The paper entitled “Quantification of Multiple Mitral Regurgitant Jets: An In Vitro Validation Study Comparing Two- and Three-Dimensional Proximal Isovelocity Surface Area Methods” by Zürcher et al., published in the May 2017 issue of JASE (J Am Soc Echocardiogr 2017;30:511-21), has a correction. The publisher would like to apologise for any inconvenience caused. On page 515, Table 1 should appear as follows:
