Mitral annuloplasty ring thrombosis is an extremely infrequent pathology, for which no evidence-based antithrombotic management has yet been described. Herein is presented a case of heterozygous Factor V Leiden (FVL) and hyperhomocysteinemia with homozygous methylenetetrahydrofolate reductase (MTHFR) mutations that caused early thrombosis of the mitral annuloplasty ring. The clinical management and antithrombotic treatment of the patient, and the implications of hyperhomocysteinemia, are discussed. Video 1: Mobile 9-mm thrombus of mitral annuloplasty ring on two-dimensional (2D) transesophageal echocardiography...

Despite its proven superiority over two-dimensional transthoracic echocardiography (2DTTE) for left ventricular (LV) volumes and ejection fraction, clinical use of 3DTTE remains very limited in the acute setting. 3DTTE may have significant clinical advantages in the assessment of acute heart failure. Further exploration of 3DTTE utilization may help in more precise assessment of the regional wall-motion abnormalities, early identification of acute ischemic from nonischemic LV dysfunction with a more precise approach to the AHF management...

Left atrial appendage aneurysm (LAA AN) is a rare disease entity, which can be congenital or acquired in nature. We report an adult patient with LAA AN presenting with anginal chest pain in whom live/real time three-dimensional transthoracic echocardiography (3DTTE) provided incremental value over the two-dimensional (2D) technique in providing a more comprehensive assessment of the lesion. A literature review of the salient features of LAA AN is also provided in a tabular form.

BACKGROUND: Functional impairment of the aorta is a recognized complication of aortic and aortic valve disease. Aortic strain measurement provides effective quantification of mechanical aortic function, and 3-dimenional (3D) approaches may be desirable for serial evaluation. Computerized tomographic angiography (CTA) is routinely performed for various clinical indications, and offers the unique potential to study 3D aortic deformation. We sought to investigate the feasibility of performing 3D aortic strain analysis in a candidate population of patients undergoing transcatheter aortic valve replacement (TAVR)...

We report three-dimensional imaging of a rare finding of Ebstein's anomaly of the tricuspid valve in a patient with hypoplastic left heart syndrome, which has been previously reported only by two-dimensional echocardiography. A fetal echocardiogram was performed at 19 weeks that showed a moderately hypoplastic left ventricle, severely hypoplastic mitral valve, a severely hypoplastic aortic valve, and a dysplastic tricuspid valve. Post Caesarean delivery at 40 weeks of gestation, a transthoracic echocardiogram confirmed the findings seen on the fetal echocardiogram...

The right atrium (RA) is the most under-evaluated heart chamber in the clinical practice. Three-dimensional (3D) speckle-tracking echocardiography (STE) merges the benefits of 3D echocardiography and STE: volumetric and strain assessment of the RA can be performed at the same time from the same digitally acquired 3D echocardiographic dataset with a special equipment using a virtual 3D model of the RA. A diagnostic focused study is under way at the Second Department of Medicine and Cardiology Center, University of Szeged, Hungary to assess 3D-STE-derived RA variables in different patient populations, which serves as a substudy of Motion Analysis of the heart and Great vessels bY three-dimensionAl speckle-tRacking echocardiography in Pathological cases (MAGYAR-Path) Study...

Three-dimensional transesophageal echocardiography (TEE) provides real-time soft tissue information, but its use is hampered by its limited field of view. The mosaicing of multiple TEE views makes it possible to visualize a large structure, like the left atrium, in a single volume. To this end, an automatic registration method is required. Similarly to atlas-based segmentation approaches, atlas-based mosaicing (ABM) uses a full volume atlas set to moderate the onerous registration of the individual TEE views...

PURPOSE: Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure in which a prosthetic heart valve is placed and expanded within a defective aortic valve. The device placement is commonly performed using two-dimensional fluoroscopic imaging. Within this work, we propose a novel technique to track the motion and deformation of the prosthetic valve in three dimensions based on biplane fluoroscopic image sequences. METHODS: The tracking approach uses a parameterized point cloud model of the valve stent which can undergo rigid 3D transformation and different modes of expansion...
