A new Valsalva blowing device in the diagnosis of right-to-left shunt using contrast-enhanced transcranial Doppler ultrasound
The modified Valsalva device has higher sensitivity in the diagnosis of RLS than the traditional Valsalva maneuver, especially for higher grade shunting severity. It can be used as an alternative to the traditional Valsalva maneuver in c-TCD screening, particularly in patients who have difficulty performing the traditional Valsalva maneuver.
