UNLABELLED: Tako-Tsubo cardiomyopathy (TTC) is described as left ventricular (LV) dysfunction with the phenomenon of "apical ballooning", rapidly resolving, without coronary artery stenoses. METHODS: Fifteen patients with TTC and transthoracic echocardiography (TTE) at their admission, were reviewed (2001 to 2006). Follow-up (F/U) TTE was performed in varying intervals. To compare diameters of posterior wall (PW), interventricular septum (IVS), left atrium (LA), LV in end-diastole (LVED) and LV in end-systole (LVES) and valve insufficiencies, patients with comparable F/U are selected. RESULTS: Fourteen patients were female (mean age 69.6 years). Angiography demonstrated LV systolic dysfunction with mean ejection fraction (EF) of 31.3%. In the acute-phase (day 0 to day 3), TTE showed a mean EF of 35.7%, not significantly different from EF obtained in angiography. Short-term F/U was performed in 9 patients after median time-interval of 20 days with an increase to a mean EF of 58.8%. F/U in 2006 has been performed in 10 patients (median time-interval 18.7 months) and showed normal EF. No significant difference in diameters of LA, LVED and LVES could be obtained comparing baseline and long-term data (p=0.493, p=0.790 and p=0.275). PW and IVS were significantly thicker at baseline compared to TTE > or = day 62 of F/U (p=0.003 and p=0.026). At baseline mitral valve insufficiency (MI) was mild in 50.0% and moderate in 12.5%, mild and moderate tricuspid valve insufficiency (TI) was recognized in 50% (25% respectively). MI and TI were regredient in F/U. In three patients an intraventricular systolic flow acceleration could be detected in the acute phase. CONCLUSIONS: Characteristics of TTC, besides transient LV apical ballooning are also a significant change in LV wall thickness and reversible valve insufficiencies.
