Early pseudoaneurysm formation after the sutureless technique for left ventricular rupture due to acute myocardial infarction.

Left ventricular free wall rupture is a fatal and catastrophic complication after acute myocardial infarction. The sutureless technique with a fibrin tissue-adhesive collagen fleece is reportedly safe and effective in the oozing type of left ventricular free wall rupture. However, late pseudoaneurysm formation after this technique has been reported. We herein report a 65-year-old male patient who presented with pseudoaneurysm formation 8 days after the sutureless technique for the oozing type of left ventricular free wall rupture. Successful repair of the pseudoaneurysm was subsequently performed. Pseudoaneurysm formation should be recognized even early after the sutureless technique.
