late diagnosis of large left ventricular pseudoaneurysm after mitral valve replacement and coronary artery bypass surgery by real-time three-dimensional echocardiography

one of the most serious complications of mitral valve replacement is left ventricular rupture and pseudoaneurysm formation, which is rare but potentially lethal. we herein present a late type of post mitral valve replacement and coronary artery bypass surgery pseudoaneurysm in a 74-year-old female, who was admitted to our hospital with a recent history of exertional dyspnea. she had the above-mentioned operation 10 months before. the diagnosis was made via two-dimensional and real-time three-dimensional transthoracic echocardiography. the prosthetic mitral valve was removed, and the large orifice of the pseudoaneurysm was closed by surgery. at one year's follow-up, the patient was in good condition.
