Introduction
Left atrial dissection is a rare complication of cardiac surgery and percutaneous cardiac procedures. It is defined as a false blood-filled cavity or lumen from mitral annular area to the left atrial free wall or into the atrial septum thereby creating a new chamber with or without communications with the true left atrium. It has been most commonly described following mitral valve surgery .
Cases of left atrial dissection have also been reported following aortic valve surgery chest, CABG, trauma acute MI, infective endocarditis, radiofrequency ablation for atrial fibrillation and rarely following percutaneous coronary interventions. The case we describe here occurred in the setting of a percutaneous coronary intervention, such occurrence is less common. The purpose of our case report is to increase recognition of this rare but potentially lethal complication and to review management strategies.
