Abstract
soephageal/transgastric approach. We investigate wether DJW could be used as an indicator of MR severity. Methods: DJW was obtained in 52 pts with MR (male 63%, mean age 63 years) using transesophageal (0° or 120°) or transgastric (90°) views and compared with the effective regurgitant orifice (ERO), the pulmonary venous flow systolic reversal, and the Sellers’ angiographic grade whenever available. Results: MR etiology included degenerative (42%), ischemic (25%), functional (21%), infective (8%), rheumatic (4%). Mean ± SD ERO and DJW were 0.45 ± 0.39 cm 2 and 0.9 ± 0.35 cm respectively. Fair correlations were observed between DJW and ERO (r=0.71, p /= 0,9 cm predicted an ERO >/= 0,3 cm2 with 76% sensitivity (95% CI 65-88%), 82% specificity (95% CI 71-92%), 85% positive predictive value (95% CI 75-95%), 72% negative predictive value (95% CI 59-84%) and an overall accuracy of 78% (95% CI 67-89%). Conclusions: In this study, the DJW measured by color Doppler during TEE correlated well with the other methods of MR evaluation. This measure could provide an additional and accurate tool to be validated in larger populations. 876 Detection of coronary artery disease by dobutamine echocardiography stress test in patients with moderate aortic stenosis in subgroups with and without hypertension: safety and accuracy.
