Quantitative, non-invasive assessment of ventricular septal defect shunt flow by measuring proximal isovelocity surface area on colour Doppler mapping

摘要

Conclusions-These data suggest that the PISA method is a reliable non-invasive Investigation for the quantitative assess- Ment of VSD shunt flow and provides Important information for decisions Regarding surgical repair. Objective-To determine whether the Proximal isovelocity surface area (PISA) Method could be applied to estimate the Magnitude of ventricular septal defect (VSD) shunt flow. Design-Prospective analysis of clinical, Echocardiographic, and angiographic Data.
