The aim of this study was to assess the accuracy of multiplane transesophageal echocardiography (TEE) with color Doppler (CD) flow imaging in detecting stenosis of proximal coronary arteries. Coronary lumen and proximal coronary artery flow (PCAF) were evaluated in 10 control subjects (CTR) with normal cardiovascular findings and 15 patients (pts) with coronary artery disease (CAD) that had coronary arteriography performed within two months of TEE. LMCA and proximal portions of LAD, CX and RCA were visualized in 100%, 98%, 97% and 94% of pts. PCAF was recorded in LMCA in 92%, LAD in 85%, CX in 64% and RCA in 67%. Systolic (Vsist) diastolic velocities (Vdiast) were significanly higher in CAD pts compared to CTR. Vsist (cm/s): LMCA 57 +/- 11 vs 41 +/- 13, p<0.01; LAD 49 +/- 10 vs 34 +/- 11,p<0.01; CX 53 +/- 12 vs 33 +/- 9, p<0.05; RCA 37V9 vs 27 +/- 12, p<0.01; Vdiast (cm/s): LMCA 102 +/- 24 vs 68 +/- 17, p<0.01; LAD 88 +/- 11 vs 66 +/- 13, p<0.05; CX 92 +/- 23 vs 77 +/- 15, p<0.01; RCA 69 +/- 12 vs 43 +/- 11, p<0.01.

Abstract
The aim of this study was to assess the accuracy of multiplane transesophageal echocardiography (TEE) with color Doppler (CD) flow imaging in detecting stenosis of proximal coronary arteries. Coronary lumen and proximal coronary artery flow (PCAF) were evaluated in 10 control subjects (CTR) with normal cardiovascular findings and 15 patients (pts) with coronary artery disease (CAD) that had coronary arteriography performed within two months of TEE. LMCA and proximal portions of LAD, CX and RCA were visualized in 100%, 98%, 97% and 94% of pts. PCAF was recorded in LMCA in 92%, LAD in 85%, CX in 64% and RCA in 67%. Systolic (Vsist) diastolic velocities (Vdiast) were significanly higher in CAD pts compared to CTR. Vsist (cm/s): LMCA 57 +/- 11 vs 41 +/- 13, p<0.01; LAD 49 +/- 10 vs 34 +/- 11,p<0.01; CX 53 +/- 12 vs 33 +/- 9, p<0.05; RCA 37V9 vs 27 +/- 12, p<0.01; Vdiast (cm/s): LMCA 102 +/- 24 vs 68 +/- 17, p<0.01; LAD 88 +/- 11 vs 66 +/- 13, p<0.05; CX 92 +/- 23 vs 77 +/- 15, p<0.01; RCA 69 +/- 12 vs 43 +/- 11, p<0.01. There was no significant difference in heart rate between CAD pts and CTR. A 50% lumen stenosis in 2D imaging provided high sensitivity and specificity for detection of significant angiographic stenosis (94-96% for LMCA, 91-94% for LAD, 74-88% for CX and 82-85% for RCA). Sensitivity and specificity were higher combining two-dimensional and Doppler values. Thus, our data suggest that TEE with CD is highly accurate for the assessment of proximal coronary artery stenosis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
