Abstract Introduction Cardiopulmonary complications are a major cause of morbidity and mortality in sickle cell disease (SCD) as shown by worse prognosis in patients who have experienced acute chest syndrome or who have an elevated tricuspid regurgitant [bloodjournal.org]

The prognosis for patients whose VSDs either closed spontaneously or through surgery before the development of pulmonary vascular disease is excellent, with no exercise restrictions and normal life expectancy. [pted.org]

Here we describe an unexpected and novel cardio-pulmonary complication in HbSS, right-to-left shunting through extra-cardiac arterial-venous malformations (AVMs), which may contribute to pathophysiology. [bloodjournal.org]

Pathophysiology Significant left to right shunting can occur resulting in a high left ventricular cardiac output. Forward systemic flow can be reduced if the shunt is large resulting in symptoms of congestive heart failure. [healio.com]

When detected, RLS is generally secondary to an atrial level shunt (i.e., PFO), but noncardiac RLS (primarily intrapulmonary) has also been implicated in the pathophysiology of clinical conditions resulting from paradoxical embolism ( 1 ). [interventions.onlinejacc.org]
