Why the study?
Does single-plane TEE detect left ventricular segmental wall-motion abnormalities as reliably as biplane TEE in adults undergoing cardiac or vascular surgery?
Population
41 consecutive adults undergoing cardiac or vascular surgery
Comparison
Single-plane transesophageal echocardiography vs Biplane TEE (longitudinal plane cross sections)
Design
Cross-sectional, Analyzed by independent investigators
Follow-up
Intraoperative

Single-plane TEE may miss SWMA detectable only longitudinally; leaves open whether biplane TEE improves perioperative detection.
Does single-plane TEE detect left ventricular segmental wall-motion abnormalities as reliably as biplane TEE in adults undergoing cardiac or vascular surgery?
Single-plane TEE misses approximately 35% of segmental wall-motion abnormalities that are exclusively detectable via longitudinal planes using biplane TEE.
Rouine‐Rapp et al. (1996) studied this question.
