The Problem We Don’t Talk About Enough

In resuscitation, we rely on TTE (POCUS)—until it fails.

And it does fail:

• Obesity

• Mechanical ventilation

• Ongoing CPR

• Chest trauma / emphysema

• Dressings, drains, defibrillator pads

At the exact moment when physiology is collapsing, our window disappears.

This is where Resuscitative TEE emerges—not as an adjunct, but as a shift in how we see critically ill patients.

What Is Resuscitative TEE?

Resuscitative TEE is:

A focused, goal-directed, point-of-care transesophageal echocardiographic exam used during cardiac arrest, shock, and critical illness to guide real-time management (Teran et al., 2025).

It evolved from:

• Rescue TEE (Shillcutt et al., 2012)

• Critical care TEE (Mayo et al., 2015)

But today, it represents a distinct resuscitation tool.

Why TEE? — The Physiological Edge

TEE works where TTE fails because:

• Esophagus = direct acoustic window to heart

• No lung or chest wall interference

• Continuous imaging during CPR

👉 Especially valuable when TTE windows are limited (Teran et al., 2025; Torre & Pirri, 2025; Prager et al., 2022).

This allows:

• Continuous monitoring

• Superior image quality

• Additional diagnostic planes

• Procedural visualization

Where TEE Changes Practice

1. Cardiac Arrest — From Blind CPR to Visual Resuscitation

TEE enables:

• Identification of reversible causes:

  • Tamponade

  • Massive PE

  • Aortic dissection

  • Severe hypovolemia (Teran et al., 2020; Edmiston et al., 2024)

• Differentiation of:

  • True PEA vs pseudo-PEA

  • Fine VF missed on monitor (Jung et al., 2020; Parker et al., 2018)

• Optimization of CPR:

  • Avoid LVOT compression (Hwang et al., 2009; Cha et al., 2013)

  • Improve compression location

• Reduction in CPR interruptions (Fair et al., 2019)

👉 TEE identifies the cause of arrest in ~25–35% of cases (Prager et al., 2022; Edmiston et al., 2024).

2. Undifferentiated Shock

TEE excels when TTE is inadequate in ICU patients.

It allows:

• LV/RV function assessment

• Obstructive pathology detection

• Volume responsiveness (SVC collapsibility) (Vieillard-Baron et al., 2004)

• Continuous reassessment

👉 Leads to change in diagnosis in ~52–78% and management in ~32–89% of cases.(Prager et al., 2022; Kegel & Chenkin, 2023; Teran et al., 2024).

3. Hemodynamic Monitoring — The Hidden Superpower

TEE enables continuous bedside monitoring, unlike TTE:

• Stroke volume / cardiac output

• Ventricular function trends

• Response to fluids/inotropes

👉 Validated as a monitoring tool in critical care (Vignon, 2017; Porter et al., 2015)

👉 Particularly useful in:

• Sepsis

• Cardiogenic shock

• Mixed shock states

4. Trauma & Acute Care

TEE provides simultaneous diagnosis + resuscitation:

• Blunt aortic injury detection (Osman et al., 2020)

• LVOT obstruction in trauma physiology (Prager et al., 2024)

👉 Critical when CT is not feasible.

5. Procedural Guidance — From Blind to Visual

TEE enhances:

• ECMO cannulation (Fair et al., 2016; Banfi et al., 2016)

• Transvenous pacing (Lerner et al., 2020)

• PA catheter placement (Cronin et al., 2017)

👉 Reduces complications and improves accuracy.

6. Special Situations

• Prone ARDS → TEE remains feasible (Mekontso Dessap et al., 2011)

• COVID / severe hypoxemia → identifies shunts (Teran et al., 2020)

• TELUS → posterior lung imaging (Cavayas et al., 2016)

Real-World Impact (What the Data Shows)

• Diagnostic change: 52–78%

• Management change: 32–89%

• Interpretable images: >98–99% success

• Complications: rare to negligible

(Wray et al., 2021; Arntfield et al., 2018; Reardon et al., 2021; Teran et al., 2024)

👉 This is not just imaging—this is decision-altering technology.

Critical Appraisal — The Balanced View

Advantages

1. Continuous Imaging During CPR

No interruptions → better perfusion

2. High Diagnostic Yield

Especially when TTE fails

3. Real-Time Decision Support

Immediate therapeutic impact

4. Procedural Precision

Safer ECMO, pacing, catheter placement

5. Broad Applicability

Pitfalls

1. Operator Dependence

Requires structured training

2. Misinterpretation Risk

Incorrect findings → wrong interventions

3. Lack of Standardized Protocols

Still evolving (Tseng et al., 2025)

4. Cognitive Load

Can overwhelm inexperienced teams

---

Disadvantages

1. Invasive Modality

Potential complications:

• Esophageal injury

• Oropharyngeal trauma

Though rare (~0.01–0.08%) (Kallmeyer et al., 2001; Ramalingam et al., 2020)

👉 Large ICU series show no major complications (Prager et al., 2022).

2. Training Gap

• Requires TTE foundation

• Simulation-based learning

• Supervised exams (~30 studies) (Charron et al., 2013)

3. Resource Barriers

• Probe cost

• Maintenance

• Credentialing

👉 Major implementation barriers (Teran et al., 2023; McGuire et al., 2022)

4. Limited High-Level Evidence

• Strong observational data

• Limited RCTs

👉 Field still evolving.

👉 TEE is a complement, not replacement.

Where the Field Is Heading (2025–2026)

Recent literature shows:

• Rapid growth in adoption and research (Tseng et al., 2025)

• Expansion beyond arrest → full-spectrum critical care

• Increasing ED uptake (~20% programs in NA) (Teran et al., 2023)

• Emergence of registries and multicenter data (Teran et al., 2024)

👉 We are witnessing the mainstreaming of resuscitative TEE.

Take-Home Points

• Resuscitative TEE is a high-impact tool in acute care

• Most useful in:

  • Cardiac arrest

  • Undifferentiated shock

  • Procedural guidance

• Provides continuous, real-time hemodynamic insight

• Improves:

  • Diagnosis

  • Decision-making

  • Procedural safety

But:

• Requires training

• Needs resources

• Still evolving in evidence
