Delayed presentation and operation for patients with atrial and ventricular septal defects and pulmonary hypertension are not uncommon in the developing world.^1,2 These patients often have a turbulent postoperative course as the result of pulmonary hypertension. To partially overcome this, a wide variety of unidirectional valved patches have been described.^3-5 These serve to achieve a right-to-left shunt to prevent right ventricular failure in the setting of persistently elevated pulmonary artery pressures. We devised a simple technique for creating a unidirectional valved patch.

Clinical Summary

Routine monitoring, anesthesia, and cardiopulmonary bypass techniques are used. After cardioplegic arrest, the right atrium is opened and the atrial or ventricular septal defect is inspected and sized. A patch of knitted . . . [Full Text of this Article]
