Loc: Boston,Massachusetts U.S.A. I have a question on wedding traditions, I was hoping that you might enlighten me.. In Spain the wedding ring is put on the right hand while in the U.S it is on the left hand..
Doppler assessment of area by pressure half-time method ï§ The time required for the mitral diastolic pressure to fall by 50% ï§ Mitral valve area is calculated as: 220 â pressure half time (msec).
The purpose of this study was to compare the Doppler and catheterization pressure half-time methods of estimating mitral valve area with valve areas obtained by the Gorlin equation in a group of patients with clinically significant mitral stenosis.
