The presence of concurrent mitral regurgitations in patients with aortic stenosis (AS) is common. The guidelines recommend concomitant surgical therapy in the presence of severe mitral regurgitation (MR) at the time of surgical treatment for severe aortic stenosis [ , ]. The authors of a manuscript in this issue of the journal are correct in explaining that treating aortic stenosis improves forward flow, decreasing transmitral systolic gradients and reducing functional mitral regurgitation [ ]. Several studies have demonstrated that mild functional mitral regurgitation is more likely to improve than moderate or severe mitral regurgitation after surgical aortic valve replacement (SAVR) [ ].
