Cardiac thrombi mistaken for metastasis in recurrent melanoma
No full textIntra-cardiac thrombi can be incidentally found in recurrent melanoma and need careful assessment. An 81-year-old woman, with a history of malignant nasopharyngeal melanoma, was evaluated by echocardiography and cardiac magnetic resonance due to the detection of undefined masses localized both in right atrium and ventricle during contrast-enhanced thoraco-abdominal computed tomography

Reversible coronary microvascular dysfunction: a common pathogenetic mechanism in Apical Ballooning or Tako-Tsubo Syndrome
No full textAims To study coronary microvascular dysfunction as possible pathogenetic mechanism in Apical Ballooning Syndrome (ABS). Methods and results Fifteen ABS patients (all women, 68 +/- 14 years) underwent myocardial contrast echocardiography at baseline during adenosine infusion (140 microg/kg/min) and at 1-month follow-up and compared with a group of anterior ST-elevation myocardial infarction (STEMI) patients with similar clinical characteristics. Myocardial perfusion was assessed by contrast score index (CSI) and endocardial length of contrast defect (contrast defect length, CDL), whereas myocardial dysfunction by wall motion score index (WMSI), endocardial length of contractile dysfunction (wall motion defect length, WMDL), and LV ejection fraction (LVEF). At baseline, no difference in myocardial perfusion and dysfunction were present between the two groups. During adenosine challenge, while no changes were observed in STEMI group, in ABS patients CSI, CDL, WMSI, and WMDL significantly decreased compared with baseline (P < 0.001 vs. baseline for all parameters) and LVEF significantly increased (P = 0.01 vs. baseline). At 1-month follow-up, myocardial perfusion and dysfunction completely recovered in ABS patients (P < 0.001 vs. baseline for all parameters), whereas no significant changes were observed in STEMI group. Conclusion Our data strongly suggest that in ABS, irrespectively of its underlying aetiology, acute and reversible coronary microvascular vasoconstriction could represent a common pathophysiological mechanism
