(20%) showed hemodynamic relevant MAPCA’s. Those MAPCA’s are often clinically silent, but may cause 2 MAPCA’s were a risk factor for prolonged ICU and congestive heart failure after surgical repair with systemic hospital stay with a longer ventilation time, longer hypoxemia, pulmonary volume overload, left ventricular support with inotropic agents and delayed chest closure. dysfunction and respiratory failure. We suggest an early work-up in the cath lab when facing The aim of our study was to evaluate our patient population for an early postoperative complicated course due to complicated early postoperative course due to MAPCA’s. coronary anomaly or MAPCA’s. 3 Methods 4-year retrospective study at Division of Pediatric Cardiology, Universitiy Children’s Hospital , Zürich. Analysis of clinical data of neonates with simple d-TGA after arterial switch operation with known MAPCA’s complicating the postoperative course.
