Jetbreedte ratio relative LVOT
==Jetbreedte ratio relative LVOT==
Currently the most widely used and best documented measurement to assess the severity of aortic insufficiency , however, it has limitations in poor parasternal ( Plax ) windows and eccentric jets .

Pressure half-time ( PHT )
==Pressure half-time (PHT)==
The pressure half-time is dependent upon both the volume and regurgitation of the diastolic function of the left ventricle ( compliance ) . However, in severe aortic valve insufficiency , the left ventricle rather " full" hit so will the pressure half-time short they cause even an end - diastolic mitral insufficiency occurred . Will also be taken so that the pressure half-time will shorten . Off when poorly tolerated aortic valve insufficiency diastolic function of the left ventricle
