Tóm tắt

OBJECTIVES: To evaluate the accuracy of regurgitant volume calculated by volumetric transthoracic echocardiography (RegVol_ BACKGROUND: Recent studies have shown suboptimal results of the proximal isovelocity surface area (PISA) method and the American Society of Echocardiography (ASE) algorithm for diagnosing severe primary MR. METHODS: A total of 74 patients with primary MR due to prolapse or flail leaflet were prospectively recruited for both TTE and cardiac magnetic resonance imaging (CMR). RegVol was calculated using PISA (RegVol_ RESULTS: All subjects had at least moderate to severe MR based on ASE guidelines. CMR confirmed that 30 patients (41%) had severe MR. The concordance correlation coefficient between RegVol_ CONCLUSIONS: RegVol_
