A 52-year-old woman with no cardiovascular risk factors was admitted to our emergency department because of acute limb pain because of arterial ischemia. An urgent angio-computed tomography (CT) scan described acute occlusion of left common iliac artery [Figure 1]a, with a fragment of embolus wedged on the iliac carrefour [Figure 1]b, occlusions of right popliteal artery [Figure 1]c and right internal iliac artery [Figure 1]d, sub-occlusion of superior mesenteric artery at its bifurcation, and diffused ischemic lesions in both kidneys [Figure 1]e and spleen. A CT scan of the brain also revealed small bilateral multiple ischemic injuries. Shortly after admission, the patient developed acute lung edema and a transthoracic echocardiogram showed severe left ventricular dysfunction due to apical ballooning. The diagnosis of takotsubo syndrome was confirmed with a coronary angiogram, which excluded epicardial coronary artery disease or coronary embolic lesions and was supported also by diffuse deep negative T-waves on the electrocardiogram without relevant increase of cardiac enzymes. A transesophageal echocardiogram was able to reveal an 11 mm × 3 mm mass in the left atrium, attached to the interatrial septum next to the posteromedial commissure of mitral valve [[Figure 1]f and [Figure 1]g and Video 1]. It was heterogeneously iso-hyperechogenic, pedunculated and had a high diastolic motion with protrusion through the atrioventricular plane. No intraventricular thrombosis was evident [Video 2]. The patient underwent urgent vascular and heart surgery and histologic analysis on the specimens from both arterial emboli and cardiac mass confirmed their myxomatous nature. In conclusion, this case emphasizes the potential malignancy of left-sided myxomas in terms of embolic complications and underlines the fundamental role of transesophageal echocardiography in identifying the correct source of embolism, particularly in the presence of confounding factors, such as in this case a Takotsubo syndrome, whose onset was a consequence of the massive embolization itself.
