Left atrial dissection during percutaneous coronary intervention: Case report and review of literature

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 [1]. We have reviewed literature and describe a case where echocardiography led to early recognition of this rare entity.
