Transient dynamic subaortic stenosis in premature neonates after patent ductus arteriosus ligation.
We describe 2 premature infants with PDA that did not respond to medical therapy and required surgical ligation. Both infants developed transient dynamic subaortic obstruction that resolved without specific therapy. This may have occurred due to sudden changes in the left ventricular volume.
