A giant left ventricular pseudoaneurysm diagnosed after double-valve replacement

A diagnostic coronary catheter injury to the subaortic region in a 41-year-old woman with rheumatic heart disease led to a pseudoaneurysm that later caused extrinsic left coronary compression. She subsequently underwent double-valve replacement, overlooking the pseudoaneurysm that enlarged to a giant size three months later following thrombolysis for mitral prosthesis thrombosis. A thrombolysis-induced large intracerebral hemorrhage posed a significant risk for reoperation, and mechanical prosthetic valves in the aortic and mitral positions allowed a catheter option only, through percutaneous transapical access. Interventional closure of the pseudoaneurysm is discussed in this unique report.
