          Introduction: Takotsubo syndrome (TTS) may be complicated by left-ventricular (LV) thrombus formation in 1.3–5.3% of patients. Risk factors for thrombi comprise apical TTS, elevated levels of C-reactive protein and troponine, thrombocytosis, persisting ST segment elevation and right-ventricular involvement. Embolic risk appears high, and anticoagulation is recommended. Case Presentation: We present 3 females, aged 60–82 years, with TTS-associated LV thrombi and cerebral embolism despite therapeutic anticoagulation. Two patients showed apical and 1 patient midventricular ballooning. In 2 patients LV thrombi had not been present at the first echocardiographic examination. LV thrombi were multiple and highly mobile in 2 patients; 1 patient had a single immobile thrombus associated with spontaneous echocardiographic contrast (SEC). In each case, 3 of the described risk factors for LV thrombus formation were identified. The embolic stroke occurred 41–120 h after TTS symptom onset and 21–93 h after the initiation of therapeutic anticoagulation. Two patients were discharged with a neurological deficit, and 1 of them eventually died as a consequence of the stroke. LV thrombectomy to prevent embolism, which has been reported in a small number of cases, had not been considered in our patients. Conclusion: At present, the management of patients with TTS-related thrombi is still unclear, and further studies are urgently needed to assess the best methods for imaging and anticoagulation and to determine the role of thrombolysis and cardiac surgery. Until these studies are available, we suggest the following approach: patients with a TTS-related thrombus should be monitored by echocardiography while receiving anticoagulation. In case of highly mobile LV thrombi, the heart team may consider cardiac surgery to prevent systemic embolism. The role of SEC in TTS remains to be determined.

          Natural history and expansive clinical profile of stress (tako-tsubo) cardiomyopathy.

          This study was designed to define more completely the clinical spectrum and consequences of stress cardiomyopathy (SC) beyond the acute event. Stress cardiomyopathy is a recently recognized condition characterized by transient cardiac dysfunction with ventricular ballooning. Clinical profile and outcome were prospectively assessed in 136 consecutive SC patients. Patients were predominantly women (n = 130; 96%), but 6 were men (4%). Ages were 32 to 94 years (mean age 68 +/- 13 years); 13 (10%) were 2 months in 5%. Right and/or left ventricular thrombi were identified in 5 patients (predominantly by CMR imaging), including 2 with embolic events. Three patients (2%) died in-hospital and 116 (85%) have survived, including 5% with nonfatal recurrent SC events. All-cause mortality during follow-up exceeded a matched general population (p = 0.016) with most deaths occurring in the first year. In this large SC cohort, the clinical spectrum was heterogeneous with about one-third either male,

            Differences in the Clinical Profile and Outcomes of Typical and Atypical Takotsubo Syndrome: Data From the International Takotsubo Registry.

            Apical ballooning is broadly recognized as the classic form of takotsubo syndrome (TTS). Atypical subtypes of TTS also exist, which constitute about 20% of all cases. To date, clinical profile and course of atypical TTS types have rarely been studied.
