Abstract

AIM:

Assessment of pulmonary valve (PV) and right ventricular outflow tract (RVOT) using real-time 3-dimensional echocardiography (RT3DE).

METHODS:

Two-dimensional echocardiography (2DE) and RT3DE were performed in 50 patients with congenital heart disease (mean age 32 +/- 9.5 years, 60% female). Measurements were obtained at parasternal views: short axis (PSAX) at aortic valve level and long axis (PLAX) with superior tilting. RT3DE visualization was evaluated by 4-point score (1: not visualized, 2: inadequate, 3: sufficient, and 4: excellent). Diameters of PV annulus (PVAD), and RVOT (RVOTD) were measured by both 2DE and RT3DE, while areas (PVAA) and (RVOTA) by RT3DE only.

RESULTS:

By RT3DE, PV was visualized sufficiently in 68% and RVOT excellently in 40%. PVAD and PVAA were measured in 88%. RVOTD and PVAD by 2DE at PLAX were significantly higher than PSAX (P < 0.0001) and lower than that by RT3DE (P < 0.001).

CONCLUSION:

RT3DE helps in RVOT and PV assessment adding more details supplemental to 2DE.
