Very Late Sinus of Valsalva Sequestration After Transcatheter Aortic Valve Implantation in Native Aortic Annuli [Case Report]

Ibrahim, Homam; Chaus, Adib; Staniloae, Cezar; Jilaihawi, Hasan; Vainrib, Alan; Alkhalil, Ahmad; Neuberger, Peter; Saric, Muhammad; Williams, Mathew
Coronary artery obstruction caused by sinus sequestration is well described after transcatheter aortic valve implantation in failed bioprosthetic valves, which usually occurs during or shortly after the transcatheter aortic valve implantation procedure. We report the presentation, management, and outcomes of 2 cases of very late sinus sequestration in native aortic annuli, which has not been described before to our knowledge. (Level of Difficulty: Advanced.).

Left Atrial Appendage Tilt-Up-and-Turn-Left Maneuver: A Novel Three-Dimensional Transesophageal Echocardiography Imaging Maneuver to Characterize the Left Atrial Appendage and to Improve Transcatheter Closure Guidance [Case Report]

Hayes, Dena E; Bamira, Daniel; Vainrib, Alan F; Freedberg, Robin S; Aizer, Anthony; Chinitz, Larry A; Saric, Muhamed
• Precise LAA anatomy must be established for LAA occlusion device selection. • We have developed the TUPLE maneuver, an acronym for “tilt up and turn left”. • The TUPLE maneuver facilitates LAA device selection and intraprocedural guidance.

The Double-Orifice Left Atrial Appendage: Multimodality and Virtual Transillumination Imaging [Case Report]

Rhee, David W; Aizer, Anthony; Chinitz, Larry A; Saric, Muhamed; Vainrib, Alan F
• LAA membranes are exceedingly rare with variable morphologies. • Thromboembolic risk with LAA membranes remains unknown. • Use of 3D TEE transillumination may assist in visualization and understanding.

Device-Associated Thrombus with Watchman FLX Left Atrial Appendage Closure Device: A Report of Two Cases [Case Report]

Dhaduk, Nehal; Vainrib, Alan F; Bamira, Daniel; Ro, Richard; Aizer, Anthony; Chinitz, Larry; Saric, Muhamed
• Individual cases of Watchman FLX DAT are scare in literature. • The Watchman FLX has shown lower rates of DAT than the Watchman 2.0. • Thrombus formation is still possible in rare instances with the Watchman FLX.

Transesophageal Echocardiographic Screening for Structural Heart Interventions

Ro, Richard; Bamira, Daniel; Bernard, Samuel; Vainrib, Alan; Ibrahim, Homam; Staniloae, Cezar; Williams, Mathew R; Saric, Muhamed
PURPOSE OF REVIEW/OBJECTIVE:Percutaneous structural interventions have provided patients with an effective therapeutic option, and its growth has been aided by echocardiography. We describe the vital role that transesophageal echocardiography (TEE) plays in screening patients prior to their procedure. RECENT FINDINGS/RESULTS:A multimodality imaging approach is employed by the valve team, but TEE plays a unique role in diagnosis and planning. Utilization of all TEE views and features such as biplane, 3D imaging, and multiplanar reconstruction ensures accurate assessment of the structural lesion of interest. The role of TEE remains essential in the planning of structural interventions, and these studies should be performed in a systematic and comprehensive manner.

Taking Command of 3D Stitching Artifacts: From an Annoyance to an Easy Tool for Navigating 3D Transesophageal Echocardiography

Maidman, Samuel D; Bamira, Daniel; Ro, Richard; Vainrib, Alan F; Saric, Muhamed
Despite many recent advances in three-dimensional (3D) transesophageal (TEE) imagining, the process of orienting 3D TEE images is nonintuitive and uses assumptions based on idealized anatomy. Correlating two-dimensional (2D) TEE cross-sectional images to 3D reconstructions remains an additional challenge. Here, we suggest the repurposing of the stitching artifact generated in 2-beat ECG-gated 3D TEE as a means of exactly orienting 3D images within a patient's unique anatomy. In this article, we demonstrate this application of this strategy to assess a normal mitral valve (MV), to localize scallops of mitral valve prolapse and to visualize typical left atrial appendage 2D cuts in a 3D space. By taking command of stitching artifacts, cardiac imagers can successfully navigate the complex structures of the heart for optimal, individualized echocardiographic views.

Bacterial endocarditis with AACEK (HACEK) organisms [Case Report]

Kuohn, Lindsey R; Ro, Richard; Bamira, Daniel; Vainrib, Alan; Freedberg, Robin; Galloway, Aubrey; Williams, Mathew R; Saric, Muhamed
INTRODUCTION/BACKGROUND:Gram-negative organisms of the AACEK group, formerly known as HACEK, rarely cause endocarditis. CASE SERIES/METHODS:We present three cases of bacterial endocarditis, involving native and prosthetic valves, caused by AACEK organisms. In two patients, Cardiobacterium hominis was the responsible organism, and in a third, Aggregatibacter aphrophilus was implicated. A dental source of infection was identified in two patients, and in all three patients, the presentation of endocarditis was subacute. DISCUSSION/CONCLUSIONS:This case series highlights the indolent nature of infection with the AACEK organisms. It also demonstrates the crucial role of multimodality imaging, especially transesophageal echocardiography, in the diagnosis of AACEk endocarditis of both native and prosthetic valves, and in delineating the extent of abscess in those with prosthetic valve infection.
