[Left intraventricular thrombosis. From diagnosis to treatment].

Left ventricular thrombi are the source of much concern in numerous conditions affecting the ventricles. Refinement in echocardiographic and isotopic techniques is enabling earlier diagnosis and a more rational approach to therapy. These thrombi occur very frequently, and are most often asymptomatic (more than 2 to 3 times out of 4), and their natural course is not well known. Recent studies have dealt with acute ischemic cardiopathies, but these should not obscure the fact that thrombi occur with similar frequency in chronic conditions, in particular, hypokinetic cardiomyopathies. Three recent cases emphasize this, demonstrate the frequency of these thrombi, and help illustrate available diagnostic methods and a practical approach to this condition. These recent developments only confirm the importance of effective anticoagulation in all patients at risk and the necessity of optimal treatment with inotropic agents which do not suppress thrombus formation, but appear to prevent their complications.
