[Embolic intracardiac thrombosis on a catheter for permanent stimulation. An echocardiographic finding].

If endovenous thromboses on permanent cardiac stimulation catheter are rather frequent, it is usual to note the absence of complications, especially embolic complications. On the contrary, intracardiac thromboses, occurring always on a permanent stimulation catheter, are rare but may generate embolisms: the authors report a new case discovered on bidimensional sonocardiography recorded following pulmonary embolisms.
