Pulmonary autograft replacement of the aortic valve: an evolution of technique.

The use of the patient's pulmonary valve for replacement of the patient's diseased aortic valve was introduced and developed by Mr. Donald Ross. Its demonstrated durability, freedom from thromboembolism, and potential for growth has led to increased utilization of this technique. Modifications of the earlier techniques have led to a reproducible operation with low operative risk and excellent mid-term results.
