Does the 4D mini-TEE probe provide adequate image quality and improve patient tolerance compared to standard TEE probes in adults undergoing echocardiography or transcatheter interventions?
The 4D mini-TEE probe offers excellent imaging capabilities for transcatheter interventions while significantly reducing the need for general anesthesia and improving patient comfort.
May enable unsedated TEE imaging; hypothesis-generating and requires prospective validation before practice change.
Background: Transesophageal echocardiography (TEE) is a vital diagnostic tool in clinical practice, particularly in transcatheter interventions where it aids in both pre-operative planning and intra-operative guidance. Traditional TEE probes often require general anesthesia due to patient discomfort. However, the development of miniaturized TEE probes presents a promising alternative, enabling routine examinations and interventions with minimal sedation. This study evaluates the feasibility of performing a complete 2D/4D TEE protocol with the new 4D mini-TEE probe in the echocardiography department and its application in transcatheter interventions. Methods: This is a retrospective study that included 30 consecutive patients from two high-volume European hospitals (Interbalkan Medical Center, Thessaloniki, Greece, and Rennes University, France) that underwent TEE or transcatheter interventions. The new 4D mini-TEE 9VT-D probe (GE Healthcare) was utilized. The quality of the images and the tolerance of the probe were assessed in the cath lab during interventions and in the echocardiography department during routine TEE examinations. Results: Direct comparison of the 4D mini-TEE probe with the standard 6VT-D probe confirmed the excellent image quality of this new pediatric probe. Most of the patients required minimal sedation or local oropharyngeal anesthesia, with satisfactory tolerance reported. Most of the transcatheter procedures did not require general anesthesia and intubation, resulting in shorter procedural time. Both 2D and 4D imaging modalities offered adequate intra-operative guidance for transcatheter procedures. Conclusions: The 4D mini-TEE probe delivers exceptional imaging capabilities for routine examinations and transcatheter interventions without needing sedation. Its use reduces esophageal trauma and the need for general anesthesia, enhancing patient comfort and safety.

Παπαδόπουλος et al. (2024) conducted an observational in Patients undergoing TEE or transcatheter interventions (n=30). 4D mini-TEE 9VT-D probe vs. Standard 6VT-D probe was evaluated on Image quality and probe tolerance. The 4D mini-TEE probe provided excellent image quality and adequate intra-operative guidance for transcatheter interventions with minimal sedation compared to the standard 6VT-D probe.
