Criteria developed to consistently and repeatably identify AVP on right parasternal long and short axis cineloops of the left ventricular outflow tract (LVOT) and aortic valve (AoV)
| A) RIGHT-SIDED PARASTERNAL LONG-AXIS VIEW OF THE LVOT AND AOV | B) RIGHT-SIDED PARASTERNAL SHORT-AXIS VIEW OF THE AOV |
|---|---|
| · Image obtained from RICS4 |
· Images obtained from the RICS4 |
| · IVS perpendicular to the ultrasound beam |
· AoV centred in the middle of the image with all three cusps visible |
| · Walls of the Ao parallel |
· TV in the near field of the image |
| · Two AoV cusps visible | · PV in the far field of the image |
Abbreviations: Ao – aorta; IVS – inter-ventricular septum; PV – pulmonary valve; RICS4 – right 4th intercostal space; TV – tricuspid valve.
