| Description|| |
A 42-year-old man, a smoker, but without any other major cardiovascular risk factor or previous cardiac illness, presented with sudden-onset severe pain in the right lower limb for 1 day. Clinical examination revealed decreased mobility with loss of sensation in the right foot, along with absent distal right lower-limb pulses (posterior tibial and dorsalis pedis). An urgent lower-limb arterial Doppler scan was performed which revealed thrombotic occlusion of the right iliac, femoral, and popliteal arteries. Based on these findings, the patient was diagnosed as a case of acute thromboembolic occlusion of the right lower-limb arteries, requiring urgent limb salvage surgery.
Further evaluation was performed as part of the preoperative workup and also to elucidate the cause of embolism. A 12-lead electrocardiogram (ECG) was done which showed normal sinus rhythm with QS pattern in the precordial leads V1–V4, suggestive of old anterior wall myocardial infarction (MI) [Figure 1]a. Cardiac enzymes (troponin I) were within normal limits. Transthoracic echocardiography [Figure 1]b and [Figure 1]c revealed dyskinetic left ventricular (LV) apex with LV ejection fraction of 45% by the modified Simpson's method. The valves were structurally normal. However, there was a giant, elongated, tubular echo-dense mass, attached to the LV apex and extending into the LV outflow tract and even crossing the aortic valve during systole. The mass was 7 cm long and 3 cm wide at the base and was occupying much of the LV volume. The echocardiographic appearance and the clinical presentation were highly suggestive of this mass to be a thrombus.

The patient underwent urgent surgical embolectomy with Fogarty catheter through the common femoral artery. The procedure was successful, with restoration of the right lower-limb pulses, normalization of the skin temperature, and gradual recovery of the right foot movement. The patient was then advised coronary angiography followed by surgical removal of the LV thrombus and coronary revascularization, as required. However, he refused for any further invasive intervention and was eventually discharged on oral anticoagulant therapy.
LV thrombus formation is a well-recognized complication of MI, especially anterior wall MI., LV thrombosis is also known to occur in other conditions that result in LV systolic dysfunction or those associated with hypercoagulable state., Apex is the most common site for LV thrombus formation, and the thrombi can be of various sizes. However, it is extremely uncommon to find such large thrombi extending from LV apex to the aortic valve and beyond.,, Ours was thus a unique case. Although he did not have any history suggestive of MI in the past, the ECG and echocardiography were virtually diagnostic of old anterior wall MI.
