Introduction: The presence of pulmonary hypertension (PH) in atrial septal defect (ASD) poses a clinical challenge on whether or not to close the defect. Closing the defect increases the risk of low cardiac output syndrome (LCOS), while leaving the defect open may eventually lead to irreparable shunt reversal, hypoxemia, and death. The implementation of a fenestrated patch may halt LCOS while adding volume to the left heart. Methods: this is an analytical observational study involving patients with ostium secundum defect with PH who were operated on in Dr. Soetomo Hospital between January 2017 and October 2021. The aim of this study is to evaluate the improvement in left ventricular size during both systole and diastole.
