Introduction: In adult population after bicuspid aortic valve, atrial septal defect (ASD) is the most common congenital acyanotic heart disease, with high prevalence in females. Large ASD with pulmonary hypertension (PAH) posted for non-cardiac surgery poses a challenge to anaesthesiologists because intraoperative hypercarbia, hypoxemia, and hyperthermia can result in increased pulmonary vascular resistance (PVR), which can result in shunt reversal, congestive heart failure, and fatal arrhythmias. Case Presentation: We report successful anaesthetic management of 48yrs female case of recurrent astrocytoma posted for craniotomy. Patient was having large ostium secundum ASD (35 mm in diameter), with severe PAH having PASP 75mmhg by TR jet, with dilated RA/RV, moderate TR and LVEF 55% under GA, with titrated induction, avoiding rise in PVR and maintaining systemic vascular resistance (SVR) with vasopressors intraoperatively to avoid shunt reversal. Conclusion: To conclude patients with severe PHT due to large ASD, require meticulous intraoperative management to prevent any rise in PAH, and maintenance of systemic vascular resistance with optimal oxygen delivery and excellent postoperative analgesia for excellent outcome.
