Venous Return

Anomalous pulmonary venous return.

are, however, generally lacking. For purposes of this presentation, 113 selected instances of anomalous pulmonary venous return encountered at Brooke General Hospital, Walter Reed General Hospital, and the Registry of Cardiovascular Pathology of the Armed Forces Institute of Pathology have been reviewed and correlated with related material from the literature. To obtain completeness, tempered w...

Understanding Guyton's venous return curves.

Based on observations that as cardiac output (as determined by an artificial pump) was experimentally increased the right atrial pressure decreased, Arthur Guyton and coworkers proposed an interpretation that right atrial pressure represents a back pressure restricting venous return (equal to cardiac output in steady state). The idea that right atrial pressure is a back pressure limiting cardia...

[Partial anomalous pulmonary venous return].

A 51-year-old man with no cardiovascular symptoms was referred for cardiac magnetic resonance imaging (CMRI) for further investigation of alterations observed on previous exams. CMRI revealed biventricular dilatation and paradoxical septal motion compatible with volume overload. Balanced steady-state free precession sequences in axial planes showed an anomalous vein oriented vertically and late...
