Results The detecting rates of the displacement of the mitral coaptation point ,the flail partial mitral leaflets,the coarse and erratic flutter of flail leaflets, the flicking mitral chordae tendineae with coarse and erratic flutter and the vegetation by TEE and TTE with 2-D were 100%and 94.3%, 100%and 65.7%, 85.7%and 54.3%, 77.1%and48.6%, 100%and33.3%, respectively.With color Doppler imaging,eccentric wall jets or eccentric-centric jets were all detected by TEE and TTE, respectively. The regurgitant volume based on PISA method by TEE and TTE was(2025±402)and (607±268)ml/min,respectively.

In the buckling question under nonconservation force,a simply example( the dynamic stability question under the uniformly follower forces with small deformation % linear elastic, straight normal.) is considered.The variational equation of braid composite cylindrical shells subjectd to uniformly follower forces is deduced based on the variation principle of quasinatural frequency of elastic nonconservative system self-excited vibration.The calculated formulas of the flutter load and quasinatural frequency of shells are obtained. The program for calculating the flutter load is developed.The numerical example is given and some useful conclusions are obtained.
