MV SV is not a measurement that is part of our labs routine protocol. Its also not a measurement I was taught to do in the presence of MR, AI or suspected shunt(I'm not sure why, but I am going to bring this up). We do, of course, get the LVOT SV as part of the protocol, MV SV seems easy enough to do during a normal MV interrogation. Besides PW placement and cursor alignment, are there any other pitfalls or problems to be aware of measuring an MV SV?
yes it is not in regular protocol. Just making sure trace envelop correctly and MV diameter. practice in normal people (no regurgitation) if SV in both are almost equal, your technique was right otherwise go back and check which of those parameters (LVOT di, VTI , MV di ..) probably performed incorrectly
