Abstract:
A 3.5-kg boy with dilated cardiomyopathy underwent EXCOR left ventricular assist device implantation, which resulted in right ventricular outflow tract obstruction due to the development of an interventricular septal haematoma (IVSH), which required the implantation of an additional right ventricular assist device. Curettage and haemostasis of the IVSH were successfully performed on postoperative day 17. An 11-kg girl with left ventricular non-compaction also underwent EXCOR left ventricular assist device implantation. An IVSH was initially detected on postoperative day 13 without haemodynamic instability. By decreasing the target-activated partial thromboplastin time, the IVSH completely regressed 2 months later.
