Key result
Large SVG aneurysm causes fatal functional mitral stenosis via left atrial compression.
Why the study?
Venous graft aneurysm with compression and fistula to a cardiac chamber other than the right atrium is a rare and unreported condition.
Case Report (n=1)
This report describes a rare case of a venous graft aneurysm with compression and fistula to a chamber other than the right atrium, causing functional mitral stenosis.

Alerts clinicians to fatal LA compression risk in SVG aneurysms; leaves open optimal surveillance and intervention timing.
We present the case of a patient who presented with acute coronary syndrome and was found to have a mass compressing the left atrium. An angiogram revealed a large saphenous vein graft aneurysm with a fistula into a cardiac chamber, presumed to be the left ventricle. The patient also developed a functional mitral stenosis secondary to this mass causing left atrial compression. The patient passed away prior to receiving surgery. We describe a rare case of venous graft aneurysm with compression and fistula to a chamber other than the right atrium, that to our knowledge has yet to be reported.

Ziffra et al. (2018) conducted a case report in Saphenous vein graft aneurysm and fistula (n=1). Saphenous vein graft aneurysm and fistula was evaluated. A patient with a large saphenous vein graft aneurysm and fistula to the left ventricle developed functional mitral stenosis from left atrial compression and died before surgery.
