Asymptomatic Giant Left Atrium: Do Atrial Size Changes After Successful Valve Replacement 7-Years Follow-up Case Report

Background: Giant left atrium (GLA) associated with mitral valve surgery reported to have a mortality rangingfrom 8% to 32%. Most of the patients are symptomatic with that of shortness of breath, dysphagia, palpitations,chest pain, and thromboembolic events. Asymptomatic giant enlargement of the left atrium is rare. Either we mustdo or not do a reduction arterioplasty at the time of the mitral valve surgery is a controversy in the literature.Case Report: The patient had mitral valve replacement with a with a 31 mm carbomedics mechanical valveprosthesis 7 years past during her last visit. No reduction arterioplasty was done with a valve operation. Her 7-yearsclose follow-up was uneventful. In the last visit, echocardiography and spiral chest computerized tomographyscanning were requested. In both of the requested images giant left trial enlargement was seen, but the patient waswithout symptoms regarding her giant left atrium.Conclusions: In this case report, it seems that if we want left atrial size decline, it is necessary to havereduction arterioplasty during mitral valve surgery. However, it does not mean a definite therapeutic efficacy,especially when considering future symptoms.© 2014 Tehran University of Medical Sciences.
