Figure 3. Transthoracic echocardiography on admission. (A) RV dilatation and D-shaped interventricular septum during diastole, consistent with RV volume overload. (B) Severe tricuspid regurgitation with TR gradient of 64 mmHg. 2D vena contracta was 7.6 mm and hepatic vein systolic flow reversal was present. RA pressure was 10–20 mmHg. (C) Flow acceleration at the level of the pulmonary valve. (D) Moderately increased peak transpulmonary gradient of 44 mmHg. Subtracting the gradient across the pulmonary valve from RV systolic pressure yields the PA systolic pressure. In this case, the calculated PA systolic pressure is 30–40 mmHg.
