Proximal isovelocity surface area method for assessment of mitral regurgitation severity: Principles, pitfalls, and future directions

Quantification of mitral regurgitation (MR) is important in clinical practice. As fluid approaches a finite circular orifice, concentric hemispherical shells are formed with gradually decreasing surface area and increasing velocity. Severity of MR by the proximal isovelocity surface area (PISA) can...
