Suspension string: a new method of aortic valvuloplasty for aortic insufficiency and ventricular septal defect.
In a 4-year-old boy with ventricular septal defect, severe aortic insufficiency, and mild infundibular stenosis, a new method was used to reconstruct the prolapsed aortic cusp. Two ends of a pledged stitch were passed through the aorta at each side of the right, noncoronary commissure and then through another pledget, and were then tied repeatedly in a row. The length of the row of knots was equal to that of the free edge of left coronary or noncoronary leaflet. The remainder of the stitch was passed through a pledget and then the aortic wall at each side of the left and right coronary commissure to the extraaortic wall pledget and were tied. A suspension string was formed by the row of knots and supported by a Teflon (Dupont Teflon, Wilmington, DE) felt pledget sandwich at each of two commissures. The free margin of the prolapsed cusp was attached to the suspension string by a continuous suture. The concomitant anomalies were corrected. The result was satisfactory.
