Real-Time Three-Dimensional Echocardiographic Assessment of Severity of Mitral Regurgitation Using Proximal Isovelocity Surface Area and Vena Contracta Area Method. Lessons We Learned and Clinical Implications
Mitral regurgitation (MR) is considered the most common valve disease with a prevalence of 2-3 % of significant regurgitation (moderate to severe and severe) in the general population. Accurate assessment of the severity of regurgitation was demonstrated to be of significant importance for patient management and prognosis and consequently has been widely recognized in recent guidelines. However...
متن کاملEffective mitral regurgitant orifice area: clinical use and pitfalls of the proximal isovelocity surface area method.
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 that included patients with valvular prolapse and eccentric jets. BACKGROUND The effective regurgitant orifice area, a measure of lesion severity of mitral regurgitation, can be calculated by the proximal isove...
متن کامل3D vena contracta area to quantify severity of mitral regurgitation: a practical new tool?
M itral regurgitation (MR) is a common form of valvular disease1 and its severity is associated with excess morbidity and mortality from left ventricular (LV) remodeling, left atrial remodeling, pulmonary pressure elevation, and progression to left and right heart failure.2-6 Current American Society of Echocardiography (ASE) Guidelines7 propose vena contracta (VC) width as a simple semi-quanti...
متن کاملProximal isovelocity surface area should be routinely measured in evaluating mitral regurgitation: a core review.
The proximal isovelocity surface area (PISA) measurement, also known as the "flow convergence" method, can be used in echocardiography to estimate the area of an orifice through which blood flows. It has many applications, but this review focuses only on its use in the intraoperative evaluation of mitral regurgitation. In that setting, PISA provides a quantitative assessment of the severity of ...
متن کاملPRO: Proximal isovelocity surface area should be routinely measured in evaluating mitral regurgitation.
Jack S. Shanewise, MD Proximal isovelocity surface area (PISA) should be part of every transesophageal echocardiography evaluation of mitral regurgitation (MR) (1). Although most of us think of formulae and calculations when we hear the term PISA, it is most useful as a qualitative indicator of the presence and severity of MR. Just as we use color flow Doppler (CFD) to see the regurgitant jet i...
