Closure of an atrial septal defect with a one-way flap patch in a patient with severe pulmonary hypertension

An isolated atrial septal defect (ASD) can occasionally go unrecognized for decades and accounts for 25–30% of congenital heart disease cases diagnosed in adulthood. Pulmonary hypertension often develops as a result of a long-lasting, left-to-right shunt and may ultimately be associated with a fixed increase of pulmonary vascular resistance, sometimes rendering these patients inoperable. To reduce the risk of developing postoperative morbidity and possible mortality, we employed our technique of a unidirectional valved patch for the closure of ASD.
