Left Atrial Dissection after Mitral Valve Replacement Demonstrated by Transesophageal Echocardiography

ABSTRACT

Left atrial dissection is one of extremely rare complications associated with mitral valve surgery. We reported a case of left atrial dissection, which was developed after mechanical mitral valve replacement and was demonstrated by transesophargeal echocardiography. The cause of dissection was due to excessive traction of left atrial endocardial layer during surgery.
