other technical advantages of this device are : 1 ) prevention of looping and bending of the balloon catheter in tortuous vessels and easy positioning of the balloon across the aortic orifice provided by the ls trackability , 2 ) stabilisation of the balloon during inflation , 3 ) monitoring of supravalvular aortic pressure provided by the side-arm of the ls and reliable measurement of systolic gradient , and 4 ) the ability to perform aortograms without the need of another catheter in the ascending aorta .
