PURPOSE: There are no formal radiologic criteria to stratify patients for transcanal (TEES) or transmastoid endoscopic ear surgery for resection of cholesteatoma. We aim to determine 1) whether standard preoperative computed tomography (CT) findings are associated with the need for conversion to a transmastoid approach and 2) the amount of time added for conversion from TEES to transmastoid techniques. MATERIALS AND METHODS: Retrospective chart review of consecutive pediatric and adult cases of TEES for primary cholesteatoma from 2013 through 2015 (n=52)...

Transesophageal echocardiography (TEE) was first used routinely in the operating rooms in the 1980s to facilitate surgical decision-making. Since then, TEE has evolved from the standard two-dimensional (2D) exam to include focused real-time three-dimensional (RT-3D) imaging both inside and outside the operating rooms. Improved spatial and temporal resolution due to technological advances has expedited surgical interventions in diseased valves. 3D imaging has also emerged as a crucial adjunct in percutaneous interventions for structural heart disease...

The point-of-care ultrasound exam has become an essential tool for hemodynamic monitoring and resuscitation in the trauma bay as well as the intensive care unit. Transthoracic ultrasound provides a dynamic assessment of cardiac function, volume status, and fluid responsiveness that offers potential advantage over traditional methods of hemodynamic monitoring. More recently, a focused transthoracic echocardiography exam was described to improve immediate resuscitation of severely injured patients in the trauma bay...

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%)...

The optimization and maintenance of mean arterial blood pressure (MAP) and the general avoidance of systemic hypotension for the first 5-7 days following acute traumatic spinal cord injury (tSCI) is considered to be important for minimizing secondary spinal cord ischemic damage. The characterization of hemodynamic parameters in the immediate post-injury stage prior to admission to a specialized spine unit has not been previously reported. Here we describe the blood pressure management of 40 acute tSCI patients in the early post-injury phases of care prior to their arrival in a specialized spinal injury high dependency unit (HDU), intensive care unit (ICU), or operating room (OR)...

STUDY OBJECTIVE: Several authors have reported rare, but severe, complications associated with the length of the intravascular guidewire during central venous catheter placement, as the wire tip can cause cardiac arrhythmia or perforation or become trapped within the vessel. Although one report investigated the optimal guidewire length using fluoroscopy, few reports have precisely measured guidewire position using transesophageal echocardiography (TEE). Here, we investigated the appropriate intravascular length of a guidewire for right internal jugular vein approach using TEE during cardiac surgery...

Transoesophageal echocardiography (TOE) is used in the perioperative arena to monitor patients during life-threatening emergencies, cardiac and high-risk non-cardiac surgeries. It provides qualitative and quantitative information on valvular and ventricular functions, and dynamic cardiac anatomy can be displayed with a physiological perspective. This technology has evolved from two-dimensional (2D) to the ready availability of real-time three-dimensional (RT-3D) imaging in the operating rooms. Enhanced spatial and temporal resolutions with 3D imaging have most significantly impacted the quality of intraoperative surgical valve repair and replacement decisions...

Transcanal endoscopic ear surgery (TEES) is being increasingly used in chronic ear disease for cholesteatoma removal and middle ear reconstruction, reducing the need for a postauricular incision and mastoidectomy. However, TEES is a challenging technique even for the most experienced otologist, requiring one-handed dissection using angled instrumentation. We have therefore developed a high-fidelity dissection model incorporating key aspects of TEES and cholesteatoma removal to facilitate the acquisition of these skills...

Stanford type A aortic dissections often present to the hospital requiring emergent surgical intervention. Initial diagnosis is usually made by computed tomography; however transesophageal echocardiography (TEE) can further characterize aortic dissections with specific advantages: It may be performed on an unstable patient, it can be used intra-operatively, and it has the ability to provide continuous real-time information. Three-dimensional (3D) TEE has become more accessible over recent years allowing it to serve as an additional tool in the operating room...
