  • IMAGING MODALITIES Transesophageal Echocardiography The TEE probe is a flexible ultrasound gastroscope that is advanced along the esophagus and into the stomach to image the heart and great vessels. (ovid.com)
  • Mediastinal air, tubes, and surgical dressings can impede ultrasound transmission and limit the utility of TTE imaging. (ovid.com)
  • Imaging from the confines of the gastroesophageal track reduces signal attenuation and permits use of higher ultrasound frequencies, thereby providing superb spatial resolution. (radcliffecardiology.com)
  • The role of TEE has become established beyond the confines of the CV ultrasound imaging and hemodynamic laboratory, and is being used with increasing frequency in the operating room (OR), with percutaneous procedures such as closure of defects within the heart, percutaneous implantation of valves, and surgical procedures being performed in the catheterization or the electrophysiologic laboratory.

  • MitraClip
  • Real-time three-dimensional (3D) TEE has recently been used as additional imaging modality during the MitraClip procedure. (uzh.ch)
  • Imaging in MV Interventions: MitraClip and Beyond. (acc.org)
  • Transthoracic echocardiography is valuable as a screening tool for patients being considered for the MitraClip and can identify the etiology and severity of the MR. In the EVEREST II (Endovascular Valve Edge-to-Edge Repair Study II) trial, patients were also assessed with a preprocedural TEE to determine eligibility for the procedure. (acc.org)
  • METHODS
  • Aortography was the study that established the diagnosis in most cases reported before the development and widespread use of newer imaging methods. (thefreedictionary.com)
  • detection
  • Fast segmented cine gradient-echo MRI techniques provided mass depiction in all patients, while T1-weighted spin-echo imaging failed in mass detection in one patient. (springer.com)
  • structures
  • COMPARABLE TTE AND TEE VIEWS In Table 1 , 5 basic TTE views along with corresponding TEE views are listed with the structures that are imaged. (ovid.com)
  • procedure
  • This review describes the relevant role of 3D TEE imaging during the procedure, but also its limitations. (uzh.ch)
