Tricuspid annular geometry: a three-dimensional transesophageal echocardiographic study.
To demonstrate the clinical feasibility of accurately measuring tricuspid annular area by 3-dimensional (3D) transesophageal echocardiography (TEE) and to assess the geometric differences based on the presence of tricuspid regurgitation (TR). Also, the shape of the tricuspid annulus was compared with previous descriptions in the literature. ⋯ Three-dimensional TEE can be used to measure the tricuspid annular area in a clinically feasible fashion, with an eccentric dilation seen in patients with TR. The tricuspid annulus shape is complex, with annular high and low points, and annular area calculation based on linear measurements significantly overestimates 3D planimetered area.

Hemodynamic pressure waveform analysis in predicting fluid responsiveness.
To assess the usefulness of central venous pressure (CVP), diastolic right ventricular pressure, and pulmonary capillary wedge pressure (PCWP) waveform analysis in predicting fluid responsiveness. ⋯ The a/v ratio measured on the PCWP tracing is a predictor of fluid responsiveness in patients with preserved left ventricular function undergoing coronary artery bypass grafting.

Episodic monoplane transesophageal echocardiography impacts postoperative management of the cardiac surgery patient.
A new slender, flexible, and miniaturized disposable monoplane transesophageal TEE probe has been approved for episodic hemodynamic transesophageal echocardiographic monitoring. The authors hypothesized that episodic monoplane TEE with a limited examination would help guide the postoperative management of high-risk cardiac surgery patients. ⋯ The authors demonstrated the ability of episodic monoplane TEE to identify discordance between hemodynamic monitoring to better define clinical scenarios in unstable cardiac surgery patients. For these challenging patients, limited episodic TEE assessment has become a cornerstone of ICU care in this institution.

The use of TEE simulation in teaching basic echocardiography skills to senior anesthesiology residents.
The authors evaluated the educational benefits of using a first-generation HeartWorks simulator to teach senior anesthesiology residents basic echocardiography skills. ⋯ Virtual reality TEE simulation technology was endorsed strongly by residents, produced a statistically significant improvement in knowledge of normal echocardiographic anatomy, and could be effective for teaching basic echocardiography to anesthesiology residents.
