Introduction: Either abnormalities in blood flow , blood vessel wall or interaction between blood constituents may be needed for developing intracardiac thrombus . Among these , impaired LV function may play an important role . We present a case with rapid developing LV thrombus due to LV dysfunction and therefore spontaneous resolution one month later as LV function imporved.
Case report: A 42- year- old male worker , suffered from short of breath for 2 months . Alcohol related dilated cardiomyopathy was firstly impressed . Echocardiography showed generalized hypokinesis LV without regional wall motion abnormality ( EF 53.7% ) . Another echocardiography performed 1 year later for his intolerant dyspnea and a worse LV function with EF 28% noticed .A mass sized 2.2 x 1.2 cm over LV apex found four months later which suspected thrombus . Warfarin prescribed thereafter according to the prothromin time . Surprisingly , the previous LV tumor disappeared one month later and no longer exist in the following 3 months although the antithrombotic therapy seemed suboptimal for goal INR .
Conclusion: LV systolic dysfunction may play an important role in the development of intracardiac thrombus . Antithromic therapy and any attempt to enhance the LV function can help to reduce the possibility of further embolic event and even get resolution of thrombus.
