Indirect signs of pulmonary hypertension
There are several signs which should raise the attention to a possible presence of pulmonary hypertension:
There are several signs which should raise the attention to a possible presence of pulmonary hypertension:
- Cardiac morphology
Increased dimensions of right heart chambers, abnormal shape and function of the interventricular septum, increased RV wall thickness and dilated main pulmonary artery [8]. The shape of the interventricular septum allows an echocardiographic differentiation of RV pressure overload vs. volume overload, if right sided heart chambers are enlarged.
((to add: echo picture and clip of a severe cor pulmonare))
- Doppler echocardiographic signs
A short acceleration time of RV ejection in the pulmonary artery, increased velocity of pulmonary valve regurgitation, notching of pulmonary valve (midsystolic closure of the pulmonary valve at high speed sweep), short isovolumic relaxation time (best measured on RV TDI), diminished or absent atrial wave (a-wave) of the pulmonary valve.
Hepatic vein velocity has a characteristic pattern in patients with pulmonary hypertension. Increased diastolic pressure and decreased compliance of the right ventricle results in a prominent atrial flow reversal in the hepatic vein.
