Extrinsic tricuspid valve compression due to an aortic aneurysm causing significant right to left shunt via a patent foramen ovale: a case report.

ABSTRACT:

Background

Aortic aneurysms are known to cause compression of adjacent structures including the tracheobronchial tree, oesophagus, and recurrent laryngeal nerve. Extremely rarely, they can lead to compression of the tricuspid valve (TV) annulus. We describe a case where aortic aneurysm caused TV annulus compression and persistent right-to-left shunt through a patent foramen ovale (PFO).

Case summary

A 75-year-old female was admitted with headache and dizziness. On examination, she had persistent arterial desaturation with oxygen levels reduced to 69% at rest whilst breathing ambient air. Complete blood count demonstrated polycythaemia (Hb 174 g/L). Right to left cardiac shunt was suspected after significant lung and haematologic pathology was excluded. Transoesophageal echoc
