“…Using the modalities available with 3D TTE, cusp number, thickness, and mobility can be determined in patients with PV diseases such as congenital PV diseases, PV masses, PV carcinoid valvulopathy, and PV endocarditis 2,4,5,14,15,27,30–35 . Additionally, 3D TTE provides accurate RV outflow tract supravalvular, subvalvular, and valvular measurements in patients with congenital RVOT obstruction 2,5,6,36 . 3D TTE also improved the accuracy in the assessment of pulmonary regurgitation (PR), which has implications in determining the timing of surgical intervention 24,27,37 …”
