It is clearly important that the medical profession plays a significant role in critically
evaluation of the use of diagnostic procedures and therapies in the management or …

OBJECTIVES.: We attempted to determine the accuracy and pitfalls of calculating the mitral
regurgitant orifice area with the proximal isovelocity surface area method in a clinical series …

Background Although Doppler color flow mapping is widely used to assess the severity of
mitral regurgitation (MR), a simple, accurate, and quantitative marker of MR by color flow …

Background In patients with chronic heart failure, the use of carvedilol therapy induces
clinical and hemodynamic improvement. However, although the benefits of this β-blocker …

Background Quantitative Doppler echocardiography and proximal flow convergence
methods are validated techniques for quantifying mitral regurgitation. However, the clinical …

Objectives. The feasibility of velocity-encoded cine nuclear magnetic resonance (NMR)
imaging to measure regurgitant volume and regurgitant fraction in patients with mitral …

Mitral valve regurgitation is a relatively common and important heart valve lesion in clinical
practice and adequate assessment is fundamental to decision on management, repair or …

Objectives: This study sought to determine the effect of dynamic variations of mitral
regurgitant flow rate (MRFR) and effective regurgitant orifice area (EROA) on mitral …

Background Proximal flow convergence is a promising method to quantify mitral
regurgitation but may overestimate flow when the flow field is constrained. This has not been …

Background In patients with mitral valve prolapse, spontaneous changes of the effective
regurgitant orifice during systole are not well documented. Such changes can now be …
