Pulmonary Hypertension Caused by a Coconut Left Atrium
EC Leung, N Hirani et al.
KEYWORDS
pulmonary hypertention; coconut left atrium; chest x-ray image
“Coconut atrium” was first described in 1898 and is most commonly
associated with rheumatic heart disease. This case demonstrates a
dramatic chest x-ray image of extensive circumferential calcification of
the left atrium. The abnormality was thought to result in elevated
pulmonary pressures and severe right heart failure in the absence of
significant mitral valve dysfunction.
