Percutaneous treatment of an occlusive left main pseudoaneurysm: a role for multimodality imaging.

A pseudoaneurysm with compression of the left main coronary artery causing significant ischaemia was successfully treated with a covered stent. We report this rare complication of cardiac surgery for infective endocarditis with a large root abscess. The patient developed a pseudoaneurysm arising from the body of the left main and causing compression of this vessel following his fourth redo aortic valve replacement for staphylococcal endocarditis. The endocarditis had been successfully managed and ongoing infection was excluded. The patient was then treated percutaneously with a covered stent that excluded the aneurysm and relieved the stenosis in the vessel.
