Data Supplement
Movie I (htm). All panels of Movie I were acquired using fast gradient echo MR imaging (TrueFISP), depicting typical 2-chamber, 3-chamber, and 4-chamber long-axis views of the patient's heart. The left ventricle is displayed to be enlarged (LVEDD 63 mm, EDV 660 mL, ESV 600 mL) and functionally impaired (LVEF 9%). A large apical aneurysm (10 cm x 8.6 cm) is shown to be filled with thrombotic debris. Interestingly, despite the severely impaired LV function, no signs of pulmonary edema could be found clinically. The right side of the heart appears to be normal, and not even a small pleural effusion was found (4-chamber view).

Movie II (htm). The upper 3 parts of Movie II (labeled "Cine") were acquired using fast gradient echo MR imaging (TrueFISP) before injection of 0.1 mmol/kg Gd-DTPA, and the lower 3 parts (labeled "Contrast") were acquired using inversion recovery (IR FLASH) MR imaging after injection of 0.1 mmol/kg Gd-DTPA. The FISP short-axis views are arranged from basal to apical with a corresponding contrast-enhanced (ce) MR image beneath each slice. The most basal slice depicts a thinned anterior wall with corresponding contrast enhancement in the ceMR slice below (arrows) as sign of chronic myocardial infarction (MI). In the mid slice the thinned anterior wall starts to dilate aneurysmaticaly and the respective ceMR image below shows that the extent of MI (bright, look for arrows) increased towards the lateral wall and the septum. In the dilated anterior area signs of organized Thrombus slowly taking up some contrast (*). The most apical slice is acquired completely within the aneurysmatic apex, showing all ventricle walls thinned and dilated. In the corresponding ceMR image below the complete wall shows contrast hyperenhancement (arrows) as evidence of chronic myocardial infarction. Nearly 50% of the aneurysm cavity is filled with organized thrombus sloly taking up the Gd-DTPA (look for *).
