Key result
TEE improves detection of thrombi and abnormal leaflet restriction by ~39% versus TTE.
Why the study?
The study aimed to evaluate primary echocardiographic features, hemodynamic profiles, and comparative diagnostic utility of TTE and TEE in patients with artificial mechanical valve thrombosis.
Does TEE improve the structural detection rate of mechanical valve thrombosis compared to TTE?
Observational (n=48)
No
Does TEE improve the structural detection rate of mechanical valve thrombosis compared to TTE?
Absolute Event Rate: 95.8% vs 68.8%
p-value: p=< 0.01
TEE provides superior structural visualization of mechanical valve thrombosis compared to TTE, though TTE remains highly sensitive for detecting secondary hemodynamic modifications.

May support TEE for structural assessment of mechanical valve thrombosis; leaves open management impact in this observational cohort.
Hong et al. (2026) conducted an observational in Artificial mechanical valve thrombosis (n=48). Transesophageal echocardiography (TEE) vs. Transthoracic echocardiography (TTE) was evaluated on Structural detection rate for thrombi and abnormal leaflet restriction (p=< 0.01). Transesophageal echocardiography (TEE) had a higher structural detection rate for thrombi and abnormal leaflet restriction than transthoracic echocardiography (95.8% vs 68.8%, P<0.01).
