time three-dimensional transesophageal echocardiography (RT3D TEE) enables better visualization of the left atrial appendage (LAA) and may be superior to real-time two-dimensional transesophageal echocardiography (RT2D TEE) for LAA occlusion (LAAO). The aim of this study was to assess inter- and intra-observer variability of RT2D TEE and RT3D TEE measurements of LAA, and to assess the accordance of RT2D TEE and RT3D TEE with appropriate occluder selection. METHODS: Transesophageal echocardiography was performed in 40 patients during LAAO...

This report illustrates a case of a 42-year-old male with a history of intravenous drug abuse who presented with septic shock. Diagnostic studies, including a transthoracic echocardiogram, chest computed tomography angiography, transesophageal echocardiogram, and blood cultures ultimately revealed Serratia marcescens pulmonic valve infective endocarditis that was treated with intravenous antibiotics. In addition to the rare form of endocarditis and bacterium involved, this case brings into awareness the dynamic nature of the hospital course that requires vigilance in responding to hypotensive episodes for consideration of pulmonary embolism...
