Abstract:
The first successfully diagnosed and treated case of aorta–
right atrial tunnel was reported by Coto et al. in 1980. The
most common cause of aorta–right atrial tunnel is a ruptured
aneurysm of the sinus of Valsalva. Sinus of Valsalva aneurysms
had been reported as early as 1840 by Thurnam; these
were diagnosed at autopsy. With the advances in radiology,
many cases of aorta–right atrial tunnel have been reported
since then, each with its own subtle variations.
We report on a unique case of aorta–right atrial tunnel
with a windsock aneurysm in the right atrium. A 55-yearold
male presented with abdominal pain and the chest X-ray
revealed cardiomegaly. On further investigation with echocardiography
and computed tomography angiography, there
was an incidental aorta–right atrial tunnel with a windsock
aneurysm in the right atrium. He was treated successfully
with surgery. A similar case has been reported only once
before by Iyisoy et al. in 2014.
