Computed tomography images of the heart .
Panel A . axial scan: from a caudal view the reader can recognize
the PV as the most anterior (in the superior aspect of the image)
structure of the heart in close contact with the basal septum and aortic
root. The space between LPC, LCC and LVOT is the LV summit. While the PV
is cut “on face”, the AV is cut “on edge”. Panel B : sagittal
scan: from a left side view is clearly appreciable the closeness between
LPC and Left Main coronary artery. In this projection the PV is cut “on
edge”, while the AV is cut “on face”. The PV lies at a level just
superior to the AV and runs on an oblique plan (from antero-superior
towards postero-inferior position). LV: left ventricle, RV: right
ventricle, AV: aortic valve, PV: pulmonary valve, APC: anterior
pulmonary cusp, RPC: right pulmonary cusp, LPC: left pulmonary cusp,
LCC: left coronary cusp, RCC: right coronary cusp, NCC: non coronary
cusp, LVOT: left ventricle outflow tract, RVOT: right ventricle outflow
tract, RA: right atrium, RAA: right atrial appendage, LA: left atrium,
LAA: left atrial appendage, LM: left main
