Case 12 — Color Flow Doppler

Color flow Doppler in systole showing flow from the RV into the RA — tricuspid regurgitation despite the absence of an audible systolic murmur. The jet is large and fills the RA, suggesting at least moderate to severe TR. LV — left ventricle; LA — left atrium.
Systolic color flow Doppler. TR jet from RV into RA is large, filling the RA (at least moderate to severe) despite the absence of a systolic murmur. LV; LA.
Diastolic color flow Doppler frame showing a jet originating at the pulmonic valve and flowing back into the RV — pulmonic regurgitation. The jet is not large enough to produce an audible diastolic murmur. MPA — main pulmonary artery.
Diastolic color flow Doppler. Pulmonic regurgitation jet flows from the pulmonic valve back into the RV. The jet is too small to produce an audible murmur. MPA.
