Late Migration of Fully Deployed Left Main Coronary Stent into Aortic Root: A Late Complication and Its Surgical Management.

ABSTRACT: Migration and embolization of a deployed stent is a rare complication of percutaneous coronary interventions (PCI) and can result in serious and potentially life-threatening complications. There are many reports of intracoronary stent entrapment, stripping, and dislodgement during PCI, however, only a few reports about migration. We report a rare case of migration of the left main coronary stent into the aortic root, which happened 5 months after the procedure and was treated by its partial removal through aortotomy along with surgical revascularization. The patient was discharged 5 days later, after an uneventful hospital stay.

Complete heart block caused by sinus of valsalva pseudoaneurysm-A rare case.

Acquired pseudoaneurysms of the aortic root involving the sinus of Valsalva (SOV) are rare and serious complications arising from trauma, infection, or following cardiac surgery or intervention. Complete heart block (CHB) is an atypical presentation of SOV pseudoaneurysm due to either direct compression effects or involvement of the main conducting system by blood and inflammatory cell infiltration. Herein, we describe a rare case of a patient who presented with CHB caused by an SOV pseudoaneurysm following polytrauma and was treated with surgical closure of pseudoaneurysm followed by implantation of a permanent pacemaker to treat the persistent CHB.

Aortic root pseudoaneurysm after blunt trauma to chest - an interesting case.

Acquired pseudoaneurysms of the aortic root involving the sinus of Valsalva are rare and serious complications arising from trauma, infection, or following cardiac surgery or intervention. We describe the surgical treatment of a patient who had acquired sinus of Valsalva pseudoaneurysm following blunt trauma to chest; wherein pericardial patch closure of the orifice of the pseudoaneurysm without aortic valve replacement or coronary artery bypass grafting. The management of these sinus of Valsalva pseudoaneurysms depends on the underlying mechanism causing symptoms such as compression or thrombosis of coronary artery; or the defective anatomy involving sinus of Valsalva, aortic valve or the coronary artery.
