Introducing the Philips X11-4t mini 3D TEE
Innovations in cardiovascular ultrasound technology are enabling better access to care and improved outcomes for a greater number of people, from tiny pediatric patients to the frail, elderly population. The X11-4t mini 3D TEE transducer is one example of such innovation, with a tip of only 11 millimeters that makes it suitable for patients as small as five kilograms or patients with exceedingly narrow anatomical spaces. Providing outstanding image quality and multiple imaging options, the X11-4t mini 3D TEE transducer easily integrates into existing workflows.
At-a-glance:
- The evolution of cardiovascular ultrasound technology is a driving force behind continued improvements in patient care
- Patients with congenital heart disease and structural heart issues both benefit from 3D ultrasound of complex anatomies and potential decreased sedation
- The X11-4t mini 3D TEE transducer fulfills a critical need by accommodating small pediatric patients and frail, elderly adults – and everyone in between
The evolution of cardiovascular ultrasound technology is a driving force behind continued improvements in patient care. Transesophageal echocardiogram (TEE) offers advanced diagnostic options, due to its minimally invasive nature, cost-effectiveness and versatility. The Philips X11-4t mini 3D TEE transducer accommodates a range of patients in need of TEE, from pediatric to older, more frail adults.
Appropriate for patients as small as 5 kg
Echocardiographic improvements are intended to provide higher accuracy with less risk in both diagnosis and treatment. Pediatric cases, particularly those concerning congenital heart disease, represent an especially significant treatment gap, because until recently, TEE was unavailable to patients who weigh less than 25 kg.
Interventional imaging, including TEE, is absolutely critical for us. In our practice, the vast majority of the most complex procedures are undertaken in the first two years of life.

Decreased need for general anesthesia benefits frail patients
On the other end of the spectrum, the growth in tricuspid valve procedures is indicative of an increase in structural heart issues in an aging population. These patients may be frail and more likely to respond negatively to prolonged intubation and general anesthesia.
The X11-4t may contribute to lower levels of sedation in some procedures and thus better workflow. I’ve used it on 79 patients to date, and I’ve been able to acquire diagnostic level quality on all my patients from 50 kilograms to 150 kilograms.

In both these cases and for everyone in-between, the advent of the X11-4t, a mini 3D TEE transducer that features a small tip that fits into narrow spaces, is improving diagnostic and treatment accuracy. The transducer’s insertion tube features four-way articulation to allow for better imaging of the heart from multiple angles, including gastric views, so clinicians can accurately diagnose patients with complex conditions. The small, pill-shaped tip helps to minimize intubation risks among pediatric or frail, older patients. Designed to fit within existing workflows, the X11-4t is compatible with EchoNavigator and VeriSight Pro 3D ICE Catheter, as well as the AI-driven 3D Auto Tricuspid Valve Quantification algorithm.*
