When there is reversal of flow in a patent ductus arteriosus, there are, as a necessary part of the picture, hypertension in the pulmonary artery and marked increase in pulmonary vascular resistance.

Long-standing aorto-pulmonary shunting in PDA can lead to pulmonary hypertension and left ventricular dysfunction over time. Transcatheter occlusion has become a well-established alternative to ...

The most recordable sequence of transition change of shunt flow pattern for clinically significant PDA was: pulmonary hypertension pattern, to growing pattern, to pulsatile pattern, to closing pattern ...

where a blood vessel called the ductus arteriosus fails to close after birth. This condition can lead to serious health issues, including heart failure and pulmonary hypertension, due to the ...

A term, healthy infant presented with respiratory distress and severe pulmonary hypertension (PH ... A 12 mm secundum ASD and a large patent ductus arteriosus (PDA) were present with bidirectional ...

FAPI PET—can detect the first signs of tissue remodeling in patients with pulmonary arterial hypertension (PAH), providing ...

Exercise PH — measured by the mPAP/CO slope — may predict survival in patients with normal or mildly elevated pulmonary arterial pressure.

Forty five were excluded because of an already closed duct in 40 (47%), PDA with minor shunting and respiratory improvement in two, severe right to left shunting through the ductus due to pulmonary ...
