Abstract
Pulmonary hypertension due to delay in presentation, diagnosis, referral, and surgery for septal defects is not uncommon in the developing world and translates into high morbidity and mortality following open heart surgery to close these defects. Leaving a small atrial communication may not always be effective. Extracorporeal membrane oxygenation and inhaled nitric oxide therapy in the immediate postoperative phase may not be available or may not be financially feasible in many institutions which are economically challenged. Unidirectional valved patch is emerging as a new and effective solution to this problem and promises to make at least the immediate postoperative results more predictable in this subset of patients.
