Tipping the balance: chronic superior vena cava thrombosis resulting in an aberrant and inefficient venous circuit

Abstract

Given there was no direct flow into the right atrium from the SVC, we deemed this inefficient venous circuit responsible for her breathlessness, with a small reduction in cardiac function 'tipping the balance' and producing symptoms this late in life. The patient opted for conservative management with the risk of intervention outweighing her currently manageable symptoms.
