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]

The fact that the secondary RLS group had more atrial septal aneurysms and a larger balloon waist diameter would also suggest that incomplete balloon occlusion of large, floppy PFOs is a more likely source of RLS than an intrapulmonary etiology. [interventions.onlinejacc.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 General pathophysiological processes The left chambers of the heart are a high-pressure pump system and the right chambers of the heart are a low-pressure pump system. [amboss.com]

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]

This wall prevents mixing of oxygenated pure blood with deoxygenated impure blood. However, in right to left cardiac shunt the deoxygenated blood mixes with the pure oxygenated blood in the left side, surpassing the pulmonary circulation. [tandurust.com]
