Regarding “Estimation of Stroke Volume and Aortic Valve Area in Patients with Aortic Stenosis: A Comparison of Echocardiography versus Cardiovascular Magnetic Resonance”

With great interest, we enjoyed reading the article by Dr. Guzzetti et  al.,1 who further demonstrated the methodological insights of measurement of left ventricular outflow tract (LVOT) diameters. The study showed that LVOT was not “rectangular” (as suggested by the guidelines).2 Different methods can significantly impact stroke volume (SV) calculation by Doppler echocardiography compared with cardiac magnetic resonance.
